Am I applying too much Silagen if it leaves a filmy layer on my skin?

I got cleared to start scare treatment for my anchor scars from a breast lift & augmentation, I have been using Silagen two times a day, but have noticed that it leaves a filmy layer, even after showering, that doesn't come off unless I pick it off. I don't want to pick at anything near that area, so I am just leaving it for now. Does that mean that I am using too much of it, or is this part of the process? Thank you so much!
