Genetics: Lips’ natural shape and size are often inherited from one’s parents. If thin lips run in your family, you’re more likely to inherit them.
Aging: With age, collagen and elastin production in the skin diminishes. Collagen, a protein responsible for skin structure and fullness, including lip volume, declines over time.
Dehydration: Inadequate hydration can impact skin health, including the lips, leading to a loss of plumpness and elasticity.
Weight Loss: Significant weight loss, whether intentional or due to health reasons, can reduce fat and volume in the face, affecting lip fullness.
Injuries or Trauma: Physical damage to the lips, such as cuts or trauma, can cause scarring and alter their natural fullness.
