I bought this mask due to its claims to repair moisturiser as my tretinoin dosage has been increased and my skin is really feeling it.. I like that the mask comes in two parts: one for upper and one for lower which allowed for a better fit on the face. My only complaint with this mask was that it stung my skin for the first 5 mins it was on my face, but that’s probably due to my compromised moisture barrier. But after wearing the mask and layering with a thick emollient moisturiser, my skin was soothed and felt amazing. Just be aware that if your moisture barrier is compromised, this will sting.
