Safety and Sanitation
Core Concepts
Infection control follows a hierarchy: cleaning removes visible debris; disinfection destroys most pathogenic microorganisms on nonporous surfaces; sterilization destroys all microbial life, including spores. Estheticians typically clean and then disinfect implements with an EPA-registered hospital-grade, tuberculocidal disinfectant, following the label contact time. Porous items-sponges, wooden sticks, cotton, and some files-cannot be reliably disinfected and must be single-use or discarded. Implements must be cleaned before disinfection because debris shields microbes.
Know standard precautions: treat all blood and body fluids as infectious. Wash hands before and after service, wear gloves when contact with blood, body fluids, or non-intact skin is possible, and use PPE. Bloodborne pathogen training, SDS access, and local licensing rules apply. Disinfect bottles, tables, and tools between clients, and store clean and dirty items separately. Never double-dip. Use covered waste for blood-contaminated materials and report exposures per protocol.
Contraindications and patch tests protect clients: active infection, open lesions, recent surgery, allergic reactions, and certain medications may require postponement or referral. Keep accurate records, informed consent, and notes about products used.
Traps
A frequent trap is confusing disinfection with sterilization, or skipping cleaning before disinfecting. Another is assuming a porous nail file can be disinfected. Questions may also test whether to use a towel to stop bleeding-use gloves and proper first aid, not bare hands.
Rule of Thumb
Clean first, then disinfect for the full label contact time. If an item cannot be cleaned and disinfected, use it once and discard it.
