The Ultimate Skin Type Guide: “I thought I had dry skin, but why am I still breaking out?” “I used a viral K-Beauty product, but my face turned red and irritated. Why?”
The answer lies in your Skin Type. In the world of high-end Korean dermatology, the simple “Oily vs. Dry” classification is a thing of the past. Today, the gold standard is the Baumann Skin Type System—essentially the “MBTI for your face”—which classifies skin into 16 distinct profiles.
Understanding your unique profile is the “North Star” for your skincare journey. In this guide, we’ll break down the 16 types, suggest the best ingredients for each, and show you how to use YeoTi to find professional treatments tailored to your specific needs at the best local prices.

Decoding the 16 Baumann Skin Type Profiles
The Baumann system uses four parameters to create 16 unique combinations:
- Oily (O) vs. Dry (D): Measured by sebum production and hydration.
- Sensitive (S) vs. Resistant (R): Measures how easily your skin reacts to external stimuli.
- Pigmented (P) vs. Non-Pigmented (N): Propensity to develop freckles, sunspots, or melasma.
- Wrinkled (W) vs. Tight (T): Indicates the rate of aging and skin elasticity.

Common Profiles & Professional Care: A Real Case Study
Let’s look at a typical profile for many travelers visiting Korea: OSNT (Oily, Sensitive, Non-Pigmented, Tight).
| Profile | OSNT (Sensitive Oily) | DSPT (Sensitive Dry) | ORNT (Healthy Oily) |
|---|---|---|---|
| Traits | Acne-prone but reacts to harsh products | Dry patches + pigment concerns | High oil but strong skin barrier |
| Pain Point | Redness and excess shine | Fragile barrier + dark spots | Clogged pores and blackheads |
| Solution | Panthenol & light water-based gel | Bifida ferments & low-pH acids | Salicylic acid & deep cleansing |
🕒 The Transformation Timeline (Case: OSNT Traveler)
- Day 1: Arrived in Seoul with oily, red, and irritated skin due to travel stress.
- Week 1: Used YeoTi to book a “Soothing Hydration Management” (LDM) session.
- Month 1: Skin barrier is restored; oil is balanced, and the “Glass Skin” look is finally achieved!

Smart Pricing
Once you identify your Skin Type, you might consider professional treatments like LDM, Skin Boosters, or medical-grade peels. In Seoul, prices range from $50 to $300, and it’s easy for tourists to get overcharged.
“Afraid of the ‘Tourist Price’ or hidden fees?”
This is why the ‘YeoTi‘ app is essential for your K-Beauty journey:

Crucial Side Effects & Precautions by Type
Choosing the wrong treatment for your Skin Type can do more harm than good:
- Sensitive (S): Avoid high-concentration Retinol or Vitamin C without a patch test.
- Dry (D): Over-exfoliating can strip your barrier and cause premature wrinkles.
- Oily (O): Using heavy oil-based products can clog pores and worsen cystic acne.
