Olay Regenerist Regenerating Serum.. This is your dream if you have an uneven skin tone, wrinkles, lines, etc. I put it on at night after cleaning my face. It has a great scent and it goes on smoothly. After a few uses your skin feels amazing. If you have an acne problem be sure to wash your face well before use because it does contain a small, small amount of oil. This serum also contains some of the same amino acids that are used to get rid of crows feet and to smooth wrinkles.
