Dermarollers / Facial rollers with Microneedle treatment that renews, improves but at the same time preserves the skin's natural structure! When you use a facial roller, you let the microneedles gently break down the outer layer of your skin by creating small holes with the needles. After an hour or so, these holes from the microneedles will begin to heal. Just during this hour when the skin is healing, your absorption of softening creams, oil and serum increases, which makes a Dermaroller a great aid in connection with other skin care products! It may sting a little during use at first but usually does not hurt at all and is harmless to use on the skin. Feel free to use together with other skin care products for better effect!
