We're sorry it sounds like you are having trouble with your refill.
If you have our original brush your new refill cartridge will screw onto the base of the brush to replace the one that is there, but if you have our new brush style, you will need to pour the powder into the powder reservoir in the base of the brush. You may need to tap it lightly at an angle and rotate a bit to get all the powder out.
We hope this helps, but if you need further assistance, please reach out to our customer service team.
“Using the Mineral Powder Sunscreen Cartridge is an excellent choice to save some money! Our whole family uses this product, including our grandchildren, and it has proven effective especially when traveling and needs to be applied frequently. So easy to use and the children never complain that it stings their eyes!”
“Love the look and effect of this product. I am not fond of a heavy makeup look. So this provides a good cover for me with sun protection also,. Use it daily....”
