Thin Lips

Thin lips can be a natural trait, reflecting the anatomical structure inherited from one’s family as some individuals are genetically predisposed to have less collagen in their lips, making them naturally thinner. They might also occur when there is an imbalance between the upper and lower lips, where one appears thinner than the other.

Over time, the ageing process contributes to thinning lips as collagen production decreases, leading to reduced lip volume and elasticity. Additionally, the nasolabial fold, the ridge between the nose and the mouth, tends to flatten with age, causing a loss of youthful lip definition. The ageing process can be further contributed to by excessive sun exposure and smoking, with smoking being particularly notorious for accelerating lip ageing and causing wrinkles around the mouth. Inadequate water intake and excessive consumption of caffeine is another factor to consider in the development of dry, less voluminous lips.
