Something else Im pretty curious about is that, even with the very noticeable increase in inflammation from the sun burn, my lip hasnt shown any sign of buildup whatsoever. Which I find interesting, because the part that got burned looks as inflammed as it was when I used to get buildup. Its also quite relieving for me as I have always been somewhat worried that its possible that the buildup could come back if the inflammation doesnt go away completely.
Also I have thought all along that I needed to keep a barrier on my inflamed lips to keep them covered from the air. But I have been using just Biafine on my lips for the past few days and have had no buildup. And Biafine doesnt barrier my lips, just kind of moisturize them, because it really absorbs into my lips.
So now Im wondering whether its more about keeping them moisturized rather than keeping a barrier on them.
