PCA skin hyaluronic acid boosting serum. 1 fluid ounce sized bottle and it is 95% full. I used it twice. My sensitive skin got a rash. But my skin is extra funny acting these days. Expiration date is 07/2024 which is on the box and the bottle. Also both the box and the bottle have matching serial numbers and expiration dates. I opened it not even a month ago. Ingredients etc. are in the pictures. The box kind of got massacred from trying to stuff the pamphlet back inside. Retails for $124!
