of urban Indians have uneven complexions, regardless of age or gender, largely due to skin pigmentation.

The causes of skin hyperpigmentation are diverse and include factors such as genetics, sun exposure, nutritional deficiencies, and hormonal changes, including those related to pregnancy, thyroid disorders, PCOS, and Addison’s disease. It can also be triggered by medications like oral contraceptives, systemic conditions like dyslipidaemia and impaired glucose tolerance, improper use of over-the-counter or prescribed creams, and a result of skin inflammation or injury, including acne.

Sunscreen, protective clothing, hats and seeking shade wherever possible form the ultimate shield when it comes to prevention of pigmentation.
