The sun is of course good for our body, it brings good mood and wards off depression or leads to the release of vitamin D. But as it happens - everything in moderation. If we overdo it, we can get sunburn, sunstroke or heatstroke, premature skin ageing or the much talked about melanoma (a skin tumour made of skin dye).
What damages the skin is the so-called UV radiation. This consists of the components A, B and C, or UVA, UVB and UVC. UVA are the rays that penetrate the skin and damage the cells, due to their action we experience skin aging, wrinkles, pigment spots and tumors. UVB can cause skin burns or rashes. The natural protective filter of the skin is melanin, and it could be said that there is a direct proportionality - the less melanin that can be formed, the greater the risk of skin damage.
Therefore, for staying in the sun, the use of protective creams is necessary due to the above mentioned facts, but it is also advisable to adapt your clothing or take antioxidants such as vitamin A, C, E, zinc or selenium. To choose the right cream, it is necessary to know the meaning of their labels. We are talking about the so-called SPF factors, the word is based on the English Sun Protection Factor. It refers to the ratio of the time the skin is protected by a filter to the time it takes for the skin to turn red without protection. For example, a sunscreen with an SPF of 25 will allow a phototype I to stay in the sun for 4 hours longer. Maximum protection is then provided by products with SPF 50+. In addition to choosing a suitable cream, it is also necessary to apply an adequate layer, think about renewing the coating after prolonged bathing, and protect your eyes and lips.
