I have been using this product for about 6 months and I loved every second of it. This is my first ever retinol product, and it set the bar for retinol serums high for me. It does not dries my skin, or make it feel stretched, instead my skin feels plumped and looks glowing after using it. Of course after applying it I wait for around 10 minutes before applying the next product (in my case, it's the moisturizer). This helps a lot with my acne and breakout, uneven skin tone, and dark spots from acne scar. I tried another retinol serum and I was traumatized bcs of my own stunt. I experience a very bad breakout that not only my skin was struggling, my self-confidence was also struggling bcs I wasn't comfortable with my own skin. Then I used this product again, and again it saves my skin and myself from that dark times. Definitely my first love with retinol and also the door that opens the world of skin care to me. This is my opinion about this product based on MY EXPERIENCE.
