The Effects of Sun Exposure Without Sunscreen

1. The dangers of sun exposure without preventive measures

a. UVA and UVB Radiation: The Invisible Threats

Every time we go outdoors, we are exposed to two main types of ultraviolet (UV) radiation: UVA and UVB. Although both can be harmful, they differ in their impact on our skin. UVA rays penetrate deep into the dermis, the thickest layer of the skin, causing long-term damage such as wrinkles and premature aging. UVB rays, on the other hand, often damage the epidermis, the most superficial layer of the skin, resulting in sunburn and, in more serious cases, skin cancer.

b. Cell damage and premature aging

UV rays can cause cell damage, leading to the formation of free radicals. These unstable molecules can damage skin cells and disrupt collagen and elastin, vital components for keeping skin firm and elastic. When this happens, the skin may begin to show signs of premature aging, such as wrinkles and fine lines.

2. The vital role of facial sunscreen

a. UV ray blocking

Facial sunscreen acts as a shield, absorbing, reflecting or dispersing UV rays. This helps prevent damage to the skin, significantly reducing the risk of sunburn, premature aging and skin cancer.

b. Protection against cell damage

In addition to blocking UV rays, many facial sunscreens contain antioxidants that help neutralize free radicals. This further protects the skin from cellular damage and promotes healthier, younger-looking skin.

3. The importance of correct and consistent application of facial sunscreen

It is essential to apply sunscreen to your face every day, even when it is cloudy, as UV rays can penetrate clouds. In addition, it is important to apply it correctly and in the right amount. Remember that the skin around your eyes and neck also needs protection.

Choosing the right facial sunscreen is equally crucial. Look for one with a sun protection factor (SPF) of at least 30 and that offers Broad Spectrum protection, that is, one that protects from both UVA and UVB rays.

Likewise, it is important to remember that the effectiveness of facial sunscreen decreases over time. Sweat, water, and simple friction can cause it to fade, leaving your skin unprotected. That's why it's essential to reapply sunscreen every 4 hours and after swimming, sweating, or towel drying.

When reapplying, be sure to cover all exposed areas, including the edges of your face, neck, and ears. If you wear makeup, consider using sunscreen in spray or powder format, which can be easily applied without ruining your look.

Conclusion

In short, the effects of the sun without proper use of facial sunscreen can be harmful and long-lasting. By including facial sunscreen in our daily skincare routine, we are taking an essential step to protect our skin, preserve its health, and prevent premature aging. So, before going out, don't forget to apply your facial sunscreen. At the end of the day, prevention is always the best strategy, and there is nothing like feeling and looking healthy with well-cared-for and protected skin.
