When I first moved over to Melbourne I basically got hives and it has been coming and going. So I went into Aesop (which is from here so it's cheaper, wahoo!) and asked for some recommendations. The guy in the store recommended the Aesop Chamomile Concentrate Anti-Blemish Masque to help calm the situation down. It's full of lovely oils and smells really herby. I do find that this helps makes my skin chill the f out when it's looking pretty angry and it also makes me skin feel less itchy.
Another favourite (I'm trying to spell like a British person again!) is the SkinCeuticals C E Ferulic (Combination antioxidant treatment containing l-ascorbic acid, alpha tocopherol, and ferulic acid) - I have no idea what any of this means by the way but maybe you do? It's an orange liquid that dispensed through a little pipette and on the back it says it 'Combines proven antioxidant vitamins C+E with ferulic acid to maximize antioxidant performance. This synergistic formulation enhances protection against damaging UVA/UVB rays to better prevent premature signs of aging, while simulating collagen production to help diminish the appearance of photodamage.' All I can say is that I like to apply it in the morning before my SPF because it makes my face feel a hell of a lot smoother. But I'm warning you, it's pricey...
If my skin is a bit dry I wear the Vichy Normaderm Daily Anti-Acne Hydrating Lotion which contains salicylic acid. If you have acne prone skin this is pretty good because it hydrates your skin without being too heavy or clogging up your pores. And salicylic acid is supposed to be good for blemishes.
The last product is the SkinCeuticals Retinol 0.5 which is a cream you can use by itself as a night cream or mixed in with your usual night cream. I swear by retinol when my skin is really congested and it is supposed to help combat signs of aging so it's a win win product. Some people find that retinol is too strong for their skin so you can use creams with a lower strength of retinol in it and then build it up as your skin becomes more tolerant.
I hope this is helpful if you're having hormonal acne/similar sensitive skin issues!
