"ALA does not work at concentrations lower than 4% and vitamin C needs to be at least 10%."
INCORRECT: PH level determines effectiveness of BHA and AHA. ALA is not an effective exfoliant even in higher concentrations. BHA exfoliates through the pore. AHA only exfoliates the surface. Vitamin C has a cumulative effect. So higher concentrations are not needed if used over long periods of time. Same goes for products like Retinol. Rx levels of retinol, etc. are more effective short-term, but they can also be very irritating at those levels which leads people to stop using them. High levels of Vitamin C can have the smae effects. Long-term it's a matter of consistency.
All exfoliants cause some irritation when first used. And Retinol isn't an exfoliant. That is the first clue that you're not getting good information from a website. If you doctor thinks Retinol is an exfoliant, then you need to get a new doctor.
"Dr. Denese Day Cream/SPF 30 (Zinc Oxide 7.5%, Octinoxate 7.5%) - if you are going to use a chemical sunscreen full of "nasties", at last use one of the European sunscreens with better UVA protection. See the Sun Protection forum for loads of ideas."
INCORRECT: "European" sunscreens use the same effective ingredients as sunscreens in the U.S. How do I know? I'm from Europe. There is a difference between a sunscreens and sunblocks. The author of your website should know this. It's chemistry 101.
My advice is that you go to a credible website that bases it's opinions on scientific research backed by double blind clinical trials and peer reviewed studies. The only wesite that even comes close to this is www.paulaschoice.com. All the other websites are just a bunch of cackling women with no basic knowledge of chemistry spouting nonsense. Sorry, but these are facts.
