I've hit the jackpot with this SkinCeuticals miracle serum. The CE Ferulic Serum is an antioxidant combination that fights photoaging, builds collagen, and protects again harsh environmental pollutants. What this means to me is extra hydrated skin, an even tone, smaller pores, and a flawless look. I've been using the serum for only a week, and already I can tell a difference in my skin's elasticity and texture. Definitely worth the investment.
