Erythema (redness), swelling and occasionally pain develop immediately after laser hair removal and may last from several days to weeks. Cool compresses, gel packs and ice packs typically help reduce these effects. Over-the-counter pain medications can also be used to relieve pain. Topical corticosteroids may be used for the first day or two following treatment to reduce the development of other adverse effects and topical emollients may be used to maintain skin moisture.

Hair will be shed from the targeted area in the first couple of weeks. Epidermal injury (e.g., blistering, crusting) is rare but may occur. Saline (salt) soaks and topical antibiotics may be used to treat such injury.

The patient can return to normal activities immediately, but avoidance of direct sun exposure is generally recommended for at least a week and a sunscreen with a high sun protection factor (SPF) needs to be applied regularly.
