K-SECRET Seoul 1988

The K-SECRET Seoul 1988range brings together the retinal skincare products from the Korean brand K-SECRET, designed for skin showing its first signs of fatigue or loss of firmness. This selection includes serum, eye cream, night cream, and essence, all formulated with retinal liposome, a form of vitamin A that K-Beauty adopted before most Western brands due to its skin tolerance. The products available here cover several concentrations, from 1%for skin unaccustomed to retinal up to 12%in a concentrated shot.

This selection includes only the Seoul 1988 products currently available at Holy Skin, ranked by actual popularity rather than marketing prominence. K-SECRET's retinal liposome combines this form of vitamin A with complementary Korean active ingredients, such as black ginseng, fermented rice, or snail mucin, depending on the product. Here you'll find everything you need to build a progressive anti-aging routine, from entry-level serums to the most concentrated formulas.

How to choose your K-SECRET Seoul 1988 skincare product?

Three criteria really matter: your experience with retinal, the area you want to treat, and your skin's sensitivity. The K-SECRET Seoul 1988 range offers concentrations from 1% to 12%, with formats dedicated to the face and eye contour. For a precise understanding of how retinal works, our dedicated articlegoes into more detail.

Serum, cream, or eye contour: which format to choose?

The 2% liposome retinal serumtargets the entire face and is suitable for a first retinal routine. The 1% liposome retinal + fermented rice creamis a softer option for night application, designed for skin that is new to the active ingredient. The eye contour creamis reserved for this thinner area and should never be applied to the entire face.

Retinal Liposome 1%, 2% or 12%: which concentration for your level?

Below 2%, K-SECRET retinal is generally used as an introduction, 2 to 3 times a week in the evening, allowing the skin to get used to it. The Advanced Shot 12%is for skin already accustomed to this active ingredient, used as a targeted treatment rather than systematic daily application. In between, the Cream Snail Mucin 93% + Riceallows you to alternate with a non-retinal moisturizing treatment on rest days.

Is K-SECRET Seoul 1988 suitable for sensitive skin?

Retinal remains an exfoliating active ingredient and can cause tightness in reactive skin at the beginning of use, regardless of the brand. K-SECRET's liposome structure is presented by the brand as more tolerable than classic retinol, but very sensitive skin benefits from starting with the 1%concentration and spacing out applications during the first few weeks.

Your opinions on K-SECRET and Holy Skin

Trustpilot

Which is the best K-SECRET Seoul 1988 treatment?

The choice mainly depends on your experience with retinal. For first-time use, the Retinal Liposome 2% + Black Ginseng Serumremains the most reasonable entry point. To target fine lines and sagging around the eyes, the Eye Cream Retinal Liposome 4% + Fermented Beanis designed for this more delicate area. If your skin already tolerates retinal well, the Advanced Shot Retinal Liposome 12% + Black Riceis the most concentrated format in the range.

    I MAKE MY DIAGNOSIS

    Complete your K-SECRET routine

    K-SECRET Seoul 1988 covers serum, eye cream, cream, and sun protection, but not cleanser or toner: the line focuses on retinal treatment, not the first two steps of the routine. For retinal to work on clean, prepared skin, start with a Korean facial cleansersuitable for your skin type, then a Korean tonerto rebalance pH before applying K-SECRET serum or cream. Order matters: cleanser, toner, then retinal, never the other way around.

      Holy Skin tips for making the right choice

      Cédric, co-founder of Holy Skin, monitors sales and customer feedback on the K-SECRET range since its introduction to the catalog.

      “With K-SECRET, what we see in orders is that the 2% serum almost always serves as an entry point before customers move on to the 12% shot a few months later. The most common mistake we hear about is starting directly with a high concentration hoping for faster results.”

      The most effective approach is gradual progression, not maximum initial concentration. If you're unsure about your starting point, the free skin diagnosiswill guide you to the concentration best suited for your current routine.

      Frequently Asked Questions about K-SECRET Seoul 1988

      checkbox

      What is the K-SECRET Seoul 1988 brand?

      K-SECRET is a Korean skincare brand. Seoul 1988 is the name of its flagship line, focused on a single main active ingredient: liposome retinal.

      This technology is available in various concentrations depending on the product, from face serum to eye contour cream, to target the first signs of aging: fine lines, sagging, and loss of firmness.

      checkbox

      How often should I use K-SECRET Retinal?

      The frequency mainly depends on the concentration and your experience with retinal. Initially, 2 to 3 applications per week in the evening are sufficient, to allow the skin to get used to the active ingredient.

      Once tolerance is established, daily application in the evening is possible with the lowest concentrations in the range. The Advanced Shot 12% format is more suited to occasional treatments than to systematic daily use.

      checkbox

      Where are K-Secret products manufactured?

      As a precaution, retinoids, including retinal, are generally not recommended during pregnancy and breastfeeding. This is a broad recommendation in dermatology, not specific to K-SECRET.

      If you are pregnant or breastfeeding, the safest advice is to consult your doctor or midwife before incorporating a retinoid active ingredient into your routine, regardless of the brand.

      checkbox

      What are the best K-Secret products?

      Yes, the range includes a Seoul 1988, Pine Tree + Ceramide sunscreen, designed for daily use in conjunction with retinal treatments.

      This is an important clarification: retinal increases the skin's photosensitivity. Daily sun protection is therefore recommended alongside any routine including this active ingredient, both in summer and winter.

      checkbox

      Where can I find K-Secret products in France?

      This is the question we are asked most often about this range, and the short answer is that liposome technology generally delivers on its promise of tolerance, with nuances depending on concentrations and skin types.
