Help for my pregnant wife

Hello,

Looking for some remedies or advice to help my wife go through a bad flare up on her face and neck. I tried looking online but a lot of it is steroid cream. She had mentioned before in the past that it’s not good to use it on her face as it’ll thin out your skin.

Long story short, 2 years ago we had our first kid and her psoriasis flared up on her face and neck. Now she’s 21 weeks pregnant and it started to flare up a couple days ago on her face and neck again. Way earlier than the last time.

If there’s any recommendations for creams or anything else would be much appreciated. We are located in Canada. Thank you for your time.
