WHY YOU NEED IT

Choose it when texture, tone and firmness need the same focused routine

Fine lines often look more obvious when the skin is dry or rough, while uneven pigment can make the complexion look less clear. This concentrated night serum combines a retinal delivery complex with brightening and moisture-supporting ingredients, so you can address several visible signs of skin ageing without stacking multiple treatment serums.

FOUR REASONS TO CHOOSE IT

One retinal serum, four practical advantages

Retinal Liposome 2% complex

Encapsulated retinal targets the look of fine lines, rough texture and reduced elasticity while the liposome format improves stability and delivery.

58% black ginseng extract

Panax ginseng root extract is first on the ingredient list, delivering antioxidant care that complements a firming and smoothing routine.

Brightening support built in

Niacinamide and 3-O-ethyl ascorbic acid improve the look of dull areas, visible discoloration and uneven tone.

Moisture and comfort

Glycerin, betaine, macadamia oil and sunflower seed oil replenish moisture and soften the feel of dry skin.

HOW IT WORKS

Liposomal delivery keeps retinal stable and spreads it through the formula

The retinal is enclosed in tiny lipid structures called liposomes. This protects the active, improves its stability and supports efficient, even delivery across the skin. With gradual, consistent nighttime use, the formula refines the look of texture, fine lines and uneven tone while black ginseng, bakuchiol, niacinamide, vitamin C and peptides round out the well-ageing care.

Know the percentage: “Retinal Liposome 2%” is the name and level of the retinal-liposome complex. It does not mean the bottle contains 2% pure retinal.

FORMULA FOCUS

Six ingredient groups for texture, tone and elasticity

Retinal

A vitamin A ingredient that smooths the visible look of fine lines and uneven texture when introduced gradually.

Black ginseng

Provides antioxidant care and supports a firmer, more resilient-looking complexion.

Bakuchiol

Complements retinal in a texture- and tone-refining evening routine.

Niacinamide + vitamin C

Niacinamide and 3-O-ethyl ascorbic acid brighten dull-looking areas and improve visible unevenness.

Three peptide ingredients

sh-Oligopeptide-1, sh-Oligopeptide-2 and sh-Polypeptide-1 support a smoother, firmer-looking finish.

Glycerin + nourishing oils

Glycerin, macadamia seed oil and sunflower seed oil reduce the dry feel that can make fine lines look more pronounced.

IDEAL FOR

A gradual evening treatment for visible signs of skin ageing

Use this serum when your routine needs focused care for fine lines, rough or uneven texture, dullness, visible discoloration, enlarged-looking pores or reduced firmness.

HOW TO USE

Build retinal tolerance without rushing your skin

Cleanse, tone and let skin dry

Use in the evening after cleansing and toner. Apply to dry skin rather than damp skin.

Apply a pea-sized amount

Smooth a small amount over the face and neck, avoiding direct contact with the eyes and lips.

Follow with moisturiser

Gently massage until absorbed, then seal in comfort with moisturiser.

Protect the next morning

Apply broad-spectrum sunscreen every morning while retinal is part of your routine.

Starter schedule

Weeks 1–2Use two evenings per week.
Weeks 3–4Use every other evening if skin remains comfortable.
Week 5 onwardProgress towards nightly use only when your skin has adjusted.
For a gentler start: Apply a thin layer of moisturiser before the serum, then moisturise again afterwards.

RETINAL SAFETY

Keep active nights simple and introduce retinal slowly

Patch test first. On retinal nights, skip other retinoids and strong exfoliating acids, keep the rest of the routine gentle, and reduce frequency if dryness or irritation develops.

K-SECRET Seoul 1988 Retinal Serum FAQ

Does Retinal Liposome 2% mean 2% pure retinal?

No. Retinal Liposome 2% names the encapsulated retinal complex used in the formula; it is not a declaration of 2% pure retinal.

Should I use this serum in the morning or evening?

Use it in your evening routine after cleansing and toner, followed by moisturiser. Apply sunscreen every morning.

How often should a retinal beginner use it?

Begin twice weekly for two weeks. Move to every other evening in weeks three and four if comfortable, then progress towards nightly use from week five only after your skin has adjusted.

What should I do if my skin feels dry?

Reduce the frequency and use the moisturiser sandwich method: moisturiser, a small amount of serum, then moisturiser again.

Can I use the Retinal Liposome 1% Cream over this serum?

Use the serum and retinal cream on separate evenings. Do not stack two retinoid products in the same routine.

Which concerns does it target?

It targets the visible look of fine lines, rough texture, dullness, uneven tone, enlarged-looking pores and reduced elasticity.

How should I store the serum?

Keep it tightly closed in a cool, shaded place. Refrigeration is optional if you prefer a cooler feel on application.
