I am a huge fan of clarins products. However, this is not my favourite. It work a great if you use it as a lip balm. It's super moisturizing with a matte finish.
I do not like it as a lipstick base. It's not really tacky enough to the lipstick to adhere to. I didn't find my lipstick lasted longer. It just felt more hydrating than normal. I do find it's hard to line the lips with this product on. It creates what feels like a silicone barrier. Which is great for filling lines but too silky for lip liner and lipstick to adgear to.
