Question 1

Staphylococcus epidermidis is the leading cause of biofilm-related delayed inflammatory reactions around hyaluronic acid and other dermal fillers.

Question 2

What is the minimum contact time for a quaternary ammonium compound surface disinfectant to be effective in an aesthetics treatment room?

Accepted Answer

The manufacturer's stated dwell time (typically 3–10 minutes)

Answer

Disinfectants must remain wet on the surface for the manufacturer's specified dwell time — usually 3–10 minutes — to achieve the labeled kill claims.

Question 3

Under CDC hand hygiene guidelines, when is an alcohol-based hand rub (ABHR) NOT appropriate, requiring soap and water instead?

Accepted Answer

When hands are visibly soiled or contaminated with blood

Answer

Soap and water must be used when hands are visibly soiled or contaminated with blood or other body fluids, as ABHR is ineffective in those conditions.

In a refrigerator at 2–8°C and used within the manufacturer's specified window (typically 24 hours)

Answer

Reconstituted botulinum toxin must be refrigerated at 2–8°C and used within the manufacturer's stated timeframe, commonly 24 hours, to maintain potency and sterility.

Accepted Answer

Localized erythema, warmth, swelling, and pain beyond expected post-procedure response
