SEOUL 1988 Serum: Retinal Liposome 2% + Black Ginseng

A well-intentioned retinoid serum undermined by questionable formulation choices and the critical absence of pH buffering information. While the formula contains impressive actives—Retinal (a potent retinoid), Bakuchiol (a gentler alternative), Niacinamide (4-5% range suggested), and 3-O-Ethyl Ascorbic Acid (stable vitamin C)—the efficacy score is significantly compromised by several red flags. First, the presence of Retinal at 2% in a liposomal delivery system is promising in theory, but without disclosed pH data, we cannot confirm whether the formula is buffered to minimize irritation; retinoids are notoriously pH-sensitive and require careful formulation. Second, the inclusion of both Retinal AND Bakuchiol simultaneously is redundant and suggests the formula may be hedging its bets rather than optimizing either pathway. Third, Ethylhexylglycerin (a preservative) appears mid-list, which is acceptable, but the formula lacks visible chelating agents (EDTA is present but late in the list) to stabilize the vitamin C derivative. Fourth, Macadamia oil (high oleic acid, 50-67%) is excellent for dry skin but suboptimal for acne-prone or oily skin types—limiting the product's versatility. The liposomal encapsulation of Retinal is a genuine plus for stability and penetration, but without clinical data confirming the concentration and pH optimization, this remains theoretical. The formula reads as a 'kitchen sink' approach: many actives, but unclear synergy or optimization. If you're looking for skincare anti aging products or vegan skincare, this is worth evaluating.
