Application

How to apply numbing cream, step by step.

Cream, gel and spray each have their own routine — the layer, the covering, the window, the removal. This is the complete guide.

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.

Start with clean, dry skin.
Cleanse the treatment area — the Foaming Cleanser or any mild, non-stripping cleanser — and pat fully dry. The layer needs direct contact with clean skin; anything left on the surface gets in the way.
Apply a generous, visible layer.
Around 2–3mm — enough that it sits visibly on the skin. Cover the whole treatment area. Don't rub it in; the layer should rest on the surface, not disappear into it.
Cover with cling film.
It keeps the layer in place and in contact with the skin. Seal the edges. If your practitioner prefers the area uncovered, their instruction wins.
Leave it in place for the full window.
As a general guide, allow 45–60 minutes between applying and your appointment. If your practitioner has set a window, theirs is the number that counts.
Remove it fully just before treatment.
Wipe clean with a clean cloth or tissue — many practitioners prefer to do this themselves at the chair. Tell them in advance that you've applied numbing cream; some adjust their skin prep when it's been used.

Choose your format

Gel

The targeted routine.

Same five steps as cream, one difference: gel suits smaller, more precise zones — lips, brows, compact treatment areas. Apply where the work is happening rather than broadly, keep the same generous visible layer, and cover if your window is longer.

Start with clean, dry skin.
Same starting point. Pat dry.
Spray an even coverage from 10–15cm.
2–3 short bursts per area, a moment to settle, then top up only where coverage is thin. Spray goes further than cream — stop at full, even coverage.
Leave it in place for the window.
Spray suits body procedures — waxing, laser, larger zones. The same general guide applies; work to your practitioner's protocol where they've set one.
Remove it fully before your appointment.
Clean cloth or tissue, at their instruction.

By procedure

A few procedure-specific notes.

Your practitioner is the source of truth for timing and protocol. These are the brand's general observations.

Lip Fillers. A small treatment area. Less product than a microneedling appointment. Most practitioners have a specific timing window — ask in advance.

Botox. The shortest procedure in the aesthetic catalogue. Some clients skip numbing entirely. If you're using it, Clinical Strength suits most appointments.

Microneedling. Longer session, broader treatment area. More product, longer prep window typically required. Advanced Strength is the usual recommendation.

Laser. Treatment area decides the format. Cream for face zones. Spray for body. Confirm your practitioner's protocol before applying.

SPMU (Microblading, Lip Blush). Sustained sittings. Some artists reapply during the session. Most have specific guidance on what to bring and when to apply.

Waxing. Body procedures suit spray. Smaller zones (lip, brow) suit cream. Bikini and brazilian appointments often benefit from longer prep windows than face appointments.

What to avoid

Three application mistakes that come up.

Rubbing it in. The layer should sit visibly on the skin — even and unrubbed.

Applying too thin. A layer you can't see is a layer that's short. 2–3mm, whole area.

Cutting the window fine. Applying in the car park isn't a window. Allow the full window before your appointment.

Skipping the removal. The product should be fully off the skin before work starts.

When to ask your practitioner

Specific timing windows vary widely by procedure, by clinic, and by individual sensitivity. Most aesthetic practitioners have application protocols they recommend to their clients — these are tested in their context, with their procedures, on the kind of bookings they actually run. Ask in advance. Most practitioners will tell you how long to leave the product on, whether to bring your own or use theirs, and what they prefer to do at the chair themselves.

Common questions.

How long before my appointment should I apply?

As a general guide, 45–60 minutes before. Procedures and practitioners vary — if yours has set a window, use theirs.

How much should I apply?

A generous, visible layer, around 2–3mm — covering the whole treatment area, sitting on the skin rather than rubbed into it.

Can I apply it the night before?

No. It's applied on the day, within the window before your appointment.

Should I cover the area with cling film or anything else?

Yes, unless your practitioner says otherwise — cling film with sealed edges keeps the layer in place.

What if I apply too early?

The window can pass before your appointment starts. If you're running early, ask your practitioner whether to reapply or wait.

Should I wash it off or wipe it off?

Most practitioners prefer wiping with a clean cloth or tissue. Some wash. Follow your practitioner's specific instruction.

Is this a medicine?

No. Senseless is a UK cosmetic product. Not a medicine. Not a pharmacy product.
