In the summer I'm not sure if it is me glistening (women in the South don't sweat, we glisten) or if I'm just a freakin' oil slick but my face powder is hard pressed to last all day and foundation? Forgettaboutit. Does De-Slick help? Meh to lord no.
At the end of the day my face make-up was still pretty much in place (powder aside but I lean on my hands at my desk so that's expected). For foundation this seems great. Just keep it away from eyeshadow.
Price: $12/.51oz and $29/4oz
The packaging delivers the product really well and is sturdy enough to be thrown in luggage. Not very pretty though.
It seriously makes my eye shadows crease. I rather reapply powder throughout the day than deal with creased shadows. It does hold on to foundation fairly well though.
For a product that is difficult to use/doesn't work well it is very pricey.
Avoid putting it on your eye shadows if you're going to use it at all!
