It looks like penetrate dried my skin completley. from the looks of it some of the PH is not getting in as there is white dried powder where the skin in dry, this is in line with transdermal science - no water=no penetration. other places where not dry - no problems.
problem is I rather put on my knees (where the skin has dried) and not on arms/sholders, cause of my girlfriend touching arms and shoulders, and my knees deserving the 19-nor .
any solution? should I use some moisturizing cream before or after? should I add some moisturizing agent or aloe to penetrate?
