K-Secret - aeripeach review for Seoul 1988 Serum: Retinal Liposome 2% + Black Ginseng

For my first experience using retinal, I’m so impressed with the results! My skin was already used to retinol, so I didn’t need a long adjustment period, and there was no irritation at all. The biggest difference I noticed? Smoother, brighter skin and fine lines disappearing! ✨ Right now, I’m using it twice a week, alternating with a 0.5% retinol serum on other days, always pairing it with a good moisturizer to keep my skin hydrated. Super happy with how my skin looks and feels! If you’re new to retinal, I recommend starting with the sandwich method and using it just once a week at first.
