K-Secret Seoul 1988 is an anti-aging eye cream built around a 4% retinal liposome complex, a next-generation retinoid known for targeting fine lines, crow's feet and loss of firmness around the eyes. It's paired with fermented bean (soybean) extract for brightening and tone-evening benefits, along with bakuchiol, vitamins C and E, and peptides to support elasticity and collagen. Best suited for mature or aging skin looking to address dark circles, crepiness and wrinkles, though those new to retinoids should patch test first since retinal can be more potent than retinol. Recommended for nighttime use, since retinal can degrade in sunlight; apply a small amount around (not directly on) the lash line and pat in gently, following with sunscreen in the morning.
