Q-Switched Laser Side Effects
Q-switched lasers can cause skin to become blistered and crusty. A common post-procedure concern in darker skinned patients is skin discoloration.
Who shouldn't use it: Q-switched lasers should not be used on patients with active cold sores. People who take Accutane should not undergo laser therapy.
The Q-switched ruby laser should not be used on anyone who is not very fair-skinned (Fitzpatrick type I or II).
Drawbacks: Q-switched lasers can alter skin pigment, resulting in hypopigmentation and skin whitening.
Recovery Time For Q-Switched Laser
Even though your skin may look red and crusty for up to two weeks, there is no downtime after treatment that will keep you from returning to work or heading outdoors.
After care for Q-switched laser: Apply topical antibiotics (provided by your dermatologist) and fragrance-free moisturizers for one to two weeks after Q-switched laser treatment. This may help decrease the chances of scarring.
