Purchased in 2025 Made in the USA I think it's a pretty good deal. I'm decluttering my skincare products. ・Product Description The newly released CE FERULIC serum adds Ferulic acid, a new ingredient, to the existing Vitamin C and E. It provides up to 8 times the antioxidant protection against aging caused by UV rays compared to bare skin. Ferulic acid: An active substance found in high concentrations in rice and plants of the mint family. It is an antioxidant for the skin and is also expected to protect against sun damage by absorbing UV rays. *The product may change color due to the Vitamin C content, but this does not affect the product's quality. ・How to Use Apply 2-3 drops thinly to the face, neck, and chest once a day, at night. Follow with a moisturizer. If using in the morning, follow with sunscreen. Please refer to my profile for more information.
