SkinCeuticals Silymarin CF: Vitamin C Antioxidant Protection Made for Oily, Blemish-Prone Skin
SkinCeuticals Silymarin CF is an oil-free morning vitamin C serum designed for people whose skin is oily or prone to blemishes, the group most likely to skip an antioxidant for fear of breakouts. It defends against environmental aggressors while reducing oiliness, refining the look of pores and texture, and improving clarity, radiance, uneven tone, and fine lines.
The formula combines 15% L-ascorbic acid, 0.5% ferulic acid, 0.5% salicylic acid, and 0.5% silymarin, a purified antioxidant from milk thistle seeds. SkinCeuticals explains that silymarin helps prevent oil oxidation, a process the brand links to breakouts and early visible aging, and reports that the formula is clinically demonstrated to reduce oil oxidation by up to 76%.
In an 8-week brand study, average results included a 27% reduction in blemishes, a 38% improvement in skin texture, and a 25% improvement in skin clarity. The serum is free of oil, dye, and silicones, and comes in a TSA approved 30 ml bottle. Individual results vary.

FAQ
What does SkinCeuticals Silymarin CF do?
It is a vitamin C serum for oily skin that protects against free radicals, reduces oiliness, and helps lower the appearance of blemishes. SkinCeuticals also reports improvements in clarity, texture, tone evenness, and fine lines.
What skin types is Silymarin CF best for?
SkinCeuticals positions Silymarin CF for oily and blemish-prone skin. If your skin is sensitive or you are new to vitamin C, the brand's gentler option may be a better starting point (see the comparison below).
Where does silymarin come from?
Silymarin is extracted from the seeds of the milk thistle plant. In Silymarin CF it works alongside vitamin C and ferulic acid as an antioxidant that helps prevent oil oxidation.
Is vitamin C good for oily skin?
Yes. SkinCeuticals explains that the antioxidant and anti-inflammatory properties of vitamin C help reduce blemishes by protecting against free radical damage from UVA/UVB rays and other environmental factors. Silymarin CF delivers that protection in an oil-free formula.
How is Silymarin CF different from Serum 10?
Both serums are built on L-ascorbic acid and ferulic acid, but at different strengths. Silymarin CF uses 15% L-ascorbic acid and 0.5% ferulic acid plus 0.5% silymarin and 0.5% salicylic acid, while SkinCeuticals Serum 10 uses 10% L-ascorbic acid and 0.2% ferulic acid, which SkinCeuticals positions as milder for sensitive skin.
Can Silymarin CF be used with retinol or niacinamide?
Yes to both. SkinCeuticals says vitamin C in the morning and retinol at night work together to improve the look of skin, and that Silymarin CF pairs well with niacinamide to neutralize free radicals, help retain moisture, and reduce the look of blemishes.
What can I layer with Silymarin CF?
Apply it first after cleansing and toning, then follow with corrective serums and sunscreen. For adults dealing with breakouts and visible aging, SkinCeuticals Blemish + Age Defense is designed to go on after a SkinCeuticals vitamin C serum in the morning. The brand also notes that pairing Silymarin CF with retexturing treatments such as light therapy, chemical peels, or microneedling can significantly improve the look of skin.
