Serum for spots and enlarged pores: how to choose a formula that suits your skin

Spots, visible pores and a shiny T-zone don't automatically call for the most concentrated product. A serum for spots and enlarged pores needs to suit your skin type, your existing routine and the ingredients you're already using. For oily skin, the focus is often on sebum and clogged pores. For sensitive skin, redness, dehydration and a damaged skin barrier are at least as important.

Three pitfalls when buying an acne serum

1. A high percentage isn't always the right place to start

Niacinamide, acids and azelaic acid are often presented with high percentages. That only tells you about the concentration, not how your skin will react. A niacinamide serum with 10% or 15% can be interesting for oily or combination skin, but building up gradually is still wise. The same goes for an azelaic acid serum.

2. "Minimising pores" usually means: making them less visible

Pores don't disappear with a serum. Product descriptions typically refer to a smoother skin texture, less sebum or fewer blockages, which can temporarily make pores appear less noticeable. So check whether the formula contains ingredients that match your goal, rather than just relying on the front of the packaging.

3. Too many active ingredients at once

Combining a serum for blemishes with an exfoliant, retinol and a strong acid can unsettle your skin. A serum for acne-prone skin in particular should be introduced gradually. Don't use several new products at the same time. That way, you can better see which product suits you and you limit the risk of irritation.

What to look for in a serum for blemishes

1. Check the active ingredients and concentrations

Always look at the INCI list and product information. Commonly used options include:

  • Niacinamide: often chosen for oily skin, visible pores and uneven skin texture.
  • Azelaic acid: suitable if you want to address not only blemishes but also visible redness or post-acne marks in your routine.
  • Tea tree: a frequently used ingredient in a tea tree serum for troubled skin. Essential oils can cause sensitivity in some people.
  • Centella asiatica: commonly found in a centella serum and used in soothing, hydrating formulas.
  • AHA, BHA and PHA: acids that target skin texture and pores. Build up use slowly and wear sun protection during the day.

Brands may make claims about sebum, redness or spots. Don't treat these as guaranteed results. According to the brand's product description, for example, Medicube Zero Pore One Day Serum contains 15.2% AHA+BHA+PHA and niacinamide. With Some By Mi, the product information states a combination of AHA, BHA, PHA, tea tree and centella is used. Individual skin reactions can vary.

2. Choose a texture you can use daily

A watery ampoule or lotion usually absorbs quickly and feels comfortable under sunscreen or make-up. That can be practical with a serum for oily skin. A formula with hydrating ingredients like glycerine, panthenol or hyaluronic acid may be a better fit when active ingredients quickly cause tightness.

Also pay attention to the size. A 9 ml pack is suitable for gently trying out a formula. A 50 or 100 ml bottle is more worthwhile when you already know the product and use it regularly.

3. Check warnings, shelf life and origin information

Cosmetics sold in the European Union must include mandatory information about ingredients, the responsible person and usage warnings. Check the packaging for the INCI list, expiry date or period-after-opening symbol, and storage instructions.

Test a new serum on a small area of skin first. Stop if you experience persistent redness, swelling, itching or a burning sensation. Don't use an exfoliating serum on damaged skin and combine active formulas carefully. For severe or recurring acne, advice from a GP or dermatologist is wiser than simply adding more serums.

Frequently asked questions

Which serum suits oily skin and enlarged pores?

Look for a lightweight formula with niacinamide, centella or a carefully introduced exfoliant. A pore-refining serum can help reduce the appearance of pores by targeting sebum and skin texture. Don't automatically go for the highest concentration.

How often should you use a serum for spots?

Follow the packaging and, with active ingredients, start on alternate days or a few times a week. A hydrating centella serum can often fit more easily into a daily routine, whereas a serum with AHA, BHA, PHA or 10% azelaic acid may require more gradual adjustment.

How long does a serum last?

Check the expiry date and the period-after-opening symbol on the packaging. Store the bottle closed, in a cool place and out of direct sunlight. A change in smell, colour or texture is a reason not to continue using the product.
