fotóöregedéshez

Fotóöregedés is the Hungarian term for photoaging, which refers to the premature aging of the skin caused by chronic exposure to ultraviolet (UV) radiation from the sun. This type of aging is distinct from intrinsic aging, which is the natural process of skin aging that occurs over time due to genetics and hormonal changes.

The primary cause of photoaging is UV radiation, which damages the DNA within skin cells and disrupts the production of collagen and elastin. These proteins are essential for maintaining the skin's firmness, elasticity, and smooth appearance. Over time, this damage leads to visible signs of aging.

Common signs of photoaging include wrinkles, fine lines, sagging skin, and a leathery texture. Pigmentation changes are also prevalent, such as age spots (lentigines), freckles, and an uneven skin tone. Blood vessels can become more prominent, appearing as telangiectasias (spider veins) on the face. In more severe cases, photoaging can also increase the risk of developing skin cancers.

Sunscreen use, protective clothing, and seeking shade are crucial preventative measures against photoaging. Treatments to address existing photoaging include topical retinoids, chemical peels, laser therapy, and microneedling, which aim to stimulate collagen production, improve skin texture, and reduce pigmentation irregularities.
