UV exposure: the most effective dietary supplements

Exposure to the sun's ultraviolet (UV) rays has benefits, such as vitamin D synthesis, but also carries significant risks to skin health, including sunburn, premature aging, and an increased risk of skin cancer. UV rays are divided into three categories: UVA (320–400 nm): Penetrate deeply into the skin, responsible for skin aging and contributing to cancer risk. UVB (280–320 nm): Penetrate the skin's surface layer, cause sunburns, and are directly involved in the development of skin cancer.

Risks Related to UV Exposure

Sunburn: An acute burn of the skin caused by overexposure, characterized by redness, pain, and sometimes blisters. Repeated sunburns increase the risk of skin cancer and accelerate aging. Skin Aging: Chronic UV exposure leads to loss of skin elasticity, wrinkles, and pigmented spots. Skin Cancers: Cumulative UV exposure is the main risk factor for skin cancers, including carcinomas and melanomas.

Prevention and Protection

Limit Exposure: Avoid the sun between 10 a.m. and 4 p.m., when UV rays are most intense. Wear protective clothing, sunglasses with UV protection, and a hat. Use Sunscreens: Apply a high-protection sunscreen (SPF 30 or higher) against both UVA and UVB. Reapply every two hours, after swimming, or after excessive sweating. Prepare Your Skin: Take supplements rich in beta-carotene, selenium, and zinc to strengthen the skin's antioxidant defenses. A one-month course before and after exposure is recommended. In case of sunburn: • Moisturize the skin with a soothing aloe vera–based lotion. • Drink plenty of water to compensate for dehydration. • Apply cool compresses to relieve pain. Protecting your skin from UV is essential to prevent short- and long-term damage. Adopting a prevention routine, using suitable products, and limiting exposure during critical periods can significantly reduce the risks associated with sun exposure. If severe symptoms such as extensive blisters or intense pain occur, consult a healthcare professional.
