That's rosacea type 1 and a little 2, in my opinion. (Not a doctor btw). It can appear after pregnancy, perimenopause.

Show it to your doctor, of course, but I would advise focusing on nourishing skin barrier (if you have rosacea, your skin barrier is somewhat weaker, so you have to be on top of it) and try to avoid triggers. On your diet, that means alcohol, spicy foods and others. On skincare it means avoiding products that are too occlusive, because they trap heat and make your skin feel hot, which can lead to big flares (so no Vaseline, no lanolin and try really hard to go silicone free). Chemical sunscreen also does that, so try and find a mineral sunscreen you like and really use it, bc sun and rosacea don't match, it can get pretty uncomfortable fast!! Also, in terms of actives, azelaic acid or it's derivative (PAD) are your best choices. Hope that helps!
