Brow Lift vs. Endoscopic Forehead Lift: Which Is Better for Sagging Eyelids?

As we age, both the eyebrows and the upper eyelids can begin to sag. However, these are two different problems, and treating one does not always correct the other. Understanding the difference between a sub-brow lift and a forehead lift is essential when choosing the right procedure for a more refreshed and natural-looking appearance.

1. What Is the Difference Between a Sub-Brow Lift and a Forehead Lift?

A sub-brow lift and a forehead lift may sound similar, but they address different areas.

A sub-brow lift involves removing a small amount of excess skin directly beneath the eyebrow. This helps lift the upper eyelid skin and improve heaviness around the eyes. It does not directly lift the eyebrow itself.

A forehead lift, also known as a brow lift, raises the eyebrows by lifting and repositioning the forehead tissues. Depending on the technique, the procedure may involve incisions along the hairline or small incisions within the scalp, including endoscopic techniques.

The key difference is simple: a sub-brow lift primarily addresses excess upper eyelid skin, while a forehead lift primarily corrects a low eyebrow position.

2. Why Can the Eyes Look Smaller After a Sub-Brow Lift?

One concern after a sub-brow lift is that the distance between the eyebrows and the eyes may appear shorter.

As the upper eyelids begin to sag with age, many people unconsciously use their forehead muscles to raise their eyebrows and keep their eyes open. This compensation can make the eyebrows appear higher than their natural resting position.

When a sub-brow lift removes excess skin, the upper eyelids become less heavy. As a result, the forehead muscles may no longer need to work as hard to keep the eyes open, allowing the eyebrows to return to a lower, more relaxed position.

For some patients, this change is natural and desirable. However, if the eyebrows descend too far, the eyes may appear crowded or heavy, creating a less refreshed appearance.

This is why surgical planning is important. Removing too much skin in an attempt to eliminate every sign of eyelid sagging can lead to an overly tight appearance or an unnatural relationship between the eyebrows and the eyes.

The goal should not be to remove as much skin as possible, but to achieve an appropriate balance between the upper eyelids and the eyebrows.

3. Can a Sub-Brow Lift Leave Visible Scars?

Because a sub-brow lift involves removing skin, a scar is unavoidable. The goal is to place the incision where the scar can blend as naturally as possible with the existing eyebrow line.

The visibility of the scar depends on factors such as skin characteristics, incision placement, wound healing, and the amount of tension on the incision.

The inner portion of the eyebrow can be particularly challenging because the hair pattern is often less uniform in this area. Extending the incision too far toward the inner eyebrow may make the scar more noticeable in some patients.

For selected patients, focusing the correction more toward the middle and outer portions of the eyebrow may help reduce scar visibility, although the appropriate approach depends on the pattern of sagging.

Eyebrow makeup or carefully selected cosmetic tattooing may help camouflage a healed scar in some cases. However, these options cannot guarantee that a scar will become invisible.

4. Can a Sub-Brow Lift Cause Difficulty Closing the Eyes?

Excessive skin removal during a sub-brow lift can create too much tension around the upper eyelids and may interfere with normal eyelid closure.

This is one reason why removing every bit of excess skin is not necessarily the best approach. A natural result requires careful consideration of the eyebrow position, eyelid skin, and the patient’s ability to close their eyes comfortably.

The amount of skin removed should be determined according to the patient’s anatomy and functional needs, rather than focusing exclusively on making the eyelids look as open as possible.

5. When Is an Endoscopic Forehead Lift a Better Option?

An endoscopic forehead lift may be appropriate when the eyebrows themselves have descended and contribute to a heavy or tired-looking upper face.

By lifting the forehead tissues and repositioning the eyebrows, the procedure can improve the appearance of brow descent and may also reduce some of the heaviness over the upper eyelids.

However, if the upper eyelid skin itself is significantly excessive, lifting the eyebrows alone may not fully correct the eyelid problem.

In these cases, treating the eyebrow position and the upper eyelid skin as separate concerns can lead to a more balanced surgical plan.

6. Should You Have a Sub-Brow Lift or a Forehead Lift First?

The best procedure depends on which structure is primarily responsible for the patient’s concerns.

If excess upper eyelid skin is the main issue and the eyebrow position is appropriate, a sub-brow lift may be considered.

If the eyebrows have descended significantly, a forehead lift or brow lift may be more appropriate.

When both eyebrow descent and upper eyelid skin laxity are present, combining procedures may sometimes be considered. In other cases, a staged approach may be preferable, with one procedure performed first and the remaining concerns reassessed after healing.

A sub-brow lift is often considered first when upper eyelid skin excess is the main concern. However, this is not a universal rule. The correct sequence depends on the patient’s anatomy, eyebrow position, degree of eyelid sagging, and desired outcome.

Conclusion: Treat the Eyebrows and Upper Eyelids as Separate Problems

Aging around the eyes does not affect only one structure. Both the eyebrows and upper eyelids can descend, and each may require a different approach.

A sub-brow lift primarily addresses excess skin beneath the eyebrows, while a forehead lift raises the eyebrows themselves. Trying to correct both problems with only one procedure may lead to incomplete improvement or an unnatural appearance in some patients.

The most important step is to identify the cause of the heaviness around the eyes and choose a procedure that preserves natural proportions, comfortable eyelid closure, and balanced facial expression.

A personalized assessment by a qualified plastic surgeon is essential to determine the most appropriate treatment plan.
