So far, not getting the results I had hoped for. I am concerned about my dark spots and discoloration. My skin does feel soft and pores are smaller.

Amazing products - highly recommend!

I just turned 30 reached out to Dr. Koo, worried about early fine lines/wrinkles and the firmness of my skin deteriorating. I started on both products, and my skin has never felt or looked better - coloring, firmness, hydration have all improved.

Both products go on feeling like a whipped, silky, hydrating serum -- I don't like the feeling of wearing product, so I was initially worried about this -- but they quickly absorb into the skin. Now I look forward to the 2 minutes of silkiness on my skin each day :D
