I have used a clear silicone type of liquid that hardens when dry on my lips, but leaves them flexible.(Nexcare, Skin Crack Care) I used it for about a day,after leaving my lips alone for maybe 3 days, It helped hold everything on, then it got too wet and looked awful so I peeled it off, taking the soft layer of skin underneath with it. I didnt experiment much with it. I didnt feel it was waterproof enough. I dont know if its the same type of liquid.
