How long the effect of a full face lasts and what goes into the plan

Quick answer

Full face is a treatment plan for the whole face, not a product. That is why the effect does not have a single end date, and each part lasts a different time. In studies, botulinum toxin lasts 3 to 4 months, hyaluronic acid filler usually lasts 6 to 18 months and poly-L-lactic acid biostimulator can reach about 2 years after the sessions. These timeframes vary from person to person, and maintenance is decided at the in-person consultation.

What full face is

The truth is that many people come to the consultation thinking full face is a product, and it is not. Full face is a treatment plan for the whole face, in which each area gets what it needs. That is why two people can have a full face and leave with treatments that are quite different from each other.

A well-planned full face is not about filling everything, it is about knowing where, how much and why to treat each area. On one face, the plan may be hyaluronic acid in the chin and botulinum toxin in the forehead. On another, it may be collagen biostimulator and skin care, with no filler at all. The name is the same, but what goes into each plan changes.

Why I look at the face in layers

Aging is three-dimensional. We age in the skin you can see, in the fat underneath and in the bone. A review published in the Aesthetic Surgery Journal describes facial aging in exactly that way, as a three-dimensional process involving bone, soft tissue and skin, in which change in one layer causes changes in the others.

Full Face 3D is the name I give to the way I plan treatment based on that. Each layer has a specific treatment:

  • Bone. Over time, the bones of the face remodel and recede, and what sits on top loses support. I work on that support with structural hyaluronic acid, at points such as the chin, the jawline and the cheekbones.
  • Fat. The fat compartments lose volume or shift, and folds and shadows appear. Here hyaluronic acid comes in small amounts, only where it is missing.
  • Skin. Collagen breakdown increases and production decreases, and the skin becomes thinner and less elastic. For the skin I use collagen biostimulator, microfocused ultrasound and skin care. Botulinum toxin comes in to soften expression lines.

How long each part of the plan lasts

How long the effect of a full face lasts is one of the questions I hear most here in Fortaleza. Since it is a set of procedures, there is no single date. Each part of the plan lasts a different time, and all of those times vary from person to person. The numbers below are the ones studies describe, and I do not use any of them as a promise.

Part of the planHow it worksDuration described in studiesWhat makes it vary
Botulinum toxinRelaxes the muscles that mark expression linesThe effect appears in the first few days, peaks between 1 and 4 weeks and wears off in 3 to 4 monthsEach person's muscles and the dose
Hyaluronic acid fillerRestores volume and supportGenerally 6 to 18 monthsThe type of product, the area, the depth and the amount
Collagen biostimulatorMakes the body produce collagen graduallyWith poly-L-lactic acid, up to about 2 years after the sessions are completed. With calcium hydroxylapatite, about 15 months, on averageThe type of product, the number of sessions and each body's response

Microfocused ultrasound and skin care are also part of many plans. For those I prefer not to quote a number, because the interval between sessions depends on what the skin shows at each follow-up visit.

Why duration changes from one person to another

The timeframes in the table are ranges, and there is a reason they are wide. With hyaluronic acid, duration depends on how the gel is manufactured and also on where it is placed. In a report published in 2022, MRI scans still showed hyaluronic acid on the sides and in the middle of the face 27 months after the application, while in the chin, which moves more, it was almost entirely degraded at 19 months. It is a report of a single patient, but it helps explain why two areas of the same face may need a touch-up at different times.

With botulinum toxin, each person's muscles weigh in. With a biostimulator, the result is only complete after a few sessions, and that is when the clock starts. That is why I do not work with the same calendar for everyone.

What maintenance looks like

Harmonization is not something to rush, and maintenance does not need to be done all at once either. Since each part of the plan lasts a different time, what I do at the follow-up visits is look at the face again and treat only what needs attention at that moment. In many cases, that means renewing botulinum toxin a few times a year and leaving filler and biostimulator for longer intervals.

I follow patients over years, and what I see is that caring for yourself with planning and consistency counts for more than doing a lot in a single session. I also do not add new product without considering what is still in the face. The goal is to age well, preserving your features and your expression, not to look a different age.

Risks and who needs to wait

No part of a full face is free of risk. Swelling, redness, tenderness and small bruises are the most common effects and usually improve within days or weeks. With fillers, infection and nodules are less common, and the complication of greatest concern is accidental injection into a blood vessel, which is rare and can be serious. That is why the application must be performed by a qualified practitioner, and the follow-up visit is part of the treatment.

There are also people who need to postpone. Pregnant women, breastfeeding women and people with an active infection or inflammation in the area do not have the procedure at that time. Allergies, medical conditions and regular medication must be reported at the in-person consultation, which is when I confirm whether a full face makes sense for you and where to start.

Frequently asked questions

How long does the effect of a full face last?

There is no single timeframe, because full face is a set of procedures. In studies, botulinum toxin lasts 3 to 4 months, hyaluronic acid filler usually lasts 6 to 18 months and poly-L-lactic acid biostimulator can reach about 2 years after the sessions. These timeframes vary from person to person.

Is a full face done in a single session?

It depends on the plan. In some cases I combine more than one procedure in the same session, and in others the treatment is divided into stages, with an interval between them. That is decided at the in-person consultation.

Is full face just filler?

No. Hyaluronic acid filler is one part of the plan. In Full Face 3D I also consider botulinum toxin, collagen biostimulator, microfocused ultrasound and skin care, according to what each layer of the face needs.

How much does a full face cost?

There is no single price, because full face is not a fixed package. The plan changes from one face to another, and the price is only shared after the in-person consultation, when I know what makes sense to treat.

Want to know what would go into your full face?

At the in-person consultation, I look at your face in layers and explain what makes sense to treat, in what order and what to expect from each stage. I see patients in Aldeota, Fortaleza, and booking is via WhatsApp.
