Laser and light-based therapies can reduce acne inflammation, bacteria, and scarring by targeting follicles, lowering sebum, and stimulating collagen; they work best as part of a tailored treatment plan with a dermatologist.
Acne starts in the pilosebaceous unit when sebum and keratinocytes block a follicle. Bacterial growth (Cutibacterium acnes) and immune response cause inflammation and pimples. Modern treatment includes topical retinoids, benzoyl peroxide, antibiotics (used carefully), hormonal therapies, and isotretinoin for severe cases.
