Steroid cream after laser
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.
Redness vs. Rosacea after Laser resurfacing
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)
