A: This horizontal line may improve if you inject Botox into the Procerus muscle. The action of the procerus muscle is the depress the medial angle of the eyebrows, which may present a horizontal line (as pictured) along the nasal bone. I recommend around ~5units. Being consistent with botox (every 3-4 month injections) will eventually help soften this line, and at the very least prevent it from getting deeper.

You should consider injection the entire glabellar complex (Procerus and bilateral Depressor Supercilli/ Corrugators) as a whole for maximum results.

A: 1. Botox if its muscular- if the pebbling is caused by contraction of the Mentalis muscle, a few units of botox would relax this. Treatment to be repeated every 3-4 months.

2. RF microneedling/ Microneedling if its acne scarring- this can break down scarring that may be tethering down the skin.

A: Every individual may vary in dosing. One thing to remember is that 'Dosing Duration.' As you bring down the units in an area, the duration of the results may decrease.

Personally, I like to conservatively dose my patients the first time to see how they respond. They are encouraged to take notes on their results in terms of strength, return of movement, and duration to then adjust as necessary. You can always add on more units (even as early as 2 weeks after their first injection as a touch up) but if the dose is too strong, only time can bring movement back to baseline.

The average dose to treat the glabella, forehead, and crow's feet tend to be 64u for 3-4 months of result. However, if you prefer softer results, you can dose more lightly next time.
