It depends, a lot of people are going hard in on skincare and want their makeup to look like "real" skin, so use a lighter foundation or BB cream with maybe a little concealer.
I used to hate my freckles so always wore a very full coverage foundation but now use Trinny BFF which just sort of evens out my skin tone and add a shit ton of concealer under my eyes as they are black and purple.
I was also pushed into this as I have vitiligo on my face and mixed with the freckles the heavier foundation just went orange in the white areas and looked odd. Took a bit of adjustment but I'm used to it now, and a heavier makeup feels odd and settles in my many expression lines in my forehead lol.
I use a lot of blusher, not all at once but it's my favourite makeup product. I like to do it quite high and I to my temple at the minute, it's quite lifting.
I like to do a good eye look if I have time, but always wear some sort of eyeshadow. I line my upper lids and tightline the upper lash line.
I dont do the lower inner rim as I think it does look dated, but I will smoke out some eyeshadow below the eye.
I'm 41 for reference, but do what you like to do, there's enough makeup looks around for everyone. Take a bit of this and a bit of that and see what you enjoy. Just remember ALL (OK 99.999999%) makeup tutorials on the Internet have filters on them, real skin has pores, real people haven't time to put lashes on off camera.
If you aren't happy with your makeup have a play about and change it. If you are happy then keep on being fabulous
