Post-Acne Red Marks vs Brown Spots: Treatment Differences

After acne clears, many people are left with red or brown marks that are not true scars. They are flat and often fade over time, but treatment can speed things up. The right approach depends on the colour.

1. Red marks (PIE)

Post-inflammatory erythema (PIE) appears as red or pink marks where acne was. It is caused by dilated or damaged blood vessels and is more noticeable on fair skin.

2. Brown marks (PIH)

Post-inflammatory hyperpigmentation (PIH) appears as brown or dark marks caused by excess melanin after inflammation. It is more common in Asian and darker skin types.

3. Treating red marks

Vascular lasers target blood vessels.

Calming skincare and barrier support.

Exosome to reduce redness.

Strict sun protection.

4. Treating brown marks

Pico laser and laser toning to break down pigment.

Brightening skincare as advised.

Tranexamic acid in some cases.

Strict sun protection.

5. Timeline

Without treatment, marks can last months. With treatment, many improve over a few sessions. Brown marks may need more sessions in darker skin.

6. Preventing new marks

Treat active acne early, avoid picking, and use sunscreen daily.

7. Cost

At MIN Clinic, pico laser typically costs KRW 200,000 to KRW 600,000 per session, and exosome KRW 400,000 to KRW 900,000. See our event price list.

Conclusion

Red marks need treatments targeting blood vessels and redness, while brown marks need pigment-focused lasers. Send photos to our English-speaking team on WhatsApp, or explore our pico laser page.
