What’s missing in my routine?

I’m 33 with seborrheic dermatitis so my skincare needs to be super uncontroversial! I.e no malasezzia feeding/allergenic ingredients, no alcohol, no fragrance, etc.

As well as having sec derm, my skin is combination with enlarged pores on my t zone and a little dehydrated.

Any advice for exfoliates, moisturisers, retinol products (because I need to start looking at anti ageing!), any products you think I’m missing?

:)
