Potassium Methoxysalicylate can reduce melanin deposition by inhibiting melanin production and accelerating keratinocyte metabolism. It whitens and smooths the skin safely, with no irritation.

In the study of whitening ingredients, a very important part is, of course, the analysis of the actual production of melanin and the inhibition of tyrosinase. 4msk can inhibit the production of melanin in a certain concentration and environment. It is suitable for all kinds of skin care products. It is recommended to be used in formulas such as whitening, freckle removal and smooth skin. potassium methoxysalicylate   is widely used in many antioxidant,whitening skin care   products because of its strong  function

Its standard Chinese name is potassium methoxysalicylate, also known as 4-MSK. It is an effective medicinal whitening ingredient that has been popular in whitening products in recent years. It was approved by the Ministry of Health in 2007 for use as a cosmetic raw material.

4-MSK has a direct inhibitory effect on the production of melanin, and also has an effect on the proliferation and differentiation of keratinocytes. These two effects have a defensive effect on both the production and release of melanin that causes excessive melanin deposition in the skin.

4-MSK not only has the effect of inhibiting melanin production that other whitening ingredients have, but also has the effect of regulating the imbalance of keratinocyte proliferation and differentiation, thereby promoting the smooth release of excess melanin deposited in the skin and improving the darkening of the skin.

We tested samples containing 1% to 5% 4-MSK, which had a concentration-dependent protective effect on ultraviolet-induced pigmentation. No skin abnormalities caused by the use of 4-MSK were found during the test.
