since you are only 20 and have no wrinkles then the best advice for you is to always wear sunblock stay out of the sun eat non-processed foods and drink 4-6 glasses of water a day. most wrinkles come from the sun. so your best anti-wrinkle cream if you don't have wrinkles is sunblock. at around 30 it does make sense to start with a nice anti-wrinkle cream. using expensive products is ok if you can afford it since they will provide good moisture and they feel good. moisturizing daily will keep the skin supple at any age. but only sun avoidance will really make a giant difference over time as far as line prevention is concerned.
i am 20. is that too young to consider anti-wrinkle night cream as a preventative?
