Oily Skin: How to Build the Right Routine (UK Guide)

Oily skin overproduces sebum, which leads to shine, visible pores and congestion. The aim of a good routine is to balance oil and keep pores clear without stripping the skin, since harsh products can trigger even more oil. Think gentle, consistent and oil-free.

How do you tell if you have oily skin?

Oily skin has a few recognisable signs, though most people sit somewhere on a spectrum rather than fitting one label perfectly. You may have oily skin if you notice:

• Shine across the T-zone (forehead, nose and chin), often within a few hours of cleansing.
• Visible or enlarged-looking pores, particularly around the nose and cheeks.
• Frequent congestion, blackheads or breakouts as pores become blocked.
• Makeup and SPF that slides or breaks down faster through the day.

If only your T-zone is oily while your cheeks feel normal or dry, you likely have combination skin, and much of this guide will still suit you. It is also worth knowing that skin can look oily but feel tight, which is usually a sign of dehydration rather than a reason to strip it further. When in doubt, treat gently first and adjust.

Which ingredients and actives suit oily skin?

The most helpful actives for oily skin regulate oil, clear pores and hydrate without heaviness. A few well-chosen ingredients matter far more than a long, complicated routine.

• Salicylic acid (BHA): an oil-soluble exfoliant that gets inside the pore to clear the sebum and dead skin that cause blackheads and congestion. It is one of the best-suited actives for oily and blemish-prone skin. Learn more in our salicylic acid glossary entry, and browse our salicylic acid collection.
• Niacinamide: a form of vitamin B3 that helps support a balanced-looking complexion, can help pores appear less prominent and supports the skin barrier. It pairs well with oil control without over-drying. See our niacinamide glossary entry and shop niacinamide skincare.
• Lightweight, oil-free hydration: ingredients like hyaluronic acid and glycerin add water-based moisture in a gel or fluid texture, so skin stays hydrated without feeling greasy. Hydrated skin is less likely to overcompensate with extra oil.
• Gentle exfoliating toners: a well-formulated toner can help keep pores clear between deeper treatments. Explore our toners for oil-balancing options.

Salicylic acid is a BHA, and it behaves quite differently from AHAs like glycolic and lactic acid. If you are deciding which suits you, our guide to AHAs and BHAs breaks down what each does and when to reach for them. For a curated edit built around oil control, our oily skin collection is a good place to start.

What's a simple AM/PM routine for oily skin?

Consistency beats complexity. This straightforward routine covers the essentials and can be built up gradually once your skin is comfortable.

Morning

• Cleanse: a gentle gel or foaming cleanser to remove overnight oil without stripping.
• Treat (optional): a niacinamide serum to help balance oil and support the barrier.
• Hydrate: a lightweight, oil-free gel moisturiser.
• Protect: a broad-spectrum SPF 30 or higher, ideally a non-greasy or mattifying formula. Daily sunscreen is non-negotiable for every skin type.

Evening

• Cleanse: the same gentle cleanser, or a double cleanse if you have worn makeup or SPF.
• Exfoliate: a salicylic acid treatment or toner a few nights a week to keep pores clear. Build up slowly rather than using it every night from the start.
• Hydrate: your oil-free moisturiser to seal in moisture.

Introduce one new active at a time and give your skin a couple of weeks to adjust before adding another. If skin feels tight or looks irritated, scale back the frequency.

What should you avoid with oily skin?

Many oily-skin frustrations come from over-treating rather than under-treating. A few things to steer clear of:

• Harsh or stripping cleansers: products that leave skin squeaky and tight can prompt more oil production, not less.
• Over-exfoliating: using acids or scrubs too often can compromise the barrier, leaving skin sensitised and, ironically, oilier.
• Skipping moisturiser: leaving skin dehydrated often makes oiliness worse. Choose a lighter texture rather than nothing.
• High-alcohol astringents: heavy denatured-alcohol toners can give a short-term matte feel but tend to dehydrate over time.
• Heavy, occlusive creams: rich balms and thick creams can feel greasy and may contribute to congestion; look for non-comedogenic, oil-free options instead.

Frequently Asked Questions

What is the best routine for oily skin?

A simple routine of a gentle cleanser, an oil-free hydrator and daily SPF, with salicylic acid used a few times a week, suits most oily skin. Niacinamide is a helpful optional step to support oil balance. The key principle is to keep pores clear without stripping the skin.

Should oily skin use moisturiser?

Yes. Skipping moisturiser can leave skin dehydrated, which may prompt it to produce even more oil. Choose a lightweight, oil-free gel or fluid rather than a rich cream, so your skin stays hydrated without feeling greasy.

Is salicylic acid good for oily skin?

Salicylic acid is one of the best-suited actives for oily and congestion-prone skin because it is oil-soluble and works inside the pore to clear blockages. Start a few nights a week and build up gradually to avoid over-exfoliating.

Does oily skin need SPF?

Absolutely. Every skin type needs daily broad-spectrum SPF 30 or higher. For oily skin, look for lightweight, non-greasy or mattifying formulas so protection does not add shine or feel heavy through the day.

Can drinking water reduce oily skin?

Staying hydrated supports overall skin health, but oil production is mainly driven by genetics and hormones rather than water intake alone. A consistent topical routine with oil-free hydration and gentle exfoliation makes far more difference to how oily your skin looks.
