Korean Skincare Routine for Post-Inflammatory Hyperpigmentation (PIH)- Oily Skin

Routine Overview

Kbeauty Skincare Routine for Post-Inflammatory Hyperpigmentation (PIH)- Oily Skin

This routine is built for oily, breakout-prone skin dealing with post-inflammatory hyperpigmentation. It combines gentle low-pH cleansing, controlled AHA/BHA exfoliation, a concentrated TXA + niacinamide + arbutin serum, lightweight calming moisturizer, and daily high-protection sunscreen to reduce new congestion while supporting gradual fading of existing marks.

What results to expect (realistic):

• 7-14 days: smoother-feeling texture and more balanced-looking skin.
• 3-6 weeks: newer post-acne marks can begin fading and overall tone may look more even.
• 8-12 weeks: stubborn PIH may soften gradually when sunscreen and treatment are used consistently.

   • Helps reduce unnecessary irritation that can make PIH look worse.

2. Toner: [Cosrx] AHA/BHA Clarifying Toner 150ml
