Deep Vita C Ampoule
Deep Vita C Ampoule
Product Description
MediCube Deep Vita C Ampoule is a high-strength Korean brightening treatment powered by 14.5% pure vitamin C (ascorbic acid), supported by glutathione and soothing bisabolol. Housed in a clever 3-vial, light-shielding system that keeps the notoriously unstable vitamin C fresh, it targets dark spots, post-acne marks, and dullness for a visibly more even, radiant tone โ with a noticeable tone-up the brand says you can see in as little as 7 days.
โจ Texture & Feel
Potent 14.5% Vitamin C
Pure ascorbic acid at 145,000 ppm brightens, fades pigmentation, and helps support collagen.
Light-Shielding Vials
Three opaque, two-tier stability bottles protect the unstable vitamin C from light and oxidation.
Glutathione Glow
Pairs vitamin C with glutathione, a master antioxidant, to amplify the tone-evening effect.
Calming Bisabolol
Chamomile-derived bisabolol helps buffer the acidity so the high dose stays comfortable.
๐ก๏ธ Safety & Compatibility
Topical vitamin C and glutathione are generally low-risk, but the formula contains fragrance and a trace chemical UV filter (octinoxate). Check with your doctor first.
Contains polysorbate 60, sunflower seed oil, and esters that can feed malassezia yeast.
MediCube advises NOT using this at the same time as retinol, AHA, BHA, or niacinamide โ split them between AM and PM.
Hypoallergenic-certified and bisabolol-buffered, though pure vitamin C may sting on first use.
Vitamin C can increase photosensitivity. Daily broad-spectrum SPF is essential while using it.
High-strength actives warrant a 24-hour patch test, especially for reactive or first-time vitamin C users.
๐ฌ Ingredient Breakdown
๐ Ascorbic Acid (Pure Vitamin C) 14.5% Proven
The gold-standard brightening antioxidant. At 145,000 ppm this is a high, treatment-level dose that helps inhibit melanin production, fade dark spots, and support the skin's own collagen.
- Source: L-ascorbic acid is the most-researched topical vitamin C, shown to brighten hyperpigmentation and aid collagen synthesis.
- Source: The effective topical range is generally cited as 8โ20%; this formula sits at the strong end.
๐ Glutathione Booster Promising
A master antioxidant and tyrosinase inhibitor frequently paired with vitamin C for a clearer, more even, "lit-from-within" complexion.
- Source: Studies suggest glutathione can lower melanin and shift skin toward a lighter, brighter pigment.
- Source: It works synergistically with vitamin C, which helps keep glutathione in its active reduced form.
๐ Panthenol (Pro-Vitamin B5) Soothing Proven
A soothing humectant that calms, hydrates, and supports the skin barrier โ useful for buffering the intensity of a strong vitamin C.
- Source: Panthenol is well documented for anti-inflammatory, barrier-supporting, and wound-healing benefits.
๐ง Sodium Hyaluronate Hydration Proven
The salt form of hyaluronic acid; it draws water into the upper layers of skin for a plumper, hydrated, comfortable feel.
- Source: A proven humectant that can hold many times its weight in water for surface-level hydration.
๐พ Beta-Glucan Barrier Promising
A soothing, hydrating polysaccharide that helps calm reactive skin and reinforce a healthy moisture barrier.
- Source: Research links beta-glucan to soothing, moisturizing, and barrier-reinforcing effects on skin.
๐ซ Terminalia Ferdinandiana (Kakadu Plum) Antioxidant Promising
One of the richest natural sources of vitamin C, reinforcing the formula's overall brightening and antioxidant punch.
- Source: Kakadu plum is among the highest known botanical sources of vitamin C, valued for antioxidant support.

๐ Where It Fits in Your Routine
Best used in the morning after toner and before moisturizer. Always finish with SPF โ vitamin C boosts daytime UV defense but also raises sun sensitivity.
๐ How to Use
Cleanse & Tone
Start on clean skin and apply your usual toner so the ampoule absorbs evenly.
Dispense
Use the shared dropper to apply 3โ4 drops across the face, avoiding the eye area and any broken skin.
Pat In
Gently press into skin until absorbed. A mild tingle is normal; if you're new to vitamin C, start every other day.
Seal & Protect
Follow with moisturizer, and never skip broad-spectrum sunscreen in the morning.

โ Frequently Asked Questions
Topical vitamin C and glutathione are generally considered low-risk during pregnancy, and this formula has no retinoids, salicylic acid, or hydroquinone. However, it does contain fragrance and a trace chemical UV filter (ethylhexyl methoxycinnamate / octinoxate) that some people prefer to avoid while pregnant. As with any active, confirm with your OB/GYN or dermatologist before use.
No. The formula contains polysorbate 60, sunflower seed oil, and several esters that can feed malassezia yeast. If you're prone to fungal acne, this is not an ideal pick โ a stripped-back, ester-free vitamin C would be safer.
MediCube specifically recommends NOT using this ampoule in the same routine as retinol (vitamin A), AHA, BHA, or niacinamide. The simplest approach is to use this vitamin C in the morning and save those other actives for the evening to avoid irritation and reduced efficacy.
It shines on oily, combination, and normal skin that wants brightening and dark-spot fading. Dry skin should layer a richer moisturizer on top, while very sensitive or fragrance-averse skin should patch test and introduce it slowly.
MediCube highlights a visible tone-up in about 7 days, with many users reporting brighter, more even skin within 2โ4 weeks. Fading of stubborn dark spots and post-acne marks typically takes around 4โ12 weeks of consistent daily use.
Use it in the morning after cleansing and toner, and before moisturizer. Always finish with sunscreen, since vitamin C increases sun sensitivity while also boosting your daytime antioxidant and UV defense.
It's lightweight and water-based with a low comedogenic profile (roughly 2/5). Most acne-prone users tolerate it well, though it isn't fungal-acne safe because of its oils and esters.
Pure vitamin C oxidizes over time, so aim to finish each opened vial within about 3 months and store it cool and dark โ refrigeration helps. The clever 3-vial system lets you keep the unopened bottles fresh until you need them. If the liquid turns deep yellow or brown, its potency has dropped and it's time to replace it.
Verdict: MediCube's Deep Vita C Ampoule is a genuinely high-strength vitamin C treatment that punches above many pricier rivals. The 14.5% pure ascorbic acid, glutathione pairing, and smart light-shielding vials deliver real brightening and dark-spot fading for most users, while the lightweight, fast-absorbing, hypoallergenic-tested feel makes it an easy daily AM brightener. Just go in informed: it's fragranced, not fungal-acne safe, can sting at first, and is best kept cool to fight oxidation. If you want a potent, results-driven K-beauty vitamin C and don't mind a citrusy scent, it's a strong recommend. (Prices and platform ratings are approximate and vary by retailer and region.)
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.
Just because a product is not free from a common preference does not mean it's a bad product! You can make a personal decision whether or not you want to use a product that contains these ingredients or not - click the labels of the preference to read more about them.
Quick Product Notes
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging ยซpromisesยป it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
Ingredients Related to Skin Types
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
