Complications in Aesthetic Medicine: How to Prevent Them (and Act Safely)

Any aesthetic technique, no matter how simple it may seem, carries risks if not applied correctly. In this article, we discuss the most common complications in aesthetic medicine, how to prevent them from the initial patient assessment, and what to do in case of an emergency.

Complications in Aesthetic Medicine: How to Prevent Them (and Act Safely)

Complications in Aesthetic Medicine: How to Prevent Them (and Act Safely)

In aesthetic medicine, excellence is not only measured by visible results, but by the ability to prevent and manage complications.

According to Dr. Manuel Rubio, Medical Director of CIME Academy,

“The best aesthetic doctors are not those who never face a complication, but those who know how to detect it early and act with confidence.”

Below, we share the key pillars to prevent and manage emergencies in your aesthetic practice.

What are the most common complications in aesthetic medicine?

Among the most frequent are:

  • Hematomas and bruising
  • Persistent inflammation or post-injection nodules
  • Allergic or unexpected reactions
  • Vascular occlusions caused by hyaluronic acid
  • Infections at injection sites
  • Partial paralysis due to poor botulinum toxin application

Most of these can be prevented with proper patient assessment, precise anatomical planning, and correct technique.

Prevention First: 5 Essential Keys

  1. Know your patient’s medical history
    Never underestimate a thorough anamnesis. Allergies, anticoagulant use, autoimmune diseases, or previous treatments can all influence the outcome of the procedure.
  2. Choose the right technique and product
    Not all hyaluronic acids are the same, and not every area allows for the same techniques. Understanding product rheology and adapting it to the anatomical plane is essential.
  3. Respect anatomy and risk zones
    Accidents often occur due to lack of anatomical knowledge or overconfidence. At CIME, we teach doctors to master safe injection planes and identify high-risk vascular areas to avoid.
  4. Always have an emergency kit available
    Preparation makes the difference. Hyaluronidase, adrenaline, corticosteroids, antihistamines, topical antibiotics, and cold compresses should always be on hand.
  5. Continuous training and emergency simulation
    Knowing how to act in an emergency cannot be improvised. In our courses, we train doctors through real-life simulations and step-by-step analysis of emergency protocols.

And if a complication occurs? Act quickly and with clinical judgment

At the first warning signs — intense pain, color changes, loss of sensitivity, or early necrosis — time is critical.

Dr. Rubio emphasizes following a clear protocol:

  1. Early detection of symptoms
  2. Immediate suspension of treatment
  3. Application of pharmacological or physical measures
  4. Clinical and photographic documentation of the case
  5. Close patient follow-up

Safety does not mean avoiding all risks — it means knowing what to do and when to do it.

Training Makes the Difference

At CIME Academy, we’ve seen many doctors improve not only their aesthetic techniques but also their professional peace of mind.
Knowing that you can handle an emergency changes the way you approach every case.

Our training includes:

  • Complete modules on complications and emergencies
  • Real-case simulations and clinical analysis
  • Hands-on practice with real model patients and post-course mentoring

Do you want to perform aesthetic treatments with total safety and know how to act in any situation?

Why is Botulinum Toxin the ideal gateway to Aesthetic Medicine?

If you're a physician considering entering the world of aesthetic medicine, botulinum toxin is the best place to start. Due to its safety, high demand, and profitability, it represents a great opportunity to begin offering effective treatments from day one.

What is more convenient for me to do: a Fellowship or a specific course of Aesthetic Medicine treatment?

we develop a training for doctors by conducting practical courses with real patients. All of us who have completed a master's degree in aesthetic medicine know that the training we are given in the master's degree is much more theoretical than practical, which creates a big barrier for us when we ha
