Profhilo Injection Points: The BAP Technique Explained

One of the most common questions patients ask before their first Profhilo appointment is: where exactly is it injected, and why only in those spots? Unlike dermal fillers — which are placed precisely where volume or structure is needed — Profhilo is administered at a small number of anatomically specific points designed to let the product spread naturally through the tissue. Understanding this technique helps explain both what to expect during treatment and why the aftercare rules exist.

Quick Answer

What Are the BAP Points?

The BAP technique — standing for Bio Aesthetic Points — is the standardised injection protocol developed by IBSA, the Swiss pharmaceutical company that makes Profhilo. The protocol was specifically designed around Profhilo's unique physical properties: unlike conventional cross-linked fillers that stay put, Profhilo is a free-flowing, high-concentration hyaluronic acid that spreads through the skin's dermal layers after injection.

The challenge the BAP protocol solves is distribution: how do you ensure a product that is designed to spread reaches the right areas without requiring dozens of injection points that would cause unnecessary trauma, bruising, and discomfort?

The answer is anatomy. Through cadaveric and clinical studies, IBSA identified five points per side of the face where injecting Profhilo produces the optimal spread through the adjacent tissue planes — reaching the cheeks, perioral area, lower face, and jawline efficiently from a minimal number of entry sites.

Where Are the Profhilo Injection Points?

The five BAP points on each side of the face are positioned at anatomically strategic locations. While practitioners may adjust slightly based on individual anatomy, the standard five sites on each side are:

  1. Upper cheek point — positioned at the mid-cheek, approximately at the level of the lower orbital rim. Injection here allows Profhilo to spread superiorly towards the lower eyelid area and laterally through the cheek tissue.
  1. Lower cheek point — located slightly inferior and medial to the upper cheek point, allowing spread through the central mid-face region.
  1. Pre-auricular / jaw angle point — positioned near the angle of the jaw. This site targets the lower face and jawline, allowing spread through the jowl area.
  1. Chin point — at or near the chin. This allows distribution through the mentalis area and the perioral zone.
  1. Mandibular point — along the body of the mandible (lower jaw). This targets the lower face and helps distribute product through the lower cheek and jowl region.

Combined across both sides, these 10 injection points provide distribution across the full midface, lower face, and jawline — the areas where skin laxity, crepiness, and volume depletion are most commonly treated with Profhilo.

An important note: practitioners do not always follow the BAP protocol rigidly. Experienced injectors often adapt the injection points based on individual anatomy, areas of concern, and the response seen in previous treatment sessions. The BAP protocol is a starting framework, not a fixed prescription.

Why Are These Specific Points Used?

The BAP points were not chosen arbitrarily — each location was selected for three reasons:

1. Tissue plane access. Each injection point provides access to a specific tissue layer where Profhilo integrates most effectively. The product is injected into the mid-dermis or deep dermis, where it can spread through the extracellular matrix without pooling superficially (which would cause visible lumps) or going too deep (where spread would be limited by the underlying fascia).

2. Natural spread corridors. The face has fascial planes and tissue compartments that act like natural highways for Profhilo's spread. The BAP points are positioned at entry locations where the product can flow along these corridors efficiently, reaching a much larger area than the injection site itself.

3. Vascular safety. Each BAP point is positioned to avoid the major facial blood vessels, reducing the risk of intravascular injection. The face has a complex arterial supply, and safe injection technique requires a detailed understanding of the underlying vascular anatomy. The BAP protocol is designed with this in mind.

What Does Profhilo Look Like at the Injection Points?

Immediately after each injection, a small raised papule (bump) forms at the entry site. These papules are simply the product sitting within the dermis before it begins to spread — they are visible and may feel firm or slightly tender to the touch.

What to expect:

The most important rule: do not massage, rub, or press the papules. Profhilo is designed to spread naturally of its own accord. Manually manipulating the injection sites risks disrupting this natural distribution and creating uneven integration.

How Does Profhilo Spread After Injection?

Once injected, Profhilo spreads through the skin via a process called diffusion through the extracellular matrix. The product's physical properties — its high HA concentration, its specific viscosity, and its thermal bonding structure — allow it to move through the dermis like a very thick fluid, integrating with the tissue proteins as it goes.

Unlike a conventional filler that forms a discrete gel bolus at the injection site, Profhilo creates a diffuse improvement across a wide area. Patients often describe the result not as "looking fuller" but as "looking like better skin" — because the treatment is improving the quality and hydration of the tissue rather than adding structure.

This spreading action is what makes the BAP protocol work: each injection point is a gateway into a tissue corridor that Profhilo then fills progressively. The product continues to integrate over days to weeks, which is why results are not instant — they emerge progressively as the bio-remodelling process advances.

Profhilo Injection Points for Neck and Décolletage

When Profhilo is used to treat the neck and décolletage — an increasingly common application — a modified injection protocol is used rather than the facial BAP points. The neck presents different anatomical considerations:

For the neck, most practitioners use a series of points along multiple horizontal rows, typically injecting into the mid-dermis at intervals of approximately 2–3 cm across the treatment area. The precise protocol varies by practitioner training and the specific product (standard Profhilo vs. Profhilo Body vs. Profhilo Structura).

Neck papules are typically more visible and longer-lasting than facial papules due to the thinner skin. Patients having neck treatment are advised to allow 24–48 hours for the injection bumps to fully resolve.

Before and After the Injection Points: What to Expect

Understanding the injection points helps explain the progression of treatment:

During treatment: The practitioner will clean each injection site with an antiseptic wipe, then inject Profhilo at each BAP point in sequence. Some practitioners inject both sides as they go; others complete one side and then the other. The process typically takes 15–20 minutes. A topical numbing cream is offered but many patients find it unnecessary as the BAP points are placed to minimise discomfort.

Immediately after: Ten small papules are visible across both sides of the face. These are the clearest indicator of where exactly the product was placed. Some minor redness and tenderness is normal.

Hours 2–4: Papules begin to reduce as the product starts to diffuse. By the end of the day, most facial injection sites should be flat or barely visible.

Days 1–7: Any residual redness, tenderness, or minor bruising resolves. The skin may feel slightly more hydrated, but significant visible changes are not expected this early.

Weeks 2–4: Bio-remodelling progresses. Collagen and elastin stimulation is active. Patients typically begin to notice improved skin quality, hydration, and a subtle tightening effect.

After the second session (4 weeks after the first): Results accelerate. Peak improvement in skin quality is usually visible 4–8 weeks after the second treatment — approximately 8–12 weeks after the first session.

Frequently Asked Questions

How many injections is Profhilo? The standard facial BAP protocol uses 5 injection points per side, making 10 injections total for a full-face treatment. Each injection delivers a precise volume of Profhilo at an anatomically specific location designed to maximise product spread. The neck and décolletage use a different, multi-point protocol with more injections across the treatment area.

Does Profhilo hurt at the injection points? Most patients describe Profhilo as mildly uncomfortable rather than painful. The BAP points are specifically selected to avoid the most sensitive facial zones, and the injection volume at each site is small. A topical numbing cream can be applied beforehand for patients who prefer it. Discomfort is typically brief — a few seconds per injection point — and any tenderness at the sites usually resolves within a few hours.

Can I see the Profhilo injection points after treatment? Yes — immediately after treatment you will see small raised papules (bumps) at each of the 10 injection sites. These are normal and expected. On the face, they typically resolve within 2–4 hours. They may be visible for slightly longer on the neck or in patients with thinner skin. The papules should not be massaged or pressed — they will settle on their own.

Why is Profhilo injected at specific points rather than all over the face? Profhilo's unique physical properties allow it to spread through the skin's dermal layers after injection. The BAP protocol identifies the specific anatomical locations where injecting Profhilo allows it to distribute most efficiently through the surrounding tissue planes, providing coverage across the full midface and lower face from just 10 injection points. Injecting everywhere would cause unnecessary trauma and bruising without improving the result — the strategic BAP placement is more effective.

What happens if Profhilo is not injected at the right points? Placement outside the standard BAP points can affect the distribution and effectiveness of treatment. If product is placed too superficially it may cause visible lumps that persist. If placed without anatomical awareness, there is a higher risk of hitting blood vessels or nerves. This is one reason Profhilo should only be administered by a practitioner who has been specifically trained in the BAP technique.

How does Profhilo Structura injection technique differ from standard Profhilo? Profhilo Structura is a higher-viscosity formulation designed to remain more localised at the injection site rather than spreading freely. It is typically injected into the mid-cheek and jawline areas to provide lifting and structural support, rather than at the full set of BAP spreading points. The injection technique for Structura requires a different approach — fanning or threading in some cases — and is more similar to conventional filler placement than the pure BAP spreading technique.
