Introduction
Waking up to a healthy glow is a universal skincare goal, but for many, that glow can quickly transition into an unwanted midday shine. Dealing with an oily complexion often feels like a constant battle against blotting papers and persistent congestion. Understanding what cause oily skin on face is the first step toward reclaiming a balanced, matte, and radiant appearance. At Yon-Ka Paris, we believe that oily skin isn't a problem to be "stripped" away, but a delicate ecosystem that requires harmony and the right botanical support. This article explores the biological, environmental, and lifestyle factors that trigger excess sebum production and provides a professional roadmap for achieving a refined, healthy-looking complexion. By shifting from aggressive treatments to a supportive, phyto-aromatic ritual, you can transform your relationship with your skin.
Quick Answer: Oily skin is primarily caused by overactive sebaceous glands producing excess sebum. This is often triggered by genetic predispositions, hormonal fluctuations (particularly androgens), environmental factors like humidity, and even using skincare products that are too harsh, which causes the skin to overcompensate by producing more oil.
The Biology of Sebum: Why Your Skin Produces Oil
To understand what cause oily skin on face, we must first look at the sebaceous glands. These tiny glands are located all over the body, with the highest concentration found on the face and scalp. Their primary job is to produce sebum, a complex mixture of lipids (fats) that creates a protective barrier on the skin's surface.
Sebum is actually essential for skin health. It helps to seal in moisture, maintain the skin's elasticity, and provide a defense against environmental stressors. However, when these glands become overactive, the result is an oily complexion, enlarged pores, and a higher likelihood of occasional blemishes.
The "T-zone"—the forehead, nose, and chin—is typically the oiliest part of the face because it contains the highest density of sebaceous glands. When the production cycle goes into overdrive, the excess oil can mix with dead skin cells and debris, leading to a heavy or "suffocating" feeling on the skin.
Common Biological Factors That Cause Oily Skin
While everyone has sebaceous glands, not everyone experiences an oily complexion. Several internal factors dictate the activity level of these glands.
Genetics and Heredity
Genetics play a significant role in determining your skin type. If your parents or siblings have oily skin, you are much more likely to have larger sebaceous glands that produce more oil. You cannot change your genetic makeup, but knowing that your skin is biologically predisposed to oiliness allows you to choose products specifically designed to manage it.
Hormonal Fluctuations
Hormones are perhaps the most powerful internal trigger for oil production. Androgens, often referred to as "male" hormones (though present in both men and women), are responsible for stimulating the sebaceous glands. When androgen levels rise—during puberty, menstrual cycles, pregnancy, or periods of high stress—sebum production often follows suit.
This is why many people experience "hormonal breakouts" or increased oiliness during specific times of the month. As we age, our hormone levels shift. While many people find their skin becomes drier in their 40s and 50s, hormonal shifts during perimenopause can sometimes lead to a temporary increase in oiliness.
Age and Skin Evolution
While oily skin is most common in teenagers and young adults, it can persist well into adulthood. Interestingly, as we age, our skin's protein structure (collagen and elastin) begins to change. While the skin might produce less oil over time, the appearance of enlarged pores can make the skin look oilier than it actually is.
Environmental and Lifestyle Influences
Beyond your biology, the world around you and your daily habits can significantly impact how much oil your face produces throughout the day.
Climate and Humidity
Heat and high humidity are major external factors that cause oily skin on the face. In hot environments, the sebaceous glands are stimulated to produce more oil, while sweat can make that oil feel even heavier on the skin. Conversely, in cold, dry winter months, the skin can become dehydrated, which may ironically lead to a "rebound" effect where the skin produces more oil to compensate for the lack of moisture.
Diet and Internal Wellness
While the link between diet and oily skin is still being studied, many skincare professionals observe that diets high in refined sugars and dairy may influence sebum production. High-glycemic foods cause a spike in insulin, which can trigger androgen activity and, subsequently, more oil. Staying hydrated by drinking plenty of water helps maintain the skin’s overall balance, though it does not "flush out" oil directly.
Stress and Cortisol
When you are under stress, your body produces cortisol, the primary stress hormone. Cortisol has a direct relationship with the sebaceous glands. Higher stress levels often lead to higher oil production, which is why a stressful week at work is often followed by a shiny T-zone and unwanted congestion.
Key Takeaway: Oily skin is a result of a complex interplay between your DNA, your hormones, and your environment. While you cannot control your genetics, you can manage how your skin responds to external triggers through a consistent, balancing ritual.
How Your Skincare Routine Might Be Contributing
One of the most surprising things that cause oily skin on face is the very skincare routine intended to fix it. Many people with oily skin fall into the trap of using products that are too aggressive.
The "Squeaky Clean" Myth
If you use harsh, foaming cleansers or alcohol-heavy toners, you may feel an immediate sense of relief as the oil is stripped away. However, this is temporary and counterproductive. Stripping the skin's natural moisture barrier signals to the brain that the surface is dry and unprotected. In response, the sebaceous glands go into emergency mode, producing even more oil to replace what was lost. This is known as the "rebound effect."
To avoid this, we recommend a gentle, barrier-respecting cleanser like Lait Nettoyant. This cleansing milk gently lifts impurities without disrupting the skin's delicate pH balance, ensuring the skin feels soft rather than stripped.
Skipping Moisturizer
It is a common misconception that oily skin does not need moisturizer. In reality, oily skin can still be dehydrated (lacking water). When oily skin lacks water, it looks dull and can feel tight, yet still remain shiny. Using a lightweight, non-comedogenic moisturizer is essential for "telling" the sebaceous glands that the skin is sufficiently hydrated, which can help slow down oil production over time.
Over-Exfoliating
While exfoliation is necessary to keep pores clear, doing it too often can irritate the skin and trigger excess oil. Using a gentle, grain-free exfoliator like Gommage Yon-Ka once or twice a week is a much safer way to refine the skin's texture without causing the inflammation that leads to more sebum.
A Phyto-Aromatic Approach to Balancing Oily Skin
At Yon-Ka, we believe in the power of plants to bring the skin back into a state of equilibrium. Our approach to oily skin focuses on purifying, balancing, and hydrating rather than stripping or drying.
The foundation of our formulas is the Quintessence. This exclusive complex consists of five essential oils—lavender, geranium, rosemary, cypress, and thyme. This 100% natural and active blend is particularly beneficial for oily skin:
- Lavender provides a soothing effect.
- Rosemary and Thyme offer purifying properties.
- Geranium helps to balance the appearance of sebum.
- Cypress acts as a natural astringent to refine the look of pores.

The Importance of the Mist
After cleansing, the next step in a professional ritual is a phyto-aromatic mist. For those with oily skin, Lotion Yon-Ka PNG is an essential step. This alcohol-free mist uses the power of the Quintessence to tone and energize the skin, preparing it to absorb subsequent treatments more effectively. It provides an immediate sensation of freshness and helps to regulate the appearance of shine throughout the day.
Building a Ritual to Manage Excess Oil
A consistent daily routine is the most effective way to address the factors that cause oily skin on the face. Here is a recommended ritual for a balanced, matte complexion.
Step 1: Gentle Cleansing
Morning and night, use a gentle cleanser. If you wear makeup or sunscreen, a double cleanse in the evening ensures that all debris is removed. Lait Nettoyant is excellent for this, as it respects the skin’s integrity while thoroughly cleaning.
Step 2: Tone and Prepare
Mist your face with Lotion Yon-Ka PNG. This helps to rebalance the skin and provides a layer of botanical hydration. Press the mist into the skin with your hands to enhance its revitalizing effects.
Step 3: Targeted Treatment
If you are dealing with persistent shine or the appearance of enlarged pores, a targeted treatment can help. Crème PG is a specialty cream designed specifically for oily skin types. It contains botanical extracts that help to mattify the skin and balance the look of the T-zone.
Step 4: Hydration and Protection
During the day, choose a lightweight moisturizer that offers a "blurring" or mattifying effect. Nude Perfect Fluide is an ideal choice for oily skin. It acts as a complexion perfector, helping to minimize the look of pores and control shine while protecting the skin from environmental pollutants.
For nighttime, consider a revitalizing cream like Vital Defense. This cream is rich in botanical ingredients that help to support the skin while you sleep, so you wake up with a more refined complexion.
Note: When introducing new products containing active botanical extracts and essential oils, we always recommend a patch test. Apply a small amount to your inner forearm and wait 24 hours to ensure your skin responds beautifully.
Professional Solutions for Oily Skin
While home care is vital, professional treatments can provide a deeper level of purification. A professional esthetician can perform expert extractions and apply high-concentration botanical masks that are difficult to replicate at home.

Myth vs. Fact: Oily Skin Edition
There is a lot of misinformation regarding oily skin. Let's clarify some of the most common myths.
Myth: Oily skin doesn't need anti-aging products. Fact: While sebum can help keep the skin's surface hydrated, it does not prevent the breakdown of collagen and elastin caused by age and UV exposure. People with oily skin should still use antioxidant-rich products like Vital Defense to protect against environmental aging.
Myth: Sun exposure dries up oily skin and helps clear it. Fact: While the sun may seem to dry out oil initially, it actually damages the skin barrier and causes dehydration. This triggers the skin to produce even more oil later on. Furthermore, UV damage can cause pores to lose their elasticity, making them appear larger. Always use a non-comedogenic sunscreen.
Myth: You should wash your face more than twice a day if it's oily. Fact: Washing too frequently can lead to irritation and the "rebound effect" mentioned earlier. Stick to a morning and evening cleanse, and use a mist like Lotion Yon-Ka PNG for a midday refresh if needed.
Consistency is the Key to Balance
Addressing what cause oily skin on face is not a one-time fix. Because sebum production is influenced by ongoing factors like hormones and genetics, the goal is management and balance rather than "elimination."
By following a ritual that focuses on gentle purification and botanical hydration, you can help your skin reach a state where it looks clear, matte, and healthy.

FAQ
Can I use face oils if I have oily skin?
Yes, but you must choose the right ones. Non-comedogenic oils that are high in linoleic acid can actually help balance the skin's own sebum; however, it is often better to use an "oil-in-serum" like Serum Omega if your skin is feeling particularly compromised or dehydrated.
Why is my skin oily but also flaky?
This is a classic sign of dehydrated oily skin. Your sebaceous glands are producing oil, but your skin cells lack water, causing them to become dry and flake off. Focus on increasing hydration with products like Hydra N°1 Fluid rather than using more oil-stripping cleansers.
Does makeup cause oily skin?
Makeup itself doesn't typically cause the glands to produce more oil, but certain "heavy" or comedogenic foundations can trap oil and sweat against the skin, leading to congestion. Look for "oil-free" or "mattifying" labels, and always ensure you thoroughly remove makeup at the end of the day.
How long does it take to see a difference in my oily skin?
When you switch to a more balanced, gentle ritual, it can take about 28 days—the length of a full skin-cell turnover cycle—to see a noticeable difference. Initially, your skin may take a week or two to adjust as it stops overcompensating for the harsh products you may have used in the past.
