Derma rolling is a natural process of skin rejuvenation and skin healing, which stimulates the natural production of collagen in the skin. As skin ages, it loses the ability to produce elastin and collagen, which helps the skin look young and fresh, as effectively. Ageing skin doesn’t hold moisture as well as younger skin, and as a result can start to sag and wrinkle. A derma roller is a collagen induction therapy, which uses micro-needling to puncture the dermis (skin’s outer later), with tiny, precise needles mounted on a roller. Opening the skin’s pores temporarily is treated as damage by the body, which works to regenerate it, triggering the production of collagen and elastin. Alongside rejuvenating ageing skin, derma rollers can also be used to treat acne scars, uneven skin tone, post pregnancy stretch marks, skin pigmentation and sun spots.
