Even in today’s world, people are still holding a tan that achieves a spectacular change in someone in high esteem. Beaches get overcrowded during summer time not so much for a water splash, but for a glamorous look. However, this change of skin tone is only a secondary effect of a more in-depth transformation. Once the skin is exposed to ultraviolet radiation for an extended period, it is going to suffer damages at the level of proteins and DNA. However, sunscreen chemicals are reliable shields against the sun.
What Happens to Our Skin When Exposed to UV Radiation
The sun has a yin and yang nature. On the one hand, its good ultraviolets namely UVB are helping the body produce vitamin D. On the other hand, its harmful side, namely UVA ultraviolet, is promoting risks of skin cancer. What really happens is that our skin contains molecules that can perfectly absorb both these types of sun rays.
Howver, the molecules react to overexposure to UVA. These rays are intrusive enough to penetrate the protective layer of our body, namely the skin, and infiltrate the system. Once inside, they can turn on the natural antioxidant network of the body. This can lead to damage at a cellular level, destroy collagen that keeps the skin smooth and elastic, speed up the aging process, and cause skin cancer.
Sunscreen Chemicals Containt UV Filters
However, there are two protective options. One of them is to avoid overexposure to UV radiation as much as possible. The other one lies in sunscreen chemicals. These are upgrading the skin with UV filters. Such sunscreen chemicals are actually molecules that impair UV rays from penetrating the surface of the skin. Their main defense mechanism is either forming a protective barrier or reflecting UV radiation from reaching DNA.
Now when summer is at the door, The Skin Cancer Foundation, American Cancer Society, the American Academy of Dermatology, together with worldwide specialists encourage citizens to protect themselves from the sun. If you enjoy sunbathing, don’t forget about sunscreen chemicals. You should also choose a water resistant product for lasting effects.
