FDA approved SkinPen microneedling treatment. The face is washed, a numbing agent is applied, and the skin is cleaned with an antiseptic before treatment. The SkinPen uses 14 microneedles to stimulate collagen by repeatedly puncturing the skin. It may improve wrinkles, stretch marks, scars, acne scarring, skin tone, fine lines, loose skin, large pores, discoloration, and thinning hair. The treatment requires 3 to 4 treatments spaced 4 weeks apart.
