This is called the Crow’s feet wrinkle because the line formed looks like the radiating lines of the feet of the crow. The wrinkle disappears when here is no expression movement. However, during an advanced stage, the wrinkle can be present even without expression movement, by which time it becomes a static wrinkle. a static wrinkle will require a filler, such as the Restylane, perlane, Juvederm, to fill up the deficient tissues. It takes many years before a wrinkle can develops into a static wrinkle.
The under eye area, which can be called the eye bag lines can also be injected. This is very much falling under the domain of much advanced Botox injection therapy. Special care need to be taken because it can cause fluid collection when the muscle action is totally lost.
Many of the oriental, especially the mongoloid race, the Chinese, Japanese or the Korean have a very small horizontal eye slit, call it a small eye aperture. Such small eye can be treated by injection of 2 units of Botox at the mid-pupilary line that intercept the pre-tarsal muscle. Take precaution not to over treat. Always under treat, top up if necessary. This will open the eye bigger. Avoid going too laterally as it can cause rounding effect of the eye.
