I'm a faithful user of Clinique and have been since I was about 11. My 14 yr old daughter uses it faithfully now.
Of course I used whatever product was best for my "stage" as I got older. Now I use the Repairwear Series and I love it. I use the Day and the Night. I ALWAYS use Clinique sunscreen daily as well.
It is around $40-$50 for the product but it lasts you a long time (6+ months) Completely worth the money. Buy it when one of the department stores has the gift with purchase and you get to try other products as well.
Yes, if you do not like the product you purchase, Clinique will take it back. People are very surprised when I admit my age due to my skin and regular upkeep...
