Mineral-rich Epsom salt can soften dry, rough skin by hydrating and moisturizing it. The compound can even calm serious dermatologic conditions like psoriasis or eczema. And on a more superficial level, it may diminish the appearance of wrinkles.
For an ideal moisturizing effect, use warm (not hot) water when soaking or cleansing with Epsom salt. Also limit your time in the water. For optimal results, apply a moisturizer within three minutes following your Epsom salt bath or wash. This will help lock in moisture.
Epsom salt is also a wonderful exfoliant. Mix it with petroleum jelly to scrub rough skin. Just be sure not to use petroleum jelly on your face, as it can lead to a breakout.
