Hello, Welcome to healthcare magic. The pigmentation you are having may be due to melasma. Melalite XL contains a steroid as one of the components, which on prolonged use can cause redness, skin thinning and whitish discolouration. It has to be used only under the guidance of a dermatologist for not more than 4-6 weeks at bedtime. Safer options would be to use lightening creams containing 2-4% kojic acid , arbutin, liquorice and niacinamide. Also use a broad spectrum sunscreen with SPF 30 every 4 hours even while indoors or in cloudy weather. You could also opt for chemical peels like glycolic peels by a qualified dermatologist. Hope this helps you. Take care.
