K-SECRET Retinal Serum 2% Liposome — 30ml Night Repair with Niacinamide & Black Ginseng for Fine Lines and Texture

K-SECRET SEOUL 1988 Retinal Serum is a nightly facial serum that delivers 2% retinal in a liposome delivery system to visibly refine texture, smooth fine lines, and even skin tone.

This serum combines a potent 2% retinal concentration with a liposome delivery vehicle and supportive actives — niacinamide, bakuchiol, peptides and a concentrated black ginseng extract — to balance efficacy with stability and skin comfort. Designed by K-SECRET for targeted skin-surface renewal, the formula aims to accelerate retinal performance while reducing irritation often linked to retinoids. Follow usage guidance to build tolerance and protect skin with sunscreen if used during daytime.

How does this retinal liposome serum work to improve skin texture?

The liposome technology in this serum surrounds retinal molecules so they penetrate more evenly and remain stable until applied. Retinal acts faster than traditional retinol, and in this formula it’s paired with texture-supporting ingredients to refine pores and smooth rough patches.

• 2% retinal concentration for advanced skin-surface renewal
• Liposome system enhances retinal stability and absorption
• Niacinamide and peptides help even tone and strengthen skin barrier
• Black ginseng and bakuchiol add antioxidant and balancing support

When and how should I introduce this serum into my routine?

Start conservatively to let skin adapt: apply at night twice weekly for the first 1–2 weeks, then increase frequency as tolerated. Avoid daytime use unless you follow with broad-spectrum sunscreen, since retinal can be sensitive to sunlight.

• Use after cleansing and toning, before moisturizer
• Apply a small amount to face and neck, massage until absorbed
• Nighttime recommended; use sunscreen if exposed to daylight
• Increase frequency gradually to minimize irritation

What supportive ingredients are included and what do they do?

Beyond retinal, the formula contains niacinamide for tone and pore refinement, bakuchiol as a gentler retinoid-alternative complement, and three peptides to help the skin look firmer. A high-percentage black ginseng concentrate supplies antioxidant-rich plant actives that support overall resilience and radiance.

• Niacinamide: reduces appearance of enlarged pores and evens tone
• Bakuchiol: complements retinal with soothing, retinoid-like benefits
• Peptide blend: supports surface firmness and texture smoothing
• 58% black ginseng: antioxidant support and skin vitality

How should sensitive or reactive skin proceed with this product?

Sensitive skin types should build up tolerance slowly and monitor for signs of irritation. If redness or excessive dryness occurs, pause use and reintroduce at a lower frequency or pair with richer hydration to support barrier recovery.

• Begin twice weekly for 1–2 weeks, then increase slowly
• Combine with a gentle, hydrating moisturizer to reduce dryness
• Stop use if severe irritation occurs and consult a professional
• Always use sunscreen the day after application when exposed to sunlight

Who is this for: K-SECRET SEOUL 1988 Retinal Serum is aimed at adults seeking an advanced, clinically-minded nighttime treatment to refine fine lines, improve uneven texture, and brighten complexion without sacrificing ingredient stability. It suits tolerant skin types and those experienced with retinoids who want faster-acting retinal in a stabilized liposome delivery format; sensitive or novice retinoid users can still benefit by introducing it gradually and using supportive moisturization and sun protection.
