What should you know about exfoliating dark inner thighs?

Repeated rubbing, tight clothing, sweat, or a rash can irritate the fold and leave extra pigment after the irritation settles. Intertrigo is one possible cause, especially when there is redness, moisture, soreness, or an odour. Shaving and waxing can also cause small areas of inflammation that darken as they heal. Dark colour alone does not show which cause is responsible.

Wash with lukewarm water and a mild, fragrance-free cleanser, then pat dry rather than rubbing. Apply a plain moisturiser to support the skin barrier. Reduce rubbing with breathable clothing and a well-fitting layer between the thighs. Do not use rough gloves, lemon, baking soda, or strong acids on the fold. Stop exfoliation if stinging, burning, scaling, or redness appears. A clinician can assess the cause and discuss options such as a Chemical Peel, Laser Toning, or Laser Hair Removal when appropriate.

Arrange a skin assessment if the area is painful, persistently itchy, cracked, oozing, rapidly changing, or repeatedly inflamed. Seek prompt care for spreading warmth, marked swelling, pus, or fever. A clinician can distinguish pigment left by irritation from an active rash or another skin condition.

Could friction, intertrigo, hair removal, or another rash explain the colour? Which products should I stop? Would a procedure suit this skin fold, and how would irritation be prevented?
