The only thing that I can think of is in fact Magnesium Chloride
I used to take in in gel format- on my arms etc..left a sticky sort of glue ad after 20 mins went into the skin but had some flaky film residue on it;also the skin would be wrinkled to a degree(like spending too much time in water)
I solved this by taking Magnesium hexahydrate-(in form of a spray)it goes into the skin within 10-20 secs and zero residue,stickiness gone in less than 1 min or so,skin is not wrinkled anymore,...
You do feel a boost of energy within minutes of taking it
Notes:1-Many companies either get their Magnesium from bottom of the Pacific Ocean (large of Hawaii,Japan,etc..) or from a salt deposit under the sea waterbedwat from the Netherlands coast.
The magnesium hexahydrate(see link below)- comes from the Dead Sea in Israel and it is filtered and ultra pure..
