Cos De BAHA 2% Hydroquinone Serum — hydroquinone is among the most effective topical ingredients for hyperpigmentation, and it is also the most tightly regulated. Cos De BAHA’s 2% Hydroquinone Brightening Serum is intended for short, targeted courses on specific dark patches rather than all-over daily use.
Important guidance
Hydroquinone is restricted or prohibited for over-the-counter sale in a number of countries, and its status varies by market. Use it only where it is legally available to you, and ideally under the direction of a dermatologist. It is not intended for continuous long-term use, and it is not recommended during pregnancy.
How to use Cos De BAHA 2% Hydroquinone Serum
Apply a thin layer to the affected area only, at night, for a limited course. Rigorous daily sunscreen is mandatory — sun exposure while using hydroquinone can worsen the pigmentation you are treating.
What is in it
Hydroquinone
Hydroquinone is the most effective topical treatment for dark marks and also the most regulated — it is prescription-only in many countries and restricted in cosmetics in others. It suppresses pigment production directly and works faster than any of the gentler alternatives. It is intended for defined courses rather than indefinite daily use, sun protection alongside it is mandatory, and it is worth speaking to a doctor before starting on the face. Background reading on hydroquinone 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 I’m From Black Rice 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
Hydroquinone is intended for defined courses rather than indefinite use, and it is regulated as a medicine in several countries. Speak to a doctor before starting a course on your face, and use sunscreen daily throughout.
Common questions
Is Cos De BAHA 2% Hydroquinone 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 use this with my other products?
It layers comfortably with the rest of a normal routine. The general rule is thinnest to thickest, and to introduce one new product at a time so you can tell what is working and what is not.
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.
