I'm gonna do it all over again early next week but this time gonna be strict with it and try to leave the product on for as long as possible until it comes off naturally. I'm thinking maybe a month or 2 having this barrier on should be enough time to fully heal my lips.
I agree with you about the 4 hours being not enough. Usually I would apply one coat & then another one after 30 mins until I can actually feel there's something on my lips. After 2 days the barrier becomes much more noticeable (to me), so this time I know there's a barrier on my lips & I don't have to keep making sure.
About brushing the product off, I've tried to do that but it just slows down the progress and the newly formed skin dies even after I immediately apply the product. If you can leave the barrier on all the time then the healing will take place 10 times faster.
If you're mostly at home during the day, then this is the perfect opportunity for anyone to heal their lips.
Another point is, don't stretch your lips too much by smiling or you will tear the barrier. After a few days it becomes harder to freely move your lips. Remember the barrier has to cover your lips at all times to protect & moisturize the skin underneath so that healing takes place.
Nobody will notice there's something on your lips unless you tell them. It will look like you have chapped lips or very dry lips but the barrier remains invisible.
