I went online to by Skinceuticals C + E Ferulic acid and found another brand: Cosmetic Skin Solutions C + E Ferulic Combination Antioxidant. The ingredients are the same and I read online user reviews that claimed the same results. The big difference is the cost - ~ $50 (or on sale for $40).

Has anyone here tried this product? I'd be curious what Dr. Baumann knows about this.
