The Silymarin CF serum is a high potency combination antioxidant with silymarin, 15% L-Ascorbic acid and 0.5 % Ferulic acid. I used the serum in the morning after cleansing my face. I applied a few drops to my face, neck and upper chest area. I found the serum to absorb well into my skin, I like the lightweight formula . After using for nearly a week, I have noticed my face looks and feels much more smoother. My skin texture has improved, and the overall appearance looks much better. The only issue I had was I didn't like the scent. The serum smells almost very chemically . This was quite off putting for me
