Skin of any age, only needs to be clean, hydrated and protected from the sun. You're 2/3 of the way there. Micellar is a makeup remover, but not a cleanser, as in it leaves a film on the skin that needs cleansing off afterwards. It's fine as a quick fix, but it's not, ultimately, a very nice product. I think in years to come it will die a death (see also facial wipes)
Two scientifically proven ingredients to think about incorporating would be a vitamin C in the morning, and a vitamin A in the evening.
If you start with an entry grade retinoid (most high street "retinol creams" that don't specify percentages, stand at around 0.3 and that's entry grade. N7, if that's the brand you're interested in, do a nice 0.3 and then a higher % 1% that you'll need to work up to. Remember vitamin A is a long game thing. You won't notice immediate effects, and you won't look 20 years younger. You'll just have skin that looks glowing and bloody good for your age. I started with various retinols, then moved up to tret, but have now gone down a step to retinAl and that's where I'll stay. That's over the last 5-6 years though. Nadine Baggott has some excellent retinoids videos where she explains the differences between retinol, granactive, retinal and retin A.
Hyaluronic acid is just a hydrator, and not an active acid, despite the name so can be used any day, all day. Some skins like it, some don't. Tbh, it's in everything anyway these days, so whether an extra product is needed is up to the individual. I've got dry 58 year old skin, and sometimes use it.
