Medicube Deep Vita C Capsule Cream review: buy it as a moisturizer, not a vitamin C serum
Updated October 22, 2026
Buy the Medicube Deep Vita C Capsule Cream if you want your moisturizer to handle the brightening step too: it pairs a stated 5% niacinamide with six vitamin C forms in a capsule-and-gel texture you mix yourself, at $22.99 for 55 g. If you already have a moisturizer you like, the Deep Vita C Capsule Serum is the better buy, and the pads only make sense if you also want a toner step with mild exfoliating acids.
None of the Deep Vita C products is a high-strength vitamin C product. Medicube doesn't publish a vitamin C percentage for any of them, and in each formula the vitamin C forms sit behind niacinamide and sea buckthorn on the ingredient list. Think of the line as niacinamide-led daily care with vitamin C in a supporting role.
This is a researched comparison of current Medicube US product information and Sleepy Hello's product pages, checked October 2026. We haven't worn or tested these products; texture descriptions are Medicube's, and the buying advice comes from comparing formulas, directions, sizes and prices.
What you're buying with the Capsule Cream
Medicube Deep Vita C Capsule Cream, 55 g is a face moisturizer in a jar with two visible parts: golden cream capsules suspended in a clear gel. You scoop and blend them on your fingers. Medicube says more gel gives a lighter feel and more capsule cream gives more hydration, so one jar can sit anywhere between a gel-cream and a richer cream.
It costs $22.99 for 55 g (1.94 oz) at Sleepy Hello, checked October 2026, which works out to about $0.42 per gram.
The stated actives are 50% sea buckthorn (listed as Hippophae Rhamnoides Water, which Medicube calls vitamin tree water) and 5% niacinamide; our product page places both in the capsule portion. Niacinamide is a form of vitamin B3 and, by quantity, the main tone-focused ingredient in this formula. The first ten ingredients on Medicube's US product page are:
Hippophae Rhamnoides Water: sea buckthorn fruit water, the base of the formula
Glycerin: a humectant that draws water into the skin's surface
Water
Niacinamide: vitamin B3, listed fourth
Methylpropanediol, Propanediol, 1,2-Hexanediol, Butylene Glycol and Dipropylene Glycol: light solvents and humectants
Caprylic/Capric Triglyceride: a light emollient
Further down you'll find cetearyl alcohol (a fatty alcohol that thickens the cream, not a drying alcohol), sunflower and soybean oils, gluconolactone (a mild polyhydroxy acid) at position 31, alpha-arbutin, ferulic acid, tocopherol (vitamin E), adenosine and sodium hyaluronate. The full list runs to 61 ingredients.
Two label details are worth knowing before you buy. The ingredient list includes fragrance, at position 24, even though the brand page also lists fragrances under "formulated without", so go by the ingredient list if you avoid added scent. And there's no retinoid in the cream; Medicube lists retinol and retinyl palmitate among the ingredients it leaves out. Medicube positions the cream for combination, dry, oily and sensitive skin.
What vitamin C is in Medicube Deep Vita C Capsule Cream?
The cream lists six vitamin C forms: sodium ascorbyl phosphate, ascorbyl glucoside, 3-O-ethyl ascorbic acid, ascorbic acid, ascorbyl propyl hyaluronate and ascorbyl palmitate. Medicube doesn't publish a percentage for any of them.
Ascorbic acid is pure vitamin C, the form with the most research behind it and also the least stable once it meets water and air. The other five are derivatives: the vitamin C molecule bound to something else (a phosphate, a sugar, an ethyl group, a fatty acid or a hyaluronic acid fragment) so it holds up better in a jar. The trade-off usually discussed is that derivatives act less directly than pure ascorbic acid. According to our product page, the capsules hold liposome-encapsulated vitamin C intended to stay fresh until you mix it with the gel, and the gel carries ferulic acid, an antioxidant often paired with vitamin C for stability.
Where these forms sit on the list matters more than how many there are. The first vitamin C form appears at position 39 of 61 and the last at 54, all after the fragrance at 24. Ingredient order doesn't give exact concentrations, but anything listed after fragrance is usually present in small amounts. That's the main reason this cream behaves differently from a vitamin C serum sold on strength: those usually print a percentage on the box and put ascorbic acid near the top of the list. Here, vitamin C is one ingredient group among many in a niacinamide moisturizer. Alpha-arbutin, another ingredient used for the look of dark spots, appears at position 37, also without a published percentage.
Medicube Deep Vita C cream vs serum: which should you buy?
Buy the cream if you want one product to cover moisturizer and brightening; buy the serum if your current moisturizer already works and you want to add a step underneath it. The two are closer in formula than their names suggest, so most people don't need both.
Medicube Deep Vita C Capsule Serum, 30 ml costs $20.99 at Sleepy Hello, checked October 2026, or about $0.70 per ml. Its label states 77% Hippophae Rhamnoides Water and 5% niacinamide, so it carries more sea buckthorn than the cream's stated 50% and the same niacinamide. It also lists six vitamin C forms, four shared with the cream (ascorbic acid, 3-O-ethyl ascorbic acid, ascorbyl glucoside and sodium ascorbyl phosphate) plus magnesium ascorbyl phosphate and ascorbyl tetraisopalmitate. As in the cream, they sit in the second half of the list with no published percentage.
The supporting ingredients differ. The serum adds glutathione and two hyaluronic acid forms the cream doesn't list (hydrolyzed hyaluronic acid and sodium acetylated hyaluronate). The cream adds alpha-arbutin, ferulic acid and cetearyl alcohol, the fatty alcohol that thickens it. Both formulas list gluconolactone, and both contain sunflower and soybean oils. The serum's list has no "fragrance" entry but does include several aromatic plant oils, among them citron peel, rosemary, litsea cubeba, fennel, coriander and mint oils. Medicube describes the serum as lightweight and fast-absorbing, with visible capsules designed to melt as you massage it in, and says it's designed for daily use; if you're new to vitamin C, the brand suggests building up gradually.
Here's how we'd decide:
Pick the cream if you want fewer steps, like being able to make the texture lighter or richer, or are replacing a moisturizer that's running out anyway.
Pick the serum if you want vitamin C under the moisturizer and sunscreen you already use, or prefer the lightest texture in the line for oily skin.
Use both only if you enjoy the ritual. The overlap is large, and doubling up mostly adds more of the same 5% niacinamide.
How do you use the Medicube Deep Vita C pads?
Use one pad after cleansing: sweep the embossed side from the center of your face outward with light pressure, flip to the silky side for a final pass, then pat in the leftover essence before serum and moisturizer. Don't rinse, keep the pad away from your eyes, and close the jar straight away so the rest stay soaked.
Medicube Deep Vita C Pad, 70 pads is a 150 g jar at $20.99, checked October 2026, about $0.30 per pad. Medicube also suggests resting a pad on one area for 5 to 10 minutes as a mini mask, removing it before it dries. Finish with sunscreen in the morning.
The pad is a toner step, not a replacement for the cream. Its 48-ingredient list starts with sea buckthorn water, water and humectants, then niacinamide at position 5, gluconolactone at 10 and 3-O-ethyl ascorbic acid, its only vitamin C form, at 11. That derivative sits much higher on the pad's list than any vitamin C form does in the cream. The pad also contains lactic acid, an alpha hydroxy acid that loosens dead surface cells, at position 30; Medicube doesn't publish its percentage.
Medicube doesn't give a daily limit, but the product page suggests introducing the pads gradually if your routine is new to leave-on acids. The list also includes palmarosa, citronella and litsea cubeba oils plus geraniol, citronellol and linalool, which are fragrance components, so try a pad on a small area first if scented products tend to bother your skin. A sensible start is every other day, moving to daily if your skin stays comfortable.
The fourth product in the line, Medicube Deep Vita C Daily Quick Mask, 30 sheets, is $22.99, checked October 2026, about $0.77 per sheet. Medicube states 2% niacinamide alongside acetyl glucosamine and ascorbic acid, and directs you to leave a sheet on for about 10 minutes after toner, then pat in the remaining essence. Buy it only if you like a quick sheet mask before makeup.
Can you use Medicube Deep Vita C with retinol?
Yes, with a sensible split. Medicube doesn't publish a rule about combining the Deep Vita C line with retinol, and the Capsule Cream contains no retinoid, so it works as the moisturizer on top of a retinol night. The simple plan is vitamin C serum or pad in the morning, retinol at night, and the Capsule Cream as your moisturizer for both.
If you want to stay within the brand, Medicube Deep Vita A Retinol Serum, 30 ml costs $19.99, checked October 2026. Medicube directs it for evenings: every other evening for the first two weeks, starting with rice-grain amounts on chosen areas, then a thin full-face layer each evening, followed by a gentle moisturizer. The Capsule Cream fits that last step.
Two cautions. First, the Deep Vita C pads contain lactic acid and gluconolactone, so while you're starting retinol, skip the pad on retinol nights rather than stacking acids and retinoids. The Capsule Cream also lists gluconolactone, but at position 31, after the fragrance, so it's still the gentler moisturizer for those nights. Second, the Daily Quick Mask lists retinol near the end of its ingredient list, followed by BHT and BHA. The BHA there is butylated hydroxyanisole, an antioxidant that keeps the formula stable, not the exfoliating acid. The amount of retinol isn't published, but if you're avoiding retinoids for any reason, it's worth knowing the mask contains one and the cream doesn't.
Where the cream fits, and where to buy
In a simple routine, the Capsule Cream goes last at night and just before sunscreen in the morning: cleanse, toner or pad, serum if you use one, then the cream. Medicube's directions say to apply it to face and neck after serum, morning and evening, as the last skincare step.
Our shortlist, with Sleepy Hello prices checked October 2026:
Skip the line if you avoid fragrance and aromatic plant oils entirely; the cream, serum and pads each list one or the other. Skip it too if you want a vitamin C percentage you can compare across brands.
Quick answers
Can you use Medicube Deep Vita C cream in the morning?
Yes. Medicube directs it for morning and evening use on face and neck, and the morning routine should finish with sunscreen on top. Give the cream a minute to settle first so the sunscreen spreads evenly.
Is the Capsule Cream good for oily skin?
Medicube lists oily skin among its intended types, and the adjustable texture helps: scoop more gel and less capsule for a lighter layer. If even that feels heavy, the serum under a gel moisturizer you already like is the lighter route.
Does Medicube Deep Vita C Capsule Cream have fragrance?
Yes. The ingredient list includes fragrance at position 24 of 61, despite the "formulated without fragrances" line on the brand page.
Will it fade dark spots?
Not on its own, and Medicube doesn't present it as a dark spot remover. The brand describes the cream as supporting visible radiance and a more even-looking tone. With vitamin C low on the list and no percentage published, we'd see it as a supporting moisturizer in a brightening routine, and any such routine depends on daily sunscreen.
How long does a 55 g jar last?
Medicube doesn't publish a usage estimate, and it depends on how much you scoop. We wouldn't promise a number of weeks; twice-daily use, as directed, empties a jar faster than using it only at night.
Torriden Dive-In Soothing Cream is the lighter gel for oily and combination skin; the Dive-In Cream adds oils for drier skin. Formulas, use and prices.
