I got the medium in the travel size because I wanted to try it out and I wanted to be able to to put it in my purse or bag.So first, so easy to put on. No smell that I could tell, I just put it on my legs/ calves. I have varicose veins, spider veins and I tan, but even with being tan I am self conscious of my legs. So up close, you can lightly see the spider veins still. I only did one application on this. If I did another, I'm thinking this may cover it more but people probably won't be that close.The pictures though you can tell on my foot what my veins normally look like and then my leg after I applied the coat.It was easy to wash off with soap and water. I have black Capri on, and when I crossed my leg on it, it did not leave any make up on it. I'm pretty happy with it. I didn't see if it was waterproof.For the price, it was great for my needs, matched well for me, actually was a tad light but I could get one darker shade and mix. I do recommend.
