You can shave immediately or you can wait it’s really up to you. There’s no reason you can’t shave, just the face is a bit more sensitive than other areas of the body so I usually find for 1 or 2 days after treatment my face is slightly irritated feeling so I don’t want to shave. It doesn’t look like it is, just feels a bit tender. I had beard done exactly 11 days ago, I shaved the next day then again a couple days after that. It’s perfectly fine to shave, but the big thing I find is that the hair looks and reacts differently. No matter how close you shave, it looks almost like you have stubble still or a 5 o’clock shadow.
It can also depend on how you react to the treatment. For example sometimes I break out in white heads right after which I think is from the type of numbing cream used, since it’s so greasy all over my face, covered with saran wrap for 30 minutes, then followed by ultrasound gel, followed by the laser, followed by moisturizer and SPF. That usually lasts a few days and I don’t like to shave when I have that, but I’ve only had that maybe 3 times of out 7+ treatments.
My suggestion is shave as soon after as you feel comfortable doing. If your face is sore and irritated then obviously don’t since it will probably make you break out or whatever, but if you’re able to then go for it. Then around day 6 or 7, stop shaving if you can. The hair will all start to fall out around day 10-11. The longer it is the better, because you can use a sugar scrub or loofa for example and it will easily fall out. If you keep shaving though then it’s harder for it to just fall out on it’s own since there’s nothing visible on the surface for it to rub against and slide out. It’s perfectly fine though to keep shaving, it just takes a bit longer to all fall out. You shouldn’t look patchy though unless your clinic missed areas of your face. All the hair will generally fall out around the same time.
That’s followed by the best part, 1-2 months of a hair free face!
