This is the gold standard in Vitamin C. This is 100% real. Still sealed. Ive never bought or sold skincare online like this- but this is legit and a steal for anyone into medical grade skincare. I bought 3 CE Ferulic when a local spa went out of business. I don’t think I’ll use all 3 by end of next year when the batch code is up. So selling two of them. Potent antioxidant serum with easy-to-use dropper. Boosts skin health effectively.
