Hi Randy and Perry,
I use Beautypedia a lot.. live in Australia and find the information sometimes inconsistent not just because we have brands that aren't in the U.S and vice versa but a lot of popular brand products that are rated highly on Beautypedia have a slightly/altogether different formula in Australia. Why is this?
I realise that there's different regulations in each country.. Le Roche-Posay Anthelios SPF50+ for example has perfectly fine formula in America but in Australia Alcohol Denat is second from the list. Why change a formula needlessly for another country?.. and put something damaging.. is it to cut costs or something? Is there a need for the alcohol?.. or is that the true formula and Americans aren't getting the whole truth?
Also I know drying alcohol is an irritant, oxidising the skin?.. but is it really that bad? By that I mean is it something that dissolves straight away on the skin? Is this still enough to cause damage on a daily basis if it dissolves? Or is it sort of suspended in the formula so it's always there and irritating your skin.. I don't understand why put drying alcohol in an otherwise great formula and as one of the main ingredients, is it the only option or could something better be used?..
Also essential oils, are they still damaging if they're at the bottom of the list? Maybe not one-off.. but on a daily basis.
What is oxygenation? Is it a real thing and do we need it? I thought that Oxygen actually causes oxidation to cells.. or oxidization
.. or maybe I made that word up.
We're always learning about what's new in beauty and finding out about new ingredients we've never heard of before, I look them up but sometimes can't find anything at all/that is straight forward..
Is there a common rule to follow about plant extracts for example? I know to avoid anything citrus (in high concentrations at least?) and pawpaw/papain.. but what about other extracts? Berries - good.. Citrus - not.. etc?
Also are all fruit enzymes an AHA?
And what are Gamma Hydroxy acids? Why aren't they as popular as AHA's and BHA?
