What's my skin type? – Guide and skin type test
Your skin type determines which products work for you. Incorrect skin type diagnosis leads to using the wrong products, and the wrong products worsen the problems you're trying to solve. There are five basic skin types and several proven methods to identify yours. This guide provides you with the tools.
Key takeaways
- 85% of people have combination skin – purely dry or oily skin types are rarer than most believe.
- Skin type (genetic) and skin condition (variable) are different things: you can have a dry skin type but still have dehydrated skin.
- The most reliable test: cleanse without products, wait 30 minutes, and observe without touching your face.
- Your skin type can change with seasons, hormonal cycles, and lifestyle – re-evaluate every 3-6 months.
- Correct skin type identification saves money and provides noticeable improvement within 30 days with a properly tailored routine.
Summary
- There are five skin types: dry, oily, combination, normal, and sensitive.
- Sensitive skin is a characteristic that combines with all four basic types, not a type of its own.
- The naked face method and the blotting test provide the most reliable results at home.
- Skin type changes with age, season, and hormones: re-evaluate every season.
- Dehydrated skin is a condition, not a skin type: all skin types can be dehydrated.
The five skin types: characteristics at a glance
Understanding your skin type means mapping how your skin behaves under normal circumstances. The table below describes the five skin types based on six key characteristics. Use it as a reference when you do your skin type test below.
| Skin Type | Sebum Production | Pores | Moisture Level | Reactivity | Tone Control | Typical Problems |
|---|---|---|---|---|---|---|
| Dry | Low | Barely visible | Low, tight | Medium to high | Matte, sometimes flaky | Dryness, flaking, early fine lines |
| Oily | High | Visible, enlarged | Good (but not hydrated) | Moderate | Shiny during the day | Acne, blackheads, shine |
| Combination | High in T-zone, low on cheeks | Visible in T-zone | Varies by zone | Variable | Oily T-zone, matte cheeks | Acne in T-zone, dryness on cheeks |
| Normal | Balanced | Barely visible | Good | Low | Even and natural | Rarely extreme problems |
| Sensitive | Variable (characteristic, not type) | Variable | Variable | Very high | Redness, reactions | Irritation, redness, stinging |
The Naked Face Method: the most reliable skin type test
The naked face method provides a more reliable picture of your skin type than quick mid-day tests. Cleanse your face with a mild, pH-balanced cleanser. Apply nothing afterwards. Wait exactly 60 minutes at room temperature without touching your face. Then examine your skin in natural light.
What you see and feel after 60 minutes of waiting is your skin in its neutral state. Tight and drawn on the cheeks? Likely dry skin. Uniformly shiny across the entire face? Likely oily skin. Shiny in the T-zone but normal on the cheeks? Combination skin. Neither tight nor oily? Normal skin. Redness or itching without clear cause? Sensitive skin regardless of basic type.
Do not do the test immediately after strong cleansing or exfoliation: it will give a falsely drier result. Do not do it in extreme cold or heat either, as the environment affects sebum production. You will get the most reliable result if you do the test for three consecutive days and note the pattern. Skin type changes with age, climate, and hormonal fluctuations.
Blotting Test: quick diagnosis
The blotting test gives a quick indication of sebum production, not skin type itself. Press a blotting paper against different parts of your face (forehead, nose, cheeks, chin) 2-3 hours after cleansing your skin. Hold the paper up to the light and observe.
- Oil from the entire face: likely oily skin type.
- Oil only in the T-zone (forehead, nose, chin), none from the cheeks: likely combination skin.
- Little or no oil from the entire face: dry or normal skin type.
- Oil combined with tightness: could be dehydrated skin compensating with sebum, not oily skin type.
The blotting test is a good complement to the naked face method. Use both to confirm your diagnosis. The most common mistake is to test too early (immediately after cleansing) or too late (late in the evening when sebum has accumulated).

What exactly is sensitive skin?
Sensitive skin is not a skin type in the same way as dry or oily skin. It is a characteristic: a tendency to react with redness, stinging, itching, or rashes to stimuli that other skin types tolerate. Sensitive dry skin, sensitive oily skin, and sensitive combination skin all exist and require different product strategies.
The most common cause of sensitive skin is a compromised skin barrier. When the barrier does not function optimally, irritants penetrate and cause reactions. This means that "sensitive skin" for many is a temporary condition that improves when the barrier is repaired with ceramides, mild cleansers, and a minimum of active ingredients.
See: sensitive skin and skin barrier.
How does skin type change over time?
Skin type is not static. It is affected by age, hormones, season, and skincare. Oily skin in adolescence can become combination skin in the 30s when estrogen production stabilizes. During pregnancy, combination skin can become extremely oily or dry, depending on the hormonal profile. During menopause, estrogen levels decrease and the skin generally produces less sebum: oily skin can become normal, normal can become dry.
Seasonal changes also affect skin. Cold air and central heating dry out the skin in winter. Warm, humid air increases sebum production in summer. It is normal to adapt your skincare routine seasonally with richer creams in winter and lighter textures in summer. Evaluate your skin type once a season. Skin type changes with age, climate, and hormonal fluctuations.

Routine based on skin type
Once you know your skin type, you choose product textures and ingredients accordingly. Dry skin needs rich ceramide creams; avoid strong exfoliation and alcohol. Oily skin thrives with light gel textures, BHA 2-3 times a week, and niacinamide to regulate sebum production. Combination skin can use zone-based skincare with a light moisturizer in the T-zone and richer cream on the cheeks.
Normal skin has the most freedom: preventive skincare with SPF, a balanced routine, and the introduction of active ingredients based on interest. Sensitive skin should start with a three-step routine (cleansing, moisturizer, SPF) and add one active ingredient at a time. Centella asiatica, niacinamide, and beta-glucan are the safest first active ingredients for sensitive skin.
See: skincare routine by skin type, routine for dry skin and routine for oily skin.
Common mistakes in skin type diagnosis
The most common mistake is to test skin type immediately after cleansing. Skin is always drier right after washing, and the test shows a falsely drier skin type. Testing in the middle of the day gives falsely oilier results. Confusing dehydrated skin with dry skin type leads to using the wrong products: dehydrated skin needs humectants, dry skin needs lipids.
Diagnosing during a period of stress, illness, or the last days of the menstrual cycle gives a temporary picture. Hormones greatly affect sebum production. Not considering the season is another common mistake. Perform the skin type test under normal circumstances, preferably for three consecutive days, to get a representative result. Knowing your skin type determines which products actually work for you.

FAQ: What is my skin type?
Can you have two skin types?
Yes, it's called combination skin. It's the most common skin type. The T-zone (forehead, nose, chin) is oilier while the cheeks are normal or dry. Combination skin sometimes needs zone-based skincare with different products on different parts of the face for best results.
Does skin type change with age?
Yes. Skin generally produces less sebum with age. Oily skin in adolescence often becomes combination skin in the 30s. Estrogen levels affect sebum production, which is clearly seen during menopause. Evaluate your skin type every season and adapt your routine to your current skin type profile.
What is the difference between dry skin and dehydrated skin?
Dry skin is a skin type with a lipid-poor barrier that produces little sebum. Dehydrated skin is a condition of water deficiency that can affect all skin types, including oily skin. Dry skin is treated with ceramides and emollients. Dehydrated skin is treated with humectants like hyaluronic acid and glycerin. See dehydrated skin vs dry skin.
How do you know if you have sensitive skin?
Sensitive skin reacts with redness, stinging, itching, or rashes to products or environmental factors that other skin types tolerate. If your skin reacts to mild toner, fragrance-free products, or temperature changes, your barrier may be damaged. Repair the barrier with ceramides and mild cleansing before assessing if you truly have sensitive skin.
Do diet and lifestyle affect skin type?
Diet and lifestyle affect skin condition but not genetically determined skin type. High glycemic diet and stress temporarily increase sebum production. Lack of sleep impairs barrier function. Ample fluid intake supports skin hydration levels, but does not replace topical moisturizers. Skin type is largely genetically determined.
