I used the 15% OBAGI Professional-C Serum for six weeks. From the first week, my skin felt smoother and looked more radiant. By week 3, the texture visibly improved, and my dark spots started to fade.
It layered beautifully with my other products, especially my sunscreen and moisturizer. It absorbed quickly without leaving a sticky or greasy finish.

This vitamin C serum gave me a healthier, glowing complexion without irritation.
