The Collagen P.I.N. Microneedling system is the perfect treatment for fine lines and wrinkles, sun damage, brown pigmentation, acne scars, stretch marks, scars, and hair loss. The device induces a controlled injury into the skin’s dermal and epidermal junction which stimulates the production of growth factors, new collagen and elastin. Your result is healthier, younger-looking skin. Depending on the degree of correction needed, 3-6 treatments are recommended, at monthly intervals.
