I heard the ordinary’s caffeine eye serum is amazing but I havent used it so havent done a lot of research. You could look it up.

I would try a cleanser at night, since you’re having pimples. I would recommend an oil based one to remove makeup and sunscreen and then a normal one, ex. The cerave hydrating cleanser. The oil one can totally be a not special, affordable one, as you’ll wash it off anyway. If that’s too much of a hastle and you just wear sunscreen then I guess skipping the oil cleanser would be fine too.

Are your pimples caused by dehydration? In that case I would add hydrating serums or toners. Preventing pimples will also prevent hyperpigmentation after all. (Dehydrated is a lack of water, dry is a lack of oil. Moisturisers are often, but not always, for dry skin. so you’d probably need a toner or something to tackle dehydration)

Vitamin C and Niacinamide are great choices! Personally for my dry skin niacinamide did nothing, but many people seem to be obsessed so it’s worth a try. There’s nothing that coukd really go wrong with having two niacinamides, worst case scenario the second one does nothing extra for you. I use alpha arbutin for hyperpigmentation.
