SPF 101: What Type of Sunscreen Should I Use?
It’s no secret that protecting our skin from the sun's harmful rays is essential for maintaining healthy and youthful-looking skin. Sunscreen plays a crucial role in shielding our skin from damaging ultraviolet radiation. However, with the numerous types of SPF products available on the market, it can be overwhelming to determine which one is right for you.
Join us as we delve into the world of SPF, explore its benefits, discuss various types of sunscreens, and provide guidance on when to wear this must-have skincare product.
What is SPF?
SPF, or Sun Protection Factor, is a measure of how effectively a sunscreen protects the skin from UVB rays, which are primarily responsible for causing sunburn. The number associated with SPF indicates the level of protection provided. For instance, SPF 30 filters out approximately 97% of UVB rays, while SPF 50 filters out around 98%.
What are the Types of SPF?
Chemical Sunscreens:
These sunscreens work by absorbing UV radiation and converting it into heat. They contain organic compounds such as oxybenzone, avobenzone, and octinoxate. Chemical sunscreens are typically easy to apply and offer broad-spectrum protection. However, some individuals with sensitive skin may experience irritation or allergic reactions to certain chemical filters.
Physical or Mineral Sunscreens:
Mineral sunscreens use natural minerals like titanium dioxide and zinc oxide to form a physical barrier on the skin, reflecting and scattering UV rays away from the skin. They are suitable for sensitive skin and are generally less likely to cause irritation. Physical sunscreens provide immediate protection upon application and are effective against both UVB and UVA rays.
Here at the Wellness Revolution office, we carry ZO® Skin Health's Sheer Fluid Sunscreen and Gel Sunscreen, both of which are SPF 50 and fragrance-free. The Gel sunscreen is great for darker skin tones as it doesn’t have any color, while the Sheer Fluid sunscreen is mineral based and boasts innovative pigment technology.
We also carry the EltaMD UV Clear Sunscreen - Stephanie’s favorite - which is packed with vitamin B3, ideal for acne-prone, skin rosacea, and hyperpigmentation.
What are the benefits of SPF?
Protection Against Skin Cancer: Regular use of SPF significantly reduces the risk of developing skin cancer, including deadly melanoma. It acts as a shield, preventing UV radiation from damaging the DNA in skin cells.
Prevents Premature Aging: Exposure to the sun's UV rays can accelerate the aging process, leading to wrinkles, fine lines, and age spots. SPF protects against photoaging by blocking the harmful effects of rays that penetrate deep into the skin.
Maintains Even Skin Tone: Sunscreen helps prevent the appearance of hyperpigmentation, dark spots, and uneven skin tone caused by sun damage. By shielding the skin from UV radiation, it aids in maintaining a more even complexion.
When should you wear SPF?
Sunscreen should be a part of your daily skincare routine, regardless of the weather or season. Situations when wearing SPF is essential include:
Daily Protection: Apply sunscreen every morning as the last step in your skincare routine, even if you are not spending significant time outdoors. UV rays can penetrate clouds and windows, so protection is necessary regardless of location.
Outdoor Activities: Whether you're going for a hike, swimming, or simply enjoying a picnic in the park, it's crucial to apply and reapply SPF every two hours, especially during peak sun hours (10 am to 4 pm).
Sun-Exposed Work Environment: If your work requires spending extended periods outdoors or near windows, ensure you apply sunscreen generously to all exposed areas of your skin.
Selecting the right SPF is essential for maintaining healthy skin and protecting yourself from the damaging effects of the sun's rays. Whether you opt for chemical or physical sunscreens, the most crucial aspect is to consistently apply and reapply SPF throughout the day. Remember, prevention is key when it comes to sun damage and maintaining a youthful complexion. So, embrace the habit of wearing SPF daily and enjoy the benefits of healthy and protected skin for years to come.
