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 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 inital lump, and for RF capillary removal it is usually extremely minor redness with a diameter of <1mm
Is it 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 occur together after laser?
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,
