Short answer: the SMAS is a facial support layer and the basis of a family of facelift techniques. Deep Plane is an approach that works beneath it and releases selected retaining ligaments. This is not simply a comparison between superficial and deep surgery. Methods differ in their extent and tissue mobilization, and no option consistently proves best for every patient in appearance, recovery or longevity. Ask which structures your surgeon plans to treat and why that plan fits your anatomy and risk profile.

The right choice depends on anatomy, facial aging pattern, skin quality, neck laxity, previous surgery, medical history, recovery planning, candidate selection and the surgeon’s experience with the technique being proposed. This article explains the difference in plain English while keeping the surgical details accurate enough for patients comparing options, including sub-SMAS/deep-plane dissection, scar placement, scar visibility and candidate selection.
What is the SMAS layer?
SMAS stands for superficial musculoaponeurotic system. It is a fibrous layer beneath the facial skin and superficial fat, connected to deeper facial structures and involved in facial expression and soft-tissue support.
SMAS-based techniques include suturing, folding, removing portions of the layer and elevating flaps. Their extent varies, and some include sub-SMAS dissection and ligament release. SMAS should therefore not be presented as one superficial operation. A systematic review published in 2026 compared different methods within this family.
What is a Deep Plane facelift?
A Deep Plane facelift works in a deeper anatomical plane, beneath the SMAS. The surgeon releases selected facial retaining ligaments, such as zygomatic and masseteric retaining ligaments, so the cheek and jawline tissues can move as a more integrated unit.
This approach is especially relevant when midface descent, jowling, nasolabial fold depth and neck contour are part of the same aging pattern. Because the repositioning is carried by deeper tissues rather than the skin alone, the goal is a more natural vector of lift and less visible pull on the skin.
My approach to Deep Plane surgery has been shaped by formal plastic surgery training, more than 20 years of practice, more than 8,000 surgeries, and continued learning from Dr. Tim Marten and Dr. Mike Nayak in the United States during ASAPS Meetings. That continuing education informs technique, but it does not replace individualized assessment and careful surgical judgment.
Deep Plane vs SMAS: the practical differences
| Question | SMAS facelift | Deep Plane facelift |
|---|---|---|
| Main layer addressed | A family of methods that modify the SMAS, with or without flap elevation. | Dissection goes beneath the SMAS in selected areas. |
| Retaining ligaments | Ligament release varies with the specific technique. | Selected ligaments are released to mobilize deeper soft tissue. |
| Skin tension | Support distribution varies; excessive skin tension should be avoided. | Designed to place more support on deeper tissues and less on skin. |
| Midface | The effect depends on the technique and extent of tissue mobilization. | Addresses selected midface tissues; universal superiority has not been established. |
| Neck and jawline | Can improve jowls and jawline in selected patients. | Often planned with neck lift or deep neck work when cervical aging is present. |
| Recovery | Varies by extent, anesthesia and patient factors. | Also variable; deeper dissection does not automatically mean a harder recovery. |
| Longevity | Depends on anatomy, technique, aging, skin quality and habits. | May be durable in well-selected patients, but aging continues and no fixed duration should be promised. |
Is Deep Plane always better than SMAS?
No. Deep Plane is not automatically better than SMAS for every face. A patient with early laxity, limited midface descent or a need for a smaller correction may not need the same operation as someone with heavier jowls, cheek descent and neck laxity.
The plan should match the anatomy. A mini-facelift describes an operation of variable extent, whereas Deep Plane describes an anatomical approach. An August 2026 review reported favorable Deep Plane aesthetic outcomes, but assessment was subjective and further comparative studies and long-term follow-up were needed. That does not establish one best operation for everyone.
Why retaining ligaments matter
Facial retaining ligaments act like anchoring points between deeper structures and superficial soft tissue. When the cheek and jowl descend with age, simply pulling skin or tightening a superficial layer may not fully address these tethering points.
Deep Plane surgery releases selected ligaments so the soft tissues can move in a more vertical and anatomical direction. This is one reason the technique is discussed so often in relation to midface rejuvenation and natural-looking facial movement.
How this fits regenerative facial planning
Many patients do not age in only one layer. They may have deep soft-tissue descent, neck laxity, eyelid skin excess and volume loss at the same time. Within the approach described as Regenerative Deep Plane, facelift surgery may be combined with blepharoplasty and facial fat grafting when each component has a clear indication.
Fat grafting should be described responsibly. Transferred fat can restore selected areas of volume, and adipose tissue contains stromal and adipose-derived cells that are being studied for their biological properties. That does not make facial fat grafting a stem-cell therapy, and it should not be sold as a guaranteed way to regenerate skin.
Recovery: what patients should expect
Recovery after either technique depends on the extent of surgery, anesthesia, bleeding tendency, smoking, skin quality, revision history and whether eyelids, neck or fat grafting are added. Many patients plan for roughly two weeks away from highly visible social or work commitments, but some need more time and some return sooner to low-demand activities.
Swelling, bruising, tightness, numbness and temporary asymmetry can occur. Sudden swelling, worsening one-sided pain, bleeding, fever, drainage or skin color changes require prompt assessment. A painful, swollen calf needs urgent evaluation. Shortness of breath, chest pain or sudden neurological symptoms require emergency care; do not wait for a message reply.

Questions international patients should ask
International patients comparing facelift options in Brazil should ask practical questions, not just marketing questions:
- Does the surgeon have active Brazilian CRM registration and an RQE in plastic surgery, verifiable in the CFM directory?
- Where is the surgery performed, and what anesthesia support is used?
- Which anatomical findings make Deep Plane or SMAS appropriate in this case?
- Will the neck, eyelids or facial volume need separate planning?
- How long should the patient stay in Londrina before flying home?
- Who monitors the early postoperative period and warning signs?
- What is the plan if revision surgery has been done before?
Cost references reviewed on September 8, 2026: in my practice, Deep Plane face and neck surgery is referenced at BRL 73,500 without facial fat grafting or BRL 85,000 with fat grafting, for payment in full upfront with the maximum discount. At an illustrative exchange rate of BRL 5 per USD, these amounts equal approximately USD 14,700 and USD 17,000, a difference of USD 2,300. These are my practice’s references, not national averages or a current exchange-rate quote. The USD equivalent changes with exchange rates; the indication, inclusions and final quote require individual assessment.
Travelling to Londrina: accommodation, transport and personal support
We can begin with an online consultation before you arrange your trip to Londrina. An in-person preoperative consultation is still required; when the first consultation was online, that preoperative visit has no additional consultation fee.
My team provides accommodation guidance in Londrina, including hotel or Airbnb options. Accommodation is booked and paid for separately. We can recommend a trusted driver and a companion or caregiver. The driver and companion/caregiver are available to hire separately, at an additional cost.
During your stay in Londrina, you have support with dressing care and frequent in-person follow-up appointments with me. After you return home, we continue online follow-up until one year after your surgery.
Before booking, confirm the accommodation location, transport to appointments and companion requirements with my team. Your length of stay and clearance to travel depend on an in-person assessment and your individual recovery.
Frequently asked questions
Is SMAS outdated?
No. SMAS facelift techniques remain valid and can be appropriate for selected patients. The question is whether the chosen method matches the patient’s anatomy, expectations, risk profile and desired degree of correction.
Does Deep Plane last longer?
There is no consistent evidence that Deep Plane lasts longer than every other SMAS technique. Standardized comparisons and long-term follow-up are still needed. Results also change with anatomy, aging, skin quality, habits, weight changes and the operation performed.
Is Deep Plane recovery harder?
Not necessarily. Deeper anatomical work does not automatically mean a harder recovery, but the total recovery depends on the extent of surgery and whether neck lift, blepharoplasty or fat grafting are added.
Can Deep Plane be used in revision facelift?
Sometimes, but revision cases require particular caution because scar tissue, altered anatomy and previous vectors change the surgical plan. Patients considering repeat surgery should read more about revision facelift and discuss timing carefully.
How I make the decision
I do not choose Deep Plane because it is fashionable, and I do not dismiss other SMAS-based techniques because of their name. I choose based on anatomy. In the consultation, I assess the cheek, jawline, neck, skin quality, volume loss, previous procedures, health history and the patient’s ability to follow recovery instructions.
