To identify your skin type before choosing a dermatology treatment, wash your face with a gentle cleanser, leave it bare for about 30 minutes and check how it looks and feels. Shine all over suggests oily skin, tightness or flaking suggests dry skin, shine only on the forehead, nose and chin suggests combination skin, and stinging or redness after products suggests sensitive skin.
What Are the Main Skin Types?
| Skin type | Common signs |
|---|---|
| Normal | Balanced, not too oily or dry, few reactions to products |
| Oily | Shine across the face, visible pores, more prone to acne |
| Dry | Feels tight, may look rough or flaky |
| Combination | Oily in the T-zone (forehead, nose, chin), normal or dry on the cheeks |
| Sensitive | Stinging, burning, itching or redness after some products |
Signs of Each Skin Type Through the Day
- Oily: shine across the face by midday, makeup slides off easily.
- Dry: feels tight after washing and through the day, may flake around the nose and cheeks.
- Combination: shiny forehead and nose by afternoon, while the cheeks stay comfortable or dry.
- Normal: comfortable most of the day with little shine or tightness.
- Sensitive: stings or reddens with some products, weather or heat.
Skin Type vs Skin Condition
Skin type and skin condition are different, and both affect treatment.
- Skin type describes your skin's usual oil and moisture level, such as oily, dry or combination. It is fairly stable but can change with age, hormones and climate.
- Skin condition is a specific issue, such as acne, melasma, rosacea or dehydration. It can occur with any skin type and often changes with treatment.
For example, oily skin can also be dehydrated, and dry skin can also have acne. The doctor considers both when choosing a treatment.
Skin type
- Your usual oil and moisture level
- Oily, dry, combination, normal or sensitive
- Fairly stable, but changes with age and climate
Skin condition
- A specific issue on the skin
- Acne, melasma, rosacea or dehydration
- Can occur with any skin type
How Can You Test Your Skin Type at Home?
- Wash your face with a gentle cleanser.
- Pat it dry and do not apply any products.
- Wait about 30 minutes.
- Check your skin in a mirror and note where it looks shiny and where it feels tight.
This test gives a starting point. A dermatologist can confirm your skin type and check for conditions such as acne, rosacea or eczema that also affect treatment choice.
Skin Type Mistakes to Avoid
- Judging skin type right after washing with a harsh cleanser
- Assuming oily skin does not need moisturizer
- Using strong products for acne on sensitive skin
- Changing your whole routine just before a treatment trip
What Is the Fitzpatrick Skin Type?
Dermatologists also classify skin by how it reacts to the sun, using the Fitzpatrick scale from type I to VI.
| Type | Typical reaction to the sun |
|---|---|
| I–II | Burns easily, tans little or not at all |
| III–IV | Burns sometimes or rarely, tans gradually or easily |
| V–VI | Rarely or never burns, tans darkly |
Darker skin types have a higher risk of pigmentation after inflammation, so the doctor adjusts laser type and settings.
Why Does Skin Type Matter for Dermatology Treatment?
Your skin type helps the doctor choose treatments, settings and aftercare. Oily skin with enlarged pores may suit treatments aimed at pores and skin texture. Oily or combination skin that breaks out may need acne treatments. Dry or sensitive skin often needs extra care with hydration and products that are less likely to irritate.
How Skin Type Affects Common Treatments
| Skin type | Points the doctor may consider |
|---|---|
| Oily | Pore and acne treatments; may tolerate some peels well |
| Dry | Extra hydration before and after lasers; gentle aftercare |
| Combination | Different care for the T-zone and cheeks |
| Sensitive | Calming the skin first; gentler devices or settings |
Skin Type and Sensitivity
Sensitivity can occur with any skin type. Dry skin with a weakened barrier often becomes sensitive, and oily skin can become irritated by strong acne products. If your skin stings or reddens easily, tell the doctor even if you are not sure of your skin type.

How Does Skin Type Change Over Time?
How Skin Type Changes With Seasons and Travel
Your skin can behave differently depending on climate and routine.
- Korean summer: heat and humidity can make skin oilier and increase breakouts.
- Korean winter: cold, dry air and indoor heating can make skin drier and more sensitive.
- Long flights: dry cabin air can leave skin dehydrated and tight.
- New products: trying many new products on a trip can cause irritation.
If your skin feels different in Seoul from at home, tell the doctor. They will assess your skin as it is on the day of the consultation.
Skin Type, Climate and Your Trip
If you travel from a humid climate to a dry season in Seoul, or the other way around, your skin may feel different for a few days. Bring products for both conditions, such as a lighter moisturizer and a richer cream, and adjust them to how your skin feels. Mention any recent change in your skin to the doctor.
Skin Type and Aging
Skin often becomes drier with age, as oil production decreases. Someone with oily skin in their twenties may have normal or combination skin later. This is one reason to recheck your skin type over time and adjust your skincare and treatments accordingly.
How Should You Care for Your Skin Type?
- Oily: a gentle foaming cleanser and a light, non-comedogenic moisturizer.
- Dry: a non-foaming cleanser and a richer cream with ceramides.
- Combination: lighter products on the T-zone and more moisture on the cheeks.
- Sensitive: fragrance-free products, introduced one at a time.
- All types: broad-spectrum sunscreen every day.
Preparing Your Skin Before Treatment
- Keep your routine simple in the week before treatment.
- Avoid new products, scrubs and strong acids.
- Moisturize well if your skin is dry or dehydrated.
- Protect your skin from the sun and avoid tanning.
- Ask the doctor whether to pause retinoids before treatment.
What Should You Tell or Ask the Dermatologist?
- Your skin type from the at-home test
- Products that have caused stinging, redness or breakouts
- Your current skincare routine, including retinoids or exfoliating acids
- Medications and any skin conditions you have been diagnosed with
How the Dermatologist Confirms Your Skin Type
The at-home test gives a useful starting point, but the dermatologist confirms your skin type during the examination. The doctor looks at oil, dryness, pores and sensitivity, asks how your skin reacts to the sun and checks for conditions such as acne or rosacea.
