Melasma is a hyperpigmentation abnormality that is generally acquired that affects women in a higher percentage compared to men. This is a condition of multifactorial skin triggered by sun exposure, hormonal changes, systemic diseases, medicines and genetic vulnerabilities. Melasma treatments are traditionally centered on the use of daily sunscreens and topical whitening creams or chemicals.
However, given the broad absorption spectrum of melanin, various lasers and light sources have also been investigated with some success. These studies include the use of the Intense pulsed light (IPL), ablative (ABL) and non-ablative fractional lasers (NAFL), QS 1064 nm, QS 694 nm and picosecond devices.
Also, there is recent evidence to suggest a vascular component to melasma, and, therefore, improvement in melasma has been achieved combining the PDL with other therapies that mainly target hyperpigmentation.

The IPL has a wavelength starting from 515 Nm to 1200 Nm, which is considered useful in the treatment of melasma because it can target epidermal and dermal pigments. Study in 2011 by Goldman et al. Shows a 23% increase when the IPL used itself vs 57% increase when the IPL is used in combination with topical therapy.
Similarly, in 2012, Figuereido et al. show a 49.4% increase using IPL in a topical combination, with sustainable
44.9% increase in 12 months follow-up. Interestingly, in 2008, Li et al. Reported 51% increase with four consecutive IPL sessions. In their study, it was mainly highlighted in patients with a dominated epidermal meloprand which has a type of FitzPatrick I-III skin, which is important to consider when applying it to clinical practice.
