You have several options to improve your forehead. You can have a forehead lift chemically by using Botox or Dysport. You have to find a physician who is competent in this technique as they are not routinely done. Using Botox or Dysport will give you a forehead lift that will last approximately three to four months and will not change your hairline position.
If you want something more permanent, you can get a direct brow lift. A direct brow lift is done by making an incision above the eyebrow and removing skin. This is an effective way to do a brow lift, however it has some drawbacks, which should be discussed with your physician.
The last technique is making an incision directly in the hairline, which allows you to do a brow lift without changing the hairline. This technique is excellent for your problem. There is potential for a scar or consideration of a future receding hairline. Before you do any procedure you should consult with two physicians and get their opinions — that way you will be clear on what are your best options.
