Professional Training

YOONSI's techniques and sensibility, built over years in the field

YOONSI does not overlook small differences.
The pressure and angle of the hands, the way we observe skin and scalp
A client's response and the flow of the work
We observe and study every detail
Building techniques and standards of our own.

In Professional Training
We share this practical knowledge and refined sensibility
The signature techniques we have researched and developed ourselves
Without holding back.

For Whom

Who this is for

For those who want to learn the fundamentals properly but do not have a mentor nearby, and who want to acquire the sensibility and practical knowledge of real work that general courses rarely teach.

It also suits working professionals who want to create signature techniques and service standards of their own, study detail more deeply, and raise their expertise beyond familiar techniques.

Recommended for those who want not simply to copy techniques, but to experience up close YOONSI's way of observing, refined sensibility, and standards developed over years in the field, then make them their own.

Before enrollment, we hold an interview to review your experience, goals, and fit for the course. To keep the training focused, we accept one person each month; a two-person reciprocal class counts as one team.

Makeup

Professional Makeup Training

A five-session intensive sharing the signature makeup techniques, detail, and professional standards YOONSI has built through years in the field.

Rather than following a fixed style, students learn to observe skin and faces, bring forward each person's beauty, and develop the judgment to adapt across many faces.

Recommended for

Artists working without a mentor who need fundamentals and field knowledge, professionals seeking signature techniques and standards, and those preparing for a new career or business. It also suits those who want to learn not just technique but how to observe a face and judge what to add or take away.

Application and tuition

Electives use the same tuition basis as Professional Makeup Training. Choose the subjects and number of sessions you need. Both one-to-one and two-person formats are available. For the two-person format, please find the other student and apply together. Schedules are arranged after consultation.

Consultation

Training shaped through consultation

Inquiries are welcome at any time. Training availability depends on the shop schedule and the progress of current students. After reviewing your experience, goals, and preferred field, we will let you know whether the course can proceed and suggest a schedule. An inquiry or consultation does not confirm enrollment. Within the set course duration, we focus more deeply on the areas most relevant to your skill level and goals.

If you are unsure about applying for training, please feel free to contact us at any time.
