Underarm rejuvenation refers to a range of cosmetic procedures and treatments aimed at improving the appearance and condition of the underarm area. This area is often a concern for both aesthetic and functional reasons, including issues such as dark pigmentation, excess hair, sweating, and skin texture. Unwanted underarm hair can be effectively reduced or removed using laser technology. Laser hair removal targets hair follicles, preventing regrowth and providing long-lasting smoothness. It can also help reduce the incidence of ingrown hairs. Mild chemical peels containing ingredients like glycolic acid or salicylic acid can help exfoliate and lighten darkened skin. Products containing ingredients such as hydroquinone, kojic acid, vitamin C, or niacinamide can help lighten pigmentation over time. Some laser treatments, such as fractional lasers or Q-switched lasers, can target pigmentation and promote skin rejuvenation. This non-invasive procedure uses microwave energy to target and eliminate sweat glands in the underarms, providing long-term reduction in sweating.
