Do you struggle with helping your clients manage their acne?

In my practice, I don’t believe in chasing skincare symptoms and giving my patients a homecare and a treatment plan, which will only act as a band-aid and just temporarily address their symptoms. I get to the root cause of the problem so that I can educate my client on how we as a team are going to resolve their skin condition and achieve lasting, meaningful results that will last a lifetime.

Everybody has C. acnes bacteria—which is commonly blamed for causing acne. The skin biome is the ECOSYSTEM of microorganisms that live on the skin, your skin is colonized by millions and millions of bacteria, viruses, and fungi, and just like the microbes in your gut have a more significant impact on overall health, microbes on your skin, which is your largest organ, impact the way it looks and feels and its ability to serve as a barrier between your body and the outside world.

Cutibacterium acnes (formerly Propionibacterium acnes) and its relative Propionibacterium granulosum are essential members of a healthy skin microbiome. These bacteria produce a secretion that has antimicrobial properties and helps maintain an acidic skin pH (5.5). The acidic pH, just like the skin of the scalp, helps defend the skin against pathogens.

A cookie-cutter one size fits all skin regimen is not ideal! Acne is a disease with a broad spectrum of severity and that the skin microbiome is reflective of this significant variation. Acne is the result of a disrupted balance in the microbiota that contributes to disease severity, rather than attributing the condition to one harmful microorganism that has a pretty important role in keeping skin healthy.

Upon completion of MBK Acne Detective Course™ you will be able to:

  • Gain a full and thorough understanding of what retention hyperkeratosis is
  • Learn about various skincare regimes and how skincare and treatments can affect acne
  • Understand the various medications commonly used to treat acne
  • Learn how diet and lifestyle can affect acne and other skin health issues
  • Gain a full and thorough understanding of the many types of acne and what typically causes acne

Once you understand what acne is you'll be taught other factors that will influence the treatment schedule most suitable to your client's acne condition.

This course is currently an intensive brand-neutral acne theory education, with 8 online self-study course modules & handouts for your acne packets, so there are NO quizzes or games to test your knowledge. Any new content added to this course is complimentary to current students. This will effect the price of the course sometime in the near future.

If you LOVE listening to podcasts. Have a listen with Pure Skin OC's podcast called Pure Skin Talk. Deyvn and I talk about the beauty industry, acne tips and my acne course.

This course is not for people who are:

  • If you want to learn about Acne fast and you don't want to take the time to understand and process how it works, how to apply it and how to treat, then this is maybe not the course for you.
  • Don't want to put in the time and effort to learn and master your craft
  • Not willing to do the work to build real authentic relationships
  • Looking for interactive learning with games and quizzes
  • Don't enjoy online learning vs in-class learning

"I have spent a small fortune on classes that were not teaching me anything new, it surely gets frustrating. This course is a go-at-your-own pace and it was perfect! The information is clearly written and a wealth of knowledge. It is not focused on a product line, as most are. If you apply the information to your practice then you will not fail to help any of your acne clients. Acne is not a one size fits all type of disorder, the information provided gives you the pieces of the puzzle you are trying to solve. I promise, if you put the time in to really absorb the course you will help your acne clients. It is far more detailed about the causes of acne and how to clear it than any other course I have taken. If you have been looking for an acne course that you can take from your couch then this is for you. I am extremely grateful to Katie for creating this course! Worth every single cent! "

- Kerri Brooks Pender, Esthetician/Owner, About Face Tampa

"I'm so glad that I took the MBK Acne Detective Course! Earlier this year, I took another acne course and while it was okay, I was still left wondering how to translate and apply what I had learned to the products that I use in clinic.

I love that the MBK Acne Detective Course is not product dependent but also that it gave me WAY MORE information (and in more detail) then the previous course did when it comes to treating acne. Everything is broken down in digestible sizes and it's easy to understand. I feel confident in being able to better assess my clients skin and recommend the appropriate products to help their skin heal and their confidence grow."

- Naomi Mundy, Certified Esthetician/Skin Coach, Naomi Mundy Beauty

"I strongly urge you to take the MBK Acne Detective Ecourse. Katie is one of the most knowledgable estheticians around. Her course will be worth every penny. Not only will you quickly make your money back, but it will give you a sound foundation which will give you the confidence you need to deal with clients."

- Marlene Wolfberg, Licensed Esthetician and Acne Specialist

"I have to say Katie, your course is fabulous. By far the best one I've taken. Since I've taken several I was somewhat hesitant purchasing it because I figured what more could be in it that wasn't in others, but then I reminded myself "THIS IS Katie we are talking about, of course I'm taking this course". And I'm so glad I did. Thank you for reinvigorating my passion for treating acne."

- Veronica Korologos, Licensed Esthetician, Essential Skin Care and Acne Treatment

Is this online acne course for me?
This acne course is aimed at certified/licensed estheticians wanting additional acne knowledge outside of what is traditionally taught in esthetics school. It is brand neutral theory based training and not affiliated with any skincare lines as I do not buy into product lines that believe only their products can "cure/manage" acne. Acne is multi-faceted, for the majority of people, diet and lifestyle are crucial to obtaining and maintaining clear, blemish-free skin. Some people have a genetic component and others have flawless skin.
How is your course different from Face Reality?
Did you know that I too am Face Reality Certified, since 2015? While I LOVED my theory training based on Dr. Fulton's years of acne studies I could not use Face Reality products here in Canada. I did use many of Face Reality's resources and strategies when I did my acne consultations and I could help my clients clear their skin with more confidence. I did not agree with being aggressive in the homecare and treatment plan for the majority of my acne clients. In my practice I operate more on the corneotherapy side of skin health by preserving the integrity of the epidermis. I also focus a lot more on gut health and functional nutrition with my clients. I do have several Face Reality students in this course as they want a different perspective in treating acne to compliment their Face Reality training in their practice.
