Pearl powder is a powder made of shellfish pearls. The main components are calcium carbonate, amino acids and trace elements. It contains more than 18 kinds of amino acids needed by the human body and 9 kinds of amino acids that the human body cannot manufacture by itself. Pearl powder has been a rare beauty and moisturizing treasure since ancient times.

Tyrosinase is an important catalytic enzyme in the process of melanin production. Kojic acid​ can chelate with copper ions in tyrosinase, thereby inactivating the enzyme, thereby reducing the formation of melanin. It is often used in beauty products for whitening, lightening, and removing acne marks.

Decapeptide-12 (Lumixyl) is a cosmetic raw material that inhibits melanin formation, lightens pigmentation, reduces pigmentation, and evens and brightens skin tone. It was developed by dermatology researchers at Stanford University. A new peptide with tyrosinase (tyrosinase promotes the overproduction of melanin, which leads to uneven pigmentation, dark spots, etc.) activity.

Allantoin is an imidazole heterocyclic compound, a derivative of uric acid, and is an inherent component of human skin. It can be used directly or as an additive component.

Shea butter grows on a plant called "shea butter" in Africa. To grow a fruit that can be extracted from shea butter, the shea butter tree must be at least 45 to 50 years old before it can be extracted from the fruit.

Phenylethyl resorcinol has excellent skin whitening effect, can effectively inhibit the activity of B16V cells to synthesize melanin, improve uneven skin tone, and reduce skin coloration caused by ultraviolet radiation. It is also an excellent antioxidant and has anti-wrinkle properties.

UVB has a short wavelength and UVA has a long wavelength. Therefore, UVB energy is large, and it mainly destroys the epidermis, but UVB consumes almost the same amount of UVB through the epidermis, and not much can reach the dermis. And UVA not only destroys the epidermis, but also easily reaches the dermis to continue to destroy.

N-acetylneuraminic acid, also known as sialic acid (SA), bird's nest acid, is a naturally occurring amino sugar, which was originally isolated from bovine submandibular adenomucin, hence the name sialic acid. Sialic acid is a nine-carbon monosaccharide derivative containing an amino group, and is a general term for all N- or O-derivatives of neuraminic acid or keto-deoxynonyluronic acid (KDN).

The research results show that silk has skin affinity, and the sericin that protects the silk thread is composed of natural moisturizing factor (NMF) in the stratum corneum of human skin. The ingredients are similar.

The best inhibitory effect on tyrosinase activity is deoxyarbutin [p-(tetrahydro-2H-pyran-2-oxy)phenol], which is 10 times more effective against melanin than hydroquinone. Acid 150 times, β-arbutin 350 times, α-arbutin 38.5 times. However, deoxyarbutin also has a major disadvantage, that is, it is unstable to light and heat in an aqueous solution, so there are still relatively few products using it on the market.

Tetrapeptide-30 inhibits the gene expression of tyrosinase and reduces the amount of tyrosinase; inhibits melanocyte activation and reduces melanin production by reducing melanin α-MSH and melanin precursor POMC. In human keratinocytes, it can significantly reduce UVB-induced mRNA expression of interleukins IL-6, IL-8 and TNF-α.

What is ergothioneine?Ergothioneine (mercaptohistidine trimethyl inner salt, ergothioneine, EGT) is a natural antioxidant that can protect cells in the human body and is an important active substance in the body.
