IPL is effectively trying to destroy the blood vessel that feeds the hair papillae, by using controlled heat and light sources, thus resulting in hair reduction. Usually a series of treatments is required to achieve long lasting results – this is usually a minimum of 4-6 and possibly up to 8-10 treatments.
When the light is emitted from the hand piece, it tries to detect a dark chromophore below the surface, in this case a hair shaft. For this reason, IPL is only suitable for dark hair, as it cannot detect a chromophore in white or grey hair. Ideally, fair skin is better to treat, as the light by-passes the chromophore in dark skin (melanin) and goes straight to the hair papillae. However, at laser express we use hand pieces suitable for dark, tanned even black skin. For this reason it is important to know what equipment your operator is using.
