Bleaching lightens the skin and reduces dark spots by reducing melanin levels. It costs around Rs. 250 in India. The benefits of bleaching include clearer skin with fewer dark spots, a lighter skin tone, and reduced tan and dullness. Some precautions for bleaching include not overdoing the duration or frequency, avoiding it if pregnant or the skin feels burned, and not bleaching after hot water baths. Sensitive skin may risk burns from bleaching.
