When I was a CNA my hands were REALLY BAD. To make a long story short, my microbiology teacher at the time, told me to make sure to rise my hands of the soap REALLY well. Turns our that was part of my problem. I noticed that my hands became better after i made a conscious decision to rinse them longer than what I was previously doing.
I also have to give my hands a little TLC every now and then too. To do so, I take one part sugar with one part olive oil, mix together in a dish, and then scrub and rinse my hands. Olive oil is great for the skin and the sugar scrubs
the dry stuff off (makes your hands soooo soft). Afterwards, I apply Avons moisture therapy lotion (i think thats what it is called), wait for it to dry, and then apply Avons silicone glove lotion. Love the silicone glove lotion because it helps protect your hands when you wash them. Sleeping with petroleum jelly and gloves (the ones you can find in the beauty isle) works well too.
Best wishes to you and your lil hands!!
