Are these waterproof? So if it is on your finger, and you wash your face with your hands, does the bandage come off or does it survive?

Very much so. I've been using these to heal road rash (and similar injuries for 15+ years) and they will survive 2-3 hot shower/bath cycles. DO NOT use lotions, moisturizers nor oils near the edges of this type of bandage. Failures occur most often due to (from most often to least): () sharp corners - they start peeling off easily with any friction like normal clothing or bed fabric. SOLUTION: cut broad round corners. () skin oil - it is ABSOLUTELY imperative that the skin is as oil/grease free as possible. Rubbing alcohol is the best way to go EVEN IF you only use it on the skin adjacent to the injury. In the decade plus of using these this is the way these fail most often for me because during exercise my extra greasy skin is too much for the DuoDerm. If I'm having a lazy week I have got them to stay on 6-7 days. () excess internal liquid (the icky failure mode) - when the wound has produced so much liquid that it has leaked out the edge the bandage is no longer sterile. It needs to be replaced.

Does this have the gel inside?

Yes the gel is inside each one. I found it very effective. I changed it more frequently then they suggested, and the healing time seemed very acceptable

Is this product latex free?

Yes, it’s says so in the description.

Are these the clear patches?

How about saying that they aren’t transparent instead of right-fighting. They don’t match every skin tone, even amongst Caucasians. I wouldn’t say yellow either.
