Ok maybe not sugar water but a glycerin and water. Same thing right? I am not a big make-up girl BUT I do know a little. Setting spray helps to keep make-up on your face and off of your clothes or your significant other during snuggle time. Setting spray can be EXPENSIVE. MAC cosmetics sells their setting spray for US$21.00 and Urban Decay retails their version for about US$29.00.
So for a cheaper DIY version you will need:
SMALL spray Bottle
Water
Glycerin
Mix 1 part Glycerin with 3 parts water in your spray bottle and mix it up for a fresh batch of setting spray. This should be made in small amounts I would say for those people who wear make-up daily. Make enough for about 7 days in a small spray bottle.
