I got a sample from Sephora called Too Faced Extreme Lip Injection. It burns like heck when you put it on. The burning lasts for about 3 minutes and you do notice a nice plumping effect because of the increased circulation. I ordered some DuWop Venom Lip Plumper Tinted Glosses from Sephora also that have gotten good reviews. I absolutely love Sephora and all its products and you can find whatever you need there.
