Silver-MSM Sun Lotion has a sun protection factor of 20 and filters both UVA and UVB rays for up to 90%. The Titanium Dioxide used for this purpose is of a micro particle size (called "Microfine"), it is not nano sized and therefore safe to use. Silver-MSM Sun Lotion has a non-greasy, non-fragranced formula that is absorbed into the outer skin very easily and provides a safe new sun lotion experience: No nasty artificial smells wafting around you all day long and no sticky stuff in your hair or clothes, either. It gives good, all natural (all ingredients are plant and mineral based) sun protection for the sensible user, however please note: Although this product has water-repellent qualities, we do not recommend its use for prolonged sessions of bathing. After bathing always re-apply product immediately. Silver-MSM Sun Lotion comes in a trigger spray bottle that makes it easy to apply cleanly and efficiently and is therefore very economical. Suitable for vegetarians and vegans.
