There are no harmful side effects associated with AviClear laser acne treatments. Minor side effects, such as swelling and redness, typically resolve within a few hours to a few days. Ice packs can help to relieve these discomforts. About half of patients in clinical studies with moderate to severe acne experienced temporary acne flare ups after AviClear treatments. Rarer, temporary side effects included skin dryness, skin texture changes, blistering and hyperpigmentation. All of these side effects resolved on their own, in due time, or with additional post-treatment protocols. The end results were still maintained, despite these side effects. It is important not to pick at scabs and to follow all pre and post-treatment care instructions to avoid side effects. This treatment requires no downtime. You can return to normal activities immediately after treatment sessions. However, you will be advised to avoid heavy exercise or ‘hot’ activities, such as sitting in saunas, for at least a day. You should be diligent to apply sunscreen every 90 minutes during your course of treatment, and thereafter. AviClear is safe for all skin tones. Pregnant women may not undergo AviClear treatments.
