In a tropical country like India, the skin tone of people range from fair to dark brown, and all shades in between. The darker skin types have a higher tendency to tan from excessive sun exposure. The tanning often develops quickly but takes many months to fade away, thus people opt for anti-tan treatments.
Multiple factors like friction, vitamin deficiency, micro-injury, acne, etc. can also lead to hyperpigmentation. Thus, skin lightening treatments are a boon for individuals who desire clarity in complexion and even-toned skin.
