I'm a new listener to the podcast. Thank you for your hard work! I recently started getting into skincare and have heard about this line called The Ordinary. It's kind of a superstar on youtube and some beauty blogs since it launched earlier this month. The selling point for the company and this line is that skincare should be affordable and you shouldn't have to spend lots for these key ingredients--some of which you've mentioned on your show. Is it possible to actually formulate an effective niacinamide, retinol or vitamin c product for these prices? Is it too good to be true?
