Introduction
Finding the perfect skincare routine begins with a moment of self-discovery. We often search for a "miracle" product, but the true secret to a radiant complexion lies in understanding the unique biology of your own face. In the world of professional skincare, we recognize that your fundamental skin type is determined by how oily or dry the skin is. This balance, or lack thereof, dictates how your skin reacts to the environment, how it ages, and which botanical actives will best support its health. At Yon-Ka Paris, we have spent over 70 years perfecting the art of phyto-aromatic care to harmonize these different skin needs. In this article, we will explore how to accurately identify your skin type, the biological factors behind oil production, and how to build a personalized ritual that brings your skin into beautiful alignment.
Quick Answer: Your skin type is primarily classified by the amount of sebum (natural oil) your sebaceous glands produce. This genetic blueprint determines whether your skin is categorized as oily, dry, normal, or combination, and dictates the specific lipid and hydration support your barrier requires.
The Biology of Sebum and Skin Type
To understand why skin type is determined by how oily or dry the skin is, we must look at the sebaceous glands. These microscopic glands are located just beneath the surface of the skin, usually attached to hair follicles. Their primary job is to produce sebum, a complex mixture of lipids (fats) that creates a protective coating on the skin’s surface.
Sebum is essential for skin health. It acts as a natural lubricant, preventing excessive water loss and protecting the skin from environmental stressors like wind and pollutants. When these glands are in perfect harmony, the skin appears "normal"—supple, clear, and balanced. However, genetics, hormones, and age often dictate a different rhythm for these glands.
When the sebaceous glands are overactive, the resulting excess oil leads to what we classify as an oily skin type. Conversely, when these glands produce insufficient lipids, the skin lacks its protective "shield," leading to a dry skin type. Because this oil production is a biological constant for most of our adult lives, your skin type remains relatively stable, though it can be influenced by external factors.
The Five Primary Skin Types
While every individual's skin is unique, the professional skincare world generally recognizes five major categories. Understanding where you fall on this spectrum is the first step toward choosing the right botanical support.
Normal Skin
Normal skin is the biological "gold-standard" of balance. In this skin type, sebum production is well-regulated—neither too much nor too little. The texture is usually smooth, pores are fine and barely visible, and the skin is not prone to frequent breakouts or significant sensitivity. If you have normal skin, your goal is "maintenance and protection," ensuring that environmental stressors do not disrupt this natural equilibrium.
Oily Skin
Oily skin is characterized by a high rate of sebum production. You may notice a persistent shine, especially by midday, and a heavier or "greasy" feel to the touch. Because excess oil can trap dead skin cells within the pores, this skin type is often associated with enlarged pores and a higher frequency of blemishes or blackheads.
Dry Skin
It is a common misconception that dry skin is simply skin that needs water. In reality, dry skin lacks oil. Because the skin isn't producing enough natural lipids, the moisture barrier is often compromised. This allows water to escape too easily—a process known as transepidermal water loss (TEWL). Dry skin often feels tight, looks dull, and may exhibit flaking or premature fine lines.
Combination Skin
Perhaps the most common type, combination skin experiences a "split personality." Usually, the T-zone (the forehead, nose, and chin) is oily or prone to larger pores, while the cheeks and jawline remain normal or even dry. Managing combination skin requires a "zonal" approach to skincare, treating different areas of the face with targeted formulas.
Sensitive Skin
Unlike the other types, sensitive skin is defined more by its reactivity than its oil levels. However, it is frequently linked to dry skin because a lack of protective oils makes the skin more vulnerable to irritants. Sensitive skin may appear red, feel itchy, or experience a stinging sensation when exposed to certain ingredients or environmental changes.
Key Takeaway: Your skin type is a genetic baseline. While you cannot "change" your genetics, you can manage the manifestations of your skin type through consistent, targeted phyto-aromatic rituals.
Distinguishing Between Dry and Dehydrated Skin
One of the most important lessons in skincare education is the difference between dry and dehydrated skin. Because skin type is determined by how oily or dry the skin is, "dry" refers specifically to a lack of oil. Dehydration, however, is a skin condition that refers to a lack of water.
Myth: "My skin is oily, so I don't need a moisturizer." Fact: Oily skin can still be dehydrated. If you strip away too much oil with harsh cleansers, your skin may actually produce more oil to compensate for the lack of water, leading to a complex cycle of oiliness and dehydration.
Dehydrated skin can affect any skin type—even the oiliest. It often looks "crêpey" or dull and may feel tight despite having a layer of oil on the surface. To address this, we use humectants like hyaluronic acid (a molecule that can hold 1,000 times its weight in water) to pull moisture into the skin without adding heavy oils.
How to Determine Your Skin Type at Home
You don't need a laboratory to understand your skin's needs. There are two reliable methods to assess your skin type in the comfort of your own home. For both methods, start by gently cleansing your face and then waiting for 30 minutes without applying any products.
The "Watch and Wait" Method
After 30 minutes of "bare" skin, observe your face in a well-lit mirror.
- Oily: If your face shows shine on the cheeks, forehead, and nose, you likely have oily skin.
- Dry: If your skin feels tight, looks parched, or shows visible flakes, you have dry skin.
- Combination: If your nose and forehead are shiny but your cheeks feel tight or look matte, you have combination skin.
- Normal: If your skin feels comfortable—neither tight nor greasy—you have normal skin.
The Blotting Sheet Method
Take a clean blotting paper and gently press it against different areas of your face.
- Oily: The paper picks up oil from all areas of the face.
- Dry: The paper picks up little to no oil.
- Combination: The paper picks up oil from the T-zone but remains clean when pressed to the cheeks.
- Normal: The paper shows only a minimal, even amount of oil from across the face.
The Phyto-Aromatic Approach to Skin Types
At the heart of every Yon-Ka ritual is our Quintessence. This exclusive complex of five essential oils—lavender, geranium, rosemary, cypress, and thyme—is 100% natural and active. We use this foundation to balance the skin, regardless of whether it is oily or dry.
Our philosophy is built on the Yon-Ka Ritual:
- Cleanse: Respecting the skin's pH and barrier.
- Mist: Preparing the skin with our signature Lotion Yon-Ka PNG.
- Treat: Delivering concentrated botanical actives through serums.
- Moisturize: Providing the specific lipids or water-binding ingredients the skin type requires.
Managing Oily Skin with Precision
If your skin type is determined to be oily, your goal is to regulate sebum and refine texture without causing irritation. Many people make the mistake of using aggressive, alcohol-heavy products that "strip" the skin. This often backfires, as the skin enters a state of "reactive seborrhea," producing even more oil to protect itself.
Step 1: Gentle Purification Start with a cleanser like Gel Nettoyant. This azure-blue foaming gel uses mild surfactants to remove excess oil and impurities while respecting the skin’s delicate acid mantle (the protective film on the skin's surface).
Step 2: Phyto-Aromatic Toning Mist with Lotion Yon-Ka PNG (the version specifically designed for normal to oily skin). This mist contains the Quintessence and helps to purify and tighten the appearance of pores.
Step 3: Balancing and Mattifying Finish with a lightweight moisturizer. Nude Perfect Fluide is an excellent choice for oily skin; it acts as a "blurring" treatment that minimizes the look of pores and controls shine throughout the day using a 96% natural-origin formula.
Nourishing Dry Skin Types
Because dry skin lacks the necessary lipids to hold onto moisture, the ritual must focus on "lipid-replenishing" and "barrier-repair." We look for rich, botanical butters and oils that mimic the skin's natural sebum.
Step 1: Creamy Cleansing Dry skin thrives with a milk cleanser like Lait Nettoyant. This silk-textured milk removes makeup and debris while leaving a light, protective veil of moisture on the skin.
Step 2: Hydrating Mist Use Lotion Yon-Ka PS (the version for dry and sensitive skin). This alcohol-free mist provides an immediate soothing sensation and prepares the skin to absorb the richer creams to follow.
Step 3: Deep Lipid Support For dry skin, a serum like Serum Omega is essential. It is rich in essential fatty acids (Omega 3, 6, and 9) derived from botanical oils like sacha inchi and pomegranate. Follow this with Hydra n°1 Crème, a long-lasting hydrating cream that uses two weights of hyaluronic acid to treat both surface dryness and deeper dehydration.
Balancing Combination and Normal Skin
For combination skin, the challenge is to hydrate the dry areas without over-burdening the oily ones. For normal skin, the goal is to protect against the first signs of aging and environmental damage.
The Hybrid Approach Many with combination skin find success using a lightweight fluid like our face moisturizers during the day to protect against pollution and oxidative stress (damage caused by unstable molecules), and a more targeted treatment at night.
If you are noticing the first signs of fine lines, Élastine Nuit can support the skin's natural repair process during sleep. For those with a perfectly balanced normal skin type, our face care collection provides the daily maintenance needed to keep the skin looking vibrant and healthy.
Targeted Treatments for All Types
Regardless of whether your skin type is determined by how oily or dry the skin is, specific concerns like the eye area or dullness require extra attention.
- For the Eyes: The skin around the eyes is thinner and has fewer sebaceous glands than the rest of the face. Phyto-Contour is a rosemary-infused cream designed to address the appearance of puffiness and dark circles, providing a "lifted" look to the gaze.
- For Brightening: If your skin looks dull or "tired," Serum C20 provides a stable, 20% concentration of Vitamin C alongside sweet orange essential oil to visibly brighten the complexion and support natural collagen.
- For Exfoliation: All skin types benefit from removing dead cells, but dry and sensitive types should avoid harsh scrubs. Gommage Yon-Ka is a botanical, grain-free peel that uses carob and lime essential oil to gently "polish" the skin without abrasion.
The Role of Professional Expertise
While an at-home routine is the foundation of skin health, professional intervention can take your results to the next level. Because your skin type is determined by biological factors, a professional aesthetician can perform a much deeper analysis than a mirror can.
In a professional spa setting, we use tools and techniques to measure hydration levels and look at the skin under magnification. A professional treatment, such as those found through our spa treatments, allows for deep-cleansing extractions for oily skin or intensive, professional-grade hydration masks for dry skin. These treatments often use concentrated versions of our formulas that are only available in a clinical or spa environment.
Note: When introducing new botanical products, especially those containing active essential oils, we recommend a patch test. Apply a small amount of product to your inner forearm and wait 24 hours to ensure your skin welcomes the new ingredients.
External Factors That Influence Skin Behavior
While your "base" skin type is determined by how oily or dry the skin is via genetics, the world around you can cause temporary shifts in how your skin behaves.
- Climate: Humidity can cause sebaceous glands to be more active, making skin feel oilier in the summer. Cold, dry winters can strip lipids away, making even oily skin feel temporarily dry or sensitive.
- Hormones: Fluctuations in hormones (during puberty, pregnancy, or menopause) directly affect sebum production.
- Age: As we age, sebum production naturally slows down. This is why many people who had oily skin in their youth find they have dry or normal skin as they enter their 50s and 60s.
- Lifestyle: Stress can trigger a cortisol spike, which often leads to increased oil production and breakouts.
Conclusion
Understanding that your skin type is determined by how oily or dry the skin is allows you to stop guessing and start caring for your complexion with intention. Whether you are managing the shine of oily skin or the delicate tightness of a dry complexion, the key is balance and consistency. By choosing phyto-aromatic formulas that respect your skin's biology, you aren't just applying a product—you are engaging in a daily ritual of self-care.

FAQ
Can my skin type change from oily to dry?
While your genetic "blueprint" remains the same, your skin type can shift over time due to aging and hormonal changes. Most people experience a decrease in sebum production as they get older, meaning someone who had oily skin in their 20s may find their skin becomes normal or even dry in their 50s.
How do I know if my skin is dry or just dehydrated?
Dry skin is a type characterized by a lack of oil (sebum), whereas dehydrated skin is a temporary condition caused by a lack of water. If your skin feels tight but still looks shiny or breaks out, it is likely dehydrated oily skin; if it is flaky, lacks shine entirely, and has very small pores, it is likely a dry skin type.
Should I use the same products in summer and winter?
Because environmental factors like humidity and temperature affect how your skin behaves, it is often helpful to adjust your ritual. You might use a lighter fluid like Nude Perfect Fluide in the humid summer and switch to a richer cream like Hydra n°1 Crème in the dry winter to provide extra protection.
Is sensitive skin a real skin type?
In the professional world, sensitivity is often viewed as a condition that can affect any skin type, though it is most common in dry skin. It is characterized by a compromised barrier that reacts easily to external triggers, requiring soothing botanical ingredients like those found in our sensitive skin approach.
