Love this serum! The 10% lactic acid gently exfoliates while the hyaluronic acid helps keep my skin hydrated, so my skin always feels smoother and looks brighter after using it. It’s effective without being overly harsh, and the price makes it an even better value. Definitely a staple in my routine. 💕

Clears up scars beautifully, but its strong!
This stuff is strong. I apply to my face once a week for 5 minutes then rinse off. Leaves my skin smooth, baby soft. Be careful if you use retinoids, could be overkill. I use it on other parts of body that have scars.
