APLB Azelaic Acid Serum — azelaic acid is one of the gentler options for skin dealing with bumps, congestion and the marks left behind after a breakout. APLB pairs it with peptides and centella asiatica at 31.7% of the formula, in a watery ampoule that layers under a moisturiser without pilling.
The texture is thin and fragrance-free, which is usually what reactive skin needs from an active step.
Best for
Blemish-prone and congested skin, uneven texture, and anyone who has found stronger acids too harsh.
How to use APLB Azelaic Acid Serum
Two or three drops on clean skin at night, before your moisturiser. Introduce it every other night for the first two weeks. Sunscreen the next morning is not optional with any acid in the routine.
What is in it
Peptides
Peptides are short chains of amino acids used as signals. The theory is straightforward: certain sequences resemble the fragments skin produces when it repairs itself, so applying them encourages the repair response — more collagen, better firmness. The evidence is real but more modest than the marketing, and it is slow. Peptides are a sensible addition to a routine that already has the basics right, not a substitute for a retinoid or sunscreen. Background reading on peptides if you want the chemistry behind it.
Azelaic acid
Azelaic acid is unusually versatile: it is antibacterial, mildly keratolytic, anti-inflammatory and a tyrosinase inhibitor. In practice that means one ingredient addressing blemishes, the redness around them, and the brown marks they leave behind. It is also one of the very few actives considered safe during pregnancy, which makes it the standard substitute for people who have had to stop using retinoids.
Centella asiatica
Centella asiatica is the plant behind almost every product marketed as “cica”. Its active fractions — madecassoside and asiaticoside among them — are studied for wound healing and calming irritated skin. In a routine, centella is what makes an otherwise demanding formula usable: it takes the edge off acids and retinoids and helps a stressed barrier settle. It is not a treatment for pigmentation or lines; it is the counterweight that lets those treatments continue.
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 Azelaic Acid Peptide Facial Cream and COSRX AHA BHA Clarifying Treatment 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 APLB Azelaic Acid 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.
What size is APLB Azelaic Acid Serum?
This listing is the 40 ml size, priced at ৳1,250. 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.
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 long before I see a difference?
Longer than most marketing suggests. Pigment and firmness respond over eight to twelve weeks of consistent use, not days, and stopping and restarting resets that clock. Hydration and comfort improve much sooner — often within the first week.
