Regenerative biostimulation: trend and caution

Every year, facial harmonization gains new vocabulary. "Regenerative biostimulation" is one of the terms that has grown the most at congresses, in ads and in hallway conversations. It sounds technical, promises something different from "filling" and attracts patients who want better skin, not just volume. The problem is that a market label is not a scientific category. This guide helps you separate what the term usually covers, what is known and not known, and how to indicate it with caution. Products, techniques and decisions rest with the licensed professional, according to the package insert and the rules of their professional council.

What the term usually covers

There is no single definition. In practice, "regenerative biostimulation" is used to group approaches that, in theory, stimulate tissue responses, such as collagen production, better hydration and skin quality. Among them you will usually find:

• Collagen biostimulators, a category of injectables that induce a tissue response. See biostimulators: overview and collagen biostimulator.
• Polynucleotides, covered in polynucleotides in facial harmonization.
• Skin boosters, deep hydration with hyaluronic acid, compared in skin booster vs. polynucleotides.
• Microneedling combined with active ingredients, addressed in microneedling with biostimulator or hyaluronic acid.
• Other technologies, such as light and ultrasound, which the clinic may combine. See ultrasound in facial harmonization and post-procedure photobiomodulation.

Each of these fronts has its own profile of evidence, regulation and risk. Using the label without naming what will be done is the gateway to vague promises.

Why the term grew

A few trends explain its popularity:

1. Change in what patients ask for: patients look for naturalness and skin quality, more than volume.
2. Product variety: new molecules and combinations appear quickly.
3. Marketing: the word "regenerate" carries emotional appeal.
4. Patient profile: a "rested" face, "alive" skin and firmness are frequent requests.
5. Combination protocols: combining techniques is common in practice.

These trends are not bad. The problem is when the appeal of the word replaces the assessment.

What can and cannot be promised

Communication needs to be honest about limits.

In advertising, the rules apply: see what you may advertise and check your professional council's rules. Before and after images must follow the regulations and the patient's consent.

Risks and precautions

Every injectable product carries risks, and biostimulators have a profile of their own.

• Nodules and irregularities, which can appear late. See nodules after biostimulator.
• Swelling and bruising, expected to some degree.
• Infection, including late infection, and inflammatory reactions.
• Unpredictable response, with differences between patients.
• Difficulty reversing, since some products have no specific antidote.
• Vascular risk, depending on the area and the technique.

The overview is in complications with biostimulators and safety and complications: overview. A useful rule: the lower the chance of reversing, the greater the rigor of the indication and the consent.

How to decide whether to indicate it

A short checklist prevents following a trend on impulse.

Not every new treatment deserves to be dismissed, and not every one deserves enthusiasm. The professional who documents the decision and follows up on the result builds their own data to assess what works in their clinic.

How to explain it to the patient

Avoid the adjectives "miraculous," "definitive" and "natural with no risks." A well-informed patient decides better and comes back with confidence.

Record and consent

Note the product, the manufacturer, the lot, the technique, the area, the volume and the agreed expectation. The informed consent should state the type of product, the complications and the possibility of a result different from what was expected. If the use is off-label, follow the rules for off-label use. Record keeping is covered in patient records and documentation in facial harmonization.

Common mistakes

1. Adopting the term without knowing what is being applied. Naming the product, technique and purpose is the basis of consent.
2. Buying a technique from a talk. Congress enthusiasm does not replace supervised training.
3. Promising regeneration or rejuvenation. These are claims the evidence does not support and advertising rules restrict.
4. Combining many treatments at once. When something goes wrong, it is hard to know the cause.
5. Not following up. Without standardized photos and follow-up visits, there is no way to know whether the technique works in your practice.

How to follow up in practice

Standardize the before and follow-up photos, with the same lighting and position. Schedule follow-up visits at intervals consistent with the gradual response of these treatments, at the professional's discretion. Record what was applied, in which areas and with which product. Ask the patient how they rate the result, without leading them. With this discipline, your clinic produces its own data, and the decision to keep, adjust or abandon a trend rests on what you observed, and not just on what was said on a stage.
