What’s the best product to use to plump lips? I’ve had a lot of disasters and a lot of success with a few different products. The best lip plumping products contained either Sodium Hyaluronate (which naturally occurs in the body and as an ingredient it is certified vegan and is gluten-free) or a patented ingredient called Maxi-Lip (a natural peptide blend; these peptides aren’t on any animal-derivative lists but I couldn’t 100% guarantee it’s vegan). The best strategy would be to use a product that contained both, or to alternate two separate products containing Sodium Hyaluronate and Maxi-Lip. Both Sodium Hyaluronate and Maxi-Lip are ones that tingle when you put them on.
