DERMATOLOGIST APPROVED👨‍⚕️⁠ ⁠ According to Dr. Shah @dermdoctor: “Vitamin C is an antioxidant that boosts collagen and fights hyperpigmentation. But the active form isn’t very stable and has trouble penetrating the skin. You want to look for a stabilized form between 8-20% like this one from BeautyStat. I also like that this one has the additional antioxidant benefits of green tea.”⁠ ⁠ Check out the Universal C Skin Refiner to see incredible results in as little as 4 weeks!
