A breakthrough combination antioxidant serum for oily and blemish-prone skin combines 0.5% silymarin (milk thistle extract), 15% l-corbic acid, 0.5% ferulic acid, and 0.5% salicylic acid to help prevent oil oxidation that can lead to breakouts, and visible signs of aging. This oil-free formula is clinically demonstrated to reduce oiliness, refine skin texture, and visibly improve skin clarity and fine lines.

Clinical Study Results
Study A
Silymarin CF is demonstrated to provide greater protection than untreated skin at two exposure intensities of UV:
- 68% protection from intensive UV exposure
- 79% protection from daily UV exposure
Protocol: 10 subjects received an application of Silymarin CF on the back for four consecutive days followed by UV-irradiation with one exposure of 3x MED or three consecutive daily exposures of 1x MED. Measurements of erythema and photography were taken 24 hours after the final exposure.
Study B
Lipid peroxides are the chemical product of oil oxidation—they damage cell membranes and induce inflammation, and can contribute to blemish formation. Silymarin CF was evaluated in-vivo for its ability to protect human sebum against oxidation after four weeks of use, and was shown to be effective at reducing lipid peroxides by up to 76%.
Protocol: Sebum collected from the forehead of 35 subjects in China with oily skin, after 4 weeks of Silymarin CF use. The ratio of squalene to squalene peroxides was measured.
