I've Been Using Botox for Four Years Now and As I Look at my Eyes, They Seem to Look Smaller and Smaller. Why is This?

If you use your forehead to keep your eyebrows up and your eyelids open, paralyzing the forehead with botox can result in the upper eyelids appearing heavy or more hooded.  An experienced injector will look at your natural facial movements/structure and accommodate for this.  

Of note, you can also use botox to open the eye and bring the brow up.  This is done by injecting botox into the muscle around the eye, called obicularis oculi, near the outer edge of the eyebrow.

Without ever having Botox, the areas of the forehead which are tight and in a naturally-elevated position in our twenties, start to lower in our thirties and forties.  With this, the sling support of the eyebrow / upper eyelid complex weakens and we develop "hooding" of the upper eyelids which makes the eyes looks smaller.  When my patients first saw me when they were much younger and did not exhibit lowering of the upper eyelids they underwent forehead muscle Botox injections with good results. Now that they're 10 to 20 twenty years older, the aged forehead muscle has sagged and they can't undergo the same forehead treatment to smoothen out their horizontal creases.  The Botox can be injected in the glabella between the eyebrows to decrease the vertical frown lines and this helps to lift the forehead, but not enough to compensate for the drop that the Botox injections of the forehead would create. As we age, we need to use the forehead muscle to actively elevate the droopy upper eyelids.Some patients, who never have Botox need a surgical brow lift to lift the forhead so their eyes can open more again (they also may undergo a blepharoplasty).  Without the brow lift, some patients may get a non-surgical benefit of a brow lift from Ultherapy.

It would be very helpful to look at your pictures (and pictures of your eyes from years ago).  Most likely you are referring to the aging process as your brows descend over time, your eyes start to look heavy, your upper eyelids seem fuller.  But once again, without pictures, this is just a speculation.
