I tried the SkinCeuticals H.A. Intensifier serum sample, which is meant to make your skin look plumper and smoother. I noticed my skin feels more hydrated and looks better since I started using it. The regimen suggests using it with their C E Ferulic antioxidant in the morning and their sunscreen. To really see long-term changes, I’ll need to buy the full-size bottle. #Unboxing
