Light-based treatments, such as blue light therapy and photodynamic therapy, are becoming increasingly popular for acne. These treatments work by targeting the bacteria that contribute to acne. Blue light, for instance, activates compounds in the bacteria, causing them to self-destruct. It's like using a specialized spotlight to zap away acne-causing bacteria. These treatments can be especially helpful for people who can't use certain medications or who haven't responded well to other treatments.

Chemical peels involve applying a solution to the skin that causes the top layer to peel off. This can help unclog pores, reduce oil production, and promote skin cell turnover. Think of it as a super-charged exfoliation that goes deeper than your typical at-home scrub. Different strengths are available, from mild peels that have little downtime to stronger peels that may require a few days of recovery.

Laser treatments can target various aspects of acne, from active breakouts to leftover scars. Some lasers work by shrinking oil glands, while others target redness and inflammation. For acne scars, lasers can stimulate collagen production, helping to fill in indented scars. It's like giving your skin a remodeling job from the inside out. However, multiple treatments are usually needed for best results.

Procedural treatments offer exciting options for those struggling with persistent acne, but they're not one-size-fits-all solutions.
