Thick bulging eyebrow muscle? What’s causing this and can Botox help? (Photo)

Question

Recently I’ve noticed that my right side eyebrow muscle appears more pronounced than the left. On the right side, there’s basically a slight ridge protruding above my actual eyebrow. From straight on, it’s not really noticeable but can be seen in certain angles/lighting. What’s causing this? Can Botox help?

Anna Chacon, MD, FAAD · Answer

What you're describing sounds like hypertrophy (enlargement) or asymmetrical activity of the frontalis muscle, which is the primary muscle responsible for lifting the eyebrows. It's not uncommon for one side of the face to be more dominant or expressive, especially if you frequently raise your brows or favor one side during facial expressions.

In certain lighting or angles, this muscle activity can create a visible ridge or bulge above the eyebrow, giving the appearance of asymmetry—even if it's subtle at rest.

Yes, Botox can often help in this situation. By precisely relaxing the overactive portion of the frontalis muscle, Botox can:

Soften the appearance of the ridge

Create better symmetry between both eyebrows

Prevent the muscle from over-contracting and becoming more prominent

Proper technique and dosing are key to achieving a natural result, especially when treating small asymmetries like this. A conservative approach with touch-ups as needed tends to work best.

We are all asymmetrical to some degree and this includes our muscles.  Using Botox in this area requires caution because it could lead to the brow dropping.  Visit with an experienced injector for an evaluation.

Thank you for your question.  The bulge you are referring to appears to be your frontalis muscle which is activated when you raise your brows.  It is not uncommon for one side to be stronger than the other. Botox can help relax the muscle when strategically placed.  I recommend you find a knowledagable,skilled injector as Botox placed in this are can drop your brow.  Best of luck!

Falguni Patel, MD, FACOG · Answer

Botox can be used to relax and over time minimize the appearance of your muscle over your brow. By keeping the muscle relaxed with ongoing treatment every 3-4 months, the muscle will atrophy or become smaller since you're not utilizing it. This will give you the appearance of a flattened, smooth forehead.
