K-SECRET Seoul 1988 Boosting Serum — Collagen Complex 7 + Red Ginseng 30ml

Seven types of collagen. One naturally pink serum. Younger-looking skin — starting now. The K-SECRET Seoul 1988 Boosting Serum is a next-generation Korean anti-ageing serum that delivers a 7-type collagen complex to help improve the look of skin texture and suppleness  at every depth — from the surface barrier down to the deeper layers where elasticity is built and lost. Paired with Red Ginseng, beloved in K-Beauty for its powerful antioxidants that refresh skin cells, boost healing, and lift fine lines , this is one of the most complete firming serums in the K-SECRET lineup.

The naturally pink colour comes from Cyanocobalamin — Vitamin B12 — with no artificial colorants and the lightweight, airy texture absorbs instantly without heaviness or residue. Its non-greasy formula absorbs quickly, leaving skin fresh, comfortable, and makeup-ready. 

Why it works:

Collagen Water base — forms a lightweight hydrating base that helps seal moisture into the skin barrier for long-lasting hydration  from the very first layer of the formula

Atelocollagen — a low molecular weight collagen that absorbs well into the skin while remaining low-irritation, delivering deep hydration and improved elasticity 

Desamido Collagen — penetrates the upper layers of the skin to restore suppleness and reinforce the surface moisture barrier

Hydrolyzed Collagen — broken into fragments to absorb well into skin, providing smaller structures to boost natural cell elasticity for better bounce and lifting of fine lines 

Soluble Collagen — large molecule that helps seal the skin barrier and ensures hydration is locked in for plump, long-lasting moisture and a more youthful appearance

Collagen Amino Acids — collagen broken down to its original building blocks, providing skin cells the ingredients to build their own collagen for naturally plumper and smoother skin 

Procollagen — the precursor to collagen synthesis, signalling the skin to produce fresh, new collagen from within

Panax Ginseng Root Extract (Red Ginseng) — rich in antioxidants and healing molecules that refresh and boost skin cell health while improving natural hydration for a plumper, glowing look 

Coptis Japonica Root Extract (Japanese Goldthread) — a traditional East Asian botanical with potent anti-inflammatory, antioxidant, and antimicrobial abilities 

Niacinamide — brightens uneven skin tone, fades dark spots, and refines the appearance of pores

Ceramide NP & Squalane — deliver lasting moisture, help keep skin hydrated and refreshed throughout the day , and lock in the benefits of every other active in the formula

Polyglutamic Acid — a next-generation humectant up to 4x more hydrating than Hyaluronic Acid, binding water at the surface for lasting plumpness

How to use: After cleansing and toning, take 3–5 drops of the serum and spread evenly over the entire face. Gently pat with fingertips until fully absorbed. Follow with moisturiser. Suitable for morning and evening use. Always follow with SPF in the morning.

Suitable for: All skin types, especially dry skin · Loss of firmness, fine lines, and dryness  · Sensitive skin · Fragrance-free · No artificial colorants · Made in Korea 🇰🇷

Why Seoulma recommends it:

Most collagen serums use one or two types of collagen and call it a day. K-SECRET's approach with the Seoul 1988 Boosting Serum is fundamentally different — and smarter. By using seven distinct collagen types at different molecular weights, the formula works on multiple levels of the skin simultaneously. The larger collagen molecules seal and protect the surface, while the smaller hydrolyzed fragments and amino acids penetrate deeper to rebuild elasticity and signal the skin to produce its own fresh collagen. It's a full-depth firming strategy in a single serum.

The Red Ginseng pairing is also beautifully considered. Where most anti-ageing serums lean heavily on synthetic peptides, K-SECRET reaches for one of Korea's most treasured traditional ingredients — Panax Ginseng Root has been central to Korean wellness for thousands of years, and modern dermatology has confirmed what Korean women have always known: its antioxidant and healing properties are genuinely exceptional for mature and fatigued skin.

What surprised us most when testing it was the texture. For a formula this densely packed with actives, it feels remarkably lightweight — almost like water on the skin — and absorbs completely within seconds, leaving that signature soft-plump feeling without any tackiness. The subtle pink hue makes it feel luxurious without being gimmicky, and the fact that the colour comes entirely from Vitamin B12 rather than dye is a detail that matters.

We recommend it especially for skin that is starting to lose density and firmness — that stage where fine lines are deepening, skin feels less bouncy, and your usual moisturiser no longer feels like enough. This serum fills that gap perfectly. Use it consistently morning and evening for four to six weeks, and the difference in skin firmness and overall plumpness will be clearly visible.
