Mustela's revolutionary high protection sun lotions are formulated with mineral filters instead of chemical filters to provide optimum protection. Using a new generation of titanium combined with zinc oxide, Mustela sunscreen products reflect, rather than absorb the sun’s rays like chemical filters do. Mineral filters are also photostable, providing longer lasting protection that is better tolerated by children’s delicate skin. Mustela products are gentle on the skin and are effective guards against the sun's rays. Mustela sun lotions with SPF 50 are also available. Don't hide but have fun in the sun with Mustela high protection sun lotion. With Mustela, UV rays won't find a way to pierce your skin.
