Carol Franck Serum

This is a Carol Franck serum that is firming and emphasizes anti-wrinkle functions. I recommend it more to those with oily skin than those with dry skin. After applying it, your face feels tight and supple, so I think it would be a better fit for oily skin types. Since it is a French product, I heard that it is widely used in famous skin care salons. I highly recommend it.
