I have a strong preference for phlojel but the compounding instructions always throw every one off and get them all weirded out about it.
Penetrate from the board sponser works fairly well and is VERY CHEAP (I'm using it now) . Because it has so much alchohol in it, it will readily absorb base powders without too much difficulties.
Because it is alcohol based it also has a tendency to dry out the skin, which becomes a absorbtion issue.
There is also finaderm from the board sponser Universal Kits. Alot of people love it, but it aint going to deliver the 75% absorbtion rate is promises.
