Derma Rollers are small handheld devices used in skincare routines, classified under beauty tools. They feature tiny, fine needles that create micro-injuries on the skin's surface, stimulating collagen production and aiding in product absorption. This process rejuvenates the skin, minimizing the appearance of wrinkles, fine lines, scars, and hyperpigmentation. Derma Rollers fall under the umbrella term of beauty brushes or tools due to their role in skincare enhancement. They are specifically designed for at-home use, offering a non-invasive alternative to professional treatments like micro-needling or dermabrasion.
