Ksecret SEOUL 1988 Eye Cream : Retinal Liposome 4% + Fermented Bean Dupes & Cheaper Alternatives
From 7 Reddit threads · Updated November 11, 2026
4% retinal targets fine lines quickly; eye-area irritation and dryness remain possible. The catch: active formula may irritate or increase dryness without careful use. Here's what Redditors reach for instead.
The short answer
Best Overall AlternativeBeginner-friendly retinal with genuine HG reports · $11.50 · 30 ml
Best Cheaper AlternativeCaffeine visibly depuffs tired under-eyes · $5.97 · 14.8 ml vs $15.40 for the original
#1
Best Overall Alternative
- Size: 30 ml
- Price per ml: $0.38/ml (original $0.51/ml)
The why
A retinal eye serum that layers neatly and earns Reddit reports of gradual smoothing and brighter under-eyes. Studies found the reviewed active can reduce acne, but they do not test eye-area results; dryness makes slow introduction essential.
One minus
Dryness and flaking can make under-eyes look worse
Good forCombination Skin, Oily Skin
The original, at a glance
- Why people love it
- 4% retinal; fine lines visibly improved within three weeks
- Price
- $15.40 · 30 ml · $0.51/ml
#2
Best Cheaper Alternative
- Size: 14.8 ml
- Price per ml: $0.40/ml (original $0.51/ml)
The why
A lightweight caffeine-and-hyaluronic-acid gel for morning under-eye hydration, comfort, and temporary puffiness reduction. It makes sense for dehydrated or swollen eyes, but genetic or deeply pigmented dark circles may barely change, and some users report shine or eyelid bumps.
One minus
Dark circles often stay unchanged, especially genetic darkness
Good forCombination Skin
#3
Same Family: Retinoids
The why
A retinol stick with squalane, glycerin, ceramide NP, and sodium hyaluronate targets fine lines around the orbital bone. It suits experienced eye-area retinol users wanting a swipe-and-go format, but getting too close to the eyelid can trigger irritation.
One minus
Eyelid proximity creates a real irritation risk
Good forSensitive Skin
