help! is this eczema?

hey everyone. i’ve had this rash pop up a while ago and hasn’t really bothered me until now. i’m pretty sure its eczema, im not sure what else it could be. i’ve never had it before and was just wondering what measures i can take to help get rid of it as i’m really worried about it spreading to my face. i’ve just had a 6 month long battle with perioral dermatitis and im super scared if this spreads its going to really affect my mental health like my PD did. Any advice would be reallt appreciated thank you 💖💖
