Sun exposure and repeated sunburns cause premature aging (photoaging), making us look older than we are. Radiations from the sun that affect the skin are UVB and UVA. UVB rays are shorter and usually cause burns. UVA rays are longer and penetrate deeper into the skin.
Photoaging has increased in recent decades due to the change in our lifestyle. When UVA rays penetrate the skin they damage collagen fibers. This leads to a reaction that will prevent collagen from rebuilding correctly and will show as wrinkles on the skin.
Skin photoaging begins at puberty, becomes more visible in the 20s and can be clearly seen in the 30s. Generally, in the late 20s and early 30s, the first signs of photoaging make their appearance.
The signs of photoaging on the skin include:
- Roughness: The skin becomes dry, rough and loses its elasticity.
- Fine lines and wrinkles: They are generated due to the loss of collagen and elastin which further cause dehydration of the skin.
- Pale color: The blood vessels of the skin are damaged and start to decrease which leads to yellowing of the skin.
- Discoloration: It appears as an intense coloration of the skin in some areas and destructs pigment cells in the skin areas that are lighter.
Once photo-aging signs have appeared on the skin, simple care products for home use are not sufficient. We need to follow special treatments by specialized cosmetics that contain substances such as vitamin A, C, or E and other antioxidants. Therefore, to decrease future photoaging, broad-spectrum sunscreen is your best sun protection over the long-term. The earlier in life you start applying it, the better long-term results it will show.
Apply higher Sun Protection Factor (SPF) which can absorb UVA and UVB light. The other most important product is a moisturizing cream, which will keep your skin hydrated and fresh.
