Due to the amount of natural ingredients in KALME Day Defence SPF25, it will need a few hearty shakes before using to ensure the ingredients are properly mixed. You may also find when applying KALME Day Defence SPF25 that you find mini white particles in the cream. This is nothing to worry about. These are particles of the pure zinc mineral sun block. Unlike other mineral SPF creams, Day Defence SPF25 contains pure zinc oxide, which is a mineral that not only provides a block from the sun rays but is also 100% non-reactive on highly sensitive skin. Zinc also helps reduce spots and inflammation on the skin.
 
The only downside of pure zinc is that it’s impossible to get it to fully combine into a completely smooth cream, so small particles of the zinc mineral appear in the cream. The amount of micro zinc particles in the cream can vary according to temperature changes. Our best advice is to blend micro zinc particles in with your fingertips when applying the cream and they will eventually melt and blend onto the skin after a few seconds.
