How to get rid of crow’s feet

Crow’s feet arise from repeated expression

“Crow’s feet” are the creases that radiate outward from the outer corners of your eyes when you smile or squint.  They begin to show up for most people in the mid 30’s to early 40’s.  They are thought to convey sincerity when you smile (see this video about the SQUINCH by photographer Peter Hurley).  The crow’s lines can make you look more photogenic, but if you have too many or they are too deep, they make you look older.

“Crow’s Feet”


How do I get rid of them?


Use a broad-spectrum sunscreen of at least SPF 30 and preferably a mechanical blocking agent like zinc oxide.  Even while you are driving, your face is exposed to damaging UV radiation that causes aging signs and wrinkles. Other ways to prevent these lines from forming or worsening, use scientifically-proven topical creams like a prescription-strength retinol and a vitamin C  (L-ascorbic acid).   I don’t recommend that you stop smiling in order to prevent smile lines.  You may look younger, but you will lead a less happy life!


Botulinum toxin type A (Botox, Dysport, Xeomin) are liquid protein injections that selectively relax the muscles that create the crow’s lines.  An expert injector can do wonders by placing small amounts of Botox in just the right places.  Botox done well looks natural and gives your eyes a younger glow.


Lasers (fractional CO2 and erbium) and chemical peels (glycolic, TCA, phenol) will remove the outer skin layers leaving space for newer, smoother skin to take over.  In the case of crow’s feet, if you continue to crease with repeated expressions, the lines will eventually return.  A combination of resurfacing with Botox as maintenance will provide the longest-lasting results.

What about fillers like Juvederm or Restylane?

Fillers have a limited role in treating crow’s lines but can be helpful in smoothing very deep, fixed creases.  Dermal fillers can also stiffen and plump the skin to limit the amount of folding and creasing that occurs when you squint.

What about eye lift surgery?

A lower or upper eyelid lift may somewhat reduce crow’s feet but is not a good choice if your primary target is expression lines. Surgery is better for heavy upper eyelid skin or lower eyelid bags.

How long does Botox last?

Botox starts to work after a few days and lasts for months.

How many months is the big question.  I’ve been treating patients with cosmetic botulinum type A since my residency days in New York City and I’ve administered thousands of Botox injections.  On average, Botox lasts about 4 months.  But, this isn’t the case for everyone.  Why?

Botox works better with successive treatments.

The smoothing effect on wrinkles is a result of targeted muscle relaxation.  When a muscle isn’t moving as much as it used to, it begins to shrink.  Just like when you remove a cast from your arm that has been there for 2 months, the arm looks smaller. With the next Botox treatment, your muscle may take longer to recover because it’s smaller.  I have some patients that see Botox results for 6 – 9 months, mostly if they have been getting treatments for a few years.

What if Botox lasts less than 4 months?

The most likely reason for a shortened duration of action is under-treatment.  My first consideration would be to look at how many units were used and perhaps a stronger treatment is required.  There is a rare possibility of developing antibodies to the Botox molecule,  but this is unusual.  Some doctors advocate the use of supplements that improve the absorption of zinc in your diet.  These supplements may help but they’re not completely reliable.

Botox remains the most popular cosmetic treatment in the world so the length of effectiveness is acceptable to most people.
