When I first started using it I thought it was increasing buildup the first few days, then when I started using after my lips had prematurely peeled I noticed it was making the buildup slower to appear along with the fucidin.
Each morning I would awake with a little gunk from the products that washed off easily... it was like the buildup but it no longer clung to my lips and make them as sore and inflamed.
Prevex not only helps the buildup from creating,
but when it did it makes it attach to skin less.
I don't think growing big buildup on the lips is good for them.
The goal is not to rub it off, but also to have it come off on its own easier at the same time.
Overtime it just got better and better until everything started healing.
My lips today have no traces at all of the EC I had whatsoever. Healed and gone for a few months now and forever.
