Slim lips, also often referred to as thin lips, describe lips that have less fullness and volume. According to provided information, this is a common concern for both women and men, sometimes even at a young age.
Why do lips become thinner?
The thinning of lips often becomes noticeable around the 30s. The primary reasons for this are:
- Lost Collagen: Collagen is a protein that provides structure and support to the skin and lips. As we age, collagen production decreases, leading to a loss of volume.
- Lost Hyaluronic Acid (HA): Hyaluronic acid is a substance that helps retain moisture and plumpness in the skin. A reduction in HA levels contributes to thinner, less defined lips.
In essence, the same factors that cause skin to sag also cause lips to lose their fullness.
