K-SECRET SEOUL 1988 Retinal Serum: Retinol Serum for Face Anti Aging Wrinkle Care - 2% Retinal Liposome Black Ginseng Niacinamide Bakuchiol Vitamin C & 3 Peptides - Korean Skincare Fragrance Free 30mL

Absolute HOLY GRAIL Retinal! I bought this on a whim, and now I am hooked. It's light, it absorbs quickly, it has no scent at all, it has mad my skin bright, tight, smooth and firm. It's helped with hydration, it's evened out my skin tone, smoothed fine lines and given a beautiful radiance. I have it on auto order because I don't want to be without it! It's a great value for a high strength retinal. It lasts for quite a while because a little goes a long way! Super recommend!

I have been using this for a couple weeks now and I see a difference in my skin. I bought it for blemishes and wrinkles as I am over 50 my skin doesn’t look as good as it used too. The blemishes have faded and the wrinkles are softer - not as defined. I am hopeful with continued use it will improve even more. Each night I cleanse my face then apply the Seoul 1988 to my entire face. A little goes a long way. The directions say to ease into using it, but I have not had a problem with dryness or irritation. I recommend doing a test area first - not on your face. I did a large patch maybe 6 x 6” on my upper chest my first time. Each morning I cleanse my face then apply a moisturizer while my face is still damp which really makes a difference I think. Great product to add to your skincare routine. In case you’re wondering about odor, there is none. Creamy light yellow cream and it goes on smoothly with no greasy feeling. It doesn’t even feel like you put any on.

This serum is a gentle but effective retinal formula that smooths texture, fades fine lines, and brightens the skin. It uses encapsulated retinal (stronger than retinol) plus niacinamide, bakuchiol, and peptides for anti-aging benefits without irritation. Most users notice softer, firmer skin within a few weeks. It’s well-tolerated, even for sensitive skin, though a mild purging phase is possible at first. Great for those upgrading from retinol—just start slow and use sunscreen daily!

I am thrilled with the K-SECRET SEOUL 1988 Retinal Serum! The 2% Retinal Liposome has significantly improved my skin texture and reduced fine lines within just a few weeks. The serum absorbs quickly and keeps my skin hydrated without any greasiness. I love that it uses advanced liposome technology to minimize irritation, allowing me to build tolerance gradually. Plus, it's dermatologist-tested and free from harmful chemicals, which makes me feel great about using it. Overall, this serum has transformed my skincare routine and given me more youthful-looking skin. Highly recommend it for anyone seeking effective anti-aging results!

I’ve been using the K-SECRET SEOUL 1988 Retinal Serum for a few weeks now and I’m already seeing a noticeable difference in my skin’s texture and brightness. It goes on smoothly, absorbs quickly, and hasn’t caused any irritation—which is a big deal for my sensitive skin. I love that it includes powerful ingredients like retinal, bakuchiol, and niacinamide. My skin feels firmer and looks more radiant. Definitely a new staple in my nighttime routine!

I have been using this product on my over 60 skin for a few weeks and can see a difference in my lines/wrinkles. Have used other expensive products over a long period of time and did not see the results I am seeing with this serum. Order more yesterday and also trying the eye cream!

This product arrive quickly and in excellent condition. It's has a yellowish cream that is almost odorless. It does makes my skin soft but it wasn't as effective as I anticipated.

Value for money is great. Quality is good. Stickness is great. Scent is nice. Ingredients is amazing.

Good product for acne prone or closed comedones/milia skin. Like the fact it is not just retinoids but also peptides and niacinamide. Good overall serum. Wish it was cheaper though

I'm 39. With some fine lines around my mouth, and neck lines. I also have some hyperpigmentation along my jawline. This serum is wonderful. Feels nice on the skin. Absorbs quickly. After applying, my skin feels firm and hydrated. I particularly love that this product virtually gives me no irritation at all, in comparison to retinols. Remember, this is retinal, with an A. And it's packed with powerful ingredients that address various skin issues. Did you know that they don't use retinol in Korea? Koreans don't believe in causing any damage to the skin. Just an interesting tidbit. And retinal works 11 times faster than retinol, and is way less irritating. I've used various retinols that have all destroyed my skin. I will not be going back to retinol. I've been using it daily for about a month along with the Seoul 1988 snail mucin. This is what I have observed: My face is brighter and smoother. Hyperpigmentation along my jawline is lighter. Skin on my face and neck are firmer. My fine lines around my mouth are barely noticeable. My necklines are softer. This product does deliver on its promises. I hope with continued use, it will continue to improve my skin. It's refreshing to find a product that delivers, and doesn't make false promises.

This serum is amazing. I have tried many products but this is the best. Skin is smooth when used once or twice a day.

Iv had it for a month now,and haven't noticed any changes.not sure if am not using it corrctly

The best skincare product I have ever purchased. I can see the difference within 10 days.
