Everybody knows how important it is to wear sunscreen. To protect our skin from the damaging UV rays, we must wear sunscreen. But you're mistaken if you think you're only supposed to wear sunscreen on sunny days. You've got to wear sunscreen even when the day's cloudy. In this blog, we will explain why you have to wear sunscreen for face every single day and how to pick the right SPF sunscreen for you.
What is SPF?
SPF stands for Sun Protection Factor. It is a measure of how well sunscreen protects your skin from UVB rays, the type of ultraviolet (UV) radiation that causes sunburn.
The higher the SPF number, the more protection the sunscreen offers from UVB rays. For example, an SPF 30 sunscreen will block about 97% of UVB rays, while sunscreen SPF 50 will block about 98%.
SPF does not measure protection from UVA rays, which penetrate the skin more deeply and contribute to skin aging and wrinkles. Look for a broad spectrum sunscreen to ensure it protects against both UVA and UVB rays.
It's important to reapply sunscreen every two hours, or more often if you're sweating or swimming.
Types of sunscreen
Sunscreens are classified into two main categories based on how they protect your skin from the sun's ultraviolet (UV) rays:
- Mineral (physical) sunscreens contain zinc oxide and titanium dioxide which sit on top of the skin and deflect UVA and UVB rays like a shield. Mineral sunscreen is gentler on sensitive skin and are less likely to cause irritation.
- Chemical sunscreens absorb UV rays into the skin and convert them into heat, which is then released from the skin. They are usually lighter and easier to spread than mineral sunscreens and don't leave a white cast. However, some of the ingredients in chemical sunscreens can irritate sensitive skin.
Choosing the right sunscreen
Broad spectrum:
Look for a broad spectrum sunscreen to protect against both UVA and UVB rays. UVA rays penetrate deep into the skin and can cause premature aging and inflammation. UVB rays are the main cause of sunburn.
SPF:
Sun Protection Factor (SPF) refers to a sunscreen's ability to protect against UVB rays. The American Academy of Dermatology recommends using a broad-spectrum sunscreen with SPF 30 or higher for everyday use. However, a higher SPF doesn't necessarily mean better protection.
Water resistance:
If you'll be sweating or swimming, choose a water-resistant sunscreen. Water resistance is typically labeled as 40 minutes or 80 minutes. Be sure to reapply sunscreen after swimming or sweating, and according to the directions on the label, even if it's water-resistant.
Skin Type
Dry Skin:
If you have dry skin opt for sunscreens which contain moisturizing ingredients.
Oily Skin:
Choose oil-free, water-based formulas. Gel sunscreens are preferable for oily skin types.
Sensitive Skin:
Mineral sunscreens with zinc oxide or titanium dioxide are generally less irritating. Look for fragrance-free and parabens-free formulas.
Conclusion
Choosing the right sunscreen can be tricky sometimes but remember that the best sunscreen is the one you consistently use.
Make sure to consider factors like SPF, broad spectrum, and water resistance to find the sunscreen suitable for you!
FAQs
1.CAN SUNSCREENS BE WATERPROOF?
No, Sunscreens can be water resistant, but not waterproof. Reapply sunscreen after swimming or sweating even if it's water-resistant.
2.CAN SUNSCREEN BE LAYERED FOR EXTRA PROTECTION?
Layering sunscreen doesn’t increase SPF protection. It’s preferable to use an SPF 50 broad spectrum sunscreen with water resistance.
