As we age, wrinkles become an inevitable feature of our skin's journey. However, do you know not all wrinkles are the same? Understanding the differences between fine lines and dynamic wrinkles is crucial for effectively managing and treating them. We spoke to Dr Atula Gupta, Dermatologist, Dermatosurgeon, Paediatric Dermatologist MBBS, MD-Dermatology, Venerology and Leprosy, who explained what sets these two types of ageing lines apart, their causes, and the best approaches to minimise their appearance.
According to a 2012 study, skin ageing is a natural part of the human ageing process, manifesting uniquely across organs, tissues, and cells over time. Unlike internal organs whose ageing signs remain hidden, the skin visibly displays the passage of time.
Dynamic Wrinkles: The Lines of Expression
“Dynamic wrinkles, also known as expression lines, are primarily caused by the repetitive movement of facial muscles. They are most visible when your face is animated, such as when you smile, frown, or squint,” said Dr Gupta.
Here are the key characteristics of dynamic wrinkles:
Appearance and Location
“Dynamic wrinkles appear in areas where facial muscles contract frequently. Common sites include the forehead (horizontal lines), around the eyes (crow’s feet), and between the eyebrows (frown lines). These wrinkles are noticeable during facial expressions and may fade or disappear when the face is at rest,” added Dr Gupta.
Causes
The primary cause of dynamic wrinkles is the repeated contraction of facial muscles over time. As we express emotions, the skin folds and creases in response to the underlying muscle movements. Factors, such as sun exposure, smoking, and dehydration can exacerbate the formation of these wrinkles.

Prevention and Treatment
While it’s challenging to prevent dynamic wrinkles entirely, certain treatments can minimise their appearance. Dr Gupta said, “Botox injections are a popular option, as they temporarily paralyse the facial muscles, preventing them from contracting and forming wrinkles. Other treatments include laser therapy, chemical peels, and skincare products containing retinoids and peptides to improve skin texture and elasticity.”
Fine lines: The Permanent Marks of Ageing
Unlike dynamic wrinkles, fine lines are consistently visible even when facial expressions are neutral. These lines result from the loss of skin elasticity and the breakdown of collagen and elastin over time. Here’s what distinguishes fine lines:
Appearance and Location
The presence of static wrinkles can be seen even on a rested face. They can appear anywhere on the face but are often found in areas that have been exposed to the sun, such as the cheeks, neck, under eyes and décolletage.
Causes
The formation of fine lines is primarily due to the natural ageing process, which leads to the thinning of the skin and the loss of collagen and elastin. Environmental factors like prolonged sun exposure, smoking, and pollution accelerate this breakdown.
Prevention and Treatment
Dr Gupta said, “Preventing fine lines involves a proactive approach to skincare. The skin must be protected from UV damage by wearing sunscreen regularly. Skincare products containing antioxidants, retinoids, and hyaluronic acid can help maintain skin hydration and elasticity. For existing fine lines, treatments like laser resurfacing and micro-needling can stimulate collagen production and improve skin texture.”

Lifestyle Factors and Genetic Influence
Both fine lines and dynamic wrinkles are influenced by genetic and lifestyle factors. While genetics play a significant role in determining how our skin ages, adopting a healthy lifestyle can mitigate some of the effects. Key recommendations include:
- Sun Protection: Consistent use of sunscreen protects the skin from UV damage, which is a major contributor to both dynamic wrinkles and fine lines
- Hydration: Keeping the skin well-hydrated with moisturisers and drinking plenty of water helps maintain its elasticity.
- Healthy Diet: A diet rich in antioxidants, vitamins, and healthy fats supports overall skin health and resilience.
- Avoiding Smoking and Excessive Alcohol: Smoking and excessive alcohol consumption can accelerate skin ageing, leading to more pronounced fine lines and wrinkles.
Bottomline
Dr Gupta concluded, “It's crucial to understand the distinctions between fine lines and dynamic wrinkles for effective skin care and treatment. Dynamic wrinkles are caused by repetitive facial movements and are most visible during expressions, while fine lines result from the natural ageing process and are always present. By adopting a proactive skincare routine, protecting the skin from sun damage, and seeking professional treatments, when necessary, you can minimise your appearance and maintain healthier, more youthful-looking skin.”
