Introduction
Waking up to a complexion that feels fresh and balanced is a universal skincare goal. However, for many, that morning glow quickly transitions into an unwanted midday shine. Understanding what causes oily skin on your face is the first step toward reclaiming a matte, refined, and healthy-looking complexion. While excess oil can be frustrating, it is important to remember that sebum—the natural oil your skin produces—serves a vital purpose in protecting and hydrating your skin barrier. At Yon-Ka Paris, we believe that managing oily skin is not about "stripping" the skin bare, but about restoring its natural harmony through botanical expertise. This article explores the biological, environmental, and lifestyle factors behind oil production and how a dedicated phyto-aromatic ritual can help balance your skin’s appearance.
Quick Answer: Oily skin is primarily caused by overactive sebaceous glands producing excess sebum. This can be triggered by genetic predispositions, hormonal fluctuations, environmental humidity, and even skincare mistakes like over-cleansing, which causes the skin to overcompensate for lost moisture.
The Biological Foundation of Sebum
To understand why your skin becomes oily, we must first 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 coats the skin's surface.
Sebum is actually essential for skin health. It creates a protective film that helps lock in moisture and shields the skin from environmental stressors. However, when these glands become overactive, they produce more oil than the skin needs. This excess oil can collect in the pores, leading to a shiny appearance, a heavy or "greasy" feel, and a higher likelihood of congested pores and blemishes.
The density of sebaceous glands is highest on the face, particularly in the T-zone (the forehead, nose, and chin). This is why most people notice the most significant shine in these specific areas. When we talk about what causes oily skin on the face, we are really talking about the factors that send these glands into overdrive.
Genetic Predisposition and Heredity
One of the most common causes of oily skin is simply genetics. If one or both of your parents have oily skin, you are significantly more likely to have overactive sebaceous glands as well.
Genetics determine the size of your pores and the baseline activity level of your glands. Larger pores generally correlate with higher oil production because the pore provides more space for the sebum to flow onto the surface. While you cannot change your genetic makeup, knowing that your skin type is hereditary can help you shift your focus from "curing" the oiliness to "managing" it with consistent, balancing care.
The Role of Hormonal Fluctuations
Hormones are powerful chemical messengers that dictate many of our body’s functions, including skin behavior. Androgens, often referred to as "male" hormones although they are present in everyone, are the primary drivers of sebum production.
- Puberty: This is the most well-known period for oily skin. During adolescence, androgen levels spike, causing sebaceous glands to enlarge and produce significantly more oil.
- Menstrual Cycles: Many women notice a surge in oiliness and "period breakouts" during the week leading up to their period. This happens as progesterone levels rise, which can stimulate sebum production and cause pores to appear more prominent.
- Pregnancy and Menopause: Major hormonal shifts during these life stages can either increase or decrease oil production, depending on the individual’s unique hormonal balance.
- Stress Levels: When you are under stress, your body releases cortisol. This "stress hormone" has a direct link to sebaceous glands, often triggering them to produce more oil. This explains why high-stress periods often coincide with a shinier complexion and unexpected blemishes.
Environmental and Seasonal Factors
Your surroundings play a significant role in how your skin behaves. Heat and humidity are two of the most impactful external triggers for oily skin.
In hot, humid climates, the skin’s sebaceous glands are stimulated to produce more surface oil. Additionally, sweat can mix with excess sebum, creating a thick film on the skin that feels heavy and contributes to clogged pores. Conversely, you might notice that your skin feels more balanced during the winter months when the air is cooler and drier.
Air pollution is another modern factor. Microscopic pollutants can settle on the skin and mix with sebum. This not only makes the skin look duller but can also lead to oxidative stress, which may further disrupt the skin’s natural balance. Protecting the skin with antioxidant-rich formulas, like our Vital Defense day cream, can help shield the skin from these environmental aggressors.
Common Skincare Mistakes That Increase Oil
Ironically, many people who struggle with oily skin accidentally make the problem worse by using products that are too aggressive. This is often referred to as the "rebound effect."
Over-Cleansing and Stripping the Skin
When the face feels greasy, the natural impulse is to wash it with harsh, foaming cleansers or use alcohol-based toners to "dry out" the oil. However, when you strip the skin of its natural lipids, you damage the moisture barrier.
The skin perceives this dryness as a threat and sends a signal to the sebaceous glands to produce more oil to compensate for the loss. This creates a vicious cycle: the more you strip, the oilier your skin becomes. This is why we recommend gentle, barrier-respecting cleansers like Lait Nettoyant, which cleanses without disrupting the skin's delicate balance.
Skipping Moisturizer
A common myth is that oily skin doesn't need moisturizer. In reality, oily skin can still be dehydrated. Dehydration refers to a lack of water, not oil. When oily skin lacks water, it can actually look shinier and feel more uncomfortable.
Using a lightweight, non-comedogenic moisturizer (one that won't clog pores) is essential. Formulas like Nude Perfect Fluide provide the necessary hydration while maintaining a matte finish, helping the skin feel balanced and supple rather than greasy.
Myth: Using face oil will make oily skin worse. Fact: Using the right high-quality botanical oils can actually help "dissolve" excess sebum and signal to your skin that it has enough moisture, potentially slowing down natural oil production.
Dietary Influences on Skin Oil
While topical care is vital, what you put into your body can influence the appearance of your skin. Research suggests that high-glycemic diets—those rich in refined sugars and white flours—can cause spikes in insulin.
Increased insulin levels can stimulate the production of androgens, which, as we established earlier, are the hormones responsible for oil production. Reducing the intake of sugary snacks, sodas, and processed breads in favor of whole grains, lean proteins, and leafy greens may help support a clearer, more balanced complexion from the inside out.
How to Manage Oily Skin the Yon-Ka Way
At Yon-Ka, we approach oily skin through the lens of phyto-aromatic therapy. Our goal is never to "strip" the skin, but to use the power of plants to purify, balance, and refine the skin's appearance.
The heart of our formulas is the Quintessence—a proprietary blend of five essential oils: lavender, geranium, rosemary, cypress, and thyme. These botanical actives work in synergy to provide purifying and soothing benefits that are particularly effective for oily and combination skin types. You can learn more about this signature blend on our ingredients page.
The Balancing Ritual
To manage what causes oily skin on the face, consistency is key. A balanced ritual should focus on gentle purification and lightweight hydration.
- Cleanse: Use a gentle cleansing milk like Lait Nettoyant morning and night. This ensures that makeup, impurities, and excess oil are removed without triggering the "rebound effect."
- Tone: A phyto-aromatic mist is a crucial step. Our Lotion Yon-Ka PNG (formulated specifically for normal to oily skin) contains our signature Quintessence to help balance the appearance of oil and prepare the skin for the next steps.
- Exfoliate: Regular, gentle exfoliation is necessary to prevent excess oil from trapping dead skin cells in the pores. Gommage Yon-Ka is a grain-free, botanical peel that clarifies the skin's appearance without irritation.
- Treat: Incorporate targeted treatments like Masque 103, which uses purifying clays to help clarify and refine oily skin.
- Moisturize & Mattify: During the day, a product like Nude Perfect Fluide can be a game-changer. It acts as a multi-perfecting fluid that blurs the appearance of pores and provides a long-lasting matte finish.
If you are still deciding which step to prioritize, our How to Choose the Right Serum for Your Skin guide can help you think through where a targeted treatment fits in your routine.

Key Takeaway: Oily skin is a dynamic condition influenced by both internal biology and external habits. The most effective way to manage it is through a gentle, consistent ritual that hydrates the skin while using botanical actives to regulate the appearance of oil.
Lifestyle Tips for a Matte Complexion
Beyond your skincare ritual, small lifestyle adjustments can make a significant difference in how much oil your face produces throughout the day.
- Clean Your Phone: Your phone screen carries bacteria and oil that can be transferred back to your face during calls, contributing to localized congestion.
- Change Pillowcases: Silk or cotton pillowcases absorb oil and sweat while you sleep. Changing them every few days helps keep your skin environment clean.
- Avoid Touching Your Face: The oils and dirt on your hands can disrupt your skin's balance and lead to breakouts.
- Use Blending Sponges and Brushes Carefully: Ensure your makeup tools are cleaned weekly to prevent the buildup of old sebum and bacteria.
- Check Your Hair Products: If you have oily skin and also struggle with forehead breakouts, your hair products (like oils or waxes) might be migrating onto your skin.
When to Consult a Professional
While most cases of oily skin can be managed with a proper skincare ritual and lifestyle changes, persistent issues may require medical advice. If you experience sudden, extreme changes in your skin's oil production, or if you have painful, cystic acne that does not respond to over-the-counter care, it is best to consult a dermatologist or physician. They can help determine if an underlying medical condition or hormonal imbalance requires a clinical approach.

FAQ
Why is my skin suddenly so oily?
A sudden increase in oiliness is often linked to hormonal shifts, increased stress levels, or a change in the environment, such as a move to a more humid climate. It can also be a "rebound effect" if you have recently started using harsh, drying skincare products that have compromised your skin's moisture barrier.
Does oily skin age slower?
There is some truth to this! Because sebum contains antioxidants and helps keep the skin's surface lubricated and hydrated, people with oily skin often develop fewer fine lines and wrinkles compared to those with very dry skin. However, oily skin is still susceptible to other signs of aging, such as loss of firmness and enlarged pores.
Should I wash my face more than twice a day if it's oily?
Generally, no. Washing your face more than twice a day can strip away the essential lipids your skin needs to stay healthy, leading to increased oil production as the skin tries to protect itself. If you feel very oily mid-day, try using a botanical mist like Lotion Yon-Ka PNG to refresh the skin rather than a full cleanse.
How do I know if my skin is oily or just dehydrated?
If your skin feels tight and "thirsty" but still looks shiny or has a greasy film, you are likely dealing with dehydration. Truly oily skin usually feels thick and supple, whereas dehydrated skin may show fine lines and feel uncomfortable despite the surface oil. A lightweight, hydrating fluid is the best way to address both concerns simultaneously.
