I went to Sephora's in NYC yesterday, just to play with stuff. Their liquid eyeliner is really good, but I'm not sure if there are stores in other cities. It's the store brand, and it sells for about $10. I tried it on my hand. The brush is very smooth and allows for great control, so you can have a thin or thick line without a mess. The bad thing about it is that it is totally NON-waterproof, so if you wear contacts and have to put drops in your eyes every now and then, this won't work. I did find a new product which I tried on my hand and it worked great. It's a "lipstick sealer", and it's an obscure brand that makes things of that type. It's a brush-on liquid in a small bottle for $15.00. You are supposed to brush it over lipstick, and the lipstick will become permanent. I tried it over my hand, actually over a line I made with a pencil eyeliner, not lipstick. After all the experiments I did on my hands, and rubbing off all the test lipstick and eyeshadow more than once with a plain paper tissue, and paper tissue soaked in makeup remover, everything came off my hand, except that one line of eyeliner with the sealer on top. It just stayed put like when I first put it on. Hmmmm. I think I'll go back to the store and buy me a bottle. It's about the size of a nailpolish bottle. Sephora makes a similar product, under its own brand name, for about $12 I think. I will try that one, too. But I was really impressed with this sealer thing. The line on my hand didn't start fading until I took a shower. This is not something I would wear on a daily basis. I actually like re-applying lipstick (when I wear lipstick), because that way I can empty the tube and have an excuse to buy a few more But for comps, this would be a good product. I am going to see if it can be applied over other things, e.g. eyeliner and eyeshadow, to make them permanent.
