I am sorry to say this - but you cannot "Prevent" wrinkles.
Well - you can - stay out of the sun and keep your skin perfectly moisturised. I have seen an 80 yr old woman who looked like she was 50!! Her plan - no tanning, when outside in the sun - you have sunscreen and an umbrella, and she moisturised with basic cream.
They are inevitable.
This is what I do know...
Any form of acid - whether it is an AHA or BHA can help with the appearance of wrinkles - but that is from the outside. All they do is take off the dead skin. Most "anti wrinkle" creams have a tiny tine amount of acid of some form - but what is sold over the counter isnt of any great benifit at all.
Salicylic Acid. The active ingredient in aspirin. It is used in cosmetics as an exfoliant, and is the only source of beta hydroxy acid (BHA). As an exfoliant, in concentrations of 8% to 12%, it is effective in wart-remover medications. In concentrations of 0.5% to 2% it is far more gentle, and, much like AHAs, can exfoliate the surface of skin. Because BHA is related to aspirin (both are salicylates), it retains some of aspirin’s anti-inflammatory properties.

I dont think that a doctor would make a claim like this - other wise they would have done this a long long time ago.

Dont believe everything you see or hear - If it is too good to be true, probably is. You should hear what we get told!! Some of the things that people have told us that they have done to get rid of things.... it would blow your mind.
