Medicube Vita Retinol Serum — vitamin A is retinol, and retinol remains the ingredient with the strongest evidence behind it for fine lines, texture and tone without a prescription. Skin converts it in two steps to retinoic acid, which is why it works more slowly and far more tolerably than a prescription retinoid.
Twelve weeks is the honest timeline for an assessment, and the first fortnight is usually dry and flaky.
Best for
Fine lines, uneven texture and early loss of firmness.
How to use Medicube Vita Retinol Serum
At night only, on dry skin, twice weekly to start.
Do not use
While pregnant or breastfeeding. Sunscreen every morning without exception.
What is in it
Retinol
Retinol is the best-evidenced ingredient in cosmetic skincare for fine lines and texture. Skin converts it in two steps into retinoic acid, which speeds cell turnover and prompts collagen production. That conversion is why it works more slowly than a prescription retinoid and why it is far better tolerated. Expect twelve weeks before firmness and line changes are honest rather than imagined, and expect a flaky, tight fortnight on the way there. Background reading on retinol if you want the chemistry behind it.
What to use it with
Seal this in with a moisturiser and apply it to skin that is still damp from a toner — both steps make a measurable difference to how much of the serum stays where you put it. From the rest of our range, APLB Tranexamic Acid Niacinamide Facial Cream and Anua Peach 77 Niacin Essence Toner are sensible companions, and both are stocked with the same cash-on-delivery terms.

Where it fits in your routine
A serum goes on after cleansing and toning, while skin is still slightly damp, and before anything heavier. That order matters more than people expect — the thinnest, most concentrated layer needs direct contact with skin, not a film of moisturiser in the way. Give it thirty seconds to absorb, then seal it in with a cream. If you are using more than one serum, the lighter one goes first.
Before you start
This is a night product. Start twice a week, build up slowly, and stop increasing the moment skin starts to feel tight rather than dry. Sunscreen the following morning is not optional. Do not use retinoids while pregnant or breastfeeding.
Common questions
Is Medicube Vita Retinol Serum 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.
How fresh is the stock?
We buy in small, frequent batches rather than holding large quantities, so what reaches you is well within date. Batch and expiry markings are printed on the packaging and we do not remove or cover them. If anything you receive is close to expiry, tell us and we will replace it.
Does the Dhaka climate affect it?
Heat and humidity shorten the working life of most cosmetic formulas, and actives like vitamin C and retinoids are the first to suffer. Keep the product capped, out of direct sun, and away from the hottest corner of a bathroom. A cool cupboard is better than a windowsill, and better than a fridge for most textures.
How should I store it?
Somewhere cool and out of direct sunlight, with the cap closed properly. Bangladesh’s heat and humidity shorten the life of most formulas, and a bathroom shelf directly above a hot shower is the worst place in the house for anything active.
What size is Medicube Vita Retinol Serum?
This listing is the 30 ml size, priced at ৳2,300. Where a product is available in more than one size, each is listed separately so the price you see is the price for the size shown.
