Normally your skin will look a little pink or reddish immediately afterwards for 10-30 minutes or so. If your hair growth is very coarse and dense, you may remain somewhat red until the next day. It is usually less disruptive than waxing.
Very occasionally, if the hair is extremely deep or coarse, some of the follicles may become inflamed for a few days. Cool with a damp cloth if needed and avoid a hot wash. You may apply anti-inflammatory medication such as cortisone or use a salyclic acid cleanser. More commonly, laser is beneficial for acne or pimples, or in-grown hairs.
You should stay out of the sun for a few days or as long as any visible signs of irritation remains. As discussed under “concerns”, if your skin is dark or susceptible to hyper pigmentation, you should be vigilant and take all precautions.
Your hair may begin to shed (fall out) a few days after your treatment. It will continue to grow slightly as it sheds. You may not notice this shedding process unless you pay close attention. You may continue to shave or use a depilatory cream, but do not remove otherwise. About 1 – 3 weeks after your treatment your hair will be finished shedding.
Although the majority of your hair should shed, this is not the amount that will stay away. You will notice the surviving hair returning in about 6 -12 weeks at which time another treatment is needed. If there is still very little hair showing at 12 weeks, then you should wait a few more weeks to allow for slow growth. At this point if the hair growth is clearly reduced, that would indicate a good response. Reduction becomes more apparent with each treatment.
