I was under the impression that wearing a silicone mask over face masks would let me do other things whilst I wait for the mask essence to be absorbed. This silicone cover just squeezes the essence away from my cheeks and nose so it just ends up being pooled around my forehead, chin and neck instead. It also hurts behind my ears if I leave it on for longer than 30 minutes. So far, I have only found it useful when wanting to use a sheet mask whilst also having a shower.
