LOVE this product
I cannot wear the padded nose piece on my eyeglasses and need the plastic nosepiece which is a part of the frame.  My glasses never fit quite right, and especially in the heat of summer, when my face gets oily and shiny, the ALWAYS slide down.  I decided to give Nerdwax a try, and from the first application, I was in love!!  It did the trick whether my face was clean, or if I had makeup on, or if I perspired from the hot weather!!  It is non-invasive and leaves no stickiness on your nose, and is not noticeable on the nosepiece, either.  The frames "do NOT slide"!!!  It has no noticeable odor.  Depending on the weather, I usually apply the product 2X per day - you should no need more, unless you clean your glasses often.  This is a staple in my list of favorite products, and I do not leave home without it!!  Cannot say enough good things about it.  You will be so happy if you have a slippage problem and order this as a fix!!
