One of the most important secrets of Hollywood stars is sunscreen cosmetics.
Protected every day, summer and winter from the harmful effects of solar radiation, the skin retains its appearance for a long time. On the other hand, excessive exposure to UV radiation can have catastrophic effects.
Even if you do not want to abandon the natural tan, it is extremely important to know the harmful effects of the sun on your skin that constantly accumulate on each unprotected exposure to UVA and UVB radiation.
1. Skin Discoloration
Tanning is an effect of the sunburned skin. To defend against harmful radiation, the skin produces more melanin and thus its ability to defend decreases over time.
Besides the brown spots that can appear due to prolonged exposure to the sun, light patches can also appear on the skin. With a diameter of 2 to 5 mm, discolored dots on the skin generally occurs in arms and legs, below the knee.
Perhaps the most obvious effect of the sun on your skin is its prematurely aging. Exposure to sunlight for years reduces the thickness of the superficial skin.
Moreover, the skin is less hydrated because it not retains sufficient moisture. Sun hurry the emergence, of fine wrinkles, especially around the eyes and mouth that betrays your age or even make you look older.
3. Changing of the Skin Texture
The appearance change of the skin is easily noticed by anyone, but also its texture is disrupted by excessive exposure to sunlight. In the medium and long term, the sun contributes to loss of skin elasticity and even the emergence of thicker skin areas. They occur in areas exposed the most to the sun, such as the hands or neck.
4. The Highlighting of Blood Vessels
The blood vessel walls become thinner over time with exposure to UV radiation. They may become more visible, but the unpleasant effect of this is the rapid appearance of bruising. Mild trauma that would not cause bruising in areas less exposed to sunlight, can affect skin’s appearance, especially on the hands and arms but also in other areas, if you prefer a completely natural tan.
5. The Emergence of Sunspots
Without an adequate protection against UVA and UVB, reddish spots may also occur on the skin. These precancerous lesions known as solar keratoses appear only in areas exposed to the sun and cause itching or burning especially for people with pale skin. These spots, which occur most often in groups, increase the risk of skin cancer by 10-15%.
6. An Increased Risk of Cancer
All 3 types of skin cancer, malignant melanoma, basal cell carcinoma and squamous cell carcinoma have a higher risk of occurrence when the skin is exposed to the sun without protection.
Melanoma has the highest risk of metastasis, but all are dangerous skin cancers and the ultraviolet exposure without adequate protection increases the risk of development.
