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
Topical numbing cream is applied to clean skin before a treatment to make it more comfortable. It's a cosmetic preparation, not an anaesthetic. How long to leave it on, and how long the effect lasts, vary by product, by the area, and by how much is applied, so the product's own instructions and your practitioner's advice always come first. Many clinics apply their own numbing as standard, so it's worth checking before you bring your own.
Application
How to use it
A patch test comes first — about 24 hours before your first use, apply a small amount to your inner wrist or behind the ear and check for any reaction. Don't use it if your skin reacts.
-
Start with clean, dry skin.
Begin on clean, dry skin before you apply anything.
-
Apply an even layer.
Apply an even layer to the area being treated — follow the amount the product specifies.
-
Allow time before your appointment.
Many customers tell us they get their best results applying cream around 45–60 minutes before their appointment, though this varies from person to person. Follow the product's instructions and your practitioner's advice (gel and spray: allow time to take effect).
-
Cover the area if advised.
If your practitioner advises, cover the area — for example with cling film — while it takes effect.
-
Leave it on as directed.
Leave it on for the time stated in the product's instructions (don't guess, and don't leave it longer to "boost" it).
-
Remove it cleanly before treatment.
Remove it cleanly before your treatment begins, unless your practitioner tells you otherwise.
When in doubt, ask your practitioner first — many prefer to advise on what you use and how.
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.
How long it lasts
How long it lasts
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.
