Description
Silymarin CF is a breakthrough vitamin C serum for oily and blemish-prone skin that combines 0.5% silymarin (milk thistle extract), 15% l-ascorbic acid, 0.5% ferulic acid and 0.5% salicylic acid to help reduce excess oil and visible signs of aging. This oil-free formula reduces oiliness, refines skin texture, and visibly improves skin texture and fine lines.
This combination antioxidant serum is formulated under the Duke Antioxidant patent. Vitamin C is a highly-potent antioxidant that by its structure has difficultly being effectively absorbed by skin. The Duke Antioxidant patent outlines the formulation parameters required for effective delivery of vitamin C to skin:
- Pure l-ascorbic acid (vitamin C)
- An acidic pH within the 2.0-3.5 pH range
- A concentration between 10%-20%
Directions
After cleansing and toning, apply 4-5 drops to a dry face, neck and chest. Gently press into skin. Follow with other skincare products and sunscreen.
