If the thought of micro-needling scares you, the ORA Gold Deluxe Microneedle Derma Roller System 0.25mm with Black Head & Silver Handle is a gentle painless at-home microneedle roller that can be used on the face, body, and scalp. Microneedle therapy has been used for decades by dermatologists, estheticians, and Hollywood celebrities, and with a roller head with 540 0.25mm needles, the ORA derma roller promotes collagen and elastin production to reveal younger-looking, smoother skin. With regular use, this roller helps reduce the appearance of scars from injury or acne, fine lines, wrinkles, and stretch marks as well as smooth uneven skin texture and color, and heavy pitted skin. When used on the scalp, the roller helps stimulate and maintain hair within thinning and balding hair areas.
