The dermaroller must be disinfected before and after use, the alcohol rinsed off with water and stored in the container provided after cleaning. It is recommended to use it every 3-4 weeks. For experienced users or those who prefer treatments on shallow scar areas or stretch marks, needles of 1.0 to 1.5 mm are the most effective choice. Microneedling can quickly open tiny channels in the skin that effectively deliver nutrients to the skin, activate the body's natural healing process and produce collagen, which is essential for hair growth. These microscopic channels also contribute to better absorption of skin and beard growth products. 1.0mm DermaRoller for hair and scalp against hair loss and 1.5mm Dermaroller for the treatment of scars, acne on arms, back and décolleté. Our needle roller has helped to shrink pores, clear acne, prevent wrinkles, stretch marks and breakouts and minimise the appearance of acne scars - leaving skin healthier and more radiant.
