Muscle loss after upper bleph & ptosis repair, any way to re-stimulate these muscle groups?

1 yr ago I got a unilateral upper bleph & ptosis repair on my left eye. Now there has been significant changes in both brows that is beyond herrings law. I used to have these mscular bulges above both brows (about 1 inch), which contributed to more masculine and prominent brow ridge. Eye brows used to look thicker and fuller. Now, Ive noticed in camera and mirror that those muscular bulges are flattened now, leaving with me a deflated, older, emascualated look. What are my options? No pics
