I had no idea that a bar of clay could be a panacea to so many different skin ailments, but Fresh's Umbrian Clay Treatment Bar ($38) does the job. Umbria is a clay-rich region in Italy, and the treatment bar is made from pure clay. It has the appearance of soap, but once you feel it, you'll see that it's chalky, hard and much heavier and more fragile than soap.
It helps with breakouts, diaper rash, mosquito bites, razor-burn, ingrown hairs and eczema. It works by regulating the production of sebum in your skin, reducing inflammation, and balancing out your skin's natural acid level. I couldn't believe that after just one use the tiny bumps on the back of my arm (that I sometimes get in the hot summer months) dried up and flattened. After two uses, they almost completely went away.
To use, wet an area of the bar and apply it directly to your skin. It dries to a thin finish and is very gentle so it can be used on the most sensitive skin, even baby skin. You can use it as a mask (leave it on for five minutes and rinse) or as a spot treatment.
