Thin lips: Lip serums

The sort of lip serums that are useful for thin lips are packed with hyaluronic acid, which can literally plump the lips (just a little bit) by helping them hold onto moisture. They will also contain ingredients such as peptides for boosting the strength of the lip skin by encouraging the growth of new collagen, and ceramides to help seal the hydrating elements of the serum into the lip so that they don’t instantly escape.
