Sunscreens - Which one is for me?
Navigating the sunscreen aisle can feel overwhelming. With so many options and abbreviations, how do you know which one to choose? Here’s a simple guide to help you understand sunscreens and find the right product for your needs.
Understanding SPF
SPF stands for Sun Protection Factor, which measures how well a sunscreen protects against UVB rays—the rays that cause sunburn.
- SPF 15: Blocks about 93% of UVB rays.
- SPF 30: Blocks about 97% of UVB rays.
- SPF 50: Blocks about 98% of UVB rays.
While higher SPF offers slightly more protection, no sunscreen can block 100% of UVB rays. Additionally, SPF does not measure UVA protection, which is equally important.
The difference between SPF 30 and SPF 50 is only about 1%, so higher SPF numbers don’t always mean significantly better protection.
Broad-Spectrum Protection (UVA and UVB)
Look for sunscreens labelled "broad-spectrum", as they protect against both:
- UVB rays: Cause sunburn and play a key role in skin cancer (think B for BURN).
- UVA rays: Penetrate deeper into the skin, causing aging, pigmentation and increasing the risk of skin cancer (think A for AGING).
Types of Sunscreens
- Chemical Sunscreens
- Contain active ingredients like avobenzone, octinoxate or homosalate.
- Absorb UV rays and convert them into heat.
- Lightweight and easy to apply, making them suitable for daily use.
- Mineral Sunscreens (Physical Sunscreens)
- Contain zinc oxide and/or titanium dioxide.
- Form a protective barrier that reflects UV rays.
- Ideal for sensitive skin and children, as they are less likely to cause irritation.
Water-Resistant Sunscreens
If you plan to swim or sweat, opt for a water-resistant sunscreen. These products specify how long they remain effective (e.g., 40 or 80 minutes).
Important tip: Sunscreen should still be reapplied every two hours or immediately after swimming or towel drying, so opting for a product with over 2 hours of resistance isn’t necessary.
Special Features to Consider
- Tinted Sunscreens: Provide a natural glow and even skin tone - great for daily wear!
- Oil-Free or Non-Comedogenic: Perfect for acne-prone or oily skin.
- Sensitive Skin Formulas: Look for fragrance-free and hypoallergenic options to reduce irritation.
How much to apply?
Use about a teaspoon of sunscreen for each body part (face, arms, legs, etc.). Reapply every two hours or immediately after swimming or sweating.
Key Takeaway
The best sunscreen is the one you’ll use regularly! Choose a product that fits your lifestyle, skin type, and activity level. Remember, no matter what sunscreen you pick, using it correctly and consistently is what truly matters.
