Works rather well [SEP] I satrted using this prep because I take a medication that makes me sweat a ton.  Like my make up can be gone 30 minutes after application if the temperature isn't perfect.  I find that this does help somewhat to keep me from sweating so bad.  I would give it another star if it was in a must bottle.  It would make it much easier to apply.  I ended up putti g it in an empty face setting spray bottle.
