Steroid creams should only be used for about 10-14 days at a time as they can cause redness if used for extended periods of time. You should check with your doctor - sometimes you can use a Vitamin C serum or other anti-oxidant cream which can work as anti-inflammatory for the skin. After any laser resurfacing you want to make sure you also keep it very moist.
Looking at the photo which shows your fair skin, I am thinking that you may be experiencing a small rosacea flare-up after your laser treatment. This makes sense because you have had the reaction before. I would not recommend relying on steroid for this because it can cause rebound redness and inflammation when stopped or acne and other side effects if overused. Instead I would only use gentle anti-inflammatories like creams, gels or serums with aloe vera, cucumber or bromelain. We like SkinMedica redness relief or SkinCeuticals Phytocorrective gel In the U.S. we have a nice new gel called Mirvaso which is essentially the medicine in Afrin spray which helps calm redness temporarily in rosacea-prone skin. In addition, you can just go with a bland moisturizing cream like Cetaphil and a non-irritating sunblock with no chemical sunscreens (just zinc oxide and titanium dioxide)
