Polish pharmacy favorite Ziaja Med is one of those quietly reliable brands that veteran skincare lovers swear by yet newcomers might have scrolled past. Affordable, ingredient focused and refreshingly no nonsense, it enjoys a solid reputation for products that work harder than their price tags suggest.
The latest recruit, rather ambitiously called Deeply Regenerating Night Cream, certainly talks a big game. In Ziaja Med’s words it is an antioxidant vitamin C powerhouse meant to ward off the first fine lines for the 25 plus crowd and soften existing wrinkles for anyone over 40, all while brightening pigmentation, exfoliating away dullness and lending tired skin that elusive healthy glow.
To find out how much of that promise survives contact with real life I committed to a full two week trial, massaging it into face, neck and a slightly neglected décolleté every night before bed, resisting the urge to layer any other treatment over it.
For transparency this review is neither sponsored nor compensated in any way. I bought the product with my own money and the impressions that follow are entirely personal. Skincare is deeply individual so results can vary from one complexion to another.
What Is Deeply Regenerating Night Cream?
This is an overnight treatment from Ziaja Med designed to be the final step in an evening routine. Overnight treatments are formulas meant to sit on the skin for several uninterrupted hours while you sleep, giving ingredients a chance to penetrate without the interference of daytime factors like UV exposure or makeup. They tend to be richer than day creams and often include actives that can be less stable in sunlight.
Here the main active is a stable form of vitamin C paired with moisturising lipids, humectants and a mild exfoliating component. The brand positions it as preventive care for anyone in their mid-twenties while also claiming it can soften established wrinkles in more mature skin. The cream also targets uneven tone by gently lifting dull surface cells and supporting antioxidant defence overnight. Applied to face, neck and décolleté it is meant to replace any separate night moisturiser for the duration of use.
Did It Work?
In the name of science I benched my beloved peptide sleeping mask for three whole nights before the test run began (peer reviewed by exactly nobody yet still feeling very scientific). Fourteen days felt like a reasonable window to see whether the promises on the product would translate to the mirror.
I applied a pea-to-chickpea sized scoop every evening after cleansing and serum, pressing it into damp skin on face, neck and chest. The texture is a classic comforting cream—rich enough to feel cocooning yet not so heavy that it leaves a greasy film. It absorbs in roughly a minute, though on warmer nights a faint tackiness lingered until morning.
Days 1-3: hydration was the immediate headline. My skin woke up looking comfortably plump with fewer pillow creases. No tingling or redness, which told me the vitamin C concentration is either gentle or well buffered. The fragrance, a light floral, dissipated quickly and caused no irritation.
Days 4-7: the subtle glow began to show up under bathroom lighting. Makeup went on a bit smoother and I needed less concealer around the nose. However pigmentation spots on my cheekbones looked exactly the same and the faint vertical line between my brows remained unbothered. I also noticed a couple of tiny closed comedones around the jaw—nothing dramatic but worth noting for acne-prone readers.
Days 8-11: by now the hydration plateaued. Skin felt comfortable through the day but not radically different from my usual routine. The promised gentle exfoliation is very gentle indeed; there was no flaking or evening-out of texture that an acid serum usually gives me. On two mornings the cream had pilled when layered under sunscreen, so I started washing my face before reapplying anything instead of merely rinsing with water.
Days 12-14: results more or less stabilized. Fine lines under the eyes looked marginally softer, likely thanks to moisture rather than collagen magic. Pigmentation, firmness and deeper wrinkles showed no measurable change. The antioxidant claim is harder to verify yet I did appreciate going to bed knowing something protective was on duty.
So did it deliver? Partially. Deeply Regenerating Night Cream is a solid hydrator that lends a nice overnight glow and behaves kindly toward sensitive skin but the wrinkle smoothing and spot fading promises overshoot what two weeks—and possibly the formula—can achieve. I will finish the product on nights when I crave simple comfort yet I won’t be replacing my usual heavy hitters with it permanently.
Deeply Regenerating Night Cream’s Main Ingredients Explained
The star here is Ascorbyl Glucoside, a stabilized cousin of vitamin C that converts to pure ascorbic acid once inside the skin. It offers antioxidant protection, helps nudge collagen production and plays nicely with sensitive complexions, though its brightening power is gentler than the pure form so dramatic fading of dark spots takes patience.
Backing it up is Panthenol (provitamin B5), a tried and true soother that pulls water into the epidermis and keeps inflammation on a leash. Sodium Hyaluronate shows up farther down the list yet still earns its keep by binding moisture to give that plump, just-slept eight-hours look even when you did not.
On the firming front we get Methylsilanol Hydroxyproline Aspartate, a mouthful of a peptide-like molecule that supplies hydroxyproline, one of the building blocks of collagen. Claims of wrinkle reduction often lean on this type of ingredient; in practice it helps support skin structure over time but should not be mistaken for in-office results.
The texture owes its cushy finish to a mix of emollients such as Butylene Glycol Dicaprylate/Dicaprate, Isononyl Isononanoate and Ethylhexyl Stearate plus the classic fatty alcohol Cetearyl Alcohol. Dimethicone seals everything in to reduce overnight water loss while keeping the formula from feeling oily.
For light exfoliation the cream relies on Citric Acid at a modest concentration that smooths without visible peeling. It is gentle enough for nightly use yet mild enough that rough patches will likely still need a dedicated acid serum.
Preservation duties fall to Methylparaben and DMDM Hydantoin. The latter is a formaldehyde-releaser which some users prefer to avoid, though it remains permitted in cosmetics at low levels. Fragrance is present too; it smells fresh and brief but could be a deal breaker if you are extremely scent-sensitive.
Are any of these ingredients comedogenic? A few of the richer esters like Ethylhexyl Stearate and Isononyl Isononanoate rate moderate on the comedogenic scale, meaning they can clog pores for skins already prone to breakouts. Comedogenic simply describes substances that tend to block follicles and trigger comedones, the technical term for whiteheads and blackheads.
Good news for vegan or vegetarian readers: the INCI list contains no obvious animal-derived materials, so formulation-wise it appears vegan friendly. As always brand policies on animal testing vary by market so check local regulations if cruelty free status matters to you.
Pregnancy safety is trickier. While vitamin C, hyaluronic acid and panthenol are generally considered low risk during pregnancy the presence of parabens, formaldehyde-releasing preservatives and fragrance means it is best to run the ingredient list by your obstetrician before slathering it on nightly. When in doubt park it on the bathroom shelf until you get a professional green light.
Final housekeeping: there are multiple PEGs and silicones inside, perfectly acceptable for most users yet they can interfere with certain water-free vitamin A treatments if you are a layering enthusiast. Keep that in mind when planning your evening lineup.
What I Liked/Didn’t Like
After two weeks here is the straightforward rundown of how the cream behaved on my skin.
What Works Well:
- Comfortable silky texture that absorbs quickly yet still feels nourishing till morning
- Noticeable overnight hydration that leaves skin plump and helps softening fine lines
- Stable vitamin C and panthenol offer gentle antioxidant support without irritation so it suits reactive complexions
- Vegan friendly formula at a wallet conscious price point
What to Consider:
- Brightening and wrinkle smoothing are subtle so results may underwhelm anyone chasing rapid change
- Can pill when layered under sunscreen the next morning requiring a full cleanse instead of a quick rinse
- Contains fragrance plus a formaldehyde releasing preservative and a few medium level comedogenic emollients which may not suit very sensitive or breakout-prone skin
My Final Thoughts
After two weeks of nightly courtship I can comfortably say Deeply Regenerating Night Cream is the dependable friend who listens more than it dazzles. It locks in moisture, adds a hint of morning glow and politely refrains from triggering drama on sensitive skin. At the same time the lofty promises of erasing wrinkles and spots feel a tad aspirational, at least within the window I tested. That leaves us at a respectful 7/10: solid, pleasant, reasonably priced but not the kind of revelation that elbows long-time staples off my vanity.
Who should invite it home? Anyone in the “my skin feels tight at 10 pm and I am not ready for heavyweight actives” bracket, especially if fragrance is not a deal-breaker and your budget prefers a pharmacy counter to a gold-foiled boutique. Who might pass? Dedicated acid lovers, retinoid regulars or those chasing rapid pigment lift will likely crave more firepower. I would recommend it to a friend who wants uncomplicated comfort yet I would attach a footnote that patience is mandatory.
If you want to cast a wider net, a few other products have earned my nighttime approval. Nocturnal Revive Cream by Deascal is my top all-rounder pick: balanced hydration, a whisper-light finish and a price that never feels extortionate. For a plusher, collagen-coddling experience Pro-Collagen Overnight Matrix by ELEMIS wraps skin in a cashmere-like veil that still lets pores breathe. Those who love a gel-cream that somehow firms while you sleep should meet Bouncy & Firm Sleeping Mask by LANEIGE, a K-beauty classic that lives up to its springy name. Finally Squalane + Ectoin Overnight Rescue by BIOSSANCE steps in when barrier tantrums strike, blending cushiony squalane with ectoin to calm and replenish without heaviness.
Before you slather anything new all over your face, a quick PSA: patch test on a discreet area for a couple of nights first, apologies for sounding like the over-protective parent of your skincare shelf. Remember results hinge on consistent use and will gradually fade if the product is abandoned in favour of the next shiny promise, but you already knew that.
