The SkinPen uses tiny needles to create microinjury to the skin which promotes collagen production, leading to firmer, smoother, and softer skin. Collagen is a protein that helps to keep the skin looking youthful. An increase in collagen production reduces fine lines and wrinkles, acne scaring, age spots, skin pigmentation issues, and pore size. Treatments typically cause redness and mild swelling for 24-48 hours. Although some results may be immediate, most clients see noticeable results 4-6 weeks post treatment. Treatments should be scheduled every 4-6 weeks until desired results are achieved. A minimum of 3 treatments is recommended.
