SkinCeuticals Silymarin CF is the first antioxidant serum clinically formulated for oily and acne-prone skin‚ a medical grade skincare breakthrough that delivers dermatologist recommended antioxidant protection while actively improving the appearance of blemishes and excess oil. Unlike traditional vitamin C serums, this lightweight oil-free formula uses silymarin (milk thistle extract) combined with 0.5% ferulic acid and pure vitamin C to reduce oil oxidation by up to 76%‚ a key factor in acne formation. Oil oxidation control: Clinically reduces sebum oxidation, a primary contributor to acne breakouts and blackheads Antioxidant environmental defense: Shields skin from UV and pollution-induced free radical damage without clogging pores Pore minimization: Visibly reduces the appearance of enlarged pores with continued use Anti aging skincare benefits: Addresses early fine lines and loss of firmness in younger, oilier skin types Clarifying and brightening: Improves overall skin clarity and reduces dullness for a more even complexion Best suited for patients with oily, combination, or acne-prone skin who have historically been excluded from antioxidant serum routines due to heavy or pore-clogging formulas. Dermatologist recommended for use as part of a daily acne treatment skincare regimen. Key Ingredients: Silymarin (Milk Thistle), 0.5% Ferulic Acid, Vitamin C (L-Ascorbic Acid), Salicylic Acid. Usage: Apply a few drops to cleansed skin each morning before sunscreen. Non-comedogenic and oil-free.
