I wanted to share with you all a serum I have been using to treat my breakouts. It is the Niacinamide Youth Serum by Dermaquest. A little about my skin, I have combination skin with occasional acne flares. Regardless of the amount of water I consume, my skin is dry from using acne treatments. I cannot use a thick moisturizer to fix that because excess oils only make matters worse for me. Due to this history, I was excited at the chance to give this serum a try, knowing the quality of Dermaquest products.
