Micro-needling is process carried out with a roller that is covered with numerous tiny needles. These needles penetrate the upper layers of skin to a depth of up to 1,5mm (depending on the needle length used). This process has two major benefits. It effectively stimulates collagen formation at the same time as providing a clear channel for topical gels and creams to be absorbed more effectively through the top layer (epidermis) of skin. In order to achieve the maximum effect, it is recommended to perform a series of at least 3 treatments at intervals of 2 weeks.
