Reddit mentions of Olay Regenerist Regenerating Serum Fragrance Free 50Ml

This Olay serum contains lots of antioxidants. I know, I was totally overwhelmed at first! If I were you, I wouldn't buy too much at first and wait till you just pick up knowledge and experience as you go along. I bought too much pricey stuff at first! My understanding is that vitamins are antioxidants, as are a lot of plant extracts, eg green tea. This serum is rated Best on Beautypedia: http://www.paulaschoice.com/beautypedia-skin-care-reviews/by-brand/olay/regenerist/_/Regenerist-Regenerating-Serum-Fragrance-Free. They are reviewing the US formulation, but as far as antioxidants etc go, the review would be the same I think. I actually bought the US formula of this serum from amazon.com because I was concerned about the combination of a preservative called DMDM Hydantoin and an 'amine' ingredient in the UK version of the serum. [EDIT On the Olay page you link to, they list an older UK formulation that doesn't containg DMDM Hydantoin and Triethanolamine, but my impression is that the one now available is this one: http://www.amazon.co.uk/Olay-Regenerist-Moisturiser-Regenerating-Fragrance/dp/product-description/B000T9AS5E/ref=dp_proddesc_0?ie=UTF8&n=117332031&s=beauty. I may well be misunderstanding the science here: I don't know what an 'amine' is, I just saw it in the ingredients and guessed].
This is probably me being stupidly paranoid: obviously loads of people in the UK are buying it and it must have been through testing, but in the ingredient dictionary on Beautypedia it raised a theoretical concern about when these two ingredients were combined. You can check it out yourself and see what you think.

HOWEVER, I've been thinking about this and I've started to feel really guilty for recommending anyone anything skin care related on here! I personally have never read any research on antioxidants, SPF or whatever. So, I don't really want to encourage you to spend your money on a serum that might just be snake oil for all I know! I haven't used the serum yet, but I'm not sure that I personally will bother with a serum or with products that don't give me results that I can see with my own eyes once I've used them up. The main positive thing I've seen with my own eyes from skincare products is simply less dry skin after moving to a heavier moisturiser that cost about £1.50 from Boots. I'll probably keep using SPF as my impression is the evidence for aging being linked to sun damage is compelling, but I personally have never read a single paper on it.
NB I haven't tried exfoliation yet: who knows, I might fall in love with it!

Good luck!
