Due to the love of whitening products by female friends, the whitening product craft has always been cosmetics OEM Popular development projects from manufacturers.Then cosmetics OEM What are the manufacturers' production processes for whitening products?
Cosmetics OEM Manufacturers basically reduce skin pigment by three processes: inhibiting factors that cause darkening of the skin and accelerating the metabolism of dark skin; or inhibiting the activity of tyrosine enzymes that produce black pigments to achieve the effect of whitening skin.
The first process is to reduce melanin production, similar to "prevention is better than treatment": cosmetics OEM The manufacturer uses sunscreen to make the skin whiter due to the lack of melanin-generated stimulation.Therefore, sun protection factors are added to this type of whitening product formula.
cosmetic OEM The second whitening process commonly used by manufacturers is to accelerate the metabolism of stratum corneum cells that have already developed pigmentation, through αHydroxy acids and A Alcohol can promote skin metabolism.Eliminate cells that have already developed pigmentation to make the skin look brighter and can also make the constantly renewed grass-root cells accelerate their growth and division.In this way, the number of melanocytes entering adjacent cells will be smaller and the skin will become significantly whiter.
The third type is to reduce the biosynthesis of new pigments: Regarding the action process of such ingredients, most of the inclusion components of the products sold on the market work by inhibiting tyrosine enzymes.Usually such derivatives cannot have both safety and efficacy.
Anyway, cosmetics OEM The efficacy of the whitening formula used by the manufacturer mainly depends on the type of ingredients contained, and people can evaluate it through test tubes and human tests.However, research results show that the nursing effects produced by combining several active ingredients can be higher than the sum of the effects of a single ingredient.
