Thank you for your question. I can hear how much this asymmetry is bothering you, and I want to reassure you that a noticeably more hooded upper eyelid on one side is actually a fairly common concern. The key is figuring out why the right eyelid looks more hooded than the left, because the treatment is very different depending on the cause. The most important distinction: hooding vs. drooping When people describe one eye as “extremely hooded,” it can be due to two very different things: Dermatochalasis (excess eyelid skin) — the skin folds over the crease. Ptosis (a drooping eyelid muscle) — the actual eyelid sits lower over the pupil. Sometimes both occur together. A useful clue is whether the eyelid margin itself is lower on the right side (covering more of the iris), or whether the crease is simply buried by excess skin. Is surgery the only option? For significant asymmetry, surgery is often the most effective and predictable treatment, but it is not always the only option. If the problem is mainly excess skin An upper blepharoplasty can remove the extra skin and create a more symmetrical crease. If the problem is true ptosis A ptosis repair is usually needed to tighten or reposition the muscle that lifts the eyelid. Would they operate on only one eyelid? Yes, they can. It is very common for surgeons to perform unilateral upper blepharoplasty or unilateral ptosis repair when one side is clearly more affected. However, many surgeons will carefully evaluate both eyelids, because sometimes the “normal” side has mild hooding as well, and treating both sides can produce better long-term symmetry. The decision depends on: the degree of asymmetry, brow position, eyelid crease height, and your personal preference. Can Botox help? Sometimes — but only in specific situations. Botox can improve the appearance if the asymmetry is caused by: one brow sitting lower than the other, or overactive muscles pulling the brow downward. A carefully placed brow lift with Botox can create a few millimeters of improvement, which may make mild hooding less noticeable. Botox will not correct significant excess eyelid skin or true eyelid ptosis. In fact, if Botox is placed incorrectly around the forehead or brow, it can sometimes make the hooding appear worse by allowing the brow to drop. What about filler? Filler is rarely a good treatment for a heavily hooded upper eyelid. In some patients with sunken upper eyelids (superior sulcus hollowing), a very small amount of filler can make the upper eyelid look less hollow and less skeletal, but it does not remove excess skin and would not usually be used to correct a markedly hooded lid. If the problem is fullness or drooping, filler could actually make the upper eyelid look heavier. My overall impression Since you describe the right eye as “extremely hooded” and very different from the left, I would be thinking first about whether there is true eyelid ptosis in addition to hooding. Here is how I would generally think about the options: Mild asymmetry from brow position → Botox may help somewhat. Upper eyelid hollowing making one side look deeper → Filler may occasionally help, but this is uncommon. Noticeable excess skin or a lower eyelid position on one side → Surgery is usually the most effective and durable solution. The encouraging part is that you would not necessarily need surgery on both eyelids. Many patients with a clearly more hooded right eyelid are successfully treated with a unilateral upper blepharoplasty, a unilateral ptosis repair, or a combination of the two, depending on the underlying anatomy. If I were counseling a patient with your description, I would be cautious about trying to “camouflage” a significantly hooded eyelid with Botox or filler alone, because those treatments tend to provide limited improvement and can sometimes create additional asymmetry. A careful eyelid examination to determine skin excess vs. muscle drooping vs. brow asymmetry is the most important step in deciding whether a non-surgical approach has a realistic chance of helping.
