Before you buy a single product, it helps to know what you're working with. Learning how to determine your skin type is the first, most useful step in building a routine that actually fits your face—because the same cleanser that leaves oily skin fresh can leave dry skin tight and flaky. The good news: you can figure out "what is my skin type" at home in about a day, with nothing but a mirror, a gentle cleanser, and a little patience.
Skin type vs. skin concern (they're not the same thing)
People often mix these up, so let's clear it up first.
- Skin type is your baseline—largely genetic, fairly stable, and mostly about how much oil your skin naturally produces. Think oily, dry, combination, normal, or sensitive.
- Skin concerns are the specific things you'd like to improve: acne, dark spots, redness, fine lines, dullness, enlarged pores, and so on. These come and go and often stack on top of your type.
Someone can have oily skin and dark spots, or dry skin and redness. Your type sets the foundation; your concerns get layered on top. Knowing both is what makes a routine feel tailored instead of generic.
The 5 skin types, explained
Oily
Your skin looks shiny across the face, especially the T-zone (forehead, nose, chin), and often before midday. Pores tend to look larger, and you may be more prone to congestion and breakouts. The upside: oily skin often shows fine lines a little later.
Dry
Skin feels tight, especially after cleansing. You might notice flaking, rough patches, a dull look, or a general lack of "bounce." Dry skin makes less oil than it needs, so it can struggle to hold onto water.
Combination
The most common setup: an oily T-zone with normal-to-dry cheeks. Your forehead and nose get shiny while your cheeks feel comfortable or slightly tight. This is the heart of the oily vs dry skin debate—combination skin is simply both, in different zones.
Normal
Balanced. Not noticeably oily or dry, pores aren't especially prominent, and your skin generally feels comfortable. Lucky you—though "normal" skin still benefits from sun protection and consistency.
Sensitive
Sensitive skin reacts easily—stinging, burning, redness, or itching in response to products, fragrance, weather, or friction. Sensitivity can ride along with any of the other types (you can have oily-sensitive or dry-sensitive skin), and it's usually a sign your barrier needs gentler care.
How to determine your skin type at home
Here are three simple methods. The bare-face test is the most reliable, so start there.
Method 1: The bare-face test (most accurate)
- Cleanse with a gentle, non-stripping cleanser and pat dry.
- Wait 30 minutes. Don't apply anything—no moisturizer, serum, or SPF. Let your skin return to its natural state.
- Observe in good lighting. Notice how your skin feels and looks across the forehead, nose, chin, and cheeks.
Read your results:
- Shiny all over → likely oily
- Tight, flaky, or rough everywhere → likely dry
- Shiny T-zone, comfortable or tight cheeks → likely combination
- Comfortable and balanced → likely normal
- Any stinging, burning, or blotchy redness during the wait → a sign of sensitivity
Method 2: The blotting sheet test
Press a clean blotting sheet (or a single-ply tissue) against different areas of your face midday, then hold it to the light.
- Lots of oil from all zones → oily
- Little to no oil, skin feels tight → dry
- Oil from the T-zone only → combination
Method 3: The day-in-the-life check
Sometimes the best data is just paying attention. Over a normal day, ask yourself:
- Does your face get shiny by lunch, or only your nose and forehead?
- Does skin feel tight after washing, or comfortable?
- Do certain products, fragrances, or cold weather make you red or itchy?
One caveat: your "type" can shift with seasons, hormones, climate, and age. Skin often runs drier in winter and oilier in humidity, and it tends to get drier over the decades. Retest a couple of times a year rather than assuming your teenage skin type is your forever type.
Why your skin barrier is the real story
Underneath all five types is one shared structure: the skin barrier, often described as a "brick wall" where skin cells are the bricks and natural oils and lipids are the mortar. When that mortar is intact, moisture stays in and irritants stay out. When it's compromised—by over-washing, harsh actives, or cold, dry air—almost any skin type can start acting dry, red, and reactive.
This is why the same person can test as "dry" one month and "sensitive" the next: a stressed barrier mimics both. If your skin feels tight, stingy, or blotchy no matter what you do, focus on gentle, barrier-supporting care first. Our dry skin and barrier repair guide walks through exactly how, and if easy redness is your main clue, how to calm redness and soothe sensitive skin is a good next read.
Turning your type into a routine
Once you know your type, the building blocks are similar for everyone—cleanser, treatment (as needed), moisturizer, and daily SPF—but the textures and strengths change.
- Oily / combination: lightweight gel or lotion textures, a gel cleanser, non-comedogenic formulas. You still need moisturizer—skipping it can actually push skin to make more oil.
- Dry: creamier cleansers and richer moisturizers, ingredients that draw in and seal moisture.
- Sensitive: fragrance-free, short ingredient lists, and one new product at a time so you can spot reactions.
- Everyone: daily sunscreen, which supports every type and helps prevent the look of dark spots and early lines.

Let a skin type quiz do the sorting
At-home tests are great, but they only tell you your type—not how it interacts with your specific concerns. That's where a structured skin type quiz helps.
GlowGuide's free questionnaire pinpoints your skin type and then maps it against all 12 common concerns—acne, congestion, oiliness, dryness, redness, dark spots, fine lines, firmness, dullness, pores, under-eye circles, and sun damage—to seed a personalized report. You can also add an optional, on-device selfie step that reads general cues like tone evenness and radiance right in your browser; here's how AI skin analysis works and how to take a good selfie for it.
The result is a routine, product suggestions, and—if you want to go further—in-clinic options matched to what your skin is actually telling you. Ready to skip the guesswork? Take the free skin quiz and get your type in a couple of minutes.
The bottom line
Figuring out your skin type at home is genuinely simple: cleanse, wait 30 minutes, and read how your skin behaves. Match your type to the right textures, protect your barrier, wear sunscreen daily, and re-check with the seasons. From there, your concerns tell you what to fine-tune. When you're ready for a personalized starting point, GlowGuide can map your type and concerns into one clear plan.
