Product recommendations simple Safe skincare routine?

Any recommendations for the safest products for someone that's never done/stuck to skincare for more then 2 days every 8 months ish (for my partner, 28, not me and yes that goes for spf too they never use it and struggle to trust skincare but they finally want to start)? Preferably not to expensive, big plus for any recommendations for nordic products or products we can get in Scandinavia. struggling to find something that seems simple, minimal and safe to just try out to not risk any bad reaction. Had previous reactions to serums and toners from the ordinary, benton, cosrx and cerave blemish gel with things like Niacinamide and aha/bha. do also have acne with painful cysts but don't want to treat that without seeing the doctor. Just want to get a basic starter routine that won't risk clogging or more acne and just treat the skin as if it is extremely sensitive and very dry with oiliness.
