Inside the cap is a little twist top that opens three holes to shake a little powder out (into the upturned lid) then simply use the twist out brush to apply to the face. I have used this both after applying my make up, and also throughout the day and love that it doesn't add any 'cake' or extra colour to the face. This means that I don't have to worry too much about having a mirror I can just apply a little to the areas I know need a little extra powder!
How cool is this packaging though? Shaped like a telescope (or one half of binoculars.) I think this is the perfect handbag companion and will definitely be keeping this in mine for those moments when I need a touch up.
Out of the three POREfessional products this is probably my least favourite just because I am not a fan of loose powders however I do think it works really well and will come in handy when travelling or going to occasions when I might want to carry a little make up with me.
