Skin Type Guide: How to Determine Your Skin Type
How do you determine your skin type? Characteristics of dry, oily, combination, normal, and sensitive skin, tests, and skincare recommendations for each type.
Skin Type Guide: The First Step to Proper Care
The foundation of building an effective skincare routine starts with correctly identifying your skin type. Products chosen for the wrong skin type can increase skin problems instead of providing expected benefits. Applying heavy creams to oily skin can lead to acne, while using harsh cleansers on dry skin can cause irritation and aging.
In this comprehensive guide, we'll detail how to determine skin types, characteristics of each skin type, and proper care strategies. After determining your skin type, you can learn about active ingredients in our Vitamin C Serum Guide and Retinol Usage Guide articles.

What is Skin Type and Why Does It Matter?
Skin type is your skin's natural characteristic determined by genetic makeup, sebum (oil) production, and moisture balance. Your skin type is largely dependent on genetic factors, but age, hormonal changes, climate, and lifestyle can also influence it.
Skin Type vs Skin Condition
Skin type is genetic and permanent (e.g., oily skin). Skin condition is temporary and changeable (e.g., dehydration, sensitivity, acne). You might have dry skin type but not be dehydrated at the moment. Or you might have oily skin while experiencing temporary sensitivity.
Benefits of Knowing Your Skin Type
- Correct product selection: You choose formulas suitable for your skin
- Effective results: Products work better
- Money savings: You don't waste money on wrong products
- Problem prevention: Issues from improper care are prevented
- Customized routine: You can create a care routine tailored to you
5 Basic Skin Types
Dermatology generally defines 5 basic skin types:
Skin Types Summary
Insufficient sebum production, moisture loss, tightness sensation.
Requires rich moisturizers, occlusive barriers, gentle cleansers.
Excessive sebum production, shiny appearance, enlarged pores.
Requires lightweight moisturizers, BHA exfoliants, mattifying products.
T-zone oily, cheeks normal or dry.
Requires zone-specific care, balancing formulas.
Balanced sebum production, neither too oily nor too dry.
Tolerates most products, maintenance care is sufficient.
Skin that easily becomes irritated, reddens, shows reactions.
Requires fragrance-free, minimal ingredient, soothing formulas.
Skin Type Determination Tests
You can use the following methods to determine your skin type.
Test 1: Post-Wash Observation Test
This test is the simplest way to understand your skin's natural state.
How to Do It:
- Wash your face with a gentle cleanser
- Pat dry and do not apply any product
- Wait 30-60 minutes
- Observe your skin
Evaluate the Results:
| Observation | Skin Type |
|---|---|
| Tightness and dryness on entire face | Dry |
| Noticeable shine on entire face | Oily |
| Shine in T-zone, normal/dryness on cheeks | Combination |
| Comfortable, neither tightness nor shine | Normal |
| Redness, stinging or itching | Sensitive |
Tip
You can also do this test when you wake up in the morning, before washing your face. Seeing how your skin behaves overnight can be a good indicator.
Test 2: Blotting Paper Test
A practical test to measure sebum production.
How to Do It:
- After waking up in the morning (before washing) or 2-3 hours after cleansing
- Press a clean blotting paper to your face
- Test T-zone (forehead, nose) and cheeks separately
- Hold the paper up to light
Evaluate the Results:
| What's Visible on Paper | Skin Type |
|---|---|
| No oil residue, paper is dry | Dry |
| Visible oil marks everywhere | Oily |
| Oil marks only in T-zone | Combination |
| Very light, balanced oil trace | Normal |
Test 3: Pore Analysis
Pore size and visibility gives hints about skin type.
How to Do It:
- Stand in front of a well-lit mirror
- Examine your face closely
- Note the size and distribution of pores
Evaluate the Results:
| Pore Condition | Skin Type |
|---|---|
| Very small, almost invisible | Dry |
| Large, visible, on entire face | Oily |
| Large in T-zone, small on cheeks | Combination |
| Medium size, even distribution | Normal |
Expert Opinion
— Dermatologist OpinionPore size is genetic and cannot be permanently "shrunk." However, clean and unclogged pores appear smaller. Regular exfoliation and cleansing improves pore appearance.
Test 4: End of Day Evaluation
How to Do It:
- Do your morning skincare routine
- Don't wear makeup or apply additional products throughout the day
- Evaluate your skin in the evening
Questions:
- Is your skin shiny or matte?
- Did makeup (if worn) slide, crack, or stay put?
- Do you feel tightness or dryness?
- Is there redness or irritation?
Dry Skin
Characteristics
Dry skin is characterized by insufficient sebum production and compromised skin barrier.
Signs:
- Constant tightness and dryness feeling
- Flaking, scaling
- Matte, dull appearance
- Invisible or very small pores
- Tendency toward early wrinkles
- Dryness that worsens in cold weather
- Makeup cracking or caking
Warning
Dry skin and dehydrated skin are different. Dehydration is temporary and can occur in any skin type. Dry skin is a permanent skin type. Dehydrated skin results from lack of water, while dry skin results from lack of oil.
Causes of Dry Skin
- Genetics: The most important factor
- Age: Sebum production decreases with age
- Environmental: Cold, dry air, low humidity
- Wrong products: Harsh cleansers, alcohol-based toners
- Hot water: Extended hot showers strip skin oils
- Medical conditions: Eczema, psoriasis, thyroid disorders

Oily Skin
Characteristics
Oily skin is characterized by excessive sebum production.
Signs:
- Constant shiny appearance (especially T-zone)
- Large, visible pores
- Prone to acne and breakouts
- Blackheads and whiteheads
- Thick skin texture
- Makeup sliding or melting
- Increasing oiliness throughout the day
Advantage of Oily Skin
Oily skin ages more slowly! Natural sebum keeps skin moisturized and elastic, delaying wrinkle formation. People with oily skin in their 40s generally look younger.
Causes of Oily Skin
- Genetics: Main factor
- Hormones: Androgens increase sebum production
- Age: More prominent in youth, decreases with age
- Climate: Increases in hot and humid weather
- Diet: High glycemic index foods
- Stress: Cortisol increases sebum production
- Wrong products: Heavy creams, comedogenic products
Care Strategy for Oily Skin
Key Ingredients for Oily Skin
Oil-soluble, penetrates pores.
Cleans pores, controls sebum, prevents acne.
Vitamin B3 derivative.
Regulates sebum production, makes pores appear smaller.
Oil-absorbing natural mineral.
Absorbs excess oil, cleans pores.
Antibacterial and sebum-regulating.
Controls acne, reduces oiliness.
Provides oil-free hydration.
Oily skin needs moisture too! Provides lightweight hydration.
Things to Avoid:
- Heavy, oil-based creams
- Comedogenic (pore-clogging) oils
- Overly harsh cleansers (makes skin more oily!)
- Alcohol-based products (temporarily mattifies, increases oil long-term)
For special serum recommendations for oily skin, check our Serum Recommendations for Oily Skin guide. Also, Salicylic Acid (BHA) is very effective for oily skin.
Warning
Trying to "dry out" oily skin is the biggest mistake. Skin produces more sebum to compensate for lost oil. Balanced hydration is essential.

Universal Steps
The basic routine is the same for every skin type; what changes are the ingredients and formulas:
Morning:
- Cleansing (or just water)
- Serum/Active (optional)

For Beginners
If you're just starting, avoid complex routines. Cleanser + Moisturizer + SPF is sufficient. You can add actives after establishing basic steps.
Frequently Asked Questions
Can I have multiple skin types?
Yes, this is called "combination skin." Different areas of your face can have different characteristics. The most common combination is oily T-zone and dry/normal cheeks.
My skin type has changed over the years, is that normal?
Completely normal. Age, hormones, season, diet, and lifestyle can affect your skin type. Especially in women, increased dryness after menopause is very common.
Is sensitive skin a separate type or a condition?
It can be both. Some people are genetically sensitive skin, while in others sensitivity is a temporary condition (e.g., skin barrier damage, allergy). For persistent and severe sensitivity, consult a dermatologist.
Does pore size determine skin type?
Pore size gives hints about skin type but isn't the sole determinant. Pores are generally more visible in oily skin, almost invisible in dry skin.
I have oily skin but also feel dry. How is this possible?
This is called "dehydrated oily skin." Your skin is oily but lacks moisture. This usually results from harsh cleansers or insufficient hydration. Use oil-free but hydrating products.
Can I change my skin type?
You can't completely change your skin type because it's largely genetic. However, with proper care you can minimize and balance the negative aspects of your skin type.
Conclusion
Correctly determining your skin type is the foundation of an effective skincare routine. You can easily identify your skin type with post-wash observation, blotting paper test, and pore analysis.
Important Reminders:
- Skin type is genetic but can change
- Skin type is not equal to skin condition (temporary issues)
- Correct diagnosis = Correct product selection
- Evaluate 1-2 times a year
- Consult a dermatologist when in doubt
