Redness is a common risk after laser especially ablative laser/radiofrequency.
We often see redness on fitzpatrick 1-3 skin types after ablative RF or laser. This is also known as post-inflammatory erythema.
Redness happens after almost all laser mole/lump bump removal treatments. It is limited to the area of the treated area ie the diameter of the initial lesion.
It can also happen after full face ablative laser and fractional ablative laser and plasma pen.
It can also happen after RF mole/lump bump or capillary removal. Again, the size of the redness is the size of the area treated. In the case of lump removal , the redness it is approximately the diameter of the initial lump, and for RF capillary removal it is usually extremely minor redness with a diameter of <1mm
Is redness after laser common?
It is very common with ablative laser and would be expected in most cases for patients with fitz 1-2.
It is not as common after IPL, but can occur with low contrast freckle removal at higher settings.
Is the redness temporary or permanent?
The redness after laser or IPL or RF is usually temporary.
In the case of ablative laser, the redness can last many months, but will eventually resolve.
Can Pigmentation happen after laser too?
Yes, pigmentation (PIH) can happen after laser, too, and is more common in Fitzpatrick 3-6 skin tones.
Can Pigmentation and Redness after laser occur together?
Yes, the affected areas can have a combination of redness and pigmentation.
What can I do about PIH and PIE?
The redness will usually resolve without treatment, but patience may be required. Regular LEDs are recommended. Home skincare products and sunscreen are also recommended
PIH can be prevented and treated with anti-pigment topical creams steroids and sunscreen and sun protection is advised,
FAQ
1. Is redness after laser treatment normal?
Yes. Redness—also called post-inflammatory erythema—is a common and expected reaction after laser or radiofrequency treatments, especially ablative ones.
2. How long does redness last after laser?
Redness duration varies by treatment type and skin tone. After ablative laser, it can last for weeks to months but usually resolves over time.
3. Which skin types are most prone to redness?
Fitzpatrick skin types I–III are more likely to experience redness following ablative or fractional laser treatments.
4. Can redness happen after other devices?
Yes. Redness can also occur after RF or plasma pen treatments, usually limited to the size of the treated area.
5. Is redness permanent?
No. Redness following energy-based treatments is typically temporary and fades as the skin heals.
6. Can pigmentation appear after laser too?
Yes, pigmentation (PIH) can develop, particularly in darker skin tones (Fitzpatrick III–VI). Redness and pigmentation may sometimes occur together.
7. How can redness and pigmentation be managed?
Gentle LED therapy, topical skincare, and daily sunscreen use can help support recovery. Your clinician can also recommend suitable at-home products.
8. When should I be concerned?
If redness worsens, becomes painful, or is accompanied by swelling or infection, contact your clinician for assessment and guidance.
