It goes without saying that sunlight is absolutely necessary to maintain human life. However, superfluous quantity of solar beams can traumatize skin cells. Damaged cells are no longer capable to function properly. As a result, skin cells grow old prematurely, perish or start the regenerating process, which causes malignant tumors. To prevent pathological cell changes, it is necessary to protect the skin, using special sun-protection cosmetic.
Sun protector history began 70 years ago. The modern cosmetic industry offers a great variety of sun-protection products. The assortment of sun-protection cosmetic includes creams, sprays, gels, pencils, powder, and lotions. All sun-protection cosmetics can be divided into three groups: dry, liquid, and aerosol protectors.
The chemical composition of sun-protection creams, gels and sprays is well-balanced, however, to competently choose the sun-protection cosmetic, one should read sun protector descriptions. Sun protector descriptions list the basic ingredients and dwell how these ingredients influence the skin and epidermis.
Dry sun-protection products include pencils and powder. They are designed to protect primarily small parts on one's face (e.g. eyes, forehead, nose, cheeks, and chin). Dry protectors have a low degree of ultra-violet protection. They contain mineral micro particles which ward off solar beams from the skin surface.
Liquid sun-protection products incorporate gels, creams, and lotions. Sun protector description says that these products provide combined mineral and chemical filters protection. Mineral micro particles reflect only 20 % of ultra-violet beams, so, 40 % of ultra-violet radiation would get into the skin surface. Chemical filters are created with substances containing benzene, metoxycinnamate oxide, and other UV filters, and are designed to transform ultra-violet radiation into thermal energy, thus precluding solar radiation from getting into the skin. A small part of ultra-violet radiation still reaches deep skin layers and damages epidermis. Thus, there is a risk that free radicals can be produced, which would lead to dysfunction of cells and moisture deficiency.
Sun protector description may tell a lot about how damaged epidermis cells get restored and how the negative impact of free radicals is neutralized with help of natural substances called antioxidants. Among natural antioxidants are vitamin E and vitamin C. They effectively contribute to adequate cells functioning and increase immunity of epidermis cells. Besides, vitamins prevent skin from drying and premature ageing.
Finally, it is worthwhile saying that having a tanned skin can be appealing and very attractive. However, there is nothing healthy about burnt skin. One should always weigh all pros and cons when exposing oneself to the direct influence of sun rays without any sun protection. The old saying teaches us that an ounce of protection is worth to pounds of cure. Apply the sunscreen before sun-burning and let everyone enjoy the sleek healthy look of your tanned skin.
