Immersion in Fractional CO2 Laser

Target Audience

Undergraduates in aesthetic biomedicine, dentistry, medicine, and aesthetic pharmacy.
Undergraduates from the 6th semester of biomedicine, dentistry, and medicine.
Students in advanced aesthetics specialization.

Course offering justification - The fractional CO₂ laser is one of the most established and sought-after technologies in skin rejuvenation, addressing photoaging, wrinkles, mild laxity, acne scars, dyschromias, and texture and pore refinement. As it is an ablative procedure, it requires the professional to have a rigorous technical mastery of parameters, an understanding of the laser-tissue interaction, and careful management of the risk of post-inflammatory hyperpigmentation (PIH), especially in higher phototypes. The aim of this course is to train aesthetic health professionals to operate safely, based on scientific foundations and predictable results, while respecting biosafety and the individuality of each phototype.

General Objective

To train professionals to perform resurfacing and rejuvenation procedures with fractional CO₂ laser safely, based on scientific principles, while respecting biosafety standards and managing pigment risk, aiming for harmonious and predictable aesthetic results.

Specific Objectives

• To present the fundamentals of laser physics and laser-tissue interaction (water chromophore, ablation, and coagulation).
• To understand fractional technology and the concept of treatment zones (DOT/microcolumns).
• To teach the reading and adjustment of parameters: power, pulse duration, energy, DOT (spacing), repetitions, interval, and delay time.
• To master pre-procedure evaluation, patient selection, and screening.
• To understand skin preparation and the depigmenting protocol before and after the procedure.
• To prevent and manage complications, paying attention to the risk window for PIH (weeks 3 to 8).
• To understand the appropriate topical anesthesia modalities for the procedure.
• To develop communication skills for a humanized service and alignment of expectations.

Graduate Profile

Graduates will be able to work in aesthetic clinics, private practices, facial harmonization and rejuvenation centers, provided they comply with the regulations of their professional category and hold registration with the regional council, allowing them to practice without supervision.
