Numbuzin No.5 Goodbye Serum — goodbye Blemish addresses both halves of a breakout problem — the spots themselves and the discolouration that outlasts them by months.
At 50 ml this is a larger bottle than most treatment serums, which suits a product meant for consistent use across the whole face rather than dabbing on individual spots.
Best for
Recurring breakouts with post-inflammatory marks, on skin that does not need a full prescription routine.
How to use Numbuzin No.5 Goodbye Serum
Apply to clean skin before moisturiser, once or twice daily. Use across affected areas rather than spot-treating — most of the value is in preventing the next breakout.
What is in it
The formula here is built around hydration and barrier support rather than a single headline active, which is why it layers easily with the rest of a routine and rarely causes a reaction. Products in this category earn their place by being reliable every day rather than dramatic once. Background reading on skin care 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 Numbuzin No.5 Goodbye 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 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.
How long before I see a difference?
Hydration and comfort usually change within a few days. Anything structural — tone, texture, firmness — takes eight to twelve weeks of consistent use. Judging a product before a full month is generally judging the wrong thing.
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.
