Do you need to protect against SPF in the winter?
SPF or “sun protection factor” is the most important thing you can do to prevent anti-aging. Products with SPF protect against the amount of UVB exposure you get. The days are shorter in the winter but cold and cloudy weather does not minimize harmful effects of UVB. Sunscreens with SPF 30 or higher are recommended by the AAD, American Acadeny of Dermatology.

Anthelios SX with Mexoryl Miracle Sunscreen
The Food and Drug Administration (FDA) approved sunscreens with Anthelios SX with Mexoryl, to be sold over-the-counter (OTC) for the prevention of sunburn and for protection against ultraviolet B (UVB) and ultraviolet A (UVA) rays. Anthelios SX with Mexoryl, has been available in Europe and other countries around the world for many years. Although the French authorities are said to be tougher than the USA they approved the key ingredient in Anthelios SX, a sunblock called Mexoryl, in 1993. It wasn’t until 2006 that the FDA approved Mexoryl in the USA.
What is sun protective clothing?
Sun protective clothing is made with fabrics that shield your skin from ultraviolet (UV) rays. When looking for fashions that help protect you from damaging ultraviolet (UV) rays look for the UPF number. UPF is similar to SPF (Sun Protection Factor), the rating system used for sunscreen products. The higher the UPF number the greater degree of UV protection the garment will give you. A UPF of 15 is good but 50+ is excellent. Sun protective clothing is constructed with denser fabrics, specific types of dyes plus some are treated with other chemicals that can boost a garment’s UPF rating. Polyester does an excellent job at disrupting UV light, nylon is good, wool and silk are moderately effective, cotton, rayon, flax and hemp fabrics score low without added treatments. Unbleached or naturally colored cotton protects better than bleached cotton. Summer weather means more exposure to the sun. This is a good time to do an Internet search and add some sun protective clothing to your wardrobe. Learn more about Sun Protection Clothing Basics at REI.
