Is It Possible to Receive Botox Injections in Your Higher Chest Area?

Banwen,
Botox only works on dynamic wrinkles by paralyzing the underlying muscle and prevention contraction which would otherwise result in wrinkling of the overlying skin. From your description, it sounds more like you have static wrinkles. However, if you include a pictures, we can give you more specific advice. We do inject Botox sometimes in the chest, but this is to prevent sweating, not to prevent wrinkles.

Botox is really only good for facial lines of animation. Chest wrinkles are most likely sun damage and can be treated with many different types of lasers and IPL devices.  With these treatments you have to be careful with sun exposure afterwards.
