Put the three ISDIN Hyaluronic Moisture creams side by side and read the fourth ingredient. In the normal-to-dry version it is glycerin. In the sensitive version it is a soothing agent. In this one it is niacinamide, sitting directly behind the glycerin and ahead of everything else, and that single promotion is the whole story of the oily-skin edition. Everything else about the range, the two hyaluronic acid weights, the panthenol and urea, the refill pod, the camellia-and-ferment marketing, is shared. What makes this the cream oily skin should actually buy is that ISDIN put the one ingredient with real evidence for sebum control in a position where it can do something.
The range dates from 2022, when ISDIN finally added a plain daily moisturizer to an Isdinceutics line that had been all serums and sunscreens, and split it three ways by skin type. Four years and a couple of hundred reviews later, the oily version has a specific, consistent fan base: people who had been told for years that oily skin should skip moisturizer, tried this one, and discovered their skin got less shiny rather than more. That experience is the product's argument, and it holds up to the ingredient list.
The formula is built as a mattifier that refuses to dehydrate. Water, dimethicone and glycerin lead, then niacinamide, then silica, the porous mineral that absorbs surface oil and gives the finish its soft powdery matte. A prebiotic sugar, alpha-glucan oligosaccharide, comes seventh, then panthenol and squalane, the only real emollient in the list and the right one for oily skin because it mimics the skin's own lipid without clogging. The middle of the list is the range's shared hydrating cast, trehalose, urea and later two hyaluronic acid weights and serine, with the acrylate polymer network that gives the gel-cream its bounce. Fragrance appears about halfway down, and near the bottom, the same moth bean and lentil seed extracts, Alteromonas ferment and film-forming sugars that ISDIN gives brand names to, plus two dyes. There is no alcohol, no heavy oil and nothing with a comedogenic reputation.
On the face it behaves like a very good primer that happens to moisturize. The texture is a light whipped gel-cream with a faint silky slip; it spreads thin, dries in about a minute to a soft matte and disappears. Skin feels hydrated rather than tight, which is the squalane and humectants at work, and shine stays down until mid-afternoon on most oily faces, which is the silica. Under sunscreen it is excellent as long as it is applied thinly; a thick layer of the silica-acrylate gel can pill when an SPF is rubbed over it, which is the most common practical complaint. Under makeup it gives foundation a grippy, even base.
The longer-term effect is the niacinamide's, and the evidence for that is unusually direct for a moisturizer ingredient. A pair of double-blind, controlled trials using a 2% niacinamide moisturizer found significantly reduced sebum excretion in Japanese subjects after two and four weeks and reduced casual sebum levels in Caucasian subjects after six weeks. Niacinamide at similar levels has separately been shown to improve the appearance of pores and even out tone. ISDIN does not publish the percentage here, but fourth position behind glycerin puts it in the range where those studies were run, and users who stay with the cream for a month or two describe exactly that: less oil by the end of the day, pores that look a little tighter, a calmer, more even surface. That is a real benefit that most mattifying creams, which simply absorb oil and leave the underlying skin unchanged, do not offer.
The drawbacks are the ones the whole range shares. The fragrance is light and pleasant and has no business in a product for skin that is often acne-prone and irritated by treatment; the sensitive version drops it but loses the silica and niacinamide in the process, which is a frustrating trade. Yellow 5 and Blue 1 tint the cream for no benefit. The branded botanicals are trace-level. And $65 for 50 g is a premium for a niacinamide and silica gel-cream, though the refill pod at $55 and a jar that lasts two months at twice-daily use bring the running cost to around $28 a month, which is competitive with clinical-brand mattifiers that offer less.
It is also honest to say what it will not do. It is a moisturizer with a useful active, not an acne treatment; it will not clear breakouts on its own, and it does nothing for blackheads that a salicylic acid would not do better. Combination skin with dry cheeks in winter may find the matte finish a little austere on those areas and want the normal-to-dry version there. And the shine control, good as it is, is a working-day effect that fades by evening, not a permanent change.
For oily and combination skin that has struggled to find a moisturizer worth applying, this is a well-reasoned, comfortable, refillable answer with an active that earns its place. The niacinamide in fourth position is what makes it worth choosing over its siblings and over most mattifying creams; the fragrance and the price are what keep it from being the obvious choice for everyone.
