Discover our beauty secrets and feel comfortable and beautiful in your skin. - Unlike the competition, we only use genuine needles made of rust-proof surgical stainless steel. The needle head is set with exactly 192 needles. We have deliberately chosen against a metal handle, as the pressure on the skin can be better regulated by a lower weight of the derma roller. The job of all our products is to give you an all around comfortable and beautiful skin feeling, so we give you this promise: if you don't love them, we buy them back - no questions asked. How to use: sterilise the derma roller with 70% alcohol beforehand and let it air dry. Then clean the face thoroughly. Then apply the desired serum to the entire face. Roll over the face with the derma roller 4-6 times in each direction. Rinse the derma roller thoroughly with warm water and sterilise it again. Finally, apply a moisturiser (without irritating ingredients such as perfume).
