Alcohol vinegar is I think sometimes referred to as "white vinegar". It's usually just aceitic acid diluted with water.
I wear lace.. With this photo I wanted to show how well the lace sits in the glue and how non-shiny it is.
The line that looks like excess skin of a skin system is where the glue starts ( I mentioned I always apply the glue a few millimeters below where the hairline(hairsystem) starts... if for some reason the line would lift, I can just tear the lifted part off and don't have to do touch ups.
