The how-to
Using numbing cream
How you apply numbing cream, how long you leave it on, and how long the comfort lasts all depend on the product, the area and your appointment — here's how to think about each, and why your practitioner's guidance comes first.
The honest answer
What numbing cream does — and what comes first
Numbing cream is a topical cosmetic preparation applied to clean skin before a treatment to support comfort. It is not an anaesthetic and not a medicine. How long to leave it on varies by product and appointment — the product's own instructions and your practitioner's advice always come first. Many clinics apply their own as standard, so check before bringing yours.
The routine, in one line each — Clean, dry skin → a generous, visible layer, never rubbed in → covered only if your practitioner advises → removed fully before treatment.
Before first use
First time with any product? Patch test 24 hours ahead — a small amount on the inner wrist or behind the ear. If your skin reacts, don't use it, wash the area, and seek medical advice if the reaction continues.
How long to leave it on
The label is the authority
Leave numbing cream on only for the time the product's instructions specify. Longer isn't better and can irritate the skin. Because products differ, there's no single number that fits all — the label is the authority, and your practitioner can confirm what suits your treatment.
Timing
Timing depends on your appointment
How long the comfort lasts varies by product, area, and how it was applied — so plan around your appointment time and your practitioner's guidance rather than a fixed figure. If you're timing application before a clinic visit, ask them when they'd like it applied.
