FORMULATED WITH ADVANCED RETINAL & LIPOSOME DELIVERY SYSTEM: Our formula applies a liposome delivery system to Retinal, the next-generation form of Retinol that works up to 11 times faster. This technology enhances ingredient stability and boosts absorption for more visible results.
INFUSED WITH RETINAL LIPOSOME 2%: helps reduce the look of fine lines, uneven skin tone, and rough texture for smoother, more radiant skin.
RETINAL BOOSTING COMPLEX: Powered by Black Ginseng Extract, Bakuchiol, 3 Peptides, and Niacinamide, this antioxidant-rich formula refines pores, smooths skin texture, and promotes a more balanced complexion.
RETINAL USAGE TIP: 1. Nighttime use is recommended, as Retinal may oxidize when exposed to sunlight. If used during the daytime, make sure to follow with sunscreen. 2. To build Retinal tolerance, start by using it twice a week during the first 1–2 weeks, then gradually increase frequency as your skin adjusts.
HOW TO USE: 1. After cleansing and toning, apply an appropriate amount evenly over the face and neck. 2. Gently massage until fully absorbed, then follow with a moisturizer.

My favorite retinal serum!!
I love this serum! I’ve struggled with using retinal and retinol products due to drying out and some irritation, but this serum is both moisturizing and pairs well with moisturizers / hydrators and is gentle on my skin while also being very effective. My skin looks and feels great, and I’m just thrilled to be able to successfully use a retinal product routinely since it’s so valuable for anti-aging. There’s a light, pleasant scent and it absorbs & layers flawlessly. There no tackiness and leaves skin soft. Love it so much I have a subscription.

Awesome !!!
K Secret Retinal Serum has officially earned a spot in my nighttime routine. Unlike some retinal products that feel heavy or irritating, this one goes on silky smooth, absorbs quickly, and doesn’t leave my skin feeling tight.After a few weeks of consistent use, I noticed my skin looking brighter, smoother, and more even-toned. Fine lines around my eyes and forehead started to soften, and my overall texture feels more refined. It gives results without the harsh side effects—no flaking or redness, just a gentle but effective boost.I also appreciate the thoughtful formula: it’s lightweight, layered well under moisturizer, and didn’t clog my pores. The pump packaging makes it easy to use the right amount without waste.If you’re looking for a retinal serum that delivers visible results while still being kind to sensitive skin, this is definitely worth trying.

Performance
It seems to be working, takes a longer time than expected based off reviews but nevertheless it works so it’s apart of my skincare routine

Excellent RetinAL product!
Not irritating because of its formula as a retinAL (but I’ve used retinOL regularly, so my skin has gotten used to it) , excellent price, and actually works. Worth trying

🧴 Seoul 1988 Serum – Retinal Liposome 2% + Black Ginseng
This serum feels lightweight and absorbs quickly without leaving a greasy or heavy finish. It provides a gentle warming/active sensation typical of retinal products, but without excessive irritation. With consistent use, it helps improve skin texture and overall smoothness. The addition of black ginseng gives it a revitalizing, skin-strengthening feel, making it a good option for nighttime anti-aging routines.

Love it
I am so impressed with the KSecret Seoul Retinal Serum—it has quickly become one of my favorite skincare products. The texture is lightweight and silky, making it really easy to apply and layer with the rest of my skincare routine. It absorbs beautifully without leaving any sticky or greasy feeling on the skin.What I love most is how gentle it is. Retinal (a stronger form of retinol) can sometimes be irritating, but this formula is incredibly soothing. I didn’t experience any redness or dryness, just gradual, noticeable improvements. After just a few weeks of consistent use, I started seeing a real difference in my skin’s texture and tone. My complexion looks smoother, more even, and I’ve noticed that some of my fine lines have softened.The packaging is also really nice—sleek and hygienic with a pump that gives you just the right amount of product every time. Plus, a little goes a long way, so it lasts longer than I expected.If you’re looking for a retinal serum that delivers results without irritating your skin, I highly recommend the KSecret Seoul Retinal Serum. It’s effective, gentle, and makes my skin look healthier and more radiant. Will definitely repurchase!

“2% retinal liposome” = .02% retinal
Buy this if you wanna skip retinol and jump right to retinal.Do NOT buy this if you’re graduating from retinol to retinal. I purchased in mid May, we’re now in late August and I haven’t seen ANY changes in my skin. Admittedly, I hadn’t seen the word “liposome” before so I thought it was just a fancy way to deliver the retinal deeper into the skin…”2% retinal liposome” = .02% retinal. Meaning it’s great for people with sensitive skin and/or new to retinol/al.No noticable scent. The texture and feel was great…you know how butter feels when you put it in the microwave long enough to soften (but you maybe let it go for a little longer lol)? That’s how smooth and soft it felt when applying.Read: 3 stars here isn’t meant to be negative, just had an average experience with this.

Das Serum ist unglaublich, die Haut ist perfekt mit Feuchtigkeit versorgt, feine Linien und Falten geglättet.Zu Testzwecken habe ich das Serum auf einer sehr schweren Verbrennung an meiner Wade angewendet. Dank des Serums habe ich keine Narbe, nur eine leichte Verdunkelung der Haut Das Serum ist einfach genial
