Skincare for Combination Skin — and What Actually Helps the Appearance of Large Pores

Combination skin is the most common skin type, and also the one that generates the most confusion when it comes to choosing products. The challenge is that two different skin conditions are present on the same face at the same time — typically an oilier T-zone alongside drier or more balanced cheeks — and what works well for one area is not always right for the other. Add in concerns about pore appearance, which tend to cluster in the oilier areas, and it is easy to see why the category feels overcomplicated.

The good news is that the ingredient approach for combination skin and pore appearance overlaps considerably — the same actives that help manage oiliness in the T-zone also tend to support a more refined-looking skin surface overall.

Why pores look the way they do

Pores do not open and close. They do not respond to steam or cold water the way many beauty myths suggest. What affects how visible they are is largely a matter of what is in them and how the skin around them looks.

When sebum and dead skin cells accumulate in a pore, it stretches and becomes more visible. Skin that is well-exfoliated, with a smooth surface texture, tends to make pores look smaller — not because the pore itself has changed, but because the surrounding skin looks more even. This is a useful distinction because it shifts the focus from products that claim to "shrink" pores to products that actually do something for the surface and the composition of what is inside them.

The ingredients the research points to

Niacinamide

Niacinamide reached dermatologist consensus for dark spots and redness in the JAAD 2025 Delphi study — a two-round expert review completed by 62 dermatologists across 43 centres — and is widely used in formulas for oily and combination skin because of its association with a more refined-looking surface and a less shiny complexion. For combination skin specifically, it is one of the more versatile actives available: it suits both the oilier and drier areas of the face without over-drying either. It is well-tolerated, pairs easily with other actives, and is found across a wide range of price points.

Retinoids

Retinoids — and specifically cosmetic retinol — reached dermatologist consensus for large pores in the JAAD 2025 study, alongside fine lines, acne-prone skin, dark spots, and oily skin. For pore appearance, retinol is associated with a more even-looking skin texture over time, partly through its effect on skin cell turnover and the look of the surrounding skin surface. It takes longer to see results compared to some other actives, and skin can take a few weeks to adjust to it — starting with a lower concentration and using it in the evening is the standard approach. The prescription forms of retinoids (tretinoin, adapalene in the EU) are a separate matter for a dermatologist; cosmetic retinol is what falls within the scope of skincare.

Salicylic acid

An oil-soluble BHA that can work inside the pore rather than just on the surface, salicylic acid reached dermatologist consensus in the JAAD 2025 study for acne-prone and oily skin. For combination skin, it is most useful in the T-zone and oilier areas — applied as a toner, serum, or targeted cleanser — rather than across the whole face. At cosmetic concentrations it is associated with a clearer-looking, less congested skin surface.

The particular challenge of combination skin

The temptation with combination skin is to treat each zone separately with very different products — a mattifying formula on the T-zone, a richer one on the cheeks. This approach is not wrong, but it tends to make routines more complicated than they need to be. Many well-formulated products for combination skin balance hydration and oiliness in a way that suits both zones, and starting with a single routine before deciding to differentiate by area is usually more useful.

The most common mistake for combination skin is using formulas designed for oily skin across the whole face. These can be too stripping for the drier cheek areas, leading to a cycle where the T-zone continues to look oily while the rest of the face feels tight or looks dull. A gel or lightweight lotion moisturiser with ceramides and niacinamide tends to work across both zones more reliably than a heavily mattifying formula.

A useful routine structure for combination skin

The foundation is the same as for most skin types — cleanse, active, moisturise, protect — but with a few adjustments for the mixed nature of the skin:

• A gentle cleanser that does not over-strip. For combination skin, a gel cleanser or a cream-gel hybrid usually gives a thorough cleanse without leaving the drier areas feeling tight.
• A niacinamide serum, applied across the whole face. This is the workhorse ingredient for combination skin — it suits both zones and addresses the look of pores and oiliness without exacerbating dryness elsewhere.
• A lightweight moisturiser with ceramides, applied across the face. The T-zone may absorb it quickly and produce some oiliness through the day regardless; this is normal and does not mean the moisturiser is wrong.
• SPF in the morning. Sun exposure over time makes pores look more visible, not less, because it affects skin texture and elasticity — so SPF is relevant to pore appearance in a longer-term sense.
• A retinol product in the evening, introduced gradually if pore appearance and texture are primary concerns.

How Dewi approaches combination skin and pores

For a combination skin profile focused on the appearance of pores, Dewi weights the ingredient evidence for this concern — including the JAAD 2025 consensus actives — alongside how well the formula suits combination skin. Fragrance preference, budget, and sensitivity are factored in if set. The scoring is done per product across the full catalogue, so a formula that scores well for oily skin but poorly for a balanced or drier cheek area would reflect that in the overall match.
