Ablative Non-fractional Laser

Compare To Other Treatments

The charts below show the chances of developing various side effects from ablative non-fractional lasers.3,5,9-13 For some side effects, we currently do not have enough data to provide a percentage.

Certain/Likely Side Effects (% = Incidence)

SHORT TERM Skin redness (erythema)*up to 100%
SHORT TERM Crustingup to 100%
SHORT TERM Itching (pruritus)up to 57%
SHORT TERM Skin darkening (hyperpigmentation)**18% to 45.5%
SHORT TERM Mild to moderate acne flare-up9% to 32%
SHORT TERM Infectionup to 20%

*Skin redness (erythema): Skin redness is a typical reaction to ablative non-fractional laser treatment. After Er:YAG non-fractional laser treatment, skin redness lasts 1 month on average and normally disappears completely in 3 months. After CO2 non-fractional laser treatment, skin redness may last from 6 weeks to 3 months.5,9,11

**Skin darkening (post-inflammatory hyperpigmentation): Skin darkening may occur in all skin types but is more common in patients with darker skin. It may begin 3-4 weeks after laser treatment and may persist for up to 3 months.5

Possible/Rare Side Effects

LONG TERM Clogged sweat glands (milia)12% fo 14%
SHORT TERM or LONG TERM Prolonged skin redness (erythema)*4% to 9.1%
SHORT TERM or LONG TERM Skin lightening (hypopigmentation)4% to 8%
SHORT TERM or LONG TERM Persistent skin darkening (hyperpigmentation)**up to 4.5%
SHORT TERM or LONG TERM Raised (keloid) scars†incidence not known

*Prolonged skin redness (erythema): Prolonged skin redness is defined as redness that lasts over 3 months.3,11,13

**Persistent skin darkening (hyperpigmentation): Persistent skin darkening is defined as skin darkening that lasts over 3 months.11

†Raised (keloid) scars: The likelihood of developing raised scars may depend on the specific laser settings. Patients with a history of keloid scarring are more likely to develop keloid scars as a side effect of ablative non-fractional laser treatment.3
