The next time you have some red wine you aren’t so crazy about or you let it sit around just a little too long, well here is your solution: put it in your bath! Not only will it make your bath seem more luxurious, it will also help soften your skin. About a glass (or 3/4 cup – 1 cup) of any red wine added to bath water should do the trick. The resveratrol in red wine is known for making skin firmer and improving elasticity. So if you’re pouring yourself a nice glass of red wine before you take a bath, don’t forget to pour some in the tub!
