What is good for treating freckles and blemishes?

When I look in the mirror, I notice that at some point, I started seeing small blemishes, like freckles, around my eyes and cheekbones. Now that I’ve noticed them, they keep bothering me, so it’s starting to get a bit stressful.

I asked my friends, and they told me that I should start taking care of my skincare routine properly by applying toner and lotion, and that sunscreen is absolutely essential. So, I'm thinking of completely changing my basic skincare line. Are there any products suitable for men that aren't too greasy and help with freckles and blemishes?

Right now, my face feels a bit tight after just washing it, so I want something that provides solid hydration, but I don't like things that are too sticky, so it's hard to choose. Should I add a vitamin serum, or would a single functional lotion be enough?
