This product is like foundation/bronzer for your legs. Genius! It provides coverage and colour to make legs look tanned and flawless. Covers up veins or bruises while bronzing and some also provide some sparkle for nights out. I've used this stuff on my legs, my arms, my stomach.... And my friend who is a makeup artist admitted to using it on her face once when she ran out of Dior AirFlash (side note: I'm not sure if it is recommended for face use haha).
The trick I found to applying it (to make sure it looks natural and fully blended) is to spray it on your legs or in your hand and then apply lotion to your legs as you blend the two together.
I then let it dry before putting on clothes.
Warning: be careful when wearing white because it could show up.
Happy strutting :)
