Photo-bio-modulation consists of treatments where a photosensitive gel is applied to the area to be treated, this is illuminated with a low-power LED light of different wavelengths. They are non-invasive, painless, non-systemic treatments, they do not cause cell destruction and do not eliminate the skin’s natural barriers. The gel used during the treatment does not absorb into the skin, therefore, these treatments can be used all year round, including summer.
