I purchase the Catrice Prime and Fine primer in the green shaded option for skin that is prone to redness. I battle with some broken capillaries around my cheeks and nose area due to incessant nose blowing from allergies. Because of this endless I like to try to 'mask' this.
This primer is so well priced it almost feels like your cheating! It is a smooth gel like consistency and absorbs into the skin leaving it covered, smooth, with reduced pores and an even base to carry on with the rest of your make up.
I do find that this shade of green is a bit too dark and that it melts into your skin a bit too fast and sometimes doesn't cover all the red areas that you want but that is quickly trumped by adding another layer and then continuing with your makeup routine.
