I worked at a spa that used Malibu C Transparent-C for seven years. I used it regularly. I a 46 years old and I have no wrinkles. I stopped working at this spa two years ago and had not used Transparent-C until recently when I bought it again and have used it twice now. I can already tell a big difference in my skin. I love Malibu C's Transparent-C and always recommend it to anyone who asks what the best product for aging is.
