Inner Thigh Hyperpigmentation: Causes & Protocol

​Just completed the deep-dive course on hyperpigmentation. Great information! I was wondering how you address pigment issues in sensitive body areas—specifically, the inner thighs.

​Because this zone is prone to friction, thin skin, and post-inflammatory hyperpigmentation (PIH), aggressive treatments like glycolic acid are a no-go. I use the following approach:

1. ​Gentle Exfoliation: Mandelic or Lactic Acid (skipping Glycolic to prevent irritation).

2. ​Pigment Inhibition: Azelaic Acid to target tyrosinase activity safely.

3. ​Soothing - Brightening: Mild Tranexamic Acid combined with Niacinamide to soothe inflammation and block melanosome transfer.

​Addressing the root cause (friction) is just as vital as the active ingredients!

​How do you usually approach hyperpigmentation in sensitive body zones?
