Understanding the Importance of using an SPF on your Skin in the Sun

What is SPF? Sun protection factor (SPF) represents a sunscreen's ability to protect against a specific portion of ultraviolet (UV) light called UVB. UVB rays are responsible for sunburns and skin cancer.

For day-to-day use, pick a sunscreen with an SPF of at least 30. If you spend time outdoors, choose a product with SPF 60 or greater. In reality, most people do not use as much sunscreen as they should, and this higher SPF helps compensate for the reduced application.

Should sunscreen come before or after other products?

So long as the sunscreen is at least SPF 30, water-resistant and broad-spectrum, it doesn’t matter in what order you apply your skin care products. Some people find it’s easiest to work with bare skin — before makeup or moisturizer have been added. Find what works best for your routine.
