I just received a tub of MdC Chamomile and have to say it's fantastic. However, it seems as though any time it gets above 72-72F in the bathroom it turns to liquid. Seems to still work ok but I think I prefer applying it when it's semisolid. Is this normal? Any way to prevent this other than keeping it in the fridge? Does this harm the product at all liquefying and solidifying what seems like every 2 hours?
