Daily mask packs, are they toxic if used too often?

My skin is so dry these days, so I've been using a sheet mask a day. A friend told me that using a sheet mask every day can weaken the skin barrier. I love the cooling, soothing feeling after applying it, so I can't give it up.

Does anyone here use a daily sheet mask every day of the week? I don't experience any breakouts, but I'm a little worried that the excessive nutrients might actually be toxic. I think it would be fine to just use gentle, moisturizing products. I was also wondering if it would be a good idea to take a few days off after receiving a treatment at Maypure...
