What biostimulators are and how they work

Calcium hydroxyapatite and poly-L-lactic acid belong to the family of collagen biostimulators. Their role is not to occupy space or create artificial volume, but to generate a controlled stimulus in the skin so that the body itself responds by producing new collagen.

That collagen is what provides firmness and support, two qualities the skin gradually loses over time. As the supporting structure rebuilds, the skin tends to look denser and of better quality, with an improvement that becomes noticeable progressively on the face and neck.

This is a different approach from a traditional filler, as we explain in the article Biostimulators: less filler, more of your own collagen. The choice between one product and another, as well as the areas to treat, is made by the physician based on what is found during the consultation.

Who they are indicated for, and who they are not

Biostimulators are usually considered for patients with mild to moderate laxity who are looking for firmness, support, and collagen stimulation on the face and neck. They work well when the goal is to improve skin quality progressively, without transforming facial features.

They are not the answer for everything. If the predominant concern is significant volume loss, advanced laxity, or an expectation of immediate change, the physician may suggest other paths within facial treatments, or even guide you toward plastic surgery.

Nor is this a treatment chosen from a catalog. Medical history, medications, skin conditions, and previous procedures can all change the indication. That is why Dr. Sandro Florez evaluates each case before proposing a plan.

What the procedure is like at Dr. Sandro Florez's practice

Everything begins with a medical consultation at the Bogotá office, located at Calle 126 # 7-26, Torre 126 PH-1303. There, your skin is examined, your goals are discussed, and it is determined whether calcium hydroxyapatite, poly-L-lactic acid, or a combination with other treatments is the most appropriate option.

Application

Once the plan is defined, the application is an in-office procedure performed by the physician at the points and planes determined during the consultation. The number of sessions and the amount of product are not standard: they depend on each patient's skin and on the agreed goals.

The length of the appointment and the intervals between sessions are also defined by the physician during the consultation, since they vary from case to case. You can book your appointment to address these questions in person.

Results: what to expect and when

The result of a biostimulator is progressive. Because the change depends on your skin producing new collagen, this is not an effect that appears overnight, but an improvement that becomes visible over time.

In well-selected patients, skin usually appears to have greater firmness and support, along with better overall quality on the face and neck. What is not sought is to change your expression or your features: the goal is for the skin to look better supported, not different.

No aesthetic treatment guarantees an identical result in every person. Individual response varies with age, skin quality, habits, and starting condition. During the consultation, the physician will explain what is reasonable to expect in your specific case.

Aftercare and recovery

Biostimulators are applied in-office and, like most injectable facial procedures, do not usually require time off. There may be mild redness or swelling in the hours that follow, which is expected and temporary.

Aftercare recommendations are part of the treatment and are given by the physician according to what was performed. They often include guidance such as:

  • Following instructions about handling or massaging the area, if the physician provides them.
  • Caring for the skin with daily sun protection.
  • Reaching out about any discomfort that does not subside or that raises questions.
  • Attending the follow-up visits indicated to assess your progress.

Every patient receives specific instructions: they are not the same for everyone, which is why it is best to follow those explained to you by Dr. Sandro Florez rather than what circulates on social media.

Why have it done by a physician in Bogotá

A biostimulator is not a product applied the same way on every face. Knowing which areas to treat, in which plane, and with which product requires knowledge of facial anatomy and aesthetic judgment, and only a physician who evaluates your case can provide that.

Dr. Sandro Florez is a physician and surgeon with experience in aesthetic and hair medicine, seeing patients at his Bogotá office. His track record with injectables has been recognized by the industry, as described in this article about the Allergan Aesthetics recognition.

Safety begins with an honest assessment: understanding your history, reviewing whether the treatment is truly right for you, and telling you when it is not. Personalizing also means knowing when to propose a different alternative.

Combining with other treatments

Biostimulators rarely work alone. Within a comprehensive facial plan, they can be combined with other procedures that address different aspects of aging, always following the sequence and timing the physician determines.

  • Anti-aging treatments focused on prevention and medical skin care.
  • Other facial treatments aimed at texture, radiance, or harmonizing features.
  • Regenerative alternatives such as polynucleotides, which work through a different mechanism than biostimulators.

What is combined, in what order, and how far apart is a medical decision. You can review the full picture in the treatments section and address specific questions during your consultation.
