Vitamin C Compound
A stable vitamin C derivative (ascorbic acid ether) used in skincare for antioxidant support, brightening, and helping reduce the look of hyperpigmentation. It is more oil- and oxidation-resistant than pure L-ascorbic acid, and is commonly used in leave-on serums and creams.

Interactions
incompatible with: May increase irritation when layered with retinoids, AHAs, BHAs, or benzoyl peroxide., Can be used with niacinamide in most modern formulas, but sensitive users may prefer separating potent actives to reduce irritation., Avoid combining multiple low-pH exfoliating/acidic products in the same routine if your skin is reactive.
Risks & Warnings
Can still sting or irritate, especially on compromised or very sensitive skin. Rare allergic contact dermatitis has been reported. As with other vitamin C actives, formulas may be more irritating at low pH or when layered with other strong actives.
