Keep the area clean and dry, wear loose cotton underwear, and avoid friction. You can apply a gentle moisturiser or aloe vera gel to help the skin heal naturally. If you want to lighten the marks faster, your doctor may suggest a mild depigmenting cream, but use it only under medical advice, as the genital area is very sensitive. If spots change in colour, size, or return with itching, see a dermatologist or urologist for a proper check-up.
