Have you ever faced the frustration of using a moisturizer that feels overly heavy, leaving your skin shinier and greasier than usual? Conversely, have you tried a product that resulted in a tight and itchy sensation? These experiences often stem from the fact that such products do not align with your specific skin type!
Identifying your skin type is crucial for making informed choices regarding cosmetic products and developing personalized skincare routines tailored to your unique needs. This understanding can ultimately save you both time and money by helping you avoid products that are ill-suited for your skin.
So, how can you determine your skin type? This article will delve into the five distinct skin types, the factors that define them, and provide you with three simple tests you can perform at home to discover yours.
The Skin's Natural Moisturizing Mechanism
To grasp how skin is categorized into various types, it's essential to first understand how it maintains its natural moisture.
The skin acts as a protective barrier, separating our internal environment from external influences, thus regulating what enters and exits the body (such as water) and shielding us from external harm [1]. One of the key functions of the skin is to produce sebum (or oil), which serves not only antimicrobial purposes but is also vital for keeping the skin lubricated and supple. This helps to lock in moisture and inhibit dryness [2].
Produced by sebaceous glands, which are densely concentrated on our face and scalp [2], sebum consists of a unique blend of lipids, including triglycerides and fatty acids, wax esters, squalene, and trace amounts of cholesterol [3]. The more active these sebaceous glands are, the higher the lipid production and the better the skin’s lubrication.
What Exactly is a “Skin Type”?
When we refer to “skin type,” we are essentially discussing the level of oil production by the skin, which typically correlates with its ability to retain moisture.
Based on the degree of oil production, skin can be categorized into four primary types: oily, dry, combination, and normal. Additionally, there exists a fifth type, sensitive skin, which can manifest alongside any of the other four types in certain individuals.
Let’s take a closer look at each type.
1. Oily Skin
Individuals with oily skin generally produce excess sebum, resulting in a shiny, greasy appearance [4]. Enlarged pores are common due to the increased size and activity of sebaceous glands, giving the skin a thicker texture to the touch. This skin type may also be associated with comedones, such as blackheads and whiteheads, along with acne scars and irritations [5].
2. Dry Skin
People with dry skin do not generate sufficient sebum to retain moisture, leading to visibly dehydrated, ashy, or flaky skin. This type often feels tight and itchy, with potential cracking in severe cases. Pores are less visible due to reduced activity of sebaceous glands. When touched, dry skin feels cold, thin, and rough, exhibiting minimal elasticity and often featuring dehydration lines [5].
3. Combination Skin
Combination skin is typically marked by an oily T-zone (forehead, nose, and chin) that appears shiny, contrasted with dry or normal skin on the rest of the face [5]. If you observe that certain areas of your skin are oilier while others feel dry, this indicates you have combination skin.
4. Normal Skin
Normal skin appears balanced, showcasing a smooth and even texture without excessive shine or visible pores [5]. Individuals with normal skin perceive their complexion as neither excessively oily nor dry, allowing them to use a wide variety of skincare products without issue. This skin type feels fresh and smooth to the touch, with a healthy thickness and optimal hydration, elasticity, and firmness [5].
5. Sensitive Skin
Sensitive skin is highly reactive to various elements, including skincare products and cosmetics [6]. It can easily become inflamed, displaying visible redness and sensations of burning, stinging, or pain. While often associated with dry skin (showing signs of tightness and flaking), other skin types can also exhibit sensitivity.
Conditions like acne, rosacea, or various dermatoses have been linked to heightened skin reactivity, further characterizing sensitive skin [6].
How to Determine Your Skin Type
Recognizing your skin type can sometimes be challenging. While some individuals find it straightforward to identify whether their skin is oily or dry, for others, the answer may not be as clear.
If you’re seeking clarity about your skin type, here are three easy tests you can perform at home.
TEST #1: WASH, WAIT, AND OBSERVE
This first test relies on keen observation of your skin after cleansing. Follow these straightforward steps:
1. Thoroughly cleanse your face using a gentle cleanser to avoid stripping your skin of its natural oils.
2. Gently pat your skin dry with a washcloth and take note of how it feels immediately afterwards (refer to the notes in the table below).
3. Refrain from applying any products for two hours—just let your skin breathe.
4. After two hours, check your skin in the mirror and assess its condition. The table below summarizes key observations for each skin type:

After 2 hours

Sensitive
TEST #2: BLOTTING PAPERS
If simple observation is insufficient, you can use blotting papers designed to absorb oil upon contact, allowing you to assess the quantity of oil your skin produces.
After completing Test #1, gently press blotting papers onto your forehead, nose, chin, and cheeks, ensuring you apply a bit of pressure to enhance adhesion.
Observe where the blotting papers collect oil (indicating oil presence) and where they do not stick (indicating minimal or no oil). The table below illustrates the expected results for each skin type:
