What is photoaging?
Photo aging means premature skin aging caused by repeated exposure to ultraviolet radiation (UV rays) from the sun and artificial UV sources. Prolonged sun exposure accelerates the process of skin aging. The harmful UV rays damage the important proteins of the skin - collagen, elastin, and fibers which are responsible for the youthful skin.
Sunlight is the main source of UV light. Ultraviolet radiation is composed of uva, UVB, and UV rays. Uva rays penetrate the skin deeper, harming the epidermal layer and the dermis, also damaging the collagen and elastin tissues. Thus, uva rays are the culprit behind photoaging, which includes wrinkling, leathery, sagging and other light-induced aging. Uvb rays penetrate the epidermis causing sunburn. The uvc rays have more energy and do not get through our atmosphere. The UV rays damage the DNA of the cells causing mutations, leading to premature aging and skin cancers.
Early signs of photoaging-
- depigmentation and appearance of pigmented spots - freckles, lentigines
- fine lines around the eyes, mouth and frown lines on forehead
- spider veins on the face and neck
- loss of lip color and fullness
With continuous exposure to sunlight over the years, there is deepening of the creases and increase in a number of wrinkles. Skin becomes leathery and sags.
How can I prevent photoaging?
Photoaging is a cumulative process that happens over the years.
- avoidance of sunlight by staying indoors between 11am-3pm when the sun's UV rays are strongest
- sun protective clothing
- wear a broad spectrum sunscreen with a minimal SPF of 30 and repeated 2hourly application of the same
- sunscreen is to be applied to all the sun exposed areas face, ears, neck, lips, hands
