What microneedling is and how it works on the skin

Microneedling involves creating controlled micro-perforations in the skin with fine needles. These are minimal, superficial and orderly injuries that the skin reads as a repair signal.

That signal triggers collagen and elastin production, the two proteins that sustain skin firmness and elasticity. Unlike a treatment that fills or adds volume from the outside, here the result comes from the patient's own tissue.

This is why microneedling is classified as a collagen induction procedure. Its field of action is quality and texture: acne scars, enlarged pores and an uneven skin surface. In well-selected patients, the skin tends to look more even and better in texture as the remodeling process advances. If the logic of stimulating your own collagen interests you, you can read Biostimulators: less filler, more of your own collagen.

Who it is indicated for and who it is not

Microneedling is usually considered for patients who consult about acne scars, enlarged pores or skin with compromised texture and firmness. It is a treatment that works on skin quality, not on facial volumes.

It is often a good option

  • When marks and scars remain after an acne process.
  • When enlarged pores are the main reason for the consultation.
  • When the skin feels rough, uneven or lacking firmness.
  • When the goal is prevention and maintenance of skin quality.

It requires closer evaluation

If there is active acne, infection or lesions in the area, healing disorders, or medical conditions that may interfere with skin repair, Dr. Sandro Florez evaluates each case and decides whether the timing is right or whether another route is preferable. That decision is made during the assessment, not from a catalog.

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

Initial assessment

Everything begins with a medical consultation in Bogotá. The medical history, the current condition of the skin, the type of scar and the patient's expected outcome are all reviewed. From there come the plan and the suggested number of sessions, which varies from case to case.

Preparation and application

On the day of the procedure the area is cleansed and the skin is prepared. The controlled micro-perforations are then performed, covering the treated area in an orderly way and adapting the technique to the zone and to the goal defined during the assessment. Session length depends on the area and on each patient's plan; the physician estimates it during the consultation.

Afterwards

Aftercare instructions are given in writing and the follow-up visit is scheduled. Follow-up is part of the treatment: it allows the plan to be adjusted according to how the skin responds.

Results: what to expect and when

Microneedling does not produce an immediate change, because its mechanism depends on a biological process. The skin needs time to form new collagen and elastin after the stimulus, so changes appear progressively.

In well-selected patients, what is usually observed is a gradual improvement in texture, a more even appearance of enlarged pores and a softening of acne scars. The extent of the change varies: it depends on the type and depth of the scar, how old the lesion is, the skin type and each patient's individual response.

For this reason no result can be guaranteed or promised within a fixed number of sessions. The sensible approach is to set realistic goals during the assessment, work in stages and evaluate the response at follow-up visits. Dr. Sandro Florez adjusts the plan based on that clinical evidence, not on a protocol identical for everyone.

Aftercare and recovery

Microneedling is an in-office procedure. As with most facial treatments, it usually allows patients to resume their routine the same day, with the caveat that the skin is left sensitive and may show redness or mild swelling during the first hours or days, depending on each patient.

General recommendations

  • Keep the skin clean and use only the products the physician indicates.
  • Apply sun protection strictly and avoid direct exposure while the skin recovers.
  • Avoid makeup, exfoliants and irritating actives until medically cleared.
  • Do not manipulate or scratch the treated area.
  • Seek advice if intense pain, signs of infection or any unexpected course appears.

The exact instructions and the duration of each restriction are defined by the physician during the assessment, because they depend on the treated area and the technique used.

Why have it done by a physician in Bogotá

Even though microneedling is described as a straightforward procedure, it remains a medical act: it involves crossing the skin barrier. That requires prior diagnosis, aseptic conditions, appropriate materials and the judgment to decide depth, zones and frequency.

That judgment is precisely what separates a carefully handled result from an avoidable complication. Not all acne scars respond the same way, nor do all skin types tolerate the same approach. Skin prone to pigmentation, for example, calls for different decisions than skin that is not.

Dr. Sandro Florez, a physician and surgeon devoted to aesthetic medicine, sees patients in Bogotá at Calle 126 # 7-26, Torre 126 PH-1303. There the indication is built case by case, with a written plan, follow-up visits and the option to rethink the approach if the skin responds differently than expected.

Combining it with other treatments

Microneedling is rarely considered in isolation. It usually fits into a broader facial plan in which each procedure contributes something different: some work on skin quality and luminosity, others on firmness, and others on volumes or expression.

Within an anti-aging approach, the combination and the order of procedures are defined by the physician during the assessment, because they depend on the diagnosis, the condition of the skin and the recovery times of each technique. There is no single formula or standard package.
