The heat and humidity are bad but over the next few weeks you are likely to suffer even more. The “polar invasion” may cool off some parts of the country for a few days, but then the hot weather will be back for the rest of July and most of August. Are you prepared?

Most people grab an antiperspirant without bothering to read the label. Every single such product on pharmacy shelves has aluminum salts as the primary ingredient. For some, aluminum is irritating. For others, the aluminum-containing ingredients leave a yellow stain on white shirts after washing.

What about aluminum absorption into the body? There is quite a controversy about whether aluminum applied to the underarms is absorbed systemically. Given that hundreds of millions of people around the world apply aluminum-containing antiperspirants to their delicate underarm tissue every day, you might think that elegant scientific studies would have been conducted to determine the extent of aluminum absorption.  You would be wrong. A study published in the Journal of Inorganic Biochemistry in May, 2012 noted:

 “Aluminum salts such as aluminum chlorohydrate (ACH) are known for use as an active antiperspirant agent that blocks the secretion of sweat. A local case report of hyperaluminemia in a woman using an aluminum-containing antiperspirant for 4 years raises the problem of transdermal absorption of aluminum (Al). Only a very limited number of studies have shown that the skin is an effective barrier to transdermal uptake of Al.”

Because women often apply antiperspirant to underarms after shaving, the barrier function of the skin may be compromised. How much aluminum is absorbed every day from underarms remains a mystery. And if the aluminum accumulates in the body, there is also controversy about the risk. Some experts in the U.S. maintain that worries about aluminum are overblown. Others, especially from France and England, have a different perspective. Toxicologists from France and Switzerland offered this perspective in the Journal of Trace Elements in Medicine and Biology (April, 2014):

“Since aluminium (Al) pervades our environment, the scientific community has for many years raised concerns regarding its safety in humans. Al is present in numerous cosmetics such as antiperspirants, lipsticks and sunscreens. Al chlorohydrate is the active antiperspirant agent in underarm cosmetics and may constitute for Al a key exposure route to the human body and a potential source of damage. An in vitro study has demonstrated that Al from antiperspirant can be absorbed through viable human stripped skin. The potential toxicity of Al has been clearly shown and recent works convincingly argue that Al could be involved in cancerogenic processes…As a consequence, given that the toxicity of Al has been widely recognized and that it is not a physiological component in human tissues, reducing the concentration of this metal in antiperspirants is a matter of urgency.”

Lacking definitive research proving the safety of chronic aluminum exposure from antiperspirants, we are erring on the side of caution. That is why we created aluminum-free MoM (milk of magnesia) underarm deodorant. It’s gentle and won’t stain shirts.

We are extending our special sale till the end of July for The People’s Pharmacy Aluminum-Free Roll-On Deodorant. If you put our MOM20 code into the discount code box on checkout you will have 20% knocked off the price. Stock up now for the hot humid weather ahead.

Here are some reports from visitors to our website:

“MoM Deodorant is the best thing ever! I was skeptical before I tried it but it really does work. I still sweat on hot days but the odor is gone.

“There’s one other thing I do daily that helps, especially on hot summer days: after I shower I swab my underarms with the original gold Listerine to kill the bacteria, then I use the lightly scented Women’s MoM Deodorant.” Elizabeth

” I have used milk of magnesia for about 18 years with great results.

“The way I use it is diluting it with water at 50% then pouring 2 to 3 ml in to the bottle cup to apply it under my arm. Works great. It was recommended by my dermatologist in 1995.” Joaquin

“I have always had a problem with underarm odor. Everything I tried caused an underarm rash. When I tried this new product (milk of magnesia) roll on, it did the trick without any problem.” Ron

Let us know how milk of magnesia works for you. And don’t forget to take advantage of our 20% sale with the discount code MOM20 when you check out. This sale will last through the end of July, 2014.

    Thanks to Peoples Pharmacy I have been applying MOM for about six months with excellent results. I just dabbed it straight from the bottle.

  2. Tony

    I have been using mom straight out of the bottle. I apply it using a gauze pad. This has worked great for the past 4 years. I purchase the store brand since it is the least expensive

  3. Eileen

    I’ve been using MOM deodorant for the past couple months now and I find that it does work well in preventing sweating, but on the hottest days, I do detect odor on my clothing. I’ll occasionally use my old antiperspirant if going to a special event, but otherwise, I prefer to stick to the safer alternative. I’m so glad I discovered MOM deodorant.

    Try slicing a fresh lime in half and using that — very effective long-lasting anti-deoderant. Don’t use lime juice, use a lime. Also slows reduces actual sweating. oranges and grapefruits don’t hack it, only limes — no idea why.

  5. JB

    MOM is a deodorant. Is there anything safe in anti-perspirants?

  6. Rick M.

    I use milk of magnesia straight out of the bottle under my arms and it works great. It dries clear in a short time. The only commercial product I have tried that does not give me underarm itch is the Arm and Hammer brand solid based on baking soda and I use that when I travel. Some of the airport x-rays don’t like a bottle of milk of magnesia.

  7. Len A.

    Found MoM unflavored works best. The stuff from the Dollar Stores seems most effective. Less “refined?”
