Lip fillers efficiently boost thin lips and make them soft and plump with a fuller look. Thin lips result from age-related or genetic loss of collagen, giving them a light and wrinkled appearance. Additionally, sun damage and habits like smoking lead to the loss of collagen and elasticity of the lips. Lip fillers, after injection, start improving the collagen network and the skin fibres' elasticity. Regular filler treatment can boost thin lips and give them an attractive yet natural look.
