In some cases, the Botox spreads to the outer portion of the muscle on one side, but not the other side. In these cases you may see only one eyebrow peaked.
They may recommend getting an additional injection on the side of your face where the eyebrow appears higher. This may help to relax your muscle and make the brow line look more even. In cases where one eyebrow is noticeably lower than another, some people have plastic surgery to correct the mismatch.
Botox injections of the forehead typically involves the frontalis muscle which is responsible for raising the eyebrows. An eyebrow droop can also occur as a result of over-relaxation of the frontalis muscle, while trying to erase horizontal forehead lines and wrinkles.
Answer: An easy fix
It is not uncommon for Botox injections to uncover a previously unnoticed assymmetry of the brows. The side with the stronger muscle pull will lift higher. One quick and simple addition of just 2 units into the stronger side usually evens things out.
The muscle tone in your face can change your eyebrow shape as well. The muscle tone is stronger on one side which means one of your eyebrows will sit higher than the other. By the way, this is usually everyone's favourite eyebrow. Muscle tone is the amount of tension in muscles.
A: Minor eyebrow asymmetry is a fairly common problem. However, significant disparity in eyebrow heights could be a result of an imbalance in the muscles that elevate and depress the brow. Unrecognised ptosis (droopy eyelid) of the left upper eyelid can be an underlying cause.
“When one brow is higher than the other it can make you look like you're raising your eyebrow, or that the bone structure and facial shape are uneven,” she says. “Let a brow pro reshape and even out the brows so that they are perfectly aligned.”
Botox takes between 3-7 days for the results of treatment to be fully noticeable. At times, results may look slightly uneven at first, because the Botox may “kick in” at different rates.
Differences in the position of the eyebrows can be caused by many things: over plucking, a stronger muscles on one side, bony differences, or caused by eyelid position. To be thorough and safe, you may need to see an eye doctor to make sure your eyes and eyelids are normal.
The difference in growth can be caused by the side of your face that you sleep on, which puts emphasis on one side, or the weakness of muscle movements in the brows. It makes total sense, as sometimes our eyebrows grow differently and can be hard to maintain to look similar.
Surgery used to be the only solution for asymmetrical eyebrows. These days, Botox can be used to raise the eyebrow higher up or even lower the brow, if so desired. Botox is injected directly into the appropriate muscle depending on whether the eyebrow needs to be lowered or lifted.
Many of us have one eyebrow higher than the other or one eyebrow that is fuller than the other. We might spend time in front of the mirror tweezing to even them out and filling in other areas where necessary in attempt to achieve symmetry.
If you're finding that your brows are a little more uneven than they used to be, this could be due to much hair removal, anti-ageing injections or Ptosis (a drooping or falling of the upper eyelid caused by weak muscles).
Brow Asymmetry
Eyebrow asymmetry can often be improved through brow lift surgery, depending on the nature of the asymmetry. When asymmetry is an issue, sometimes the surgeon will focus on lifting one side of the brow more than the other in order to even out the elevation of the brow.
Answer: Botox wearing off unevenly
It is common for people to have asymmetrical muscles. Depending on your anatomy and the amount of product injected, Botox could wear off unevenly. I recommend returning to your injector to discuss your concerns.
Underlying health conditions: Because thyroid function affects both your skin and the hair on your head, a thyroid condition can lead to brow thinning. Anemia (a common blood disorder) or deficiencies in iron, vitamin D, biotin or zinc can also slow or stop hair growth.
You can not raise one eyebrow because the whole muscle is connected to both eyes. It is possible that one side is not connected or less connected but that's usually not the case and such a person would not be able to raise both eyebrows at will.
“The time-friendliest way to fix an over-plucked brow is to use a brow pomade to fill in the hollow and sparse areas of the brow,” says Lerma, who recommends using this brow pomade from Anastasia Beverly Hills to underline the brow and lightly feather in a shape that mimics the natural appearance of hair growth.
The results from Botox last anywhere between 2-6 months; the average result lasts about 3-4 months. Why does Botox eventually stop working? Your body makes new neurotransmitters all the time, so the “blocking” effect of Botox gradually wears off as these chemicals start circulating in your body again.
“When an area of the face is frozen with absolutely no wrinkles, you can assume the person has had a date with a needle.” "When you look at a photo and see an area of the face that is extremely smooth and shiny," Rusher says, "that can be an indicator that the person may have had Botox."
Your physical activity level – Proteins needs time to get into the muscles after they are injected. The facial expressions made while working out could make your muscles contract much faster and cause the Botox to wear off.
A skilled plastic surgeon can improve asymmetry through a brow lift by lifting one side more than the other. This can create a more even and balanced look, in addition to improving the appearance of sagging eyebrows, forehead wrinkles and the vertical lines between your eyebrows.
