Cos De BAHA 1% Hyaluronic Serum — Cos De BAHA’s approach across its entire range is to take one active, put it at a meaningful concentration, and leave out almost everything else. The 1% Hyaluronic Acid Serum is the clearest example: hydration, delivered plainly, at a price that makes daily generous use realistic.
Because there is nothing else in it, it layers under or over anything without interaction concerns.
Best for
Dehydrated skin of any type, and as a buffer layer under stronger actives.
How to use Cos De BAHA 1% Hyaluronic Serum
Apply to damp skin — hyaluronic acid pulls water from wherever it can find it, and on dry skin in dry air that can mean pulling it out of your face. Always seal with a moisturiser on top.
What is in it
Hyaluronic acid
Different molecular weights of hyaluronic acid sit at different depths, which is why good formulas use several rather than one. The larger fractions hold water at the surface and smooth immediately; the smaller ones travel further and hydrate less visibly but more usefully. None of it is permanent — hydration is maintenance, not a cure — but skin that is properly hydrated looks plumper and tolerates active ingredients better. Background reading on hyaluronic acid 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 Zinc Niacinamide Facial Cream and Acwell Licorice pH Balancing Cleansing 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
Patch test on a small area behind the ear or along the jaw before the first full application, particularly if your skin reacts easily. Introduce one new product at a time so that if something does not agree with you, you know which one it was.
Common questions
Is Cos De BAHA 1% Hyaluronic 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.
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.
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.
