K Secret Seoul 1988 Eye Cream and Skincare in Bangladesh

Seoul 1988 is the name printed largest on every box in this range, and K Secret is the company behind it. Everything on this shelf belongs to that one line, built around retinal, niacinamide and snail mucin.

The grid above carries what is in stock with the current figure on each item. The wider shelf is Arogga’s Skincare collection.

Seoul 1988 Is the Line, K Secret Is the Brand

The line name does the heavy lifting on the packaging, so it is the half most people remember. K Secret is the smaller type above it.

The brand half gets written several ways: K Secret with a space, K-Secret with a hyphen, and KSecret closed up. The catalogue itself uses two of those — most titles take the space and a couple take the hyphen — and one record spells the line Seaul instead of Seoul.

All of them are this range. If you came in on the line name alone, the products below are the ones you were after.

Retinal and Retinol Differ by One Letter

Two molecules, not two spellings

Retinol and retinal are both vitamin A derivatives, and the difference between the words is an a. They are not the same ingredient, and the skin has to convert each of them before it can use them.

Retinal sits one step closer to the usable form than retinol does, which is the whole reason a brand bothers to print the distinction.

Which products carry which

This range uses both words, on different items, and the titles are the only place the difference is visible. The eye cream and the main serum say retinol; the night cream and the shot say retinal.

Read the word before the figure on any listing you are comparing. It changes what you are buying more than the number does.

The Eye Cream

K Secret Seoul 1988 Eye Cream with Retinol Liposome 4% + Fermented Bean 30ml is the item this line is known for here. It comes as a 30ml jar, where an eye product is usually a few-millilitre tube.

Eye skin is thinner than the skin on the rest of the face and it reacts sooner. A retinoid made for the face is often too much for it, which is why a dedicated version exists at all.

Apply it on the orbital bone rather than right up to the lash line. Product migrates towards the eye overnight on its own, and starting closer only brings watering and stinging forward.

The Strength Ladder, and Where to Start

Three more retinoid items sit on this shelf, and the figures on them run a long way apart:

• K Secret Seoul 1988 Cream with Retinal Liposome 1% + Fermented Rice 50ml — the lowest figure in the set, in the largest jar
• K Secret Seoul 1988 Serum with Retinol Liposome 2% + Black Ginseng 30ml — the middle rung, and the busiest listing in the range
• K Secret Seoul 1988 Advanced Shot: Retinal Liposome 12% + Black Rice 15ml — the top of the ladder, in the smallest bottle on the shelf

Start at the bottom

Skin builds tolerance to a retinoid over weeks, and there is no way to hurry it. Two nights a week for a fortnight, then three, is the usual way up.

Flaking, tightness and a hot feeling after application mean step back a rung or drop a night, not push through.

At night, and not with everything

Retinoids go on at night. Light degrades them, and skin is doing its repair work then anyway.

Keep strong exfoliating acids to different evenings while you are settling in. Anyone who is pregnant, breastfeeding or already using a prescription skin treatment should ask a doctor before starting one of these at all.

What the Percentage on the Label Measures

Nearly every title in this range carries a percentage, and the figures are not on one scale. Each one belongs to the ingredient named immediately before it.

A snail mucin figure in the nineties describes how much of the whole formula that filtrate makes up. A retinal-liposome figure in single or low double digits describes a delivery complex, where the active itself is a fraction of what the number counts.

So a higher number on one product does not make it stronger than a lower number on another. Compare figures only between items naming the same ingredient, and read the full list on the listing for anything else.

Niacinamide and the Yuja Pair

Two items pair niacinamide with yuja, a Korean citrus. They are K-Secret Seoul 1988 Capsule Cream : Niacinamide 5% + Yuja 50ml and K-Secret Seaul 1988 Glow Serum: Niacinamide 15% + Yuja 30ml.

Niacinamide is a form of vitamin B3 used widely in skincare for uneven tone, visible marks and general dullness. It works on patches that have darkened; nothing applied to the surface changes the tone a person was born with.

The two items also differ in format. A capsule cream suspends the active in beads that break when you rub them in; a serum is already dispersed and goes on under the cream.

Both sit on the Serums & Ampoules and Cream & Moisturizer shelves, which is where their cross-brand neighbours are.

Snail Mucin, in an Essence and a Cream

Snail mucin filtrate is one of the recognisable Korean skincare ingredients, used as a humectant — it holds water against the skin rather than acting on it chemically. This line puts it in two formats at almost the same strength.

K Secret Seoul 1988 Essence : Snail Mucin 97% + Rice 100ml is the watery one, patted on after cleansing while the skin is still damp. K Secret Seoul 1988 Cream : Snail Mucin 93% + Rice 100ml is the one that seals it in afterwards.

A humectant on dry skin in dry air pulls moisture out of the skin instead of into it. That is why an essence wants something occlusive over the top rather than being left bare.

Cleansing Oil First, Foam Second

Why two cleansers

Oil and water do not lift the same things. Sunscreen, makeup and the skin’s own sebum come off with an oil; sweat, dust and the oil cleanser itself come off with a foam.

The order matters more than the brand does. Oil onto dry skin, emulsify with wet hands, rinse, then foam.

The pair on this shelf

Both carry the same pine cica and probiotic pairing: K Secret Seoul 1988 Cleansing Oil with Pine Cica 1% + Probiotics 200ml and K Secret Seoul 1988 Cleansing Foam with Pine Cica 1% + Probiotics 150ml.

Morning cleansing can be the foam on its own. The double round is an evening job, and over-washing is one of the quicker ways to make a retinoid harder to tolerate. More of these sit on the Cleansers shelf.

The Sunscreen Belongs With the Rest

K Secret Seoul 1988 Sunscreen SPF 50+ PA++++ with Pine Tree + Ceramide carries both ratings a sunscreen can carry. SPF measures protection against the burning wavelengths; the PA figure measures the ageing ones, and four plus signs is the top of that scale.

A retinoid routine without daily sun protection is working against itself. Retinoids make skin more sun-sensitive while it adjusts, and the marks these products are bought for darken further in sunlight.

Sunscreen is also the one item here with no size in its title, so check the listing for what the tube holds.

Reading a K Secret Listing

These titles pack more into them than most, in a varying order:

• The brand and the line — K Secret or K-Secret, then Seoul 1988, with one record spelling it Seaul
• The format — Serum, Cream, Eye Cream, Capsule Cream, Essence, Cleansing Oil, Cleansing Foam, Sunscreen or Advanced Shot
• The headline ingredient and its figure — introduced by a colon on some records and by the word with on others
• A second ingredient after a plus sign — black ginseng, fermented rice, fermented bean, black rice, yuja, probiotics or ceramide
• The size — on every title except the sunscreen

Two different items are registered simply as Cream, separated only by what follows. Read past the format word before you order either of them.

What Changes the Price

Across this line the figure moves on:

• The active and its concentration — a retinal complex and a humectant filtrate are not costed alike
• Format — an eye product, a shot and a cleanser sit at different points by nature
• Volume — which runs from a 15ml shot to a 200ml cleansing oil
• Whatever promotion the listing is carrying that week

Volume is the trap here, because the smallest bottle on the shelf is the strongest thing on it. Millilitres and strength run in opposite directions across this range, so a per-millilitre comparison between the shot and the cleansing oil tells you nothing useful.

Settle on the active you want first, then open that listing and read the figure there.

About K Secret

K Secret is a South Korean skincare brand, and Seoul 1988 is the line it sells internationally. The line is built around encapsulated actives — retinal and retinol carried in liposomes, niacinamide in capsule form — paired with fermented and botanical ingredients from Korean cosmetic tradition.

Its range covers serums, face creams, an eye cream, an essence, cleansing oil and foam, and sunscreen. Recurring ingredient pairings run through it: black ginseng and black rice with the retinals, yuja with the niacinamide, pine cica with the cleansers, and rice with the snail mucin products.

The brand sells through Korean beauty retailers, pharmacy chains and online marketplaces across Asia, Europe and the Middle East. In Bangladesh it reaches buyers mainly through online skincare retail rather than through physical counters.

Each item is its own entry in the grid above, with its own stock position and figure.

If you are building a routine rather than replacing one product, the neighbouring shelves are Anti-Wrinkle Creams & Serums and Anti-Aging Products.

Check the ingredient word and its figure in the title before confirming. Several of these differ only in the middle of a long name.

Frequently Asked Questions

1. Is Seoul 1988 the same thing as K Secret?

Yes. Seoul 1988 is the line and K Secret is the brand that makes it. The spellings K Secret, K-Secret and KSecret all point at the same range.

2. What is the difference between retinal and retinol here?

They are different vitamin A derivatives, not alternative spellings. Retinal is a step closer to the form skin uses. The titles on this shelf state which one is in each item.

3. Can I use the eye cream and the serum together?

Both are retinoids, so stacking them from day one is how irritation starts. Introduce one, settle into it over a few weeks, then add the other on alternate nights.

4. Does a higher percentage mean a stronger product?

Only against the same ingredient. The figures on these labels measure whatever is named just before them, so a snail mucin number and a retinal number are not comparable.

5. Morning or night?

Retinoids at night, sunscreen every morning. Niacinamide, the essence and the snail mucin cream work at either end of the day.

6. My skin is peeling after a week. What now?

Cut back to two nights a week, keep acids out of the routine for a while, and moisturise over the top. Peeling that keeps going, or skin that is genuinely sore, is worth showing to a dermatologist.

7. রেটিনাল প্রোডাক্ট কখন লাগাব?

রাতে, মুখ ধোয়ার পর। শুরুতে সপ্তাহে দুই রাত, সহ্য হলে ধীরে ধীরে বাড়ান। পরদিন সকালে sunscreen অবশ্যই দেবেন — নইলে কাজটা উল্টো দিকে যায়। গর্ভাবস্থায় বা বুকের দুধ খাওয়ানোর সময় ব্যবহারের আগে ডাক্তারের পরামর্শ নিন।
