I started using Clinique when I was 11 and I STILL use it twice daily. It is perfect for me. I am 50 and no one believes I am 50. My husband is 56 but he has solid white hair and we are often mistaken as a dad and daughter vs hubby/wife. He has great skin but his hair ages him.
I used the products from Clinique that best suited my skin for each stage. Right now I use the Repairwear line.... laser focus, eye cream, night cream and I use Jose Moran Argon Oil. I also use Noxema at night because I love it.
My 18 yr old uses Clinique as well. She too has great skin and a great routine.
Of course other factors come into play such as genetics, drinking a LOT of water, sunscreen, etc.
My mom took me to the dermatologist when I was 11 as a proactive approach and he suggested Clinique. Other things he suggested were Cetaphil and Purpose.
Also, keep in mind that products do seem pricey. I may pay $60 for a container of cream that I use twice daily and if you use the proper amounts, it should last you a good 6 months. The Argon oil I bought is a small bottle and I use 2 drops twice daily and I've had it over 4 months and it is still half full.
Work with a brand that works with you as well. For instance, clinique stands by their product but there are some people who cannot use it. They will fully guarantee the product and you will get a refund or exchange if you just talk to them vs getting angry over wasted money again and throwing the product in a drawer.
