Which type of light is relevant to beauty therapy and affects skin ageing?

Ultraviolet (UV) light is particularly relevant to beauty therapy and has a significant impact on skin aging. UV light is divided into two main types: UVA and UVB. UVA rays penetrate the skin more deeply and are primarily responsible for photoaging, leading to the breakdown of collagen and elastin, which are essential for maintaining skin elasticity and firmness. This degradation results in wrinkles, fine lines, and a leathery texture, contributing to the visible signs of aging.

In beauty therapy, understanding the effects of UV light is critical for recommending appropriate sun protection measures and treatments aimed at combating its damaging effects. This includes advising clients on the use of sunscreens, seeking shade, and wearing protective clothing to minimize UV exposure.

Other types of light, such as visible light, infrared light, and X-ray light, do not have the same level of influence on skin aging as UV light does. Visible light can have some effects related to pigmentation and certain skin conditions, while infrared light primarily affects deeper tissues rather than contributing directly to the aging process of the skin. X-ray light, associated more with medical imaging, is not commonly relevant to beauty therapy and its effects on skin aging. Therefore, UV light stands out as the most pertinent type of light in discussions
