Which nonsurgical procedure would minimize the appearance of a horizontal crease between the eyes? (photo)

Hi! the line you are noticing is part of the Glabella muscle. The best form of treatment for that concern is a toxin, to help relax the muscle and lift it, which would decrease the "angry look" you are referring to. It is best to stay consistent with your treatments, going every 3 months or so, as consistency will help to decrease the strength of the muscle over time.

Botox would soften the bulgy muscle above and an appropriate HA filler would elevate and smooth the residual crease. Just make sure to consult with an expert, board certified cosmetic dermatologist since this area of the face is not a zone to be left to the hands of an inexperienced, novice filler injector. Best of luck.

This area can be improved with Botox which you stated you have tried. It is a high risk area for fillers. If you are only considering nonsurgical options you may want to consider Morpheus8. This treatment combines RF technology with microneedling to improve overall skin tone and texture. Three treatment sessions are recommended for optimal results.

The lines you see are called Procerus creases, which are caused by overactivity of Procerus muscle that runs vertically here. While the glabellar complex muscles are treated in tandem, care has to be taken in your case to deliver optimum botox units specifically to Procerus. This is an extremely high-risk area for fillers so your best bet in addition to Botox is to add on high-intensity focused ultrasound (HIFU) lifting.
Wishing you the best,Dr. Daphney Gracia Antony
