What vitamins should take a 40-year old take to look as young as possible?

Answer by Johnty Andersen:

A lot of good advice here already but I agree regarding Retin A or Tretinoin See http://www.webmd.com/drugs/2/drug-3956/tretinoin-top/details is good for the the skin 0.1 if you can stand it 0.05 to play safe but it is great for sun damage. D3 yes 100% and fish oil Omega 3 yes that too but vitamins are not the the only thing sunscreen – but not being sun phobic I love the beach – to protect the skin and enjoying life are the key because at 40 you could live a very long time see http://www.sens.org and a final tip try http://www.international.boots.com/en/No7-Men-Protect-Perfect-Intense-ADVANCED-Serum_1610452/ I use it and it's great for girls too and better than the women's equivalent. At 40 keep fit, enjoy life, have fun and focus on a long life and take a few tips – stress when you are my age!
