I have used this for a decade and still love it. I started with the 5%, skipped the 15% as it was no stronger than the the 5%, and quickly built up to the 20%. I even use around my eyes and on my eyelids. Great daily exfoliant and makes your skin glow
Best product ever .....
Love this product was suggested by my dermatologist have been using couple of years.
I have been using Obagi Vit C 20% for several years every morning. My dermatologist says my skin is amazing for being 78 yrs old.
Love the obagi c serum. Noticed a difference within a few days. Of all the countless skin products I have wasted money on, this will definitely be part if my everyday skincare.
