Unfortunately for the scope of this article and giving you more personal information, this will depend entirely on the amount of skin that you need to have treated, as well as the procedure that you choose. Microdermabrasion can often be performed during a lunch break, and then the patient can return to work without any problem. The only effect will often be a slight amount of local irritation and redness, although it is important to note that multiple treatments may be required for the full effect.
Chemical peels and laser resurfacing are often more involved. The chemical peeling process will induce a small scab over the treated area, which can then be removed with gentle soap and water washes. The skin will heal over the next 6-7 days, and then there will be some notable redness for another variable amount of time as your skin heals. The laser treatments will generally have some redness for up to 4 months, during which time the patient should take care to avoid sun exposure.
There are many resources available online, and your doctor's office will be more than happy to discuss all of these in detail with you prior to pursuing any one option.
