Makeup that does not adhere well, makeup that becomes greasy during the day, or habitually carrying oil-blotting sheets are all warning signs of “very oily skin and large pores.” These issues are not only frustrating but can also lead to clogged pores, inflammatory acne, and dull skin. Many people try to address them by washing their face frequently or using products that leave the skin dry and tight. Scientifically, however, this damages the skin and can stimulate even more oil production. This article explores the mechanisms behind facial oil production and medically grounded ways to address it, helping restore smooth, balanced skin.
What Is Oily Skin?
Oily skin, or seborrhea, is a condition in which the sebaceous glands beneath the skin are overactive and produce excessive amounts of oil, or sebum, that coat the face. Although sebum helps retain moisture and protect the skin from pollution, too much can make the face look shiny and is a major reason pores enlarge to release the excess oil.
What Causes Oily Skin?
Facial oiliness is not caused by hot, humid weather alone. Other bodily mechanisms and environmental factors can accelerate oil production, including the following:
- Genetics: If oily skin runs in the family, it is often inherited. People with oily skin commonly have overactive 5-alpha reductase, an enzyme that directly stimulates the sebaceous glands.
- Sex hormones: Androgens, particularly testosterone, are the primary hormones that signal sebaceous gland cells, or sebocytes, to produce more oil. This is why the skin tends to become oilier and more prone to acne during adolescence or before menstruation.
- Temperature and environment: Research has found that every 1°C increase in temperature raises facial oil production by approximately 10%.
- Diet: Eating foods with a high glycemic index and consuming dairy products stimulate IGF-1 (Insulin-like Growth Factor 1), which causes the sebaceous glands to produce more oil.
Can Oily Skin Also Be Caused by Dehydration?
Yes, it can. Medically, this condition occurs when the Skin Barrier is weakened, leading to substantial Transepidermal Water Loss (TEWL). When the upper layer of the skin, or epidermis, lacks water, the brain activates a compensatory mechanism that stimulates the sebaceous glands to produce a heavy layer of oil to reduce water evaporation. This results in a condition known as “Dehydrated Oily Skin,” in which the surface is greasy while the skin feels dry and tight underneath.
How Is Oily Skin Different from Other Skin Types?
Understanding the differences between skin types is important for choosing the right care.
- Oily Skin vs Dry Skin: Oily skin results from excessive sebum production, making the skin look shiny and the pores appear large. Dry skin lacks natural lipids and water, resulting in peeling, flaking, and very small pores.
- Oily Skin vs Combination Skin: Oily skin appears shiny across the entire face—the forehead, nose, chin, and cheeks. Combination skin is oily only in the T-Zone, covering the forehead and nose, while the U-Zone, or cheeks, is dry or normal.
- Oily Skin vs Normal Skin: Normal skin has a healthy balance of water and oil, known as homeostasis. Its pores appear refined, and it is neither excessively dry nor oily.
Common Problems Experienced by People with Very Oily Skin
When the face has more oil than it needs, other skin problems often follow in a domino effect, including:
- Comedonal and inflammatory acne: Excess oil combines with dead skin cells and clogs the pores, creating an ideal food source for C. acnes (Cutibacterium acnes) bacteria and leading to inflammation.
- Large pores: When the sebaceous glands produce large amounts of oil, the pores must enlarge to provide a passage for it. The longer this continues, the more elasticity the pores lose.
- Dull skin during the day: When secreted oil comes into contact with oxygen in the air, oxidation occurs, making the face look less vibrant and duller.
- Makeup that does not last: Oil breaks down cosmetics, causing makeup to look greasy, streak, or collect in patches during the day.
12 Ways to Address Very Oily Skin and Large Pores
Addressing very oily skin and large pores requires changes in daily habits and the right skincare choices, as follows:
1. Wash Your Face Only Twice a Day
Wash your face morning and evening with a gentle cleanser. Washing too frequently can stimulate the skin to produce more oil in compensation.
2. Exfoliate with BHA
Salicylic Acid (BHA) is oil-soluble, allowing it to penetrate deeply and clear oil clogging the pores.
3. Hydrate with a Lightweight Moisturizer
Choose a Gel or Lotion labeled Oil-Free and Non-Comedogenic to help prevent skin dehydration.
4. Apply Oil-Control Sunscreen
Sun exposure damages collagen, making pores appear larger. Choose a matte or water-based sunscreen that contains no oil.
5. Use Niacinamide (Vitamin B3)
It helps reduce oil production, refine pores, and strengthen the Skin Barrier.
6. Avoid Products with High Concentrations of Alcohol
Alcohol temporarily makes the skin feel dry and tight, but heavier oil production follows later.
7. Blot Your Face Correctly
Gently press oil-blotting sheets only onto particularly oily areas, such as the T-Zone. Do not use them more than twice a day, and never rub them across the skin.
8. Apply a Clay Mask
Ingredients such as Kaolin or Bentonite help absorb excess oil and impurities from the pores. Use a clay mask 1–2 times per week.
9. Drink Enough Water
Drinking 8–10 glasses of water a day helps maintain hydration balance from within and reduces the risk of dehydrated skin.
10. Avoid Foods High in Sugar and Fat
Reduce sweets, refined carbohydrates, and cow’s milk products to limit stimulation of the hormones that make the sebaceous glands work harder.
11. Manage Stress
Stress stimulates the hormone Cortisol, which signals the skin to produce more oil.
12. Consider Medical Technology
Chemical Peeling treatments or lasers, such as the Pico Laser, at The Vanish Clinic can help regulate sebaceous gland activity and stimulate collagen to visibly tighten pores quickly.
Natural Ways to Care for Very Oily Skin
Adapting your skincare routine appropriately is the key to controlling oil over the long term.
- Always Double Cleanse: Even if you do not wear makeup, use Cleansing Water or Cleansing Balm before washing with a foaming cleanser whenever you wear sunscreen.
- Avoid Harsh Facial Scrubs: Aggressively rubbing the face with exfoliating particles can trigger inflammation and thin the skin, causing the sebaceous glands to work harder.
- Use Fewer Skincare Layers: There is no need for an elaborate 5–6-step skincare routine. Start with a facial essence, then apply serum and moisturizer, followed by sunscreen in the morning.
- Change Your Pillowcase Regularly: Oily facial skin often leaves oil residue on pillowcases, which can become a breeding ground for bacteria. Change your pillowcase at least once a week.
- Give Your Skin an Occasional Break from Makeup: On days off, allow your pores to breathe by applying only moisturizer and sunscreen.
What Type of Cream Is Best for Very Oily Skin?
People with oily skin should pay particular attention to the Active Ingredients listed on product packaging. Creams containing the following ingredients are especially suitable for oily skin:
- Salicylic Acid (BHA): A star ingredient for oily skin, it deeply dissolves oil clogging the pores, exfoliates the skin, and reduces acne formation.
- Zinc PCA: A compound known for regulating sebum, reducing acne-causing bacteria, and maintaining moisture balance.
- Niacinamide: A multifunctional form of Vitamin B3 that helps reduce the appearance of pores, control excess oil, and fade dark marks and redness from acne
- Hyaluronic Acid: An excellent skin hydrator that helps retain moisture without adding oil, leaving the skin plump and reducing dehydrated oiliness.
- Retinol (Vitamin A): In a serum or night cream, it helps accelerate skin-cell turnover, regulate oil production, and stimulate collagen so pores appear smaller.
Article Summary
Very oily skin and large pores are skin conditions with causes that go beyond cleanliness, including genetics, hormones, and dehydration. Proper care therefore does not mean trying to wipe or wash away all oil. Instead, it involves using skincare that helps maintain balance, such as BHA and Niacinamide, together with appropriate hydration. If changing your habits does not produce results, consulting a specialist or receiving standardized treatment and laser services can be an effective, targeted option.

Frequently Asked Questions (FAQ)
Is It True That Very Oily Skin Is Prone to Acne?
Yes. Excess facial oil, or sebum, mixes with dead skin cells and impurities, making it easier for pores to become clogged. This oxygen-deprived, lipid-rich environment is an ideal breeding ground for C. acnes bacteria, which can then cause inflammatory acne.
Does Very Oily Skin Really Cause Large Pores?
Yes. When the sebaceous glands produce large quantities of oil, the pores—which act like channels for the oil—must expand to release it onto the skin’s surface. If the skin has also lost collagen, the pores will appear even larger and may not contract on their own.
Is Very Oily Skin Hereditary?
Genetics play a major role. The size and activity of the sebaceous glands are often genetically determined. If the parents have oily skin and large pores, their children are highly likely to have the same skin type and may also be more sensitive than usual to androgen hormones.
Can Oily Skin Go Away?
Genetically oily skin cannot be permanently “cured” or transformed into dry skin. However, it can be controlled and managed so the skin remains balanced and looks like normal skin through appropriate skincare, behavioral changes, and medical procedures.
Does Frequent Face Washing Help Very Oily Skin?
No, and it can be highly damaging. Washing the face more than twice a day, particularly with a harsh foaming cleanser, strips away the natural oils that form the Lipid Barrier and leaves the skin dry and tight. The body then signals the sebaceous glands to produce even more replacement oil, making the face become oily more quickly.
