I am starting to notice crow's-feet around my eyes. Can you explain the pros and cons of collagen verses over-the-counter creams that claim to help?
Creases such as crow's-feet are caused in three ways and various treatments will address each cause. You need the right treatment to correct the cause of the problem. Creams will address fine lines and wrinkles due to sun damage and the quality of the skin.
We call creases caused by the action of the muscles around the eyes "dynamic creases", as they come and go with expression. These are best treated by selectively weakening the muscle with Botox.
If the dynamic creases are long-standing and are there at rest, when you are not squinting, then the answer is a filler such as collagen or a newer agent such as the hyaluronic acid fillers. Often a combination of treatments is needed to address the various problems and achieve the best result.
