I use fake lashes during dates or special occasions to make my lashes look fuller. I use a small amount of adhesive that specialize in keeping the lashes on the whole day with some waterproof protection. The layer of protection is really helpful when you need it, like the other day I forgot my umbrella and it rain. I didn't have anything on me and I was late for work so I just ran under the rain with a jacket over my head to shield myself as much as possible. Miraculously my lashes was still in tact when It got wet. I don't recommend to wash your face off to try it's effectiveness but this is what happened. Hope it helps.
