If your skin feels greasy by lunchtime, your makeup seems to slide off your face, or you find yourself constantly reaching for blotting paper, you’re not alone. Oily skin is a common concern, and while it’s often frustrating, it’s also entirely manageable once you understand what’s going on beneath the surface.
In this blog, we’ll break down the most common causes of oily skin, explore why your face might suddenly feel oilier than usual and share practical, science-backed tips to help bring your skin back into balance, without stripping it or triggering more shine.
What Causes Oily Skin?
Your skin naturally produces oil (called sebum) through the sebaceous glands. Sebum plays an important role in keeping the skin healthy and protected, but when these glands become overactive, it can result in an oily face, enlarged pores and a shiny appearance.
Here are some of the most common causes of oily skin:
- Hormonal fluctuations: Hormones, especially androgens, can increase oil production. This is often seen during puberty, menstruation, or stress.
- Genetics: If oily skin runs in your family, your sebaceous glands may naturally be more active.
- Hot, humid climates: Heat and humidity can increase oil flow, making skin appear shinier than usual.
- Over-cleansing: Stripping the skin with harsh cleansers can damage the skin barrier and trigger even more oil as your skin tries to compensate.
- Skin type: Some people simply have oilier skin than others; this is a normal variation in skin types.
It’s worth noting that a certain amount of oil is essential for maintaining a healthy skin barrier — the goal isn’t to eliminate it completely, but to keep it balanced.
If you’re asking, ‘Why is my face so oily?’, your skincare routine could be the cause — or the solution.
Why Is My Face So Oily All of a Sudden?
A sudden change in oiliness can catch you off guard. If your skin has recently become greasier than usual, one or more of these factors could be at play:
- Changes in your skincare routine: Using drying products, over-exfoliating, or skipping moisturiser can disrupt your skin’s natural balance.
- Increased stress: Elevated cortisol levels can stimulate oil production.
- Dietary changes: Diets high in sugar or dairy have been linked to increased sebum production in some people.
- Weather changes: Moving into a warmer season or climate can influence how much oil your skin produces.
Sometimes, increased oiliness is your skin’s way of signalling that its barrier is compromised. Rebuilding skin resilience with barrier-supportive ingredients is often a good starting point for bringing oil levels back into balance.
Oily Skin Myths Debunked
Before we jump into fixing oily skin, let’s clear up a few common misconceptions:
-
Myth: Moisturiser makes oily skin worse
Reality: Skipping moisturiser can actually make things worse. If your skin becomes too dry, it may produce even more oil to compensate. -
Myth: Scrubbing skin daily will reduce oil
Reality: Over-exfoliating can strip the skin, trigger irritation and lead to rebound oiliness. -
Myth: Oily skin doesn’t need a routine
Reality: Oily skin needs a thoughtful routine, not just oil-control products. Maintaining hydration and barrier support is key.
Climate, genetics and skincare choices all play a part in why your face might be oily, but balance is achievable.
How to Fix Oily Skin (Without Overdoing It)
Oily skin isn’t something to fight — it’s something to manage. With the right approach, you can reduce excess oil while keeping your skin healthy and comfortable.
1. Use the Right Cleanser
Choose a cleanser that removes excess oil without stripping your skin. Foaming or gel cleansers are often ideal, especially those containing ingredients like salicylic acid. The allmedic Active Cleanser is a great option for oily and acne-prone skin, helping to purify without disrupting your natural barrier.
2. Exfoliate Thoughtfully
Regular exfoliation helps keep clogged pores under control by removing dead skin cells that trap oil and debris. However, it’s important to avoid harsh scrubs or daily exfoliation. The allmedic Active Exfoliating Scrub offers a balanced approach with fine exfoliants that polish the skin’s surface while respecting skin health.
3. Support Your Skin Barrier
An impaired barrier often leads to excess oil production and sensitivity. Hydration and targeted repair help the skin regulate itself. The allmedic Skin Repair contains soothing ingredients designed to restore resilience and calm stressed skin.
4. Clarify Without Stripping
If your skin feels congested or looks dull, a lightweight lotion can help clarify and rebalance. The allmedic Detoxifying Skin Lotion is ideal for oily or breakout-prone skin, helping to gently refine the skin’s surface without causing dryness or irritation.
A Skincare Routine That Works for Oily Skin
You don’t need a 10-step routine. A few well-chosen products used consistently can make a big difference.
Morning Routine
- Cleanser
- Lightweight lotion or serum
- Oil-free moisturiser
- SPF
Evening Routine
- Cleanser
- Exfoliant (2–3 times a week)
- Barrier-supportive serum or treatment
Look for products that are non-comedogenic, lightweight and designed specifically for skin care for oily skin. Ingredients like niacinamide, zinc and salicylic acid can also be helpful additions to your routine.
