The ability to manage skin health through evidence-based practices, progressing from skin type recognition and basic cleansing to ingredient analysis, concern-specific care, dermatological science knowledge, and lasting contributions to skincare culture.
Skincare is the practice of understanding your skin type and condition and maintaining and improving skin health through appropriate products and routines. Progress spans from basic cleansing and moisturizing through sun protection, ingredient literacy, concern-specific targeted care, understanding professional procedures, designing routines for others, creating educational content grounded in dermatological science, and ultimately making lasting contributions that shape skincare culture.
You are entering the world of skincare for the first time. You observe how your skin reacts after cleansing (tightness, oiliness, localized dryness) to roughly identify your skin type. You understand and perform double cleansing using an oil-based cleanser followed by a water-based cleanser, and form the habit of applying moisturizer after washing your face. You recognize the effect of UV exposure on the skin and know that sunscreen exists and is necessary, but consistent daily use is not yet established.
What Comes Next
If you've checked off most of this list, you're ready for the Foundation stage, establishing a basic routine of cleanser, toner, moisturizer, and sunscreen, deepening your understanding of SPF, and recognizing how your skin changes with the seasons. Fitts & Posner(1967)'s Motor Learning theory suggests you're in the cognitive stage where conscious attention to each step (cleansing pressure, moisturizer amount, application sequence) gradually becomes automatic. Try recording your routine steps in a checklist and tracking which ones no longer require deliberate thought.
Serves as the authoritative standard for dermatological care in Korea, providing scientific legitimacy for skin type classification, fundamental care, and UV protection criteria across all level checklists.
Ingredient efficacy, side-effect, and interaction profiles serve as direct evidence for L3 ingredient literacy and L4 concern-specific ingredient combination checklist items.
References the competency standards from the 4-year dermatology residency program to establish expert-level capability boundaries at Levels 6-7.
Analyzes the science of stratum corneum function and skin barrier maintenance, providing evidence basis for L1-L3 cleansing/moisturizing and L4 ingredient-based care checklists.
