Some tips use pure aloe just cut a leaf in half cling wrap and keep in the fridge ( aloe is toxic to animals so if you have pets ensure they don't rub on it) moo goo still my fav products they are trying to clean out chance of reoccurance - we are all different so I've found peace in simple things hugs
