Sper lotion is a baby sunscreen lotion that uses 2 percent zinc oxide, 7.5 percent octyl methoxy cinnamate, 6 percent oxybenzone and 2 percent avobenzone. Octyl methoxy cinnamate, oxybenzone and avobenzone are all used to improve how the body can absorb and break down UV rays from the sun before they can potentially cause damages to the skin. Zinc oxide is also added to apply a soothing sensation to the skin while helping create a strong barrier of protection. Sper lotion is a sunscreen product that is especially useful for children to use as it protects them from dangerous UV rays while outdoors. Use under medical supervision.
