At first, I use it alone with no other serums I noticed my skin looks tired. Maybe it's not used to it yet so I stopped using it for a week to heal my skin. After that I bought 2 other serums with moisturizing and soothing ingredients to use along with this serum. And BOOM, my skin looks healthier, plump, brighter than before; my dark spots because of acne scars and some freckles on my cheeks had gone too. This product is not pure retinol but it's much more affordable than Obagi and Paula's choice. I will repurchase this
