Nasolabial folds (commonly called laugh lines) are no longer just a concern for older adults. In the U.S., everyone from people in their 20s to those over 50 struggles with these signs of time. According to the American Society of Plastic Surgeons (ASPS), nasolabial fold filler is the second-most popular non-surgical cosmetic procedure nationwide. Meanwhile, a Harris Poll found that over 8 million U.S. Cosmetic patients deal with filler fatigue. Why are these lines so stubborn, and how can we address them scientifically?

Does Deeper Nasolabial Folds Mean More Aging? US Dermatologists Share Science-Backed Solutions

1. 3 Key Causes of Deepening Nasolabial Folds

Genetics and age lay the groundwork—if your family has a history of prominent nasolabial folds, you’re far more likely to develop them. But environmental factors and habits are even more alarming: Daily UV exposure exceeding 2 hours for two consecutive years (without protection) can reduce the skin’s elasticity around the folds by 27%. After age 40, collagen loss accelerates at 1%-2% per year; by 50, collagen levels in the skin drop 30%-50% compared to your 20s, thinning the dermis and worsening 凹 Smoking and repeated exaggerated facial expressions (like squinting or laughing forcefully) speed up fat pad descent, deepening the lines further.
