Crow’s feet refer to fine lines and wrinkles that develop at the outer corners of the eyes. They are most noticeable when smiling or squinting but may become visible at rest over time. Crow’s feet commonly develop due to repeated facial muscle movement combined with age-related changes in skin structure.
In some individuals, crow’s feet appear earlier due to genetics, facial anatomy, or lifestyle factors, while in others they become more prominent with gradual loss of skin elasticity and collagen. Although crow’s feet are a normal feature of facial ageing, assessment can help determine whether management or treatment may be appropriate.
Symptoms and appearance
Crow’s feet typically present as fine lines radiating outward from the outer corners of the eyes. In early stages, they may only be visible with facial expression, such as smiling or squinting. Over time, these lines can deepen and remain visible even when the face is at rest.
The appearance of crow’s feet can vary depending on skin thickness, sun exposure, muscle activity, and overall skin quality. Some people may also notice associated skin texture changes or dryness in the outer eye area.
Common causes of crow’s feet
Several factors may contribute to the development of crow’s feet.
- Repeated facial muscle movement, particularly from smiling, squinting, and eye expression, plays a central role in the formation of dynamic lines around the eyes.
- Age-related skin changes include thinning of the skin, reduced collagen and elastin, and decreased skin resilience, which allow lines to become more pronounced over time.
- Sun exposure can accelerate collagen breakdown and contribute to earlier development of fine lines in the delicate periocular skin.
- Genetic factors influence skin type, elasticity, and the tendency to develop wrinkles in certain facial areas.
- Lifestyle factors, such as smoking, chronic sun exposure, dehydration, and inadequate sleep, may further affect skin quality and contribute to the prominence of crow’s feet.
How crow’s feet may be assessed
Dermatologists who consult at Northside Dermatology may assess the depth and pattern of lines, whether wrinkles are dynamic or present at rest, skin quality and elasticity, facial muscle activity, and relevant medical history. This assessment helps guide whether management may involve preventative skin care, lifestyle measures, dermatological treatments, or no intervention, depending on individual findings and clinical diagnosis.
