Introduction
There is a particular frustration that comes with having a complexion that feels greasy to the touch yet tight, flaky, and uncomfortable underneath. If you find yourself wondering why your oily skin becomes dry in winter, you are experiencing one of the most common seasonal skin paradoxes: dehydration in an oily skin type. The biting winds and parched indoor air of the colder months strip essential moisture from the surface, leaving your skin struggling to maintain its equilibrium.
At Yon-Ka Paris, we understand that oily skin requires a delicate balance—especially when the environment turns harsh. This guide will explore the biological reasons behind winter dryness, the difference between oil and water in the skin, and how to adapt your phyto-aromatic ritual to restore comfort without clogging pores. If you want a wider routine built for this skin type, start with our products for oily and combination skin and build from there.
The Difference Between Oily and Dehydrated Skin
The first step in resolving winter skin woes is understanding that oil and water are not the same thing. Many people use the terms "dry" and "dehydrated" interchangeably, but in the world of professional skincare, they describe two very different issues.
Oily skin is a skin type determined by your genetics and the activity of your sebaceous glands. If you have oily skin, your pores naturally produce an abundance of sebum (oil). Dry skin is also a skin type, but one that lacks natural lipids or oils. Dehydrated skin, however, is a condition that can affect any skin type—including oily skin. It occurs when there is a lack of water in the stratum corneum, the outermost layer of the epidermis.
When your oily skin feels "dry" in the winter, it is almost certainly dehydrated. You may notice your face looks shiny or even breaks out, yet it feels "small" for your face, looks dull, and shows fine lines more prominently. This happens because your skin's moisture barrier has been compromised, allowing water to evaporate while oil production remains high (or even increases to compensate for the lack of water). For more guidance on balancing hydration without heaviness, our dry and dehydrated skin collection is a helpful place to look next.
Why the Winter Environment Triggers Dryness
Winter presents a "perfect storm" of conditions that deplete the skin’s water reserves. Understanding these external triggers helps us realize why our summer skincare routine suddenly feels inadequate.
Low Humidity and Transepidermal Water Loss
The air in winter, both outdoors and indoors, is significantly less humid than in the summer. Cold air holds less moisture, and central heating systems further dry out the environment. This creates a "osmotic pull," where the dry air literally sucks moisture out of your skin through a process called Transepidermal Water Loss (TEWL).
The Barrier Function Weakens
Your skin barrier is like a brick wall where your skin cells are the bricks and lipids (fats) are the mortar. In winter, the lack of environmental moisture can cause this "mortar" to become brittle. For those with oily skin, this often leads to a compromised barrier that can no longer hold onto water, even if it is still producing plenty of oil.
Temperature Fluctuations
Moving from the freezing outdoor air into a heated building causes the capillaries in the skin to rapidly contract and expand. This constant "thermal shock" can lead to increased sensitivity and redness. For oily skin types, this irritation often manifests as rough, flaky patches on top of an otherwise oily T-zone.
Quick Answer: Oily skin becomes dry in winter because cold air and indoor heating cause water to evaporate from the skin, a process known as Transepidermal Water Loss (TEWL). This leads to dehydration—a lack of water—even while the skin continues to produce oil, resulting in a complexion that feels tight and oily at the same time.

Internal Factors: Hormones, Stress, and Diet
While the weather is the primary culprit, internal factors during the winter months can exacerbate the feeling of dryness and lead to unexpected breakouts.
Holiday stress often leads to an increase in cortisol, a hormone that can stimulate the sebaceous glands to produce even more oil. This is why you might experience "winter acne" alongside dry, flaky patches. Additionally, winter diets—often higher in sugar and dairy—can influence inflammation levels in the skin.
Hydration starts from within, but it doesn't end there. While drinking water is essential for your overall health, it is the last place to reach the skin's surface. This is why topical hydration and barrier protection are non-negotiable during the winter months. Incorporating foods rich in Omega-3 fatty acids, like walnuts or flaxseeds, can help support the skin's lipid barrier from the inside out.
Rethinking the Cleansing Step
The biggest mistake those with oily skin make in winter is continuing to use harsh, foaming, or "deep-cleansing" washes. If your skin feels "squeaky clean" or tight after washing, you are stripping away the very moisture you are trying to preserve.
In the winter, we recommend switching to a more supportive cleansing method. Lait Nettoyant, our iconic cleansing milk, is an excellent choice even for oily skin types during the cold months. It effectively removes makeup and impurities while respecting the skin's hydrolipidic film.
Key Takeaway: Avoid hot water when cleansing. While a steaming shower feels wonderful in January, hot water melts away the skin’s natural protective oils, leading to immediate dehydration. Stick to lukewarm water to keep the skin barrier intact.
The Power of the Phyto-Aromatic Mist
In the Yon-Ka ritual, the toning step is never about "astringency" or stripping the skin. Instead, it is about infusion. Our Lotion Yon-Ka PNG is a phyto-aromatic healing water that is essential for treating winter dehydration.
For normal to oily skin types, Lotion Yon-Ka PNG provides a refreshing boost of our signature Quintessence. This blend of lavender, geranium, rosemary, cypress, and thyme essential oils helps to balance the appearance of oil while immediately soothing the tightness of dehydration.
By misting the skin before applying your serum or moisturizer, you are trapping that hydration against the skin, allowing subsequent products to absorb more effectively. This creates a "hydration sandwich" that is vital for preventing TEWL during the day.
Targeted Hydration for Oily Skin
When choosing a moisturizer for oily skin in winter, the goal is to find "water-light" formulas that provide intense hydration without heavy, occlusive oils that might cause congestion.
The Role of Hyaluronic Acid
Hyaluronic acid is a powerhouse ingredient for winter. It is a humectant, meaning it can hold up to 1,000 times its weight in water. For oily skin, it provides the necessary "drink of water" without the weight. Our Hydra N°1 Serum is specifically designed for this purpose.
Balancing with a Lightweight Fluid
If you prefer a moisturizer that hydrates while keeping shine in check, Hydra N°1 Fluide is a lightweight option that fits an oily-yet-dehydrated winter complexion.
The Importance of Gentle Exfoliation
When oily skin becomes dehydrated, dead skin cells don't shed as easily as they should. They "glue" themselves to the surface, creating a dull appearance and potentially clogging pores. However, using harsh scrubs or strong acid peels in winter can further damage a fragile barrier.
Gommage Yon-Ka is our unique, grain-free exfoliator that is ideal for this delicate situation. It is a botanical peel that you "roll" off the skin with your fingertips. It gently removes dead cells and clarifies the complexion without the irritation of physical scrubbing. This ensures your hydrating serums can actually reach the living cells of the skin rather than sitting on top of a layer of dry, dead cells.
Weekly Rituals: The Hydrating Mask
In the winter, a weekly hydrating mask is not a luxury—it is a necessity. Even for oily skin, a dedicated moisture mask can "reset" the skin’s hydration levels.
Hydra N°1 Masque is designed to provide intense, timed-release hydration. You can apply it once or twice a week, or even use it as a thin layer overnight if your skin is feeling particularly parched. This helps to repair the appearance of the barrier while you sleep, ensuring you wake up with skin that feels supple rather than tight.
Step 1: Cleanse with a gentle milk like Lait Nettoyant to preserve natural lipids. Step 2: Mist generously with Lotion Yon-Ka PNG to infuse the skin with aromatic hydration. Step 3: Apply a targeted serum like Hydra N°1 Serum to deliver water deep into the epidermis. Step 4: Seal it in with a lightweight moisturizer like Hydra N°1 Fluide. Step 5: Protect the skin with an oil-free SPF, as UV rays still contribute to barrier damage in winter.
Protecting the Skin Barrier with Lipids
While we focus heavily on water (hydration), sometimes winter oily skin needs a tiny bit of the "right" lipids to stay healthy. If your skin is flaking or red, it means the "mortar" of your barrier is truly broken.
In these cases, the right ingredients matter. Learn more about the botanicals and actives behind our formulas on Our Ingredients. You can use a few drops of a nourishing booster with your usual moisturizer when your skin needs extra comfort.
A Note on Essential Oil Safety
Most of our formulations feature the Yon-Ka Quintessence, a 100% natural complex of five essential oils. When introducing these active botanicals, we recommend a simple patch test on your inner forearm for 24 hours. While a slight, fleeting tingling sensation can be a normal sign of the essential oils at work, any persistent redness means you should reduce frequency.
Professional Care for Seasonal Transitions
Sometimes, at-home care needs a professional boost to overcome the stubborn dryness of winter. A professional facial at a Yon-Ka partner spa can provide deep, specialized hydration that is difficult to achieve alone.

FAQ
Why is my skin so oily but also flaky in the winter?
This is a classic sign of dehydration. Your skin lacks water (causing the flakes and tightness), but it is still an oily skin type (causing the sebum production). The flakes are often dead skin cells that cannot shed properly because the skin is too dry to perform its natural exfoliation process.
Should I stop using acne treatments if my skin feels dry?
You don't necessarily need to stop, but you should likely reduce their frequency. Many acne treatments, like salicylic acid or benzoyl peroxide, can be drying. Try using them every other day and always follow with a hydrating serum like Hydra N°1 Serum to prevent your skin barrier from becoming overwhelmed.
Can I use a face oil if I have oily skin?
Yes, as long as it is a high-quality, non-comedogenic oil. Lightweight botanical oils can actually help "tell" your skin it has enough protection, which may slow down its own overproduction of sebum. A nourishing booster can be helpful when your skin needs extra comfort.
Is it okay to skip moisturizer if my face feels greasy?
No, skipping moisturizer will actually make the problem worse. When you skip moisturizer, your skin perceives a lack of protection and will often produce more oil to compensate. The key is to use a lightweight, water-based formula like Hydra N°1 Fluide that provides hydration without adding heaviness.
