Tanned skin is beautiful, but first wear sunblock and remember the following:
1. Lying under the sun triggers melanin production and gives you a tan. However, UVB, the wavelength shorter than UVA, reaches the skin’s innermost basal layer where cell division and regeneration occur. When this happens, the DNA is also slightly damaged.
2. UVA hits the skin layer containing elastin and collagen tissues responsible for skin structure and elasticity. With this, prolonged sunbathing does lead to premature aging.
3. Sun-damaged basal and squamous cells that fail to repair themselves successfully defect, become cancerous, and cause carcinoma. Sun-damaged melanocytes that break down unnecessarily cause melanoma.
4. All skin colors are at risk of melanoma, so everyone needs SPF. The lighter your skin, however, the less melanin you produce, the higher your risk of melanoma.
5. Prolonged sun exposure leads to pigmentation problems (e.g., brown spots) due to some melanocytes being overly triggered.
6. Blood vessels close to the skin surface contract under hot temperature. Too much sun exposure then causes thin (and sometimes broken) blood vessels in the face.
7. Sun exposure dries the skin, triggers over production of oil, and therefore exacerbates your acne.
8. The sun also saps the moisture from your hair, making it dry, brittle, and prone to breakage. Use products with UV protection factor to avoid hair damage.
9. Unprotected hair eventually changes color, like brown turning red, when lying out for long periods. So better be handy with your caps and scarves.
