Fotona 4D Results depend on whether all four modes are properly delivered and whether energy parameters are calibrated to your skin type. Our approach is built on authentic Fotona equipment, multi-mode protocols, and a full suite of tightening platforms.

4 MODES

Full execution of all four modes

SmoothLiftin(SmoothLiftin (intraoral) + FRAC3 (fractional) + PIANO (deep heating) + SupErficial (resurfacing) — four modes working in concert, lifting and rejuvenating from the inside out rather than addressing only the surface.

WHAT IS IT

Fotona 4D/5D/6D/7D What Is It?

Fotona®(Fotona®) 4D is aDual-wavelength (Nd:YAG 1064 nm + Er:YAG 2940 nm)a non-invasive laser rejuvenation treatment that works throughFour treatment modesCollagen activation, contour tightening, and skin quality improvement are achieved across multiple dimensions — from the intraoral layer to the skin surface. The 5D/6D/7D protocols build on the 4D foundation by incorporating additional modes and treatment areas, such as the neck, periorbital zone, and pigmentation.

Fotona 4D The core of“From inside out”Multi-dimensional lifting:The intraoral mode heats the tissue from the mucosal side to lift the nasolabial folds and lower face; the deep mode tightens overall; the fractional mode refines texture and imperfections; the surface mode brightens skin tone — all four working together to deliver a naturally”Laser lifting”results.

The standard 4D protocol is non-ablative with minimal downtime; results develop gradually as the body’s own collagen is stimulated.

Why there are”Intraoral”Mode? SmoothLiftin Heating from the oral mucosal side targets the nasolabial folds and lower face from within,”Inner / medial”,This is an angle that surface-based lasers cannot reach — and it is precisely what makes the Fotona® 4D intraoral approach to lifting the nasolabial folds uniquely effective.
HOW IT WORKS

Fotona 4D How it works

The dual-wavelength laser delivers heat through four distinct modes — intraoral, deep, fractional, and surface — activating collagen contraction and long-term regeneration to achieve”From the inside out”non-invasive lifting and skin quality improvement.

1

Consultation & Assessment

Dr. Xu assesses the degree of laxity, skin condition, and Fitzpatrick skin type to determine whether the standard 4D protocol or an extended protocol is appropriate, and whether combination tightening treatments should be incorporated.

2

SmoothLiftin Intraoral lifting

Intraoral Er:YAG heats tissue from the mucosal side, lifting the nasolabial folds and lower face.”Inner / medial”。

3

FRAC3 + PIANO Deep

Fractional energy addresses texture irregularities, while long-pulse Nd:YAG delivers deep, uniform heating to firm the skin.

4

SupErficial Surface resurfacing

Er:YAG The surface mode provides gentle resurfacing to brighten skin tone and refine overall texture as a finishing step.

5

Progressive collagen regeneration

A subtle tightening sensation is noticeable immediately after treatment. Lifting and skin quality improvements develop gradually over weeks to months. A typical course consists of 3–4 sessions.

WHY THIS MATTERS

Fotona 4D Results depend on all four modes being delivered correctly

Many clinics omit the intraoral SmoothLiftin step or reduce the number of modes, which inevitably compromises results.Full four-mode protocol + skin-type-adjusted energy settings + cumulative treatment effect,is the foundation for achieving genuine Fotona® 4D results.

Dr. Xu is proficient across multiple platforms — Fotona®, HIFU, and radiofrequency — and selects the right approach based on your individual degree of laxity, rather than defaulting to a single device for every patient.

Your Top Questions About Fotona® 4D

Fotona 4D What Is Fotona® 4D — and What Is the Difference Between 4D, 5D, 6D, and 7D?

Fotona 4D using a dual-wavelength laser'sFour modes(SmoothLiftin (intraoral) + FRAC3 (fractional) + PIANO (deep) + SupErficial (surface) — four modes working from the inside out for multi-dimensional lifting.5D/6D/7D Higher-dimension protocols (5D, 6D, 7D) build upon the 4D foundation by incorporating additional modes and treatment areas — such as the neck, periocular region, and pigmentation — with broader coverage as more dimensions are added.

Fotona 4D How Does Fotona® 4D Compare to Thermage® FLX or Ultherapy®?

Fotona 4D — Dual-wavelength, multi-mode laser with intraoral lifting and minimal downtime — well suited for mild-to-moderate laxity and skin quality concerns.Ultherapy® (HIFU) — Reaches the deepest layer (SMAS), making it suitable for deep structural laxity;Thermage® FLX (RF) — Uniform tightening across the dermis and subcutaneous layers. Significant laxity may still require HIFU or surgical options.

Is There Downtime? How Many Sessions Are Needed?

Standard 4D protocolNon-ablative, virtually minimal downtime,Most clients can resume normal activities immediately (mild flaking may occur after the SupErficial resurfacing mode). Typically 3–4 sessions per treatment course、Sessions are spaced 3–4 weeks apart, allowing results to accumulate and develop progressively.

Is Fotona® 4D Safe for Asian Skin? Is There a Risk of Hyperpigmentation?

Fotona 4D The standard protocol is non-ablative with a lower risk of post-inflammatory hyperpigmentation. For Asian skin (Fitzpatrick III–V), energy settings are still adjusted according to skin toneReduce energy settings + strict post-procedure sun protection.This further reduces the risk of PIH. Dr. Xu will design a customized energy protocol based on your skin condition.

How long do results last?

Results following a complete treatment course typically last 12–18 months,Results depend on age, baseline skin condition, and lifestyle. Fotona 4D works by slowing the progression of laxity while improving overall skin quality. Maintenance sessions every 12–18 months help sustain long-term results.

How much does Fotona® 4D/5D/6D/7D cost in Toronto or Markham?
Pricing depends on the number of dimensions selected and the areas treated, so there is no single fixed fee. At ID Cosmetic Clinic in Markham, Dr. Dan Xu provides a personalized assessment before quoting a cost, because the correct protocol varies by skin laxity, facial anatomy, and treatment goals. A consultation is the most accurate way to receive a transparent, itemized estimate.
How does Fotona® 4D actually work — what technology is behind it?
Fotona® 4D uses two laser wavelengths — Nd:YAG (1064 nm) and Er:YAG (2940 nm) — delivered in four distinct laser modes. Each mode targets a different tissue depth: one works intraorally to tighten the mucosal lining, others address superficial texture, bulk collagen heating, and skin resurfacing. The combination stimulates neocollagenesis and tissue remodeling without surgery.
Does Fotona® 4D hurt? What does the treatment feel like?
Most patients at ID Cosmetic Clinic describe a warm, prickling sensation during the laser passes rather than sharp pain. The intraoral SmoothLiftin™ step feels like mild heat inside the mouth. Topical numbing cream is applied beforehand to improve comfort. Tolerance varies by skin sensitivity and the energy settings Dr. Dan Xu selects, but the procedure is generally well tolerated without sedation.
Can Fotona® 4D be combined with injectables like Botox® or dermal fillers?
Yes, Fotona® 4D can be performed alongside neuromodulators and hyaluronic acid fillers, though timing matters. Dr. Dan Xu at ID Cosmetic Clinic typically recommends spacing laser treatment and fresh filler injections by at least two weeks to allow tissue to stabilize and avoid displacing newly placed product. When sequenced properly, the combination addresses both volume loss and skin quality simultaneously.
Is Fotona® approved or cleared for use in Canada? Is it available at Health Canada–regulated clinics?
Fotona® laser systems are used in licensed medical clinics across Canada and are operated under the oversight of regulated healthcare professionals. At ID Cosmetic Clinic in Markham, Dr. Dan Xu performs Fotona® treatments within a physician-led practice that complies with applicable Ontario and Health Canada regulatory standards. Patients should always verify that any laser clinic is supervised by a licensed physician.
