Side effects with Cosmelan treatments are rare but easily managed. Some skins may feel a little red following removal of the in-clinic mask. This may be accompanied by some minor dryness and flaking. Any tightness may be easily relieved by applying a nurturing moisturiser such as Hydra-Vital Factor K.

It is recommended to avoid direct sun exposure following a Cosmelan treatment and to wear a broadspectrum SPF30 every day before, during and following treatment.
