Will I have visible scars from a facelift?

Scars after a facelift are always visible but typically not noticed. The scars are generally inconspicuous and fairly well hidden. But even under the best of conditions with ideal scars, if a person were examined closely the scars can always be found. This is one reason why hair stylists can always tell if their client has had a facelift. They know where to look for the scars and will find them if they are present. Fortunately, most people are not going to examine you as closely and diligently as your hair stylists and therefore these scars are not usually noticed.
I hope this help you understand the surgery just a little better. Good luck and enjoy your procedure.

Its unclear and unpredictable. If you develop bad scars, there are solutions. Keloid management must follow a protocol approach. Our office uses a
combination of Vbeam laser, Kenalog IIT, scar modulation, scar serum
therapy, and enucleation.

Thank you for your question. In most healthy people without a history of healing irregularities, the surgical scars resulting from a well-performed facelift are rarely an issue. Incisions are designed to result in scars that are concealed within natural curvatures in around the ear and at or within the hairline. Most patients consider those scars to be acceptable with makeup within 1-2 weeks. Scars mature naturally over months. Once mature, most scars are imperceptible in normal social interactions, although not invisible upon closer scrutiny. Ultimately, the vast majority of patients consider the results of the facelift and appearance of facial rejuvenation to be a very acceptable trade-off for typically inconspicuous scars.

Thank you for your question. While scars will always be present, much
can be done to make them as subtle as possible. Facelift incisions can be
managed using a multimodal approach:
1) Scar massage - starting as soon as the surgical dressings come off and the incisions are sealed
2) Silicone sheets or scar gels for about six months to year
3) Fractionated lasers to help blend the scar into the background -
done as a series, starting about 4 weeks after surgery and repeated
every four weeks for six months.
4) Sunscreen to prevent the scars from darkeningYour incisions
should be very subtle based on the placement of the incisions, but may
need a full 6 months to 1 year or more to fade.

The scars from a facelift are in front of and behind the ears. They all fade nicely and are barely visible after one year post op.

Anytime a surgical incision is made, scarring is an inevitable consequence. Plastic surgeons use meticulous surgical techniques and attempt to place incisions where they will be well-hidden, but even these maneuvers don't always make them disappear.
Facelift incisions are placed in front of the ear, behind the ear, underneath the chin, and in areas of hair growth. These areas are chosen because scars are minimally visible in these locations. Furthermore, hair growth, make-up, and jewelry can also help to make scars less noticeable in these locations.
Wound-healing is also important and varies from patient to patient. Patients with lighter skin coloration tend to have less noticeable scar formation than patients with darker skin tone. This genetic variation accounts for many of the differences we see in how wounds heal.
Wound healing goes on for a year following facelift surgery and during this period, gradual improvements can be expected. Scars will tend to flatten and lose their redness as time passes.
It's important to remember that scarring occurs in all facelifts. Scar revision may be necessary in rare cases if scarring is noticeable. In most facelifts, scarring is minimal and patients report high satisfaction rates.

Whenever a cut is made a scar will result. This is a basic tenet in Cosmetic Surgery.  However, every effort is made to have a precise cut without tension and to have adequate sutures without excess. These efforts will help to provide the best healed scar possible.

All surgical procedures produce permanent scars and Facelifts are no exception. Although facelift scars are probably  visible to the patient and surgeon who know exactly where to look and do so close up, they are generally not noticeable by everyone else and are also easily camouflaged by light makeup if they are. The likelihood of exceptionally hidden or non visible scars often relates to the experience of a skilled board certified  plastic surgeon. Through their years of training they understand how to  place these scars in areas which are well-hidden by using existing anatomy, creases and technical skills such as prevention of tension. Further in the unlikely event  the scars become hypertrophic (ropy) during the early period they are skilled in how to make them fade away. The good news is that it's  uncommon in my experience for my facelift patients to complain about a visible scars. 

By and large, facelift incisions are visually concealed or hidden in natural creases or are done in a curvilinear fashion so that over time it is almost imperceptible in front or hidden inside the ear or hairline. These can often be blended so that in the first month they are perceptible only within your comfort zone. Then, after 6 weeks they are almost imperceptible if placed correctly.

There are different forms of facelifts with variations on where the incisions are made, so the scars depend on that. In general they are around the ear, tucked into places where they are very inconspicuous. One important thing is where it transitions into the hairline above the ear. Traditionally it goes behind the hairline where it is completely hidden, but this can displace the hairline upward which looks odd and is a tipoff to a facelift. An alternative is to go across at the sideburn, which works very well and avoids that problem. Another important trend is to reshape the face by working on the layer under the skin; this not only looks more natural by avoiding the pulled look, but helps take tension off the edge of the skin where it is sewn together. This makes for very thin scars, and the quality of the scar is often as important as the location.

I agree with most of the above posts.
The keys to having "good" Facelift scars is as follows:
1. Proper incision placement
2. Minimal tension in closing
3. Meticulous hand-sewn closure
4. Proper trimming of skin flaps
You should discuss each of these points with your surgeon before your procedure
