What are forehead lines?
Forehead lines develop due to a combination of factors that influence both muscle activity and skin structure. Common contributing causes include:
- Repeated eyebrow movement and facial expression
- Natural reduction in collagen and elastin with age
- Sun exposure and cumulative UV damage
- Dehydration and reduced skin resilience
- Smoking and lifestyle-related oxidative stress
- Genetic facial anatomy and expressiveness
Understanding which of these factors are most influential in each individual case helps guide appropriate treatment and preventative care.
