The skin loses collagen and elasticity as the body ages.
This impacts our exterior appearance, loosening skin surrounding the neck and lower chin area, which produces jowls. When the body gains more weight than it needs, the jowls can be even more exposed.
Botox can lift jowls by canceling out the impact that muscles make when jawlines are pulled down. When Botox is injected into the nerves that stimulate these muscles, jawlines will become more contoured and lifted. While Botox is capable of lifting jowls, the effect it can have is contingent on how much sagging the skin has sustained.
