Lasers and the sun do not mix.  The reason is because the laser’s function is to destroy freckles, brown spots, blood vessels, and tattoo pigment. If the surrounding skin is also tan, the laser mistakes it for “one big brown spot”. However, certain lasers can be adjusted for patients with darker toned skin.  After laser skin care treatments, it is usually recommended to avoid sun exposure for at least 7-10 days.  This will reduce the chance of unwanted side effects.
