Itty Bitty Midi Committee: An Acid Kit ($99 value) A limited-edition kit with a complete set of serums to leave your skin hydrated, smooth, and downright glowing. Welcome to the Committee what else to know The skin is an acidic environment, which means it recognizes—and loves—acids. So we made a travel-size set with the acids it loves. C-Firma (15 ml/.5 fl oz) brightens and firms with 15% l-ascorbic acid, aka vitamin C. B-Hydra (15 ml/.5 fl oz) hydrates with pro-vitamin B5 and sodium hyaluronate, a smaller, more absorbable derivative of hyaluronic acid. T.L.C. Framboos (15 ml/.5 fl oz) exfoliates with 10% alpha hydroxy acids (AHAs) and 1% salicylic acid (a beta hydroxy acid, or BHA). 100% free of essential oils, silicones, fragrance/dyes, and solvent alcohols.
