Asepsis and antisepsis in facial harmonization: the difference
Asepsis is the set of measures that prevents microorganisms from entering a place where they are not present. Antisepsis is the reduction or elimination of microorganisms from living tissue, such as the skin, with the use of antiseptics. In the practice of facial harmonization (known in Brazil as HOF, orofacial harmonization), the two go together and are the basis of infection prevention.
What is the difference in practice?
| Term | What it is | Example in facial harmonization |
|---|---|---|
| Asepsis | Avoiding contamination | Sterile, single-use material, clean field |
| Antisepsis | Reducing microbes on skin or mucosa | Cleaning the skin with antiseptic before the puncture |
| Disinfection | Reducing microbes on surfaces and objects | Countertop, chair, equipment |
| Sterilization | Eliminating all forms of microbial life | Reusable instruments in an autoclave |
Why does it matter so much in injectable procedures?
Each puncture is a point of entry. Bacteria carried into the tissue along with the product can cause an early infection or organize into biofilm, with nodules and inflammation weeks or months later. These conditions tend to be hard to treat, which is why prevention weighs so heavily.
What precautions usually form part of it?
- Remove makeup and cream residue before antisepsis.
- Sanitize the hands and wear gloves.
- Use sterile, single-use needles and cannulas, changing them when necessary.
- Avoid touching the prepared area and the tip of the instrument.
- Do not inject over an active lesion, such as herpes or inflamed acne.
Protocols and products follow health regulations and the rules of the professional council in Brazil. The topic also appears in safety and complications.
