TBH IDK because I put this on my pimple and I swear it just made it more prominent and redder. Wouldn't repurchase
These are effective and I definitely like how they stick onto the skin well. They really don't budge like some other patches do
I got these for my sister and she loves them. It helps with the healing process and helps prevent scars. Also prevents dirt from getting on the "open wound".
The patches are effective but not really "magical".
