“Vitamin A derivatives like retinal are kind of like the powerhouse ingredients in skincare”10:37–10:42

“This is a really good product if you are more experienced with retinoids or if your skin is just really not sensitive to them”12:49–13:04

Brand note

Retinal-based eye creams and serums for experienced retinoid users.

K-Secret is a K-beauty brand that leans hard into retinal, specifically around the eye area. The SEOUL 1988 Eye Cream is the anchor here — a 4% retinal liposome formula that creators describe as genuinely gentle for a retinal, with a controlled dispenser and moisturizing feel. It's not for beginners: the consensus is that this suits people who already know how their skin handles retinoids. The brand also makes a cleansing oil and eye patches that get positive mentions, but the retinal line is clearly the story.
