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! Read more

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. Read more

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 Read more
