The Lonvitalité Microneedle Derma Roller 0.30mm is an easy-to-use, Titanium 540 Needle Roller made especially for use as an at-home treatment. Suitable for all skin types, it is designed to help rejuvenate the complexion by improving skin tone and texture. The roller works by penetrating the skin's surface with its hundreds of tiny titanium needles and creating micro-channels into the outer dermal layer (middle layer of skin). These channels then assist in increasing the absorption and efficacy of serums and elixirs by up to 40%. Regular use of the roller (2-3 times per week) can help to firm and brighten the complexion, and may also help to diminish the appearance of scars and pigmentation.
