The vitalize peel has be reported to improve melasma. However, like all treatments for melasma, it is not a one time treatment or a permanent solution. Melasma is multifactorial - ultraviolet light, heat, inflammation, and estrogen all play a role. That also means it is very likely to recur whatever the treatment. So before you commit to a series of peels, be sure you are also committed to vigilant sun protection all year round with physical sunscreen ingredients and sun avoidance plus a protective hat with a wide brim when you know you will be exposed. Other helpful additions are oral antioxidants like that found in Heliocare which has been shown to reduce the inflammatory and oxidative effects of UVA and regular use of a retinoid and anti-pigment ingredients (vinoferine, vit C, arbutin, soy, licorice among others) and as needed use of a prescription hydroquinone.I hope this answer was helpful.Wishing you the best of luck.
