Light therapy, also known as LED or phototherapy, is a non-invasive skincare treatment that uses different wavelengths of light to improve the health and appearance of the skin. In aesthetic wellness, it is commonly used to treat concerns such as acne, fine lines, dull skin, and inflammation. Different colors of light provide different benefits—for example, blue light helps kill acne-causing bacteria, while red light stimulates collagen production and improves skin elasticity. Light therapy also promotes better blood circulation and supports natural skin healing. Because it is gentle, painless, and requires no downtime, it is a popular treatment for achieving clearer, brighter, and more youthful-looking skin.
