Product Information
The Sunday Riley C.E.O. 15% Vitamin C Brightening Serum is an ultra-potent, fast-absorbing treatment specifically engineered to rapidly fight the look of dullness, dark spots, and signs of premature aging, giving you an immediate, brilliant glow. It stands out in the Vitamin C category by using a highly stable, advanced form of the ingredient.
???? High-Potency, Stable Vitamin C
The secret to this serum's efficacy is the use of 15% Tetrahexyldecyl Ascorbate (THD Ascorbate). This is a sophisticated, oil-soluble form of Vitamin C that is renowned for being extremely stable and easily absorbed by the skin. Unlike many traditional, volatile forms of Vitamin C (L-Ascorbic Acid), THD Ascorbate remains potent longer and is far less likely to cause irritation, making it suitable for all skin types, including sensitive skin.
This powerful form of Vitamin C works to deliver comprehensive benefits:
Intense Brightening: Rapidly diminishes the appearance of dark spots, hyperpigmentation, and discolorations, restoring clarity and boosting skin radiance.
Anti-Aging Action: Helps visibly improve loss of firmness, the look of lines and wrinkles, and restores youthful skin bounce.
Antioxidant Protection: Provides powerful antioxidant support to help fight the visible signs of aging caused by environmental stressors like pollution and UV exposure.
???? Hydrating & Pore-Refining Support
The C.E.O. serum is more than just a Vitamin C treatment; it is a complex formula that supports overall skin health:
Phytosterols Complex: Isolated from soybeans, these concentrated plant sterols help to reduce the look of redness and signs of skin sensitivity, soothing and calming the complexion.
Saccharide Isomerate Extract: This complex, corn-derived ingredient acts to diminish the appearance of pores while deeply reinforcing the skin's natural moisture barrier, resulting in a smoother, more supple texture.
Glycolic Acid: An Alpha Hydroxy Acid (AHA) included to provide mild, gentle refinement of the skin's texture, supporting natural cell turnover for an added glow.
