Everyone’s skin reacts differently to laser treatments, however, here are some general
guidelines as to what to expect after treatment. When receiving treatments for laser
hair removal, treated skin may react with redness and swelling. Some people may
experience itching over the treated area as well. These reactions usually go away
within 2-4 hours, with the possibility of lasting a day or two or even a week in
some cases.
When receiving treatment for sun spots, the pigmented areas will appear darker immediately
after treatment and then crust over within a few days. Care should be taken to keep
the area moisturized, protected with sunscreen, and undisturbed. The crusted area
will eventually fall off on its own to reveal skin that may be lighter than your
skin tone. Your skin will even itself out over the next few weeks after treatment.
After vein treatments, the treated area can react with redness, swelling, and bruising
that can last up to three weeks. As the bruising fades, the vein will also fade
gradually for 4-8 weeks after the treatment.
