Ablative lasers remove the outer layer of skin, which can cause some pain and discomfort. It also makes you more susceptible to the effects of the sun, which is why you must avoid sun exposure for a period of time after treatment. LaseMD, however, is non-ablative. It works from the inside out, so your skin is less vulnerable to the sun and discomfort. This means that you don’t have to avoid sun exposure, nor do you generally require any recovery downtime after treatment.
