Should You Be Using a Laxative...on Your Skin?





here are a handful of unique "miracle" skin treatments available in medispas and as DIY options: sheep placenta, urine, blood—these are just a few of the more PG-rated ingredients. Just do a quick search and you'll see what I am talking about.
I am generally open to exploring the scientific legitimacy behindunusual options, and that is exactly what I did when it came to a relatively recent fad: the milk of magnesia (MOM) facial. MOM is indicated for use as a laxative/antacid combo. And it is touted by some online beauty pundits as a good primer option for those with oily, acne-prone skin. I tend to disagree. Not with the fact that it may be an effective degreaser, as it may be, but rather with the idea that it would benefit the skin.
After taking one look at the ingredients, I would not condone its use in a dermatologic context. MOM's active ingredient is magnesium hydroxide (the theoretical lipid buster) plus it also contains sodium hypochlorite (bleach), and it has an overall pH of 10.5. Our skin and its protective barrier, the acid mantle, operate best at a slightly acidic pH of 5.5. Anything that increases the pH to the basic end of the spectrum (e.g., soap, harsh astringents, and MOM) disrupts the natural equilibrium of our largest organ, potentially leading to irritation. (See: What Might Be Causing Your Acne to Flare Up.)

While it makes sense that something basic (that is, having a high pH) is beneficial in neutralizing the harsh acidic environment of the stomach, it does not operate the same way in keeping the biological milieux of our skin intact. Now, that being said, one application of MOM to an acne-prone complexion wouldn't necessarily wreak total havoc—although it may. And long-term use could certainly strip the barrier of essential lipids and proteins that lock good in and keep bad out. It boils down to this: Why risk it when there are so many healthier and safer options?

is coffee ok when you are pregnant???

Caféine during pregnancy Now that I'm pregnant, do I have to stop drinking coffee and avoid other sources of caffeine? If you're pregnant, it's a good idea to limit your intake of caffeine. But how much is okay? After decades of discussion and conflicting studies, there's still no clear answer on how much caffeine is safe during pregnancy. To err on the side of caution, the American College of Obstetricians and Gynecologists (ACOG) advises pregnant women to limit their caffeine intake to less than 200 milligrams per day, which is about one 11-ounce cup of coffee (See the chart below to get a sense of the amount of caffeine in common beverages and foods.) What are the concerns about caffeine consumption during pregnancy? When you drink a cup of coffee, caffeine crosses the placenta into the amniotic fluid and your baby's bloodstream. While your body goes to work metabolizing and getting rid of the caffeine, your baby's body is still developi

How to Make Eyebrows Grow

How to Make Eyebrows Grow If you've accidentally over plucked your eyebrows, you're probably ready for them to grow back as soon as possible. While there's no magic trick to making your eyebrows grow back in, there are ways to make the transition a little easier. A well-utilized eyebrow pencil may keep anyone from noticing! Method 1  Waiting it Out 1)    Plan to wait for several months. Eyebrows take a long time to grow back fully after they've been overplucked. For some people it might only take six weeks, but others may have to wait a full year before their eyebrows regain their former shape. The best thing you can do for your brows is to be patient. Look at it this way: at least your brows won't need a lot of maintenance for a while. 2)Stop plucking and waxing. You probably already know this one, but it's worth emphasizing that plucking or waxing around your eyebrows isn't going to help them grow faster. In fact, some

I Gave Up Coffee—Here’s What Happened to My Skin

If you’ve ever seen a dermatologist for acne, rosacea, or any kind of inflammation, really, I bet you’ve heard this advice before: Stop drinking coffee. I’ve encountered those words many times, but never acted on them. Until recently that is, when my curiosity (and quest for better skin) finally overtook my caffeine addiction. I went coffee-free for three weeks and lived to tell the tale with some surprising results. Keep reading to find out what happened! Why Coffee? You always hear people swear that giving up , changed  everything  for their skin. Most often, it’s  dairy ,  sugar , wheat, or coffee. With countless dermatologists telling me that cutting coffee is what would finally take care of my pesky breakouts, I retired my Starbucks card in the name of better skin. Why is coffee the culprit? Long, scientific story short: It’s because coffee is highly acidic. High doses of acidic caffeine mess with your hormones, namely your stress hormones, which control your skin’
