Undo PMU Laser Removal Training UK

Why Undo PMU® Was Created

With more than 26 years in the skin and beauty industry, Cheryl Booth has dedicated her career to helping practitioners deliver safer, more confident permanent makeup removal treatments.

After years of performing corrective treatments and laser removal, she recognised a growing need for education that focused on consultation, skin assessment, pigment behaviour and clinical decision-making, not simply operating a laser.

That belief became Undo PMU®, a specialist training academy dedicated to raising professional standards in permanent makeup removal, laser tattoo removal and laser education throughout the UK.

Today, practitioners from across the UK choose our professional laser removal training to develop practical skills, clinical confidence and a deeper understanding of the complete laser PMU removal process long after the course has finished.

The Five Principles Behind Undo PMU®

Rather than simply teaching laser settings, Cheryl has built Undo PMU® around five principles that shape every treatment, every consultation and every training course.

Assessment First

Every treatment begins with a thorough consultation, creating safe, personalised treatment plans tailored to every individual client.

Clinical Judgement

Every practitioner learns to assess, adapt and make informed decisions rather than relying on pre-set laser settings.

Safety Without Compromise

Every treatment begins with understanding skin, pigment, contraindications and safe clinical practice before every procedure.

Honest Education

Every practitioner receives clear guidance, realistic expectations and practical knowledge to build lasting confidence and client trust.

Support Beyond Training

Every practitioner receives ongoing guidance, mentoring and support long after completing their laser training.

Why Practitioners Choose Cheryl Booth

Practitioners don’t simply train with Cheryl to learn laser removal. They choose Undo PMU® because they value honest education, practical experience and ongoing support from someone who continues to perform real treatments, solve complex cases and help raise professional standards across the UK.

Teaching the Thinking, Not Just the Settings

One phrase sits at the heart of every Undo PMU® course.

“Learn the thinking, not just the settings.”

  • Every client is different

  • Every pigment behaves differently

  • Every treatment requires professional judgement

Why is laser training so important to PMU artists

That’s why every course combines practical experience with consultation techniques, skin assessment, laser safety, contraindications and aftercare, helping practitioners feel confident when treating real clients. That philosophy begins with the recognised Laser Core of Knowledge, giving students the theoretical understanding of laser safety, wavelengths and tissue interaction before progressing to practical treatment training.

Putting Clients First

Everything Cheryl teaches begins with one simple principle.

The client always comes first. Whether that means proceeding with treatment or advising that laser removal isn’t yet the right option. This means:

  • Carrying out thorough consultations

  • Setting realistic expectations

  • Knowing when treatment should wait

  • Providing honest advice

Why is laser training so important to PMU artists

Creating personalised treatment plans based on the individual, not a standard protocol, is the approach that continues to build trust with both clients and practitioners throughout the UK.

Looking Ahead

Permanent makeup removal continues to evolve, and so does Cheryl’s commitment to education.

Through practical training, industry speaking, mentoring and the continued development of Undo PMU®, her goal remains the same:

  • Help practitioners deliver safer treatments

  • Help clients receive honest advice

  • Continue raising professional standards throughout the UK laser removal industry

As laser treatments continue to grow in popularity, many clinics are expanding into additional services such as laser hair removal. Read our guide to whether laser hair removal training is worth it.

The Undo PMU® Philosophy

Technology evolves… Lasers improve… Treatments change.

But one thing remains the same.

Professional laser removal will always depend on knowledge, clinical judgement and putting the client first.

That’s the philosophy Cheryl has built Undo PMU® upon, and the standard she continues to pass on to every practitioner who trains with her.

  • Because great laser practitioners aren’t defined by the laser they use, they’re defined by the decisions they make before treatment even begins.
