About the Course

The Seoul Glass Skin Facial Method is an advanced professional training programme designed for qualified facial practitioners who want to expand their practice through a hydration-focused, barrier-supportive treatment methodology influenced by Korean skincare philosophy. More than simply learning a treatment protocol, this course explores the science behind healthy skin, barrier function and the principles that contribute to long-term skin health. Throughout the programme, practitioners develop a deeper understanding of skin behaviour, consultation and skin analysis, ingredient-led treatment design, clinical decision-making, professional client communication and the complete Seoul Glass Skin Facial Method. By combining evidence-informed theory with practical application, the course develops the professional judgement required to understand not only how each treatment stage is performed, but why it is included and when it may need to be adapted. The treatment incorporates specialist modalities including ultrasonic skin spatula and LED light therapy, alongside controlled exfoliation, strategic product layering, hydration and barrier-supportive skincare. This course is intended as progression training for practitioners who already hold a recognised facial qualification and want to develop their knowledge beyond foundational facial techniques. Upon successful completion of the required theory and practical assessment, students will receive accredited certification in The Seoul Glass Skin Facial Method, with additional training in ultrasonic skin spatula and LED light therapy included within the programme.

What You’ll Need

To perform The Seoul Glass Skin Facial Method professionally, you'll require an appropriate selection of professional skincare products and equipment. This includes: Professional cleansing and treatment products Hydration and barrier-supportive formulations Appropriate exfoliation products An ultrasonic skin spatula An LED light therapy device As this is advanced progression training for qualified facial practitioners, students are expected to already have access to a suitable professional treatment environment and the standard equipment required to perform facial treatments. You do not need to use one specific skincare brand. Products should be selected according to their suitability for professional use, the treatment protocol and the individual client. If you do not yet own a professional skincare range, suitable non-professional products may be used for the practical assessment only, provided they are appropriate for each stage being demonstrated.  Professional skincare products should be used when performing the treatment professionally on clients.

I recently completed the Seoul Formula Korean Glass Skin Facial course, and it was incredible! especially if you’re interested in advanced skincare techniques focused on achieving that radiant, dewy, “glass skin” look. The course was really well structured, learning the fundamentals of Korean skincare philosophy! I would 100% recommend this course to both beginners and professionals who want to expand their knowledge of Korean skincare techniques and it provides a solid foundation for achieving healthy, glowing skin rather than quick fixes 🤍

The whole journey of taking Korean Glass Skin Facial courses was absolutely joyful. The structure of the course was very clear and easy to understand. The learning platform is convenient to use and I can go back to review the text material and protocol video anytime I want. I also got so much help from the course leader Liv, with her helpful information and experience. I would definitely recommend this to anyone who is interested or would like to add on this service to her career path.

I absolutely loved this course. Even though I am already trained in Facials and LED I learned so much. It was so in depth. And what I have learned about the skin and barrier health is going to help me so much with my other treatments.

I have undertaken the glass skin facial course and developed my knowledge so I am confident in which steps to take for customers! I was able to ask as many questions and get a timely response and going above and beyond to clarify anything I wasn’t sure on. This is definitely something I would recommend and I’m looking to undertake more courses soon ! 😍
