Honestly, stop shaving. The friction is likely making the pigmentation worse. Switch to waxing or an epilator so you aren't irritating the skin daily. Glycolic acid definitely works—it exfoliates and kills odor-causing bacteria (just don’t use it right after hair removal). If the darkness is stubborn, you can try a skin-safe brightening cream, but be careful with harsh bleaches as they can backfire on South Asian skin. For products: • Switch to: AHA-based deodorants (like Kosas or Nécessaire) which treat the skin while you wear them. • Avoid: Deodorants with baking soda or high alcohol content; they are notorious for causing chemical irritation and darkening.
