Laser underarm whitening is a non-surgical cosmetic procedure that lightens the underarm skin by targeting hyperpigmentation and uneven skin tone. The process involves cleaning and prepping the area, then using a laser to break down excess melanin in sessions lasting 15-30 minutes. Recovery is quick, with most patients resuming normal activities immediately. Temporary redness, swelling, or mild discomfort may occur but usually resolves within a few days. Multiple sessions are often needed for optimal results. The benefits include non-invasive treatment, effective lightening, and quick procedures. While results vary, they are generally long-lasting with proper skin care.
