This is Best serum ever !
I love this vitamin c. Great quality. I started with 15% because I have sensitive skin but think I can honestly move to 20% with my next bottle.
Obagi makes quality products, and this vitamin C serum is a great way to introduce your skin to medical grade skincare. Vitamin C fights signs of aging, and Obagi's serum can be used both morning and night. During my routine, I use it after cleanser and toner, before applying moisturizer and sunscreen. It's gentle and good for sensitive and acne prone skin. I have noticed a clearer complexion after using it both in summer and winter months.
I got this for my brother who is 25 and just starting to take care of his skin. I am older and use the 20% but was told that 10% was a great starting point. He loves it so far and it already seeing a difference with his melasma.
I've purchased this Vitamin C over and over. It's so hydrating that sometimes I forget to put on moisturizer after - and I have VERY dry skin.
