Decapeptide-12 is an oligopeptide that is made up of just 10 amino acids. This oligopeptide is known for its anti-tyrosinase activity. Tyrosinase is accountable for producing melanin in the skin. Decapeptide 12 connects to tyrosinase and prevents it from catalyzing the oxidation of phenols – the initial step in melanin creation. It’s able to interfere with tyrosinase and lighten skin.
Decapeptide-12 is an oligopeptide that is made up of just 12 amino acids. This oligopeptide is known for its anti-tyrosinase activity. Tyrosinase is found in plant and animal tissues and is responsible for catalyzing melanin and other pigments. Decapeptide-12 is being investigated for its possible ability to reduce skin darkening. It’s able to interfere with tyrosinase and lighten skin in animal models.

Much research on decapeptide12 centers around its skin lightening effects.

An animal study investigating the safety and efficacy of topical decapeptide-12 in photodamage discovered that the peptide reduced skin pigmentation significantly. The results showed that approximately 40% of test subjects in the study achieved a 100% reduction in hyperpigmentation following 12 weeks.
Meanwhile, 15% of the subjects moved from grade 3 photodamage to grade 1. As for those with grade 4 photodamage (the most severe form), they experienced only slight improvement to grade 3 after the treatment period.
In another study, 100% of mice suffering from melasma saw a drastic change in their skin after decapeptide-12 treatment.
Research shows that decapeptide 12 is around 17 times more powerful than previous treatments for hyperpigmentation.
While the decapeptide 12 studies continue, it is not yet included in commercial skincare products for hyperpigmentation. With more extensive research, decapeptide-12 for sale over the counter should be a possibility.
Decapeptide-12 reduces the appearance of age spots, uneven skin tone, sun spots, and photo damage as research on animals has shown. However, researchers conclude that it comes without the typical side effects of other brighteners like redness, itching, and irritation.
Scientists need to devote more time into investigating decapeptide-12 and its potential side effects. Overall, it is considered a relatively safe product which offers a plethora of potent anti-hyperpigmentation effects.
With more research, decapeptide 12 to buy will be available to purchase for all besides scientific researchers. It should someday become a notable brightening agent.
With decapeptide-12 powder as a product, it can be added in the final stage of cosmetics production, or mixed with skin care products after dissolution, and it is easy to operate and has high safety. Commonly used in skin lightening cream, skin lightening foundation, pressed powder, freckle cream (sunburn, freckles).

Product Mechanism of Action
Tyrosinase has a unique dual catalytic function and is a key enzyme in melanin synthesis in vivo, which is closely related to human aging. Abnormal overexpression can lead to pigmentation diseases in the human body. Tyrosinase inhibitors can treat the currently common pigmented skin diseases such as freckles, chloasma, and senile plaques. Among the popular whitening cosmetics on the market, arbutin, vitamin C derivatives, kojic acid and its derivatives, green tea extract, licorice extract, and other traditional Chinese medicine extracts are all tyrosinase inhibitors, mainly by inhibiting the ability of tyrosinase to inhibit the synthesis of melanin, thereby exerting a whitening effect.

Tyrosinase is the enzyme that catalyzes the first two steps (and possibly the fifth) of the biochemical synthesis of melanin. Some researchers showed that decapeptide 12 was nearly a 17-fold more potent tyrosinase inhibitor than hydroquinone and that unlike hydroquinone, it did not cause melanocyte cytotoxicity. A small pilot clinical study further demonstrated that 0.01% decapeptide 12, formulated in an inert cream base, diminished the appearance of recalcitrant melasma by 40% and 50% after 12 and 16 weeks of twice-daily application, respectively.

Decapeptide 12 inhibits tyrosinase synthesis, thereby effectively (40%) reducing melanin production. It can maximally dilute chloasma, freckles, age spots, sun spots, uneven skin tone and light injury caused by excessive pigmentation. And Lumixyl Decapeptide 12 has no hydroquinone toxicity and side-effects which some other whitening ingredients have, such as allergies, irritation, and redness.
