Hi Nash,
Your information is great. Future members will benefit a lot from this. I was also fortunate that I was given Carac. There are many people posting what they've learned, tricks of the trade, so here's mine. I'm on application 22 for Facial area.
Plan ahead - Carac being used only once a day is usually at bedtime. I apply it about 7 p.m. so if the need comes for another cream (for me it hasn't) then the alloted time would pass before my usual 10 p.m. bedtime.
Daily prep - I wash and air dry (no towel) for 20 minutes before applying Carac. Don't scrub the area with a cloth, use your hands, or you'll get RAW fast.
Drink plenty of water along with juices, to stay hydrated, heated/conditioned air in buildings dry your skin out.
Applying to sore spots - use your ring finger. It has the least strength so you won't rub it in too hard and cause more pain. Tapping it on lightly at extra senitive areas. Wash hands and under nails thoroughly when done.
Itching - use your fingernail and lightly poke the area and the itch goes away.
