The core principle of micro-needling is to stimulate the production of new collagen by needling the skin. Taking advantage of the skin's ability to heal itself, micro-needling causes micro-injuries to the epidermis, which signals the body to produce new collagen and elastin to rejuvenate the damaged area, effectively rejuvenating the skin and making it look younger.

The Medical Rejulight rejuvenates the skin by using monochromatic light rays produced by RVD LEDs. These light rays have a restorative effect on skin conditions, including skin ageing, acne, psoriasis, stretch marks and scars.
