I love this serum. I buy expensive products all the time and don’t see any change. This is My second purchase bc I did. See very fast improvement in my skin. I noticed my skin becoming more even toned and less blotchy. Crazy how I noticed changes after a few days of using. I actually ran out and noticed my skin was getting worse so I can’t wait to see it improve again. My only complaint is that it is so runny like water and if u accidentally knock the bottle bye bye. Lucky it’s very affordable. I find it lasts longer if you put the applicator to your face let the drops roll on your skin and rub in rather than in your hands first.
