How To Cover Pimples?

I got a pimple in my face yesterday. I need to cover it right now because I'm going to a party. I heard that green eyeshadow works but my mom doesn't have any. Please tell me what are good ways to cover it and how to treat it?

Now you can cover your acne spots and heal them at the same time. Dream Dots are invisible pimple patches which heal and conceal your spot in less than 8 hours. 

Clean and dry the pimple skin area. Centre and apply the Dream Dots over the area and press down to deal the corners for 10 seconds. Once sealed the Dream Dot will begin to heal the spot and make up can be applied over the clear invisible patch if needed.
