UV radiation and collagen production in the body
We are talking about ultraviolet A (UVA)* radiation, which penetrates our skin after the first few minutes in the sun. As a result, it slowly but surely damages the skin if it is not adequately protected (e.g. by sunscreen, special UV-blocking clothing, etc.).
While natural UVA rays generally do not burn the skin, they do penetrate deeper (than UVB** rays) – into the middle layer of the skin called the dermis. This is where the dense collagen network of fibroblasts that make skin firm is located.
UVA rays that penetrate the dermis cause fibroblast destruction, leading to premature skin ageing. That’s why, unfortunately, up to 90% of the visible signs of ageing (wrinkles, lines, increased pigmentation, loss of elasticity) are a direct result of sun damage that accumulates throughout our lives. In addition, these damaged fibroblasts do not properly manage the water in the dermis, leaving the skin dehydrated and dry on the outside.
How can supplementation with collagen peptides help you in summer for “Beauty and Youthfulness” ?
If you plan to sunbathe or spend a lot of time in the sun during the summer months (travelling, outdoor barbecues, etc.), it will help you to prevent a radical reduction in the amount of collagen in the dermis and consequently a loss of skin hydration. Your skin will remain supple, hydrated and smooth throughout the summer.
*UV radiation is invisible electromagnetic radiation with a wavelength shorter than that of visible light. The sun is a natural source of UV radiation. There are 3 basic types of UV radiation – A, B and C.
Type C UV, which is very aggressive, does not reach the earth’s surface – it is almost completely absorbed by the ozone layer.
**Type B UV tans the skin and causes sunburn. Repeated and intense exposure to the sun damages DNA, which can lead to the dreaded skin cancer. This is because the repair mechanism of the cells – the melanocytes – is already inadequate at this stage.
