A BBL treatment is non-invasive and non-ablative. There is typically only mild redness and heat that can persist for several hours post treatment but no bruising or swelling. This means this patient can return to their normal routine right after the procedure without having to worry about downtime. Avoiding active ingredients like glycolic, salicylic or lactic acid and retinol before and after treatment for 72 hours is critical to keep the skin safe. Minimizing sun exposure before and after treatment is also important along with sunscreen of SPF 30 or higher.
