Description
INCI Name:Sodium ascorbyl phosphate
Sodium ascorbyl phosphate (SAP) is A derivative of vitamin C.
It is a stable, water-soluble form of vitamin C that functions as an antioxidant.
It is the most stable form of vitamin C, which means it does not oxidize, making it a preferred choice for cosmetic formulations. It is more stable and bioavailable than magnesium ascorbyl phosphate (MAP), ascorbyl palmitate and ascorbic acid (including vitamin C derivatives).
Unlike its powerful brother ascorbic acid, it does not like acidic environments and needs a pH of about 6-7.
It is potentially effective for brightening an uneven skin tone.
It is an antioxidant that reduces oxidative stress by neutralizing free radicals, effectively slowing down the aging process and slowing down the formation of fine lines and wrinkles. SAP has the ability to penetrate the epidermis without causing irritation.
It has the ability to intercept and neutralize free radicals and oxygen species. SAP is an active ingredient that protects against UV damage and improves the photoprotective properties of sunscreens.
This means it prevents sunburn and supports the protective effect of sunscreens. Similar to a tyrosinase inhibitor, SAP has skin-lightening properties by inhibiting melanin production.
SAP is very effective on acne, scars, wrinkles and pigmentation marks. It prevents the development of new acne.
