A serum for blemishes and large pores sounds straightforward, but the differences between formulas are significant. Oily skin often benefits from a lightweight texture and ingredients that help reduce visible shine. Sensitive or acne-prone skin, on the other hand, calls for a gentle approach, plenty of hydration and careful consideration of potential irritation.
Marketing doesn't always make the choice any clearer. So don't just look at words like "pore minimising" or "clarifying" – focus on the ingredients list, usage instructions and suitability for your skin type.
A niacinamide serum with 10% sounds appealing, but a concentrated formula can cause stinging or redness for some users. The same goes for an azelaic acid serum or an exfoliating serum with AHA, BHA and PHA.
Start with active ingredients at a low frequency of use. That way, you can see how your skin reacts before using the product daily.
A pore-refining serum can make pores look less noticeable, either temporarily or gradually, by hydrating the skin, limiting shine or smoothing the texture. Pores cannot be permanently "closed". So be wary of product claims that suggest a lasting change.
A face serum for oily skin doesn't have to be drying. When your skin feels tight, make-up can sit less smoothly and dry patches can become more visible. Look for a combination of sebum-regulating ingredients and hydrating agents, such as glycerine, panthenol, hyaluronic acid or sodium hyaluronate.
Niacinamide is commonly used in a serum for spots, a serum for an even skin tone and products for oily or combination skin. The Ordinary Niacinamide 10% + Zinc 1% contains, according to the product information, 10% niacinamide and a zinc salt designed to help balance visible aspects of sebum activity.
Always check the full packaging though. The product information states that this formula may be better applied at a different time of day if you are using certain vitamin C formulas.
An azelaic acid serum can be a good option if you want to tackle not only blemishes but also visible redness or leftover marks. The SKIN1004 Madagascar Centella Azelaic Acid 10 Ampoule contains, according to the label, 10% azelaic acid and centella extract. The manufacturer advises building up gradually and using sun protection during the day.
A slight tingling sensation may occur with the first few applications, according to the product information. Do not use the product on damaged, irritated or sunburnt skin, and stop if irritation persists.
A formula with AHA, BHA and PHA can be appealing for rough skin texture and clogged pores. Medicube Zero Pore One Day Serum lists a combination of 15.2% AHA+BHA+PHA and niacinamide. Some By Mi AHA.BHA.PHA 30 Days Miracle Serum also contains multiple acids as well as fragrance-like components and essential oils according to the ingredients list.
Don't automatically use such formulas alongside other strong exfoliants. Test on a small area first and use sun protection during the day. A serum for acne-prone skin is a cosmetic skincare product and does not replace medical advice.

We've put together a full, up-to-date list of products that fully meet these strict selection criteria and comply with current European safety regulations.
This varies depending on the formula, skin type and frequency of use. Give a new product a few weeks to assess your skin's appearance, unless irritation occurs. Stop if you experience persistent redness, itching or a burning sensation.
It can be done within some routines, but it's wiser to introduce new active ingredients separately. Start by using them every other day and stick with a simple moisturiser. Always check the specific usage instructions and ingredients list.
Look for the symbol showing, for example, 6M or 12M, and check the expiry date on the packaging. Store the serum in a cool, dry place, close the bottle properly and don't leave it in direct sunlight for long periods.
