I read a really good article in a magazien once (probably the only beauty artile I've ever found interesting)
A plastic surgeon wrote it and listes all the things that could be dealt with without surgery and what needed surgery etc if you wanted real improvement.
He said that after the age of 30 or so a good skin regime would make a difference to fine lines and wrinkles.
He said you need to
Cleanse wash the skin well (non soap cleanser or even mild soap like dove is fine) - Rinse with warm water, Then lather again and rince with cold water to close up pores.
Then use a good quality retin a (on prescription) or retinol (over the counter) product. Get one that is as expensive as you can afford. Use that.
Then use a good quality moisturiser with sunscreen or (either a combined one or put the moisturiser on followed by the sunscreen)
That is it. He did say the retinol is quite strong and some people have a sensitive reaction to it but if you are OK with it use it as it really does make a difference to wrinkles if used regularly
