Our hyaluronic acid microneedle Roller serum contains hydrolyzed collagen and glycerin. It can stimulate collagen production, improve skin elasticity, reduce wrinkles and sagging. Its application method is very simple: thoroughly clean the skin, dry first, open the lid of the acne treatment serum, install the 64-needle roller head above the serum bottle, roll the roller evenly on the skin surface to spread the microneedles all over the facial skin, and use for 15-20 minutes at a time. And immediately after use, your skin will feel hydrated and plump, fine lines will be reduced, and a healthy glow will emerge.
