The Drunk Elephant Protini Powerpeptide Resurfacing Serum is a daily exfoliating facial serum formulated with 10% lactic acid and an advanced signal peptide complex. Available in a 1 fl oz (30 mL) bottle, this serum gently resurfaces and firms skin with minimal irritation, making it suitable for most skin types seeking a powerful yet approachable alpha hydroxy acid treatment. It is formulated at a skin-friendly pH of 3.5.
The serum combines lactic acid — a mild AHA derived from sugar fermentation — with a nine-peptide signal complex that works to plump and restore bounce to skin. Snow mushroom extract (Tremella Fuciformis Polysaccharide) provides potent antioxidant protection and intense hydration. Additional key ingredients include squalane, sodium hyaluronate, panthenol, and a full amino acid complex (alanine, arginine, glycine, histidine, and more) to support skin's natural moisture factors. Clinical studies demonstrated that 100% of participants showed improvement in skin elasticity after eight weeks, 100% had more radiant skin after four weeks, and 93% had smoother skin after eight weeks.
To use, shake gently before applying to a clean, dry face, avoiding the eye area. The serum may also be applied to the chest and backs of hands. Follow with your choice of moisturizer. Daily sunscreen use is recommended while using this product and for one week after ceasing use.
