Item model number : SEOUL1988SERUM
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.

Good retinal, Great price
This serum has been a 10/10 for me. I love the ingredients, and it makes my face so smooth, glowy, and soft in the morning. In conjunction with vitamin C in the daytime, and this in the evening, I’m definitely seeing a reduction in fine lines. I love the pump bottle, which I find is so much more hygienic than the pots of cream. For the price, you really can’t beat it.

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.

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!

One of the best retinols out there
This is by far one of the best retinols I’ve ever used. What I love about this product is that when applying it glides onto the skin easily and absorbs without leaving any sticky residue. Immediately after the first use I noticed the next morning my skin was left feeling super soft and smooth. I’ve tried other store-bought retinols and never notice a difference to my skin like the prescription version until I tried K-Secret Seoul. This is now a part of my weekly skin routine.

So far so good
This product has not broken me out. I had my dermatologist check it and they said there was nothing acne, causing in it. This product has not tried me out since using it, and I have noticing some brightening and firming affect since starting retinol. I do like the price range. It’s not overly expensive like some luxury brands.

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
