Why Must I Avoid The Sun While Having Laser Treatments?

The laser targets the melanin (color) in the hair shaft. Increased melanin (color) in the skin will compete for the laser energy intended for the hair follicle beneath the skin.
The presence of a tan can lead to discoloration of the skin and blistering.
Recent exposure to the sun, or tanning beds, stimulates melanocytes increasing the risk of hyperpigmentation (increased color) in the shape of the laser gauge.
Adding sun exposure (or extreme heat) sooner than 1 week following your treatment may also lead to adverse reactions.
Hyperpigmentation is not permanent, but may take anywhere from a few weeks to a year or more to resolve.
The pigment from spray tans or lotions will also compete for the laser energy; however, these are perfectly safe “following” your laser treatment.
