Acne Certification
About Course
Become the acne expert your clients have been looking for.
This is not a product training. This is not a brand day. This is a full clinical certification in the science, pathology, and treatment of acne, built specifically for skin therapists and aesthetic practitioners who want to treat this condition with real depth, real confidence, and real results.
Acne is one of the most complex and misunderstood skin conditions in clinical practice. It is also one of the most in demand. Yet most therapists tell us they still second guess themselves when a client sits in their chair with active breakouts, hormonal congestion, or post inflammatory hyperpigmentation that will not shift.
This certification changes that completely.
Built in partnership with leading dermatologists and developed from the ground up with clinical accuracy at its core, the Skin United Acne Specialist Certification takes you deep into the biology, the triggers, the treatment science, and the client journey — giving you everything you need to become the practitioner clients seek out specifically for their skin.
What you will learn:
The full biology of acne including follicular hyperkeratinisation, the inflammatory cascade, and the microbiome The hormonal picture in depth — PCOS, perimenopause, insulin resistance, the contraceptive pill, and how each drives acne differently The gut-skin axis and why internal health is inseparable from skin outcomes How to accurately assess, classify, and diagnose every acne presentation you will encounter in clinic Clinical treatment protocols built on mechanism and science, not habit or brand loyalty Homecare plans your clients will actually follow and why compliance drives results Post inflammatory hyperpigmentation — causes, prevention, and clinical treatment Acne in skin of colour — unique considerations, risks, and treatment adaptations The psychology of living with acne and how to consult with sensitivity and clinical authority How to build, price, and market acne programmes and position yourself as a specialist worth paying for
Course details:
85 units across 16 sections 16+ hours of clinical content Dermatologist-sourced throughout IPHM accredited — recognised by UK insurers Self paced with lifetime access Certificate of completion included
This certification does not just teach you about acne. It transforms the way you see skin, builds the clinical language to speak about it with authority, and gives you the tools to deliver results that genuinely change your clients lives.
The practitioners who complete this certification are charging between £2,000 and £6,000 for acne treatment programmes.
This is where that journey starts.
What Will You Learn?
- The clinical science behind acne formation — how and why acne develops at a cellular level, including the role of sebum, follicular hyperkeratinisation, C. acnes, and inflammation
- How to identify and grade every acne type — from mild comedonal to severe nodulocystic — using established clinical frameworks

- How to recognise conditions that are commonly confused with acne — including rosacea, perioral dermatitis, fungal acne, and milia — and when to refer
- When and how to refer clients for medical support — recognising the clinical signs that sit outside your scope and referring with confidence

Acne: True or False?
There are countless myths about the causes and treatment of acne. Some of these myths are rooted in folklore, and some have validity, but are not always as simple as they might seem. This chapter discusses and analyzes these many myths, and uncovers which are true and which have no scientific basis, and are not true.
When the myths actually do have validity and a scientific basis can be established, they usually are rooted in the truths that we already know about acne:
Acne is a genetic condition caused by retention hyperkeratosis and excess sebum production.
Acne is not curable, and treatment must be ongoing.
Inflammation has a definite effect on acne and in many cases can cause immediate flares.
Hormones are a major factor in acne, and often hormones are at the root of causing flares.

Acne Analysis
Proper analysis of acne and problem skin conditions is the basis for all aesthetic treatment for clog-prone and acne-prone skin. Determination of acne severity and careful examination of the skin each time allows the esthetician to track the progress of the client, and also to observe conditions that may need medical referral.

Psychology of Acne
Acne is not just a skin condition. For many people it is the thing that shapes how they move through the world. It affects whether they leave the house, whether they will let someone photograph them, whether they feel safe in a room full of people. As an acne specialist, your work is clinical but it is never only clinical. Understanding the psychological dimension of acne is not optional. It is part of the job.
This section gives you the knowledge and practical language to handle the emotional side of acne consultations with skill and confidence. You will not be asked to become a therapist. You will be asked to become the kind of practitioner who knows when the skin is not the only thing that needs attention.

Hormonal Homecare Protocols
What you will cover in this section
Unit HH.1 | The Hormonal Cycle and the Skin
Unit HH.2 | Cycle-Syncing Skincare: A Practical Framework
Unit HH.3 | PCOS-Specific Homecare Protocols
Unit HH.4 | Perimenopause and Menopause Homecare
Unit HH.5 | Building and Communicating a Hormonal Homecare Plan
Hormonal acne is not a straightforward condition to treat because the hormonal environment driving it is not static. It shifts across the menstrual cycle, across conditions like PCOS, and across the decades as women move through perimenopause and menopause. A homecare protocol that ignores this variability is working with one hand tied behind its back.
This section gives you the framework to build homecare plans that account for where a client is in their cycle, what their hormonal picture looks like, and how their skin needs will evolve over time. It is one of the most practical and clinically sophisticated things you can offer a client — and it is something very few practitioners do.

Client Communication & Retention
What you will cover in this section
Unit CC.1 | Setting Expectations from Day One
Unit CC.2 | Managing the 12-Week Acne Programme
Unit CC.3 | Progress Photography Protocols
Unit CC.4 | Handling Client Frustration and Difficult Moments
Unit CC.5 | Retention: Keeping Clients Beyond the Programme
The most technically skilled acne specialist in the room will lose clients if they cannot communicate well. Acne treatment takes time. Progress is not linear. Clients get frustrated. They compare themselves to before-and-after pictures they have seen online. They stop their homecare for two weeks and do not tell you. They come to their sixth appointment expecting to be clear and they are not.
Everything in this section is about managing the human side of a treatment programme with skill and intention. Communication is not a soft skill in acne practice. It is a clinical one.

Business of Acne Specialisation
What you will cover in this section

Unit BAS.2 | Packaging and Pricing Your Acne Programme
Unit BAS.3 | Marketing Yourself as an Acne Specialist
Unit BAS.4 | Building Your Acne Waitlist
Unit BAS.5 | The Numbers: What a Full Acne Practice Looks Like
Completing this certification does not automatically transform your practice. That part is on you. But this section gives you the business framework to do it properly — from how to package your programme and what to charge, to how to position yourself, attract the right clients, and build a practice that is built around acne specialisation rather than one where acne is just another thing you do.
The difference between a practitioner who occasionally treats acne and an acne specialist is not just clinical knowledge. It is how they present themselves, how they structure their services, and what they charge. This section covers all of it.
