With summer fast approaching, sunscreen becomes an essential part of our daily routine. No matter how strong the sun is, applying sunscreen is a crucial step to prevent not only sunburn but also premature aging caused by UV radiation.
Dermatologists emphasize the importance of sunscreen as UV rays can penetrate deep into the skin, causing “photoaging,” which leads to wrinkles and sagging.
Research shows that the impact of photoaging on the skin is greater than natural aging, making sunscreen your best defense against aging.
Understanding UV Protection: UVA and UVB
To effectively prevent photoaging, it’s essential to understand UV radiation.
UV rays are classified into three types based on their wavelength: UVA, UVB, and UVC.
The rays that reach the Earth’s surface and affect our skin are UVA and UVB. UVB is more intense and is responsible for sunburns, while UVA penetrates deeper into the skin, leading to long-term damage such as wrinkles and loss of elasticity.
Decoding Sunscreen Labels
When shopping for sunscreen, you often see terms like “SPF” and “PA.” Here’s what they mean:
- SPF (Sun Protection Factor): This indicates the sunscreen’s ability to block UVB rays. UVB is the type of radiation that causes immediate skin damage like redness and peeling.
- PA (Protection Grade of UVA): This measures the sunscreen’s effectiveness against UVA rays, which are responsible for deeper skin damage and aging.
Choosing the Right SPF
A common misconception is that higher SPF means significantly better protection.
Dermatologist Dr. Chiu explains that SPF 25 and SPF 50 only differ by about 2% in their ability to block UVB rays.
The main difference lies in the duration of protection. SPF 25 provides about 250 minutes of protection, while SPF 50 offers up to 500 minutes. For those who aren’t exposed to the sun for extended periods, SPF 25 is usually sufficient.
Tip: More important than the SPF number is the frequency of reapplication.
For effective protection, use enough product and reapply every two to three hours, especially if sweating.
Types of Sunscreens: Physical vs. Chemical
Sunscreens typically use either chemical absorbers or physical reflectors to block UV rays.
Chemical sunscreens absorb UV energy and convert it into heat, while physical sunscreens, made from ingredients like titanium dioxide and zinc oxide, reflect UV radiation. Recent advancements have made physical sunscreens less likely to leave a white cast, making them a great option for sensitive skin.
Tip: If you experience irritation from regular sunscreens, try 100% physical sunscreens, which are often better suited for sensitive skin, children, and post-procedure care.
