An Introduction to peptides

Peptides are short chains of amino acids, usually containing 2-50 amino acids. Although protein is mainly composed of amino acids, it contains more amino acids than peptides. Therefore, peptides may be more easily absorbed by the body than proteins for that they are smaller and easier to break down. They can penetrate the skin and intestines more easily and thus enter the bloodstream faster.

Some common types of peptide supplements

  • Collagen peptides. Good for skin health and reverse the effects of aging.
  • Creatine peptides. Mainly used to enhance strength and muscle mass, effective supplements for bodybuilding.
  • Tanning peptides. It can stimulate the production of melanin.

Importance of peptides

Many active substances in the human body exist in the form of peptides. Peptides are involved in the human body’s hormones, nerves, cell growth and reproduction. Its importance lies in the physiological functions of various system and cells in the body, activating related enzymes in the body, promoting the permeability of the intermediate metabolic membrane, or by controlling DNA transcription or affecting specific protein synthesis, and ultimately producing specific physiological effects.

Peptides are important substances involved in a variety of cell functions in the human body. Peptides can synthesize cells and regulate the functions activities of cells. Peptides act as neurotransmitters in the human body to transmit information. Peptides can be used as a means of transportation in the human body to transport various nutrients, vitamins, biotin, calcium and trace elements beneficial to the human body to the cells, organs and tissues of the human body. As an important physiological regulator of the human body, peptides can comprehensively regulate the physiological function of the human body, enhance and exert the physiological activity of the human body, and it has important biological functions.

Why Want to Get a Tan

  • Look better. In many countries, they are beautiful with bronzed and wheaten skin, and they think that this kind of skin tone is healthier.
  • Feel better. Tanning can make body produce more dopamine and make people feel more happy. In addition, during your tanning process, the warm and soothing experience will also make your mood better.
  • Supplement vitamin D. Vitamin D deficiency can lead to depression, diabetes and even autoimmune diseases. Getting enough Vitamin D is extremely important for health.

Principle of tanning

When thermal radiation or sunlight irradiates the skin, it stimulates and activates the melanocytes located in the basal layer. They exist in the basal cells at a ratio of 10:1. This cell has a dendritic appearance and shuttles in the epidermal cells. Melanocytes contain pigment particles, which synthesize melanosomes in the coarse endoplasmic reticulum, which will catalyze tyrosine for a series of reactions, and produce melanin protein. At the same time, tyrosinase will lose its activity and act as a transport job to transfer it to keratinocytes. . The more melanin protein is transferred into keratinocytes, the darker the skin tone.

What is melanin

Melanin is a complex polymer derived from the amino acid tyrosine. Melanin is responsible for determining the color of skin and hair, and is present in the skin to varying degrees. Tyrosine is only found in special cells called melanocytes. In melanocytes, tiny particles of melanin are contained in vesicles called melanosomes. These melanosomes leave the melanocytes and enter other cells in the epidermis. Melanin deposits are mainly brown or black, which determines the skin pigmentation, which depends on the number and distribution of melanosomes. Melanin deposits are mainly brown or black, which determines the skin pigmentation, which depends on the number and distribution of melanosomes.

Ultraviolet rays are an external stimulates that the human body is exposed to for a long time, and it is the main physiological stimulus for the proliferation of human melanocytes and the increase of skin pigmentation. Therefore, many people sunbathe for tanning.

About the skin color types

There are considerable differences in individual skin color. Before tanning, knowing about the your skin type can simplify your tanning work and help identify the skin types most vulnerable to UV rays.

The Fitzpatrick classification

  • Skin Type I – Pale white skin. It burns easily and generally doesn’t tan at all.
  • Skin Type II – Fair skin. It burns easily and usually turns a small tan in summer.
  • Skin Type III – Darker white skin. It can burn under strong direct sunlight and then tan better.
  • Skin Type IV – Light brown skin. Almost no sunburn, even after a lot of sun exposure, usually tan well.
  • Skin Type V – Brown skin. Rarely burns, tans darkly easily.
  • Skin Type VI – Dark brown or black skin. Never burns, always tans darkly.

How do Melanotan tan peptides work

Melanotan injections mainly work by replicating α- melanocyte stimulating hormone in the body. This hormone binds to melanocortin receptors and stimulates the production of melanin in skin cells. That is to say, even under a small amount of ultraviolet radiation, the release of α-MSH will stimulate the natural increase of melanin production by melanocytes in the skin. The more melanin produced by skin cells, the darker your skin will be. The tanning peptide induces our body’s own natural pigment system through the process of melanin production, which can achieve tanning before any harmful ultraviolet rays, thereby reducing the risk of any skin damage.

How long does it take to see the effect of Melanotan

It depends on which product you are using. The strengths of I and II are different, and the effects produced are also different. In addition, some other aspects will also have a great impact on the effect, such as, the dosage of the injection, the natural skin color, whether other tanning methods are performed at the same time, etc.

How long will the tan last

The tan achieved with melanotan peptide for tanning can last much longer than the normal tan. A person who achieves tanning through sunbathing will lose most of his tan within a month if he stops sunbathing. But if they have been using tanning peptides for tanning purposes and continue to maintain after the effect is achieved, they will still have most of the tan after 3 months.

Benefits of using tanning peptides

  • We usually know that tanning is mainly achieved by sunbathing. The peptides for tanning can enable you to achieve the purpose of tanning without having to spend a few hours in the sun and without a dangerous tanning bed.
  • Tanning peptides can provide protection against burning in the sun. Peptides are amino acids, and we can deliver them to the body to stimulate different physiological changes. Melanotan can increase your skin’s melanin production to provide a tan without using chemical sprays or harmful UV tanning beds to damage your skin.
  • When a person spends a period of time in the sun, they are exposed to ultraviolet radiation, which can cause damage to skin cells. Sunbeds have a high risk of skin cancer.
  • Injectable tanning peptides will increase the melanin in the skin. It can produce a tan appearance when there is no or very limited sun exposure. And may have a certain protective effect on skin cancer.
  • Melanotan has a semi-permanent effect of darkening the skin, just like being tanned by the sun.
  • Melanotan is used to treat skin problems, including vitiligo and erythropoietic protoporphyria. This will affect the appearance and influence of the skin, especially on the sun.

Are tanning peptides safe

  • There may be some side effects and dangers, which may include nausea and vomiting, acne, stomach pain, eye disease, blood disease and even heart problems.
  • If you do not pay attention to hygiene and safety during injection, it may cause the spread of blood-borne diseases such as hepatitis or AIDS.
  • If an untrained person injects it, it may cause skin and tissue damage.

The dangers of tanning

  • Ultraviolet radiation can damage the DNA of skin cells, causing the skin to grow abnormally and develop into melanoma.Ultraviolet radiation can damage the DNA of skin cells, causing the skin to grow abnormally and develop into melanoma.
  • Tanning also increases the risk of non-melanoma, such as basal cell carcinoma and squamous cell carcinoma.  These more common skin cancers occur in areas of the body that are exposed to sunlight, such as the face, ears, lips, and back of hands. Although these lesions rarely spread, they can cause disfigurement. In some cases, they can also be fatal.
  • Ultraviolet rays can damage the eyes, causing cataracts, macular degeneration, and growth around the eyes.
  • Everyone, regardless of skin color or overall health, may have immune system suppression due to excessive exposure to ultraviolet light.The destruction of the immune system affects your body’s natural defenses against viruses, diseases and other toxins. If this happens, you are more likely to be infected and more likely to have a more serious condition.

How to protect the skin from damage while tanning

People with lighter skin have less melanin and may burn or turn red in the sun. People with darker skin have more melanin and become darker after tanning. However, people with darker skin are still at risk of sunburn and skin cancer. Melanin is naturally produced by the body to protect the deep layer of the skin from damage. But remember, even if you are a skin type that is not prone to sunburn, the sun can still cause damage to your skin. Therefore, if you need to use ultraviolet rays to tan, you must also protect your skin at the same time.

  1. Apply sunscreen with a SPF of at least 30 on your skin and lips.
  2. Reapply sunscreen every two hours and after entering the water.
  3. Apply SPF to the scalp, toes, ears and other places that are easily to miss.
  4. Turn over frequently so you can tan evenly without burning.
  5. Drink more water.
  6. Wear a hat and sunglasses to protect your eyes.

How to use peptides for tanning

This peptide is usually provided in the form of a lyophilized powder, which is sealed and stored in a sterile vial. Before injection, you need to dilute the powder in sterile powder. This needs to be done at home, because if there is no continuous cooling after mixing, the liquid will quickly deteriorate and become less reliable.

The lyophilized powder is made by freezing the water in the liquid medicine in advance by the vacuum freeze-drying method of the freeze dryer, and then sublimating the frozen moisture in the medicinal solution in a vacuum aseptic environment to freeze-dry it. In short, the water in the liquid medicine is drained in a low temperature environment to retain its original medicine effect. For drying heat-sensitive products and materials that need to maintain biological activity, freeze-drying is an effective method.

Benefits of lyophilized powder

The method effectively prevents changes in the physical, chemical and biological properties of the products, causes less damage to the biological tissue, cell structure and characteristics, makes it quickly enter a dormant state. This method can effectively protect the stability of the active ingredients of any heat-sensitive pharmaceutical biological products, such as proteins and microorganisms.

Secondly, the lyophilized powder has a loose shape and basically no change in color after drying. After adding water, it can quickly dissolve and restore the physical and chemical properties and biological activity of the original aqueous solution.

Third, since the drying is carried out under vacuum conditions, it has a good protective effect on some easily oxidized substances.

Fourth, the product has a very low moisture content after freeze-drying, which improves the stability of the product and reduces the chance of contamination, which not only facilitates transportation but also extends the shelf life of the product.

The most important equipment required to use peptides for tanning is insulin syringe. Insulin syringes usually have two main sizes, measured in global units(IU), 10IU=0.1ml, 100IU=1ml. As with any injection, disinfect the injection site with alcohol swab before injection.

Sterile water belongs to a class of medicines called sterile irrigation solution, which can be used alone or together with other medicines. Sterile water usually refers to the treatment of bacteria-containing water through physical methods to obtain bacteria-free water. The treatment methods include steam method, UHT thermal method, ultraviolet sterilization, ozone method and physical filtration method, etc. The water obtained by killing and filtering the microorganisms in the water is sterile water, and the inorganic salts in the water won’t generally decrease.

  1. Remove the cap of the tan peptide vial.
  2. Unpack the disposable syringe.
  3. Remove the cap of the sterile water bottle.
  4. Grasp the syringe and pierce the needle through the stopper of the sterile water bottle and turn it upside down. Pull back the plunger of syringe. After injecting an appropriate amount of the sterile water, carefully remove the needle from the vial.
  5. Insert the syringe containing sterile water into the vial of lyophilizedpowder through the center of the cap. Align the needle of the syringe with one side of the vial, slowly depress the plunger, and inject sterile water. Once the syringe is empty, gently remove the syringe.
  6. To ensure that the lyophilized powder is evenly mixed with sterile water, you can slowly roll the vial with your fingers. Avoid shaking the solution.
  1. Generally, subcutaneous injections are performed through the fat layer of the tissues around the belly button.
  2. Find the injection site in the abdominal area, a few centimeters from the belly button. And clean it with cotton swab.
  3. Pinch the fat tissue to avoid injecting it into your muscles.
  4. Insert the needle at a 90-degree angle into the area you are pinching. Don’t remove the needle before injecting the entire syringe solution.
  5. If available, use another swab to remove blood from the injection site.


Many websites may tell you different dosage standards. What we want to tell you is that you need to test your body’s tolerance first and choose the appropriate dosage based on your basic situation and the doctors’ recommendation.

The ideal dosage is o.1ml of the solution per day to minimize side effects. Inject everyday until the desired color is achieved, and then inject once or twice a week to maintain the color. The effect will be more pronounced when used tan peptides with the skin exposed to ultraviolet rays, sunbathing or tanning beds.

Some other tanning methods

Nasal spray tanning

Nasal spray tanning is a more convenient form of tanning peptides. But according to people with experience, its effect isn’t as good as injecting tanning peptides because of its low absorption rate.

Natural tan

  1. Choose a sunscreen product with a low SPF. In order to get tanned quickly, but to avoid sunburn, you need to use a low SPF lotion or sunscreen to ensure protection against harmful rays from the sun. Ideally, choose a sunscreen with an SPF of 4-15 according to the intensity of your tan.
  2. The most effective method for tanning is to choose a sunscreen spray or sunscreen. Because they have a watery texture, can penetrate the skin thoroughly.
  3. Apply lipstick with an SPF of at least 15 if you don’t want your lips to become brown, dry and cracked.
  4. After applying sunscreen, apply a layer of natural oil to the skin. This will attract sunlight and make your skin look shiny. Apply these natural oils before going out in the sun, and rinse off with soap and water after the sun.
  1. Turn around frequently to get an even tan. A good rule of thumb is to turn 1/4 every half an hour. Make sure to move your arms and legs frequently to avoid embarrassing sun marks.
  2. Choose the right time to bask in the sun.
  3. Expose yourself to direct sunlight. As the sun moves in the sky, you also need to move your towel or chair to ensure that you are always exposed to direct sunlight.
  4. This will magnify and concentrate sunlight on your skin. Place the reflector on your waist and tilt it at a 45-degree angle until the sun shines directly on your body.
  5. Lying on a floating device in the water, because water can attract and reflect light, lying in or near the water can help you absorb as much sunlight as possible.
  6. Apply some sunscreen lotion or sunscreen every two hours or after contact with water. Always make sure you apply a low SPF sunscreen oil or lotion to protect yourself from the
  7. After tanning, apply an aloe vera moisturizing cream or lotion.

Use tanning lotion

  1. Choose a tanning product. Tanning products include lotions, creams, gels, foams, sprays, and oils. Follow the prompts and apply the tanning product of your choice evenly, making sure to cover all the skin.
  2. Wear gloves because you will use your hands to apply lotion to other parts of your body, so your hands will absorb more lotion or oil than other parts. Use disposable medical gloves and wear them when applying to avoid darker hands than other parts. Be sure to apply some lotion or oil on your hands after applying other parts.
  3. Remember to apply evenly. Don’t forget the places that you usually can’t see.
  4. Apply it every day until you reach your ideal skin tone. In order to achieve the desired skin tone effect, applying tanning lotion in the morning should be enough, but you can also apply it once in the morning and once in the evening to speed up the tanning process.

Use skin pigment spray

  1. Tanning principle. Like tanning lotion, skin pigment sprays also contain the three-carbon sugar dihydroxyacetone (DHA), which can react with amino acids to increase skin color. Skin pigment sprays usually work better. However, to achieve the desired level of tan, you need to apply one to three layers of spray every time.
  2. Choose the right product. It is recommended to choose a skin pigment spray product that contains a lower proportion of DHA, so that the skin color can be gradually darkened.In addition, use products containing erythrulose. Erythrulose is a sugar compound found in raspberries, which allows your skin to maintain its color longer, while producing a healthy glow.
  3. Determine how many sprays you need to applyaccording to your own situation. For people with fair skin, a layer of spray is enough to produce a beautiful glow. For people with tan skin, several coats may be required. Slowly increase the pigment gradually until you reach the color you expect.
  4. A professional person is needed to help you apply the spray to your body.
  5. Apply the spray every one to two weeks. Depending on the intensity of the tan and your original skin tone, the effect of the spray can last for 5 to 10 days.

Use indoor sunbeds

  1. Principle of tanning. Indoor sunbeds use ultraviolet light bulbs to emit ultraviolet rays similar to sunlight. Indoor sunbeds have been proven to increase your risk of skin cancer. Dermatologists strongly advise against using indoor sunbeds. However, if you need to get a tan right away, this is the fastest and most effective method. If possible, avoid harmful UV rays.
  2. Wear goggles. Be sure to wear special goggles when tanning on the indoor sunbed.
  3. Pay attention to the length of time. If this is your first tanning, you should start with relatively little time. People usually spend 8 to 20 minutes in indoor sunbeds. If you have very fair skin, choose a shorter time. If you have darker skin, it will take more time.

Some tips on tanning

  1. Always be careful about the dangers associated with tanning. There are many risks related to tanning, such as, skin cancer, chemical reaction, etc. Avoid prolonged exposure to indoor sunbeds or prolonged exposure to the sun without proper UVA and UVB protection.
  2. Keep the skin moisturized. After tanning, apply moisturizing lotion and drink plenty of water.
  3. Always wear gloves when applying tanning lotion, unless you want orange or brown palms.
  4. Always wear googles to protect your eyes when using skin pigment sprays.
  5. Wear a hat and sunglasses when you are outdoors in the sun to protect the sensitive skin on your face and eyes.
  6. Don’t get too tanned to avoid sunburn. Burning and peeling skin is not attractive at all.
  7. Choose a good tanning product. A good tanning lotion can achieve the same tanning effect without the risk of skin damage.
  8. Be prepared before and after tanning. Preparing for skin protection and tanning before heading outdoors can help maintain a longer tan. Try exfoliating before tanning. Skin without exfoliation is more likely to peel off. Using aloe vera gel after tanning can also help tan for longer.
  9. Don’t stay outdoors for longer than the time that skin produces melanin. Melanin is the pigment responsible for tanning. Everyone has a melanin cut-off point, usually 2 to 3 hours. If you tan more than that point, you will cause damage to your skin.
  10. Choose the tanning time wisely. If your goal is to get a quick tan, the sun is usually at its strongest between noon and 3pm, but this exposure may increase the risk of skin cancer. If you have very fair skin, it is best to get a tan in the morning or after 3 pm to avoid sunburn.
  11. Paying attention to the food you eat can also help better tan.Eat foods contain β-carotene, such as carrots, sweet potatoes and kale, which can help you tan without burning. Studies have shown that β-carotene can help reduce the incidence of photosensitivity diseases. Eat foods rich in lycopene, such as tomatoes, guava, and watermelon. Studies have found that lycopene helps to protect the skin from UV damage naturally.
