Definition
Nasolabial folds, also known as smile lines or laugh lines, are the creases that run vertically from the corners of your nose down to the sides of your mouth. These folds are a natural part of facial aging and become more prominent with time due to several factors:
- Loss of collagen and elastin: Collagen and elastin are proteins that provide structure and elasticity to your skin. As you age, your body produces less of these proteins, leading to looser and less supple skin.
- Gravity: Over time, gravity pulls down on your facial tissues, deepening the existing creases.
- Facial expressions: Repeated facial expressions, like smiling and frowning, can contribute to the formation and deepening of nasolabial folds.
History
While not a medical condition, nasolabial folds have been a recognized facial feature throughout history. Their depiction in art and cultural references can provide clues about societal perceptions of aging and beauty standards across different eras.
Treatment
Several options can help reduce the appearance of nasolabial folds, but none offer permanent removal. These include:
- Dermal fillers: Fillers like hyaluronic acid can be injected to plump up the skin and smooth out the folds.
- Botox: Botulinum toxin injections can temporarily relax the muscles that contribute to the formation of nasolabial folds.
- Laser treatments: Certain laser procedures stimulate collagen production and tighten the skin, offering some reduction in fold depth.
- Facial surgery: In some cases, cosmetic surgery procedures like a facelift may be used to address nasolabial folds in conjunction with other signs of facial aging.
