How often do you use a sleeping mask?

So I've been using a sleeping mask after a moisturiser every night for quite some time :') I felt fine because my skin is really dry and dehydrated so I thought it could use the extra hydration but I just googled and realised that it's actually recommended to only be used once or twice a week?? If you use a sleeping mask, which one do you use and how often do you use it? 😅 Also, do you use a moisturiser before that or do you skip it? I've been using this one by Innisfree every night but now I'm wondering if that's why my blemishes have not completely gone? Maybe because applying a thick sleeping mask every night didn't allow my skin to breathe?
