Abstract
BACKGROUND: Lasers and intense pulsed light sources (IPLS) are proposed for the treatment of many pigmentary disorders. They are sometimes considered as magic tools able to remove any type of lesions. Although being the best option for several hyperpigmented lesions, they can also worsen some conditions and have potential side-effects. OBJECTIVE: The aim of this review was to give evidence-based recommendations for the use of lasers and IPLS in the treatment of hyperpigmented lesions. METHODS: These recommendations were produced for the European Society of Laser Dermatology by a consensus panel made up of experts in the field of pigment laser surgery. Recommendations on the use of lasers and light treatments were made based on the quality of evidence for efficacy, safety, tolerability, cosmetic outcome, patient satisfaction/preference and, where appropriate, on the experts' opinion. RESULTS: Lasers and IPLS are very effective for treating many hyperpigmented lesions such as lentigos, dermal hypermelanocytosis or heavy metal depositions. In the other hand, they have to be considered with great caution for other disorders, such as café au lait macules, melasma or postinflammatory hyperpigmentation. After making the correct diagnosis, if lasers or IPLS are indicated, the optimal wavelengths and parameters will be chosen taking into account the skin phototype, origin and depth of the target pigments. CONCLUSION: Although potentially very effective, lasers and IPLS cannot be proposed for all types of hyperpigmented lesions. In all cases, precise recognition of the disorder is mandatory for choosing between these devices and other therapeutic approaches.
