6. Lip Venom: I used this in 2009 until it was empty. Absolutely terrible, it tingled and stung more than some other ones, and made my lips redder due to irritation, but it didn’t plump or increase my lip size at all. It probably works if you have poor circulation. It is a perfect example of a beauty product that got a lot of hype but didn’t deliver results. 2/10. Plumping Ingredients: Nothing.
