Medicube Vita C Mask — a sheet mask is a delivery method rather than a treatment — an occlusive layer holding a concentrated essence against skin for twenty minutes, so more absorbs than from a serum left to dry.
This one carries vitamin C and glutathione, both of which slow pigment production at the enzyme. As a single session it brightens and hydrates; as a habit alongside daily sunscreen it contributes to tone.
Best for
Dullness and uneven tone, once or twice a week.
How to use Medicube Vita C Mask
On clean skin for fifteen to twenty minutes. Remove while still damp and press the remainder in.
What is in it
Glutathione
It is worth being straight about glutathione: it is the most oversold brightening ingredient on the market, and the gap between what is claimed and what is demonstrated is wide. As a topical antioxidant it is fine, and in a well-formulated product alongside niacinamide or vitamin C it contributes. As a whitening treatment, particularly in injectable form, it is a category to avoid. Background reading on glutathione if you want the chemistry behind it.
Vitamin C
Vitamin C does two useful things at once: it interferes with the enzyme that produces pigment, and it neutralises some of the free radical damage that daylight causes. That makes it a morning ingredient — it works with sunscreen rather than replacing it. Pure L-ascorbic acid is the most studied form and also the most temperamental, oxidising when exposed to light and air. A darkening bottle is a real signal, not a cosmetic one.
What to use it with
A mask is worth following with something that holds the hydration in. From the rest of our range, Medicube PDRN Pink Niacinamide Milky Toner and Medicube Zero Pore One Day Cream are sensible companions, and both are stocked with the same cash-on-delivery terms.

Where it fits in your routine
A mask is a supplement to a routine rather than a step in it. Use one on clean skin after toner, once or twice a week, and follow with moisturiser to hold the benefit in. Leaving a sheet mask on until it dries out is counterproductive — as the sheet dries it draws moisture back out of your skin, so remove it while it is still damp.
Before you start
Keep this away from light and heat, and close it properly. Vitamin C oxidises with exposure — if the liquid turns deep yellow or brown, it has lost most of its potency and is worth replacing.
Common questions
Is Medicube Vita C Mask authentic?
Yes. Euros Belle stocks sealed, unopened units sourced through the brand’s own distribution, and we do not sell testers, decants or refilled packaging. Every order is checked before it leaves us, and you are welcome to inspect the seal at the door before paying.
Can I pay cash on delivery?
Cash on delivery is the only payment method we offer — there is nothing to pay in advance and no card details to enter anywhere. You pay the delivery agent when the parcel reaches you. Inside Dhaka delivery is ৳70 and takes one to two days; outside Dhaka it is ৳130 and takes three to four.
Will it suit my skin type?
Most skin types tolerate it, though anyone with reactive or recently over-exfoliated skin should introduce it slowly. If your barrier is currently compromised — stinging, tightness, unusual redness — repair that first with something simple before adding anything active.
Can I order without using the website?
Yes. Some customers prefer to confirm by message first, so every product page carries WhatsApp and Messenger buttons that open a chat with the product and price already filled in. You can also call the hotline on 01795-081385 during business hours. The order is the same either way, and so is the price.
What if it arrives damaged or wrong?
Check the parcel before you pay — that is the practical advantage of cash on delivery. If a seal is broken, a bottle has leaked or the item is not what you ordered, refuse the delivery and tell us, and we will replace it or cancel the order. Cosmetics that have been opened and used cannot be returned for hygiene reasons.
