Why use SPF sunscreen in 2023?
A good SPF (Sun Protection Factor) plays a crucial role in protecting your skin from the harmful effects of the sun’s ultraviolet (UV) radiation. Here’s how it works:
Shields against UVB rays: SPF primarily protects your skin from UVB rays, which are responsible for causing sunburns and contribute to the development of skin cancer. The SPF number indicates the level of protection against UVB rays. For example, an SPF 30 sunscreen filters out approximately 97% of UVB rays, while SPF 50 filters out about 98%.
Reduces sunburn risk: Sunburn occurs when your skin is overexposed to UV radiation. Applying a good SPF helps prevent sunburn by extending the amount of time it takes for your skin to redden compared to if you weren’t wearing any sunscreen. It provides a barrier that reflects or absorbs UVB rays, reducing their penetration into the skin.
Minimizes skin damage: Prolonged sun exposure can cause skin damage, including premature aging, wrinkles, dark spots, and sagging. By using a high-quality SPF regularly, you can minimize these effects as it acts as a shield, reducing the amount of UV radiation that reaches your skin.
Decreases the risk of skin cancer: UV radiation is a leading cause of skin cancer. By applying SPF daily, you significantly reduce your risk of developing skin cancer, including both melanoma and non-melanoma types.
Provides broad-spectrum protection: Look for a sunscreen labeled as “broad-spectrum” because it protects against both UVB and UVA rays. UVA rays penetrate deeper into the skin and contribute to premature aging and skin cancer. A broad-spectrum SPF helps shield your skin from both types of radiation.
Remember that applying sunscreen is not the only measure you should take to protect your skin. It’s also important to seek shade during peak sun hours, wear protective clothing (such as hats and sunglasses), and limit your time in direct sunlight.
