SPF Amounts Within Sunscreen

The SPF (Sun Protection Factor) amount in sunscreen indicates its level of protection against UVB rays, which are the primary cause of sunburn and contribute to skin cancer. SPF measures how long the sunscreen will protect your skin from UVB rays compared to not wearing any sunscreen.

Here’s a general guideline for SPF amounts:
 
SPF 15: Provides low protection, blocking about 93% of UVB rays.

SPF 30: Provides moderate protection, blocking about 97% of UVB rays.

SPF 50: Provides high protection, blocking about 98% of UVB rays.

SPF 50+ (also known as “broad spectrum” or “very high protection”): Provides the highest protection, blocking about 98% of UVB rays.

It’s important to note that no sunscreen can provide 100% protection, and higher SPF doesn’t necessarily mean you can spend more time in the sun without reapplying. It’s recommended to use a broad-spectrum sunscreen (protects against both UVA and UVB rays) with an SPF of at least 30, and to reapply every 2 hours, or more frequently if swimming or sweating. Additionally, it’s important to apply sunscreen generously and evenly to all exposed skin.
