Laser hair removal targets the pigment in each hair follicle with precise pulses of light, heating and disabling it so hair grows back finer and sparser over a course of sessions. No more shaving, stubble, ingrown hairs or deodorant irritation on freshly shaved skin.
Because the underarm is such a small area, each session takes around 30 minutes. Every treatment is carried out personally by our specialist in a private Chelsea studio — never handed to a junior — using medical-grade laser technology suited to a wide range of skin tones. Results vary from person to person, which is why we start with a free patch test.
Tap the button, pick a time that suits you, and book securely online.
A quick, free test 24–48h before sets your safe laser settings. Required before any first treatment.
30 minutes, minimal discomfort, and you’re straight back to your day.
Prefer to start with just the free patch test? Book that here.
Your £20 first session is a no-obligation way to try laser and meet us. We’ll talk you through your options and a personal plan afterwards — but there’s never any pressure to book a course. Free patch test included, with secure online booking.
New clients trying us for the first time — one £20 underarm session per person. It lets you experience the treatment and our studio before deciding on a course.
Most people describe the underarm as a warm elastic-band flick. It’s a quick area and our cooling system keeps it comfortable. Sensations vary from person to person.
Hair grows in cycles, so a course spaced a few weeks apart gives the best lasting hair reduction. Your £20 session is a no-commitment way to start.
A patch test 24–48h before confirms the safest, most effective settings for your skin. It’s free, quick, and included with your offer.
We use medical-grade laser, not IPL. Laser targets a wide range of skin tones and hair types.
