"Few would think to form rhymes with the terms collagen, melanocytes, and sweat glands, but Dr. Joanne Settel, aka Dr. Jo, gives the skin-ny on humans’ largest organ through a series of amusing yet highly informative rhymes. Starting with skin basics, such as its purpose, make up, and many layers, she continues with shades of skin, including blushing, tanning, and freckles, and how skin changes, from raising goose bumps to wrinkling when wet to getting downright sweaty... Squiggly, cartoonlike illustrations highlight the humor and depict occasional skin diagrams. Children will pore over this inviting look at their skin."
