APLB AHA Serum — AHA works on the surface, BHA gets into oily pores, PHA is the larger, slower molecule. Putting all three at a modest strength — with centella and tea tree alongside — is a common Korean approach to exfoliation that does not strip.
Best for
Blackheads, closed bumps, rough patches and skin that clogs easily.
How to use APLB AHA Serum
Two nights a week to start, on clean dry skin, before moisturiser. Do not stack it with retinol on the same night. Sunscreen the next morning.
What is in it
AHA
AHAs are water-soluble, which is the practical difference between them and BHA. They act across the surface rather than descending into the pore, so their strength is texture, dullness and the general look of skin that has stopped reflecting light. Concentration matters less than frequency: a modest percentage used consistently beats a high percentage used aggressively and then abandoned when skin reacts. Background reading on alpha hydroxy acids if you want the chemistry behind it.
BHA
The reason salicylic acid has outlasted almost every other anti-blemish trend is that it treats the mechanism rather than the symptom. Blocked pores are sebum plus shed cells; BHA loosens both, inside the pore. It pairs badly with a retinoid on the same night for most people, and it pairs very well with niacinamide, which handles the oil production that caused the blockage in the first place.
PHA
Polyhydroxy acids are the gentlest of the exfoliating acids. Their molecules are larger than AHA molecules, so they work more slowly and stay nearer the surface — less exfoliation per use, but far less irritation. They also hold water, so they hydrate while they exfoliate. PHA is the sensible choice for sensitive or reactive skin that cannot tolerate glycolic acid, and it is a common third acid in multi-acid formulas for exactly that balancing reason.
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 Hyaluronic Acid Ceramide HA B5 Facial Cream and Anua 70+ Glow Milky 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
Exfoliating acids increase sun sensitivity, so daily sunscreen matters more than usual while you are using this. Do not layer it with a retinoid on the same night until you know how your skin handles each on its own.
Common questions
Is APLB AHA 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 AHA 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.
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.
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.
