The main cause of crow’s feet is repeated muscle movement around the eyes combined with a gradual loss of collagen and elastin in the skin. Every time you smile, squint, or laugh, the delicate skin in the outer eye area creases. Over time, as the skin loses its ability to spring back, those temporary creases become permanent fine lines. Below, we unpack exactly why this happens and what you can do about it.
Why do crow’s feet form around the eyes first?
Crow’s feet form around the eyes first because the skin in that area is significantly thinner than anywhere else on the face, and it lacks the oil glands that help keep other areas moisturized and resilient. This makes the outer eye area especially vulnerable to the effects of repeated movement and environmental stress. The result is that fine lines around the eyes often appear years before wrinkles show up on the cheeks or forehead.
The muscles responsible for squinting and smiling, primarily the orbicularis oculi, contract hundreds of times a day. Each contraction folds the surrounding skin. When you are young, the skin has enough elasticity to smooth itself out completely after each fold. As that elasticity diminishes with age, the skin holds the crease a little longer each time, and eventually those expression lines become a permanent fixture.
The eye area also produces less natural oil, meaning it dries out faster and is less protected against environmental damage. Less moisture means less flexibility, and less flexibility means the skin breaks down from repeated movement more quickly. It is a combination of anatomy and biology that makes this particular spot the first to show the signs of aging for most people.
How does sun exposure accelerate crow’s feet?
Sun exposure accelerates crow’s feet by breaking down collagen and elastin in the skin through ultraviolet (UV) radiation. UV rays trigger an inflammatory response that degrades the structural proteins keeping skin firm and supple. The outer eye area is particularly exposed to sunlight, and squinting in bright light adds extra muscle movement on top of the UV damage, making the combination especially hard on the skin.
UV radiation comes in two main forms that affect the skin differently. UVB rays cause surface-level damage and are the primary driver of sunburn, while UVA rays penetrate deeper into the dermis and are responsible for breaking down collagen fibers over time. Both types contribute to what is commonly called photoaging, which is responsible for a significant portion of visible skin aging, including the deepening of eye wrinkles.
Living in a sunny environment or spending a lot of time outdoors without proper sun protection speeds up this process considerably. Wearing broad-spectrum SPF daily and protecting the eye area with sunglasses are two of the most effective preventive steps you can take to slow the progression of crow’s feet caused by sun damage.
What role does collagen loss play in eye wrinkles?
Collagen loss plays a central role in the development of eye wrinkles because collagen is the protein that gives skin its structure, firmness, and ability to bounce back after movement. When collagen levels decline, the skin becomes thinner and less resilient. Around the eyes, where the skin is already thin and constantly in motion, this loss shows up quickly as crow’s feet and fine lines.
The body begins producing less collagen naturally starting in the mid-twenties, with production declining gradually each year. Elastin, the protein that allows skin to stretch and return to its original shape, also decreases over time. Together, this means the skin around the eyes loses its ability to recover from the repeated folding caused by everyday expressions.
Treatments that stimulate the body’s own collagen production can make a meaningful difference in how deep and prominent crow’s feet become. At Ocean Aesthetics and Wellness, our Exion RF Ultrasound Rejuvenation treatment uses radiofrequency energy and targeted ultrasound to prompt the skin to rebuild its own collagen and elastin from within, addressing one of the core biological drivers of eye wrinkles without needles or surgery.
Can lifestyle habits make crow’s feet worse?
Yes, several everyday lifestyle habits can make crow’s feet worse and accelerate their development. Smoking, poor sleep, dehydration, and a diet high in processed foods all contribute to faster collagen breakdown and reduced skin quality. These habits compound the natural aging process, meaning crow’s feet can appear earlier and become more pronounced than they otherwise would.
Here are the most common lifestyle factors that worsen crow’s feet:
- Smoking: Cigarette smoke introduces free radicals that directly damage collagen and elastin, and the repeated squinting motion from smoke exposure adds extra muscle movement around the eyes.
- Poor sleep: During sleep, the body repairs and regenerates skin cells. Chronic sleep deprivation limits this repair process and increases cortisol, a stress hormone that breaks down collagen.
- Dehydration: Skin that lacks adequate hydration is less plump and less flexible, making creases more visible and harder to smooth out.
- Skipping sunscreen: UV damage is cumulative, and even short periods of unprotected sun exposure add up over years to significantly accelerate crow’s feet formation.
- Rubbing the eyes: Frequently rubbing or pulling at the delicate skin around the eyes stretches and weakens it over time.
- Excessive alcohol consumption: Alcohol dehydrates the skin and depletes nutrients that support collagen production.
Making positive changes in these areas will not erase existing crow’s feet, but they can meaningfully slow the rate at which new lines form and deepen.
What treatments can reduce the appearance of crow’s feet?
Several non-invasive treatments can effectively reduce the appearance of crow’s feet by targeting the underlying causes, including collagen loss, skin laxity, and weakened facial muscle tone. The most effective approaches work at multiple levels of the skin and underlying structure rather than simply masking the surface.
At Ocean Aesthetics and Wellness, we offer options specifically designed to address the eye area without injections or surgery:
- EmFace Eyes: Our EmFace Eyes treatment uses synchronized radiofrequency and HIFES technology to tone the muscles around the eye and stimulate collagen production in the surrounding skin. It is a non-surgical eye lift that addresses both the skin and the underlying muscle, which is what makes it particularly effective for crow’s feet caused by expression line repetition.
- Exion RF Ultrasound Rejuvenation: This treatment delivers radiofrequency energy and targeted ultrasound to stimulate the skin’s natural production of collagen, elastin, and hyaluronic acid. It improves skin firmness and texture in the eye area, helping to soften fine lines from the inside out.
- Laser Skin Resurfacing: Our Waterlase laser resurfacing treatment removes damaged surface layers and prompts collagen renewal beneath the skin. It is an excellent option for refining the texture and tone of the skin around the eyes where crow’s feet have already become established.
The right treatment depends on how pronounced your crow’s feet are, your skin type, and your overall goals. Some people see excellent results with a single modality, while others benefit from a layered approach that addresses both skin quality and muscle tone together. If you are curious about which option suits you best, we invite you to schedule a courtesy consultation with Dr. Sugg. She will take the time to understand your goals and recommend a personalized plan that fits your needs.
