K-Secret Seoul 1988 Cream — liposomal delivery encapsulates the retinal, releasing it more gradually than a straight formulation. That generally means better tolerance at a given strength, which matters with retinal — it is more potent than retinol and correspondingly more irritating.
Fermented rice provides the hydrating, brightening counterweight in the base.
Best for
Fine lines, texture and tone, on skin ready for a retinoid but wary of the adjustment period.
How to use K-Secret Seoul 1988 Cream
Night only. Start twice a week on clean dry skin and build up as tolerated. Expect some dryness initially. Daily sunscreen is required throughout.
Do not use
While pregnant or breastfeeding.
What is in it
Retinal
Retinal is the middle ground many people are actually looking for. Retinol is gentle but slow; prescription tretinoin is fast but punishing. Retinaldehyde converts in a single step, so it acts more quickly than retinol while staying within what normal skin can handle. It is worth choosing when you have used retinol for months and want more, rather than as a first retinoid. Background reading on retinaldehyde if you want the chemistry behind it.
Rice extract
Fermentation is the interesting part of a rice formula. The process breaks larger molecules into smaller ones and generates amino acids and organic acids that were not there before, which is why fermented rice filtrate behaves differently from plain rice water. It hydrates, softens and adds a diffuse glow, and it is about as unlikely to irritate as a skincare ingredient gets.
Retinol
Retinol is the best-evidenced ingredient in cosmetic skincare for fine lines and texture. Skin converts it in two steps into retinoic acid, which speeds cell turnover and prompts collagen production. That conversion is why it works more slowly than a prescription retinoid and why it is far better tolerated. Expect twelve weeks before firmness and line changes are honest rather than imagined, and expect a flaky, tight fortnight on the way there.
What to use it with
A moisturiser works best over something it can lock in, so it belongs after a serum rather than instead of one. From the rest of our range, APLB Liposome Retinol LX Serum and COSRX Salicylic Acid Daily Gentle Cleanser are sensible companions, and both are stocked with the same cash-on-delivery terms.

Where it fits in your routine
A moisturiser is the last skincare step at night and the second-to-last in the morning, with sunscreen going over it. Its job is partly to hydrate and mostly to seal — it locks down the water and the actives applied beneath it, which is why even oily skin does better with one than without. Apply it to slightly damp skin and you will need noticeably less product.
Before you start
This is a night product. Start twice a week, build up slowly, and stop increasing the moment skin starts to feel tight rather than dry. Sunscreen the following morning is not optional. Do not use retinoids while pregnant or breastfeeding.
Common questions
Is K-Secret Seoul 1988 Cream 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 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.
Does the Dhaka climate affect it?
Heat and humidity shorten the working life of most cosmetic formulas, and actives like vitamin C and retinoids are the first to suffer. Keep the product capped, out of direct sun, and away from the hottest corner of a bathroom. A cool cupboard is better than a windowsill, and better than a fridge for most textures.
