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

This routine is built specifically for oily, breakout-prone skin dealing with PIH (post-acne marks). PIH fades faster when you do two things at the same time: (1) prevent new inflammation (clogging and breakouts), and (2) consistently block UV (because UV keeps pigment “switched on”). The routine uses a pore-unclogging but barrier-friendly cleanser, a gentle AHA/BHA toner to smooth and prevent clogged pores, a targeted TXA + niacinamide serum to fade marks, a lightweight calming gel-cream to keep skin stable, and a matte-leaning sunscreen so results actually stick.

What results to expect (realistic):

• 7-14 days: fewer “angry” flare-ups, less mid-day shine, smoother texture.
• 3-6 weeks: newer post-acne marks start fading; tone looks more even.
• 8-12 weeks: stubborn PIH softens noticeably (daily sunscreen is the deciding factor).

The 5 Products (Luxiface catalogue)

1. Cleanser: [Anua] Heartleaf Succinic Moisture Cleansing Foam 150ml

   Why it belongs for oily PIH: PIH keeps happening when clogged pores and inflammation keep happening. This cleanser is built for acne-prone skin with ingredients aimed at unclogging and regulating oil while staying pH-balanced and barrier-considerate.

   Benefits in this routine:

   • Helps unclog pores and regulate excess sebum (important for preventing new marks).
   • Removes dead skin buildup gently so tone-correcting steps work more evenly.
   • Barrier-supporting feel helps reduce irritation that can worsen pigmentation.

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

   Why it fits PIH + oily skin: PIH fades faster when texture is smooth and pores stay clear. A mild AHA/BHA toner helps prevent clogged pores, gently refines the surface, and supports brighter-looking tone without heavy layers.

   Benefits in this routine:

   • Gentle exfoliation helps improve the look of post-acne marks over time.
   • Helps keep pores clearer, reducing the chance of fresh breakouts (and fresh PIH).
   • Preps skin so the serum spreads evenly and performs more consistently.

   Smart use for oily skin: Start every other night for 1 week, then increase to nightly if comfortable. If you feel stinging or dryness, reduce frequency.

3. Treatment Serum: [Anua] Niacinamide 10% + TXA 4% Serum 30ml

   Why this is your PIH “workhorse”: TXA + niacinamide is a strong combo for uneven tone and dark marks, and it stays lightweight enough for oily skin. Niacinamide also supports oil balance, which indirectly reduces new breakouts and new marks.

   Benefits in this routine:

   • Targets PIH and dark spots directly for a clearer, more even tone.
   • Light texture that layers well under gel moisturizers and sunscreen.
   • Supports skin resilience so you can stay consistent (consistency fades PIH).

   How to start: Use once daily for 5-7 days, then move to AM + PM if your skin stays calm.

4. Moisturizer: [Dr.G] Red Blemish Clear Soothing Cream 70ml

   Why oily skin still needs this: Over-drying oily skin usually backfires (more oil, more inflammation, more marks). This gel-cream calms and hydrates without heaviness, helping you tolerate the toner and serum with less irritation.

   Benefits in this routine:

   • Quick-absorbing gel texture hydrates without stickiness.
   • Soothing support helps reduce the “inflammation cycle” that deepens PIH.
   • Helps keep the barrier stable, which improves long-term fading results.

5. Sunscreen (AM only): [CellFusionC] Advanced Clear Sunscreen 100 SPF50+/PA++++ 50ml

   Why this is non-negotiable for PIH: UV re-darkens PIH and slows fading. This sunscreen is a strong match for oily skin because it aims for a refreshing matte finish and a low pore-clogging feel, which makes daily use easier.

   Benefits in this routine:

   • High UV protection prevents PIH from deepening and returning.
   • Matte-leaning finish supports oil control and comfortable daily wear.
   • Helps protect the results you earn from the serum and toner.

AM Routine

How to Use- (Steps 1 to 5)

1. Cleanser: Cleanse for 30-45 seconds with lukewarm water, focusing on the T-zone. Rinse well.
2. Toner: Apply a light layer. If you are new to acids, use it only 3-4 mornings per week for the first 2 weeks.
3. Serum: Apply 2-3 drops over the face, then tap a tiny extra amount onto post-acne marks.
4. Moisturizer: Apply a thin layer (lighter on the T-zone, normal on cheeks).
5. Sunscreen: Apply generously to face and neck. Reapply every 2-3 hours if outdoors or in strong daylight near windows.

PM Routine

How to Use- (Steps 1 to 5)

1. Cleanser: Cleanse thoroughly. If you wore heavy sunscreen, cleanse a little longer (still gently).
2. Toner: Use the COSRX toner 3-4 nights/week for week 1-2, then increase as tolerated. Do not scrub or rub it in.
3. Serum: Apply an even layer. For stubborn PIH, add 1 extra drop and press it into the darkest marks.
4. Moisturizer: Seal with a thin layer to prevent dehydration (dehydration can trigger more oil).
5. PIH success rule: If you feel irritation or peeling, skip the toner for 2-3 nights and continue only cleanser + serum + moisturizer. Consistency beats intensity.
