Avoid harsh scrubbing, waxing, and fragranced products on the area
Use a gentle, fragrance-free cleanser
Keep the area dry and reduce friction with loose, breathable clothing
Exfoliate lightly and infrequently with a mild product if tolerated
Apply a moisturizer with ingredients like niacinamide, azelaic acid, or licorice extract on external skin only
Consider over-the-counter brightening products made for sensitive skin
Use sunscreen on exposed skin around the area
Stop products that cause burning, itching, or irritation
Shave carefully or switch to gentler hair-removal methods to reduce darkening from irritation
See a dermatologist for prescription options such as hydroquinone, tretinoin, or other treatments
Get medical advice if darkening is sudden, severe, or associated with itching, pain, rash, or thickened skin
