For years, the answer to facial aging was to add volume. Today the global trend is moving in the opposite direction: stimulating the body itself to recover what it has lost. That is the promise of collagen biostimulators, and it explains why 85% of today's patients ask for natural, subtle results.
Why the approach changed
Until recently, when a face looked tired the almost automatic solution was to fill. The problem is that time does not only subtract volume: it also affects the firmness and support of the skin. Filling tissue that has lost structure may correct a shadow, but it does not restore the quality of that tissue. That is why, at the practice of Dr. Sandro Florez in Bogotá, more and more patients arrive with a different request: they do not want to look «done», they want to look rested.
That shift in mindset explains the rise of biostimulation. Instead of occupying a space, the idea is to give the tissue a signal so it goes to work. It is a more patient approach and, for that very reason, a more discreet one.
How do they work?
Substances such as calcium hydroxyapatite (CaHa) or poly-L-lactic acid do not fill: they activate. When applied in the appropriate planes, they wake up the fibroblasts so that they produce new collagen and elastin. The result builds up gradually over weeks: firmer skin, better support and a rested face, without anyone knowing what you had done.
The key word is gradual. Unlike a procedure whose effect is visible as you walk out of the office, here what is applied is a stimulus and what is seen afterwards is the body's own response. That is why two people with a similar indication may progress differently: the response depends on the skin, the age, the habits and the general condition of each patient.
It is also why the plane of application matters as much as the product. Each area of the face and body has a plane where the stimulus is appropriate and others where it is not advisable. That decision is strictly medical, and it is one of the reasons why this type of treatment should be performed in a clinical setting and after a proper assessment.
How are they different from hyaluronic acid?
Hyaluronic acid provides immediate volume and hydration and remains irreplaceable for harmonizing features. Biostimulators work over the longer term on the structural quality of the skin. In modern practice they are usually combined: small doses of filler where they are needed, biostimulation where the skin is asking for firmness.
Seeing them as rivals is a common mistake. They answer different questions: one addresses shape, the other works on support. In an anti-aging medicine consultation, the usual task is not to choose between them, but to define in what proportion and in what order they should be used.
Areas where they shine
The face (especially the lower third and the jawline), neck, décolleté, hands and even buttocks and arms in body protocols. They are also a great ally for skin that has lost support after significant weight loss.
In facial treatments, the lower third and the jawline are usually the areas where the change is perceived most clearly, because that is where the loss of support shows up first. In body protocols the goal is different: the aim is to support firmness and texture over wider areas, with a plan that almost always involves several sessions.
Who they are for, and who they are not for
Usually good candidates
- People who notice a loss of firmness and support rather than a specific lack of volume.
- Those looking for a gradual, discreet change, with no obvious before and after.
- Patients willing to think in terms of a medium-term plan rather than an immediate solution.
- Skin that has lost support after significant weight loss.
- Those who already use hyaluronic acid and also want to work on the quality of the skin.
Cases where it is better to wait or review first
- Pregnancy and breastfeeding.
- Active infection or a lesion in the area to be treated.
- Autoimmune conditions, healing disorders or medications the doctor needs to review beforehand.
- A history of reaction to any of the components.
- Expecting an immediate result or a radical transformation of the face.
This list is a guide, but it does not replace the assessment: there are findings that only come out by talking and examining the skin.
How it is done in the office
Everything starts with the assessment. The medical history, medications, previous procedures and, above all, what the patient expects are reviewed. Dr. Sandro Florez examines the skin, defines the areas, the product and the number of sessions, and explains what it is reasonable to expect in each case.
On the day of the procedure, the areas are cleansed and marked, aseptic measures are applied along with the comfort measures the doctor considers appropriate for each patient. The product is then applied in the defined planes and, when the protocol calls for it, a subsequent massage is performed to distribute it.
It is an outpatient procedure: it is carried out in the office and the patient walks out afterwards. Most people return to their routine the same day or the next, with whatever restrictions the doctor indicates.
What to expect
In the first few days there may be redness, mild swelling, tenderness or some bruising at the entry points. These are expected findings and usually resolve on their own.
The result, on the other hand, does not appear overnight: it builds over weeks as the body responds. In well-selected patients it is usually noticed first as a comment from those around you along the lines of «you look rested», rather than as an obvious change in the mirror.
More than one session may be required. How many and how far apart is a decision the doctor makes during the assessment, not a fixed figure. And the effect is not permanent either: how long it lasts varies according to each patient, their skin and their habits, so at some point maintenance is usually discussed.
Aftercare
- Follow the massage instructions to the letter, if the doctor gave any.
- Avoid direct sun exposure and use sunscreen daily.
- Postpone sauna, steam room, intense exercise and local heat for as long as the doctor indicates.
- Do not massage or apply strong pressure to the area on your own initiative.
- Take care of hydration, sleep and habits: the collagen is produced by your own body.
- Seek advice if you have increasing pain, persistent color changes, nodules or any unexpected sign.
When it is not the best option
Biostimulators do not solve everything. When there is very advanced laxity or excess skin, the honest answer is that the path may be surgical rather than injectable; in those cases the conversation turns towards plastic surgery. If what is missing is shape or projection at a specific point, hyaluronic acid responds better to that need. And if the main concern is pigmentation, texture or acne, there are other tools within the treatments menu that address that problem more directly.
Nor is it the best choice for someone who needs a change for an event a few days away or is not willing to wait weeks. In that scenario, insisting on biostimulation usually ends in frustration.
The key is the plan
Biostimulation is not an event, it is a process: during the assessment we define how many sessions, which product and which combination suits your skin and your age. The goal is always the same: that you look better, not different.
If you are in Bogotá and want to know whether you are a candidate, you can book an assessment and review your case calmly before deciding.
