Enlarged pores do not literally disappear because of a single cosmetic product. However, the right serum can help skin look smoother, reduce excess sebum and minimise the appearance of blocked pores. The main differences lie in the formula, the instructions for use and how well the product suits your skin.
Pores do not open and close like a door. Claims that a product will permanently reduce pore size should therefore be interpreted with caution. Instead, look for verifiable information, such as the presence of PHA, AHA, BHA, niacinamide or azelaic acid, and consider the serum’s purpose: exfoliating, hydrating or helping to regulate sebum.
A serum for blocked pores may contain acids. If you combine several exfoliating products, retinol and a strong niacinamide serum without building up gradually, your skin may feel dry or irritated. A tingling sensation does not automatically mean that a formula works better.
A lightweight texture is pleasant, but it does not tell you everything about whether a product is suitable. Also check the ingredients list, recommended use and warnings. Some formulas contain fragrance, alcohol, essential oils or multiple acids. This can be relevant if you have sensitive or easily reactive skin.
Several ingredients may be relevant in a serum for blackheads and visible pores:
An AHA BHA PHA serum contains several exfoliating acids. This can be practical if you are looking for one product, but makes it even more important to introduce it gradually.
For oily or combination skin, a watery, fast-absorbing formula may feel more comfortable than a heavy, oily serum. A hydrating serum containing glycerine, panthenol or hyaluronic acid can help keep your routine comfortable.
If you have sensitive skin, look for descriptions such as fragrance-free, alcohol-free and warnings not to use the product on damaged or inflamed skin. “Hypoallergenic” or “dermatologically tested” does not guarantee that everyone will tolerate the product without problems. According to the brand’s product information, individual reactions may still occur.
Check how many pumps or drops are needed and how often the serum may be used. A product that should be applied daily requires a different routine from an exfoliating serum that is best introduced gradually.
Store the bottle according to the label, usually in a cool place away from direct sunlight. Check the packaging for the expiry date, batch code and period after opening. Do not use a serum on damaged skin and stop using it if you experience persistent redness, itching or a burning sensation.
Why it suits this profile: Among other ingredients, this lightweight ampoule contains glycerine, panthenol, hyaluronic acid and Centella Asiatica. This makes it suitable as a simple hydrating step for combination or sensitive skin.
The product information describes a non-sticky texture and a formula without strong exfoliating acids, helping you keep your routine straightforward.
30 ml; watery texture; Centella Asiatica, panthenol and several forms of hyaluronic acid according to the ingredients list.
Why it suits this profile: If you are specifically looking for an exfoliating facial serum, this product offers a clearly identified PHA formula. According to the product description, the serum contains 7% PHA and is intended for all skin types, including sensitive skin.
The PHA percentage is stated explicitly in the product information. This allows you to compare a specific detail rather than relying solely on a general claim about refined pores.
7% gluconolactone; fragrance-free and alcohol-free according to the product details; panthenol and sodium hyaluronate are included in the ingredients list.
Why it suits this profile: This product combines niacinamide, panthenol, gluconolactone and betaine salicylate with hydrolysed sponge. According to the product information, you may experience a tingling sensation, so it is important to build up use gradually.
The warning about tingling makes it clear that this is not a neutral hydrating serum. Do not use it at the same time as other strong exfoliants or retinol.
30 ml; a combination of niacinamide, panthenol and three types of acid; suitable for evening use according to the product information.
Why it suits this profile: According to the product description, this ampoule has a lightweight, non-greasy texture and is designed to hydrate combination or oily skin. This makes it suitable for daily use without adding several active acids.
The formula is not primarily a powerful exfoliating serum. This reduces the chance of layering several acids without planning.
100 ml; Centella Asiatica, glycerine, panthenol and hyaluronic acid; vegan and cruelty-free according to the product details.

A serum can temporarily make your skin look smoother or less shiny, but visible changes vary from person to person. According to a brand’s own research, certain results may become visible after a week or longer; this is a brand claim and not a guarantee for every user. Give the product time and follow the instructions for use.
Look for a lightweight formula containing ingredients such as niacinamide, PHA or a carefully introduced combination of acids. For sensitive skin, a fragrance-free PHA formula or a hydrating Centella ampoule may be a more logical choice than a product containing several exfoliants, alcohol and essential oils.
Follow the expiry date and period-after-opening information on the packaging. Close the bottle securely and store it away from direct sunlight. Has the scent, colour, texture or your skin’s reaction changed? Stop using the product and check the product information.
