Rocky Mountain’s SPF 50 bottle is a refillable solution for family outings to the beach, pool, or other outdoor locations. SPF 50 provides increased UVB protection for extended outdoor activities. The enhanced bonding-based formula is ideal for those who are active while in the sun. Our proprietary formula interlocks with the skin’s upper layer, keeping pores open thus allowing the skin to breathe and perspire, keeping the body naturally cool. Rocky Mountain sunscreen is formulated for use as a daily lotion and defends your skin against damaging UV radiation, extreme dry weather, and wind burn. Rocky Mountain sunscreen exceeds 2012 FDA testing standards for UVA and UVB broad spectrum protection. Rocky Mountain sunscreen reduces the risk of sunburn, skin cancer, and early skin aging"s when used with other sun protection measures (limit time in the sun from 10 am-2 pm, wear long-sleeved shirts, pants, hats, and sunglasses).
