Skin care advice

Hello, hoping for some advice.

Age 39, currently

Day time: I shower daily due to my job and use carbon theory face soap, then, Nivea factor 50 face suncream if I'm going to be outdoors. Otherwise I use a moisturiser with SPF 30.

Night time, cleanse with cerave hydrating cleanser, then I use dermatica with 15% azelaic acid and 4% niacinamide.

I have mostly balanced skin, sometimes a little dry on my tzone, I also have quite red skin on the cheeks with the occasional spot, likely rosacea.

Is there any better suggestions or alternatives especially for the dermatica as for £26 for a small tube it doesn't last long.

Thanks.
