Antioxidants are one of the most important—and most underutilized—steps in a skincare routine. They work by neutralizing free radicals generated by UV exposure, pollution, and environmental stress, helping to prevent the kind of cumulative damage that leads to fine lines, uneven tone, and loss of firmness over time.
SkinCeuticals has built its reputation on antioxidant science, and their vitamin C serums are among the most clinically validated products in professional skincare. Here's a breakdown of the three most popular options and how to choose the right one for your skin.
SkinCeuticals C E Ferulic
CE Ferulic is the gold standard of antioxidant serums—and one of the most talked-about products in professional skincare. It combines 15% pure vitamin C (L-ascorbic acid) with vitamin E and ferulic acid, a combination that has been shown to double the photoprotective benefits of vitamins C and E alone.
With consistent morning use, CE Ferulic helps brighten skin, improve radiance, reduce the appearance of fine lines and wrinkles, and correct uneven skin tone. It's best suited for normal to dry skin types and pairs well with a broad-spectrum SPF.
SkinCeuticals Phloretin CF
Phloretin CF is formulated for normal to oily or combination skin and delivers advanced environmental protection against photoaging. It combines 10% vitamin C with phloretin—a powerful antioxidant derived from apples—and ferulic acid.
Phloretin is particularly effective at neutralizing free radicals and has been shown to help reduce hyperpigmentation and improve skin firmness. The lighter texture of Phloretin CF makes it a better fit for those who find CE Ferulic too rich, while still delivering comparable antioxidant protection.
SkinCeuticals Silymarin CF
Silymarin CF is SkinCeuticals' antioxidant serum designed specifically for oily and acne-prone skin. It combines vitamin C and ferulic acid with silymarin—an antioxidant derived from milk thistle—to protect against environmental damage while actively reducing oil oxidation, a key contributor to breakouts and enlarged pores.
For those with oily or combination skin who have struggled to find a vitamin C serum that doesn't feel heavy or contribute to congestion, Silymarin CF is an excellent option.
Which SkinCeuticals Antioxidant Is Right for You?
All three serums share the same core function—neutralizing environmental damage and supporting healthier, more resilient skin—but they're formulated for different skin types and concerns:
- Normal to dry skin: C E Ferulic
- Normal to oily or combination skin: Phloretin CF
- Oily or acne-prone skin: Silymarin CF
Whichever formula you choose, apply it every morning to clean, dry skin before moisturizer and sunscreen for best results. Antioxidants work synergistically with SPF—together, they provide significantly stronger protection than either step alone.
