Ask Liz: How do you know when your skincare is and isn't working for you?

Skincare is so personal that it’s almost impossible to tell which ingredient/s in your products cause your skin to react positively or negatively. And then of course there are also products that by their very nature cause your skin to “purge” in order to clear out pore blockages, such as those with chemical exfoliants (acids) and retinol. It can get confusing that even for me it’s hard to tell, but I do have some advice for you!
