In many areas of the country, January is brutally cold. Plus, the dry, warm air inside your house can make your skin feel like sandpaper. Especially if you're a postmenopausal woman. That's because as you enter your golden years, your hormone levels drop off dramatically. As a result, you've got less natural oil and moisture in your skin and hair.

To boost your flagging hormones and improve dry, rough skin, I recommend you give natural progesterone cream a try. It's free from side effects (as long as you don't use so much that you cause your period to start again)...and has lots of benefits. Most women start to notice a difference in just weeks. Your skin will hold moisture better. And it will appear more youthful.

Natural progesterone cream can be a bit tough to find. So look closely at the labels. Most good health food stores carry it as Mexican yam cream.

But remember, progesterone cream isn't like normal skin cream that you apply to dry patches on your elbows and feet. It's a natural hormone that gets absorbed into your system. And it works from the inside out to boost your hormone levels and improve the overall feel of your skin. You'll want to use a touch of it (roughly ¼ to ½ teaspoonful) twice a day on a soft area of your skin (such as your face, inner arms, belly, or neck), as these tender spots absorb the hormone better. Apply the cream in one spot for three weeks. Then move on to a different area.

Side effects from the cream are rare and usually associated with prescription progesterone, called progestin. It's a synthetic knock-off of the real stuff. Make sure you find natural (or bioidentical) cream. In a few weeks, I think you'll start to notice a big difference in the feel of your skin and hair. Even in the coldest of winters!
