Sodium Ascorbyl Phosphate

INCI: Sodium Ascorbyl Phosphate (SAP)

Sodium Ascorbyl Phosphate (SAP) is a naturally occurring water-soluble derivative of vitamin C. It is the most stable form of vitamin C, which means it does not oxidise. It is the most stable form of vitamin C, which means it does not oxidise, making it a preferred choice for cosmetic formulations. It is more stable and bioavailable than magnesium ascorbyl phosphate (MAP), ascorbyl palmitate and ascorbic acid (among other vitamin C derivatives).
Unlike its powerful brother ascorbic acid, it does not like acidic environments and requires a pH of around 6-7. It is an antioxidant that reduces oxidative stress by neutralising free radicals, effectively slowing the ageing process and slowing the formation of fine lines and wrinkles.  SAP has the ability to penetrate the epidermis without causing irritation.

Application: Anti-aging
We all know that UVA and UVB radiation from sun exposure causes degenerative effects that accelerate the aging process. Fortunately, SAP has the ability to scavenge free radicals and oxygen species and render them harmless. SAP is an active ingredient that protects against UV damage and improves the photoprotective properties of sunscreens. This means it prevents sunburn and supports sunscreens in their protective effect.  Similar to a tyrosinase inhibitor, SAP has skin-lightening properties by inhibiting melanin production. Natural acne fighter.
In a vitro study, a moderate 1% concentration of SAP was shown to have powerful antimicrobial effects against acne for 8 hours!
Furthermore, it was found that a 5% SAP lotion used for 12 weeks gave excellent results in 76.9% of patients, which is significantly higher than other prescribed acne treatments. Especially since there are NO side effects with these treatments. As a result, sebum oxidation was reduced by up to 40%!
In addition, other clinical studies have shown SAP to be more effective than 5% benzoyl peroxide, 1% clindamycin phosphate, 0.1% adapalene
