Sun Protection Factor (SPF) is a laboratory measure of the effectiveness of sunscreen. The higher the SPF, the more protection a sunscreen offers against UVB which causes sunburn.
Sunscreen filters light from the sun, lessening UV penetration to deeper layers of the skin. It is recommended that sunscreen is applied regularly (eg. every 20 – 30 minutes) to retain topical UV light filtering qualities.
Combined sunscreen/moisturizers and lotions are common. Sounds like a great idea? A sunscreen’s function is to filter UV light from the outermost layer of the skin. The purpose of a moisturizer is to hydrate and enrich deeper layers of the skin, therefore a combination product may not be as effective as one would desire.
Sunscreen is only required during daylight hours for those parts of the skin exposed to sunlight.
Fulom Moisturizing Cream or Hydrating Lotion provides excellent skin hydration to the deeper layers of skin. During daylight hours, Fulom Moisturizing Cream or Hydrating Lotion can be applied as the base to enrich the skin, and sunscreen can be applied on top to filter harmful UV radiation.
