I heard that once you use a sunscreen higher than an SPF 15, that there is no difference in the SPF 30s, 40s or 50s. All offer the same protection: Is this true?

While we all love the summer months for the sunshine, it can sometimes mean havoc for your skin. We asked Holly Sherrard, Education Manager at The International Dermal Institute® for her advice.
An SPF15 gives approximately 93% protection from UVB rays and SPF30 gives approximately 97% protection from UVB rays but the sunscreen has been doubled. It also measures how long a person can stay in the sun without burning. Reapplication is key when using a daylight defense product so slather on the SPF every 1-2 hours and use an ounce for the entire body and a teaspoon for the face. Also look for terminology such as "broad spectrum protection" which means a product is offering protection against UVA and UVB rays.
