I have been using the Clarins Instant Light Natural Lip Perfector for a while now. I would say about 4 months. It has lasted me that long because I don't use it everyday but as and when I feel like a natural/nude lip colour. Although it can be used with a lipstick, I really like using it on its own. The available shades are mostly nude natural looking colours so if lipstick is not your thing, I would definitely give these a try. They come in a soft squeezable tube of 12ml so it's quite a generous amount and should last quite a while. I love the sponge-fabric applicator, it just glides on and has a sweet delish taste. It has a very nice caramelish smell and really does moisturize your lips. I did find that the applicator can get messy over a period of time, but besides that, it really is value for money and is really effective in keeping lips nice and moist and oh that smell! Very addictive! Love it!
