It depends on the cause. Some people just "naturally" subconsciously hold one brow higher or for unknow reasons have a more hyperactive side of their frontalis muscle. In these cases Botox or an equivalent product can be an effective treatment. It is also possible that you hold that brow up to unload the eyelid because otherwise it would droop over the pupil/iris (ptosis). In this event, a ptosis correction procedure is necessary. You need to be examined by a qualified surgeon for proper diagnosis and recommendation.
You could probably achieve significant improvement with Botox to lift the lower side and slightly lower the overly elevated side. This result can be tricky to optimize but should give you 3-4 months of benefit once the correct dose and injection placement has been determined. I hope my answer is helpful for you.

You may have underlying left upper eyelid ptosis (droopy) which causes the brow on that side to elevate in order to help lift the droopy eyelid. If that is the case, eyelid ptosis surgery is the best answer. See an oculoplastic specialist for evaluation.
At your age avoid a surgical correction. Botox can be used to provide balance to the forehead and arch.
You have a marked brow asymmetry. With some botox you may be able to lift the right and drop the left so they are more even. The other option is to lift the right side with a surgery. It may be hard to get them completely symmetrical even with a surgery.
Initially I recommend trying BOTOX correction to both sides in small unit amounts. This can take 3 weeks of injections to achieve a more symmetrical result... Fee range $1,000.
You do have a significant difference in the way the eyeballs are set within the bone, but beyond that there is quite a difference between the brows as well.
One option may be to do artistic Botox to reduce muscle activity selectively to make the brows appear more even, but many of those can fail over time and be disappointing.
Asymmetric brow elevation procedures can also be done, but Botox would be a nice start.
That is a significant difference in your eyebrows, so I am not sure Botox would give you enough lift of the right eyebrow but it is worth a try. If not, you may consider a surgical treatment to lift the right eyebrow (which is permanent).
Botox will not likely produce the effect on the right side that you are looking for. It is inexpensive and easy to do, so it may be worth a try. A right sided brow lift is the better option. See a board certified plastic surgeon. There are tons of them in Houston. Go to the American Society of Plastic Surgeons for a list.
It would be important to examine your face at rest and during movement to try and determine the cause of your uneven eyebrows. Determining the cause would help to determine what treatment might be best for you. It is possible that a non-surgical treatment, such as Botox could help and it is also possible that a surgical procedure could help. You could see a plastic surgeon, facial plastic surgeon, or possibly an oculoplastic surgeon to be evaluated.
