Circling back to JDF I think I take issue with her comments partially because she is critcising someone else's routine and their personal choices about how to care for their skin. Women get slated enough for looking after our skin and wearing make up. She's vain if she does it for herself or she is doing it to attract a man/attention. If she doesn't look after her appearance she has let herself go
Everyone is perfectly entitled to use whatever products they want on their skin so achieve the results they want. If CH wants to use Retinol at night and uses products to counteract the side effects in the morning that is up to her. She didn't tell her followers these are the only products you should use if you are using Tret/Retinol she showed a routine (it does piss me off when she tells her followers to buy something without giving it a proper review).
As I've said above I think that the routine CH posted is probably a pretty normal routine for someone who is taking care of their skin and I feel JDF was being quite judgemental about it

JDF can do what she feels is right for her skin but I don't think criticising other women is the way to go about putting her point across.
