By SPF, which stands for ‘Sun Protection Factor,’ indicates how much the product protects the skin from sunburn. This value only represents protection against UVB rays. It doesn’t indicate how well it protects against UVA rays, so the SPF value isn’t directly proportional to the sun protection power.
-SPF 15: 93% protection
-SPF 30: 97% protection
-SPF 50: 98% protection
The American Academy of Dermatology recommends a minimum SPF 30.
Broad-spectrum SPF provides protection against both UVA and UVB rays.
It’s important to remember that no product provides 100% protection from the sun. Additional precautions should always be taken along with using sunscreen. Some key measures include:
Additional Sun Protection Measures
Do not expose yourself to the sun between 11 a.m. and 3 p.m.
Seek shade whenever possible.
Use hats, protective clothing, and sunglasses.
Choose a sunscreen recommended by your dermatologist that suits your skin type and has at least SPF 30.
Apply your sunscreen 15-30 minutes before sun exposure to all exposed areas.
Reapply every 2 hours, more frequently after excessive sweating or swimming.
Remember that snow, sand, and water reflect UV rays.
Use sunscreen not only seasonally but all year round. UVA rays can penetrate glass, so apply sunscreen even indoors.
