Mandelic Acid Deodorant: The Secret to Brighter, Fresher Pits?
by Truly Beauty

If you want a deodorant that lasts all day, mandelic acid deodorant might just be your best option. With antibacterial and exfoliating properties, mandelic acid deodorant is an effective option for controlling body odor while tackling underarm dark spots and discoloration. 

Thinking of making the switch to a deodorant with mandelic acid? Here is everything you need to know about mandelic acid in deodorant and why you need it. 

What is Mandelic Acid Deodorant?

Mandelic acid is an alpha hydroxy acid (AHA) derived from bitter almonds. It’s an exfoliant that removes dead skin cells, brightens skin, and fades hyperpigmentation, while neutralizing odors. 

Mandelic acid is oil-soluble, which means it penetrates deeper into skin to unclog pores and has been shown to reduce excess sebum production. It also has a larger molecular weight than other AHAs, meaning it penetrates the skin slowly and is ultimately gentler and less likely to cause irritation.

Mandelic acid deodorant doubles up on the regular deodorant duties. It gently exfoliates to keep hair follicles clean and odors away. And it speeds up cell turnover to fade dark spots and discoloration. Unlike traditional deodorants, mandelic acid deodorant doesn’t mask body odor. Instead, it targets the root cause of odor for better results. 

Benefits of Mandelic Acid Deodorant

Is mandelic acid good for body odor? Can I use mandelic acid on my armpits? Yes, and yes. There are a myriad of mandelic acid deodorant benefits. Here’s what it can do.

Controls Body Odor

Mandelic acid deodorants are antibacterial. By preventing bacterial growth, which causes body odor, mandelic acid deodorant keeps the underarm area smelling fresh for hours. At the same time, its exfoliating properties stop odors from getting trapped in dead cells, which can contribute to unpleasant smells.

Brightens Dark Underarms

Mandelic acid deodorant exfoliates and increases skin cell turnover, helping to push fresh skin cells up to the surface which can reduce hyperpigmentation. Whether you’re dealing with dark spots or patches on your armpits, mandelic acid as a deodorant can help with regular use. Even studies show it can be effective for treating hyperpigmentation.

Prevents Ingrown Hairs

Some people use mandelic acid deodorant after shaving to prevent ingrown hairs. By keeping the hair follicles clean and with its antibacterial activity, this AHA stops ingrowns from forming and existing ones from getting infected.

Ensures Long-Lasting Freshness 

Unlike traditional deodorants that typically mask odor, mandelic acid deodorant targets the root cause of body odor by reducing bacteria on the skin. In doing so, it provides day-long protection against body odor to keep you smelling fresh for hours.

How Does Mandelic Acid Stop Odor?

The main cause of odor in the underarm area is bacteria. Mandelic acid deodorant specifically targets the bacteria that causes body odor. These bacteria thrive on an alkaline pH. Mandelic acid deodorant lowers the skin’s pH to a more acidic level, stopping body odor at the source.

Its exfoliating action also helps. By removing the buildup of dead skin cells, mandelic acid deodorant alleviates odor-causing bacteria that leads to unpleasant smells. Plus, it speeds up cellular turnover to keep the hair follicles clean and odors away. 

Is Mandelic Acid Safe in Deodorant?

Before you make the switch, you might be wondering is mandelic acid deodorant safe? It is safe. Just as you would apply it to your face in the form of serums and other skincare products, mandelic acid deodorant is safe to use on the underarms as well as other areas of the body prone to odors like the feet. 

Mandelic acid deodorant is gentler than other AHA formulas, so it’s much less likely to cause irritation or inflammation on the underarm skin. With its large molecular weight and anti-inflammatory activity, mandelic acid in deodorant penetrates the skin slowly and gently without causing irritation. 

That being said, it is always a good idea to monitor how your skin behaves when you use a mandelic acid deodorant—just like you would with any other new product. If your skin reacts negatively, you may need to reduce the frequency of use or refrain from using altogether. However, it’s unlikely that you’d experience any negative side effects of mandelic acid deodorant. 

Is Mandelic Acid a Good Deodorant? 

Mandelic acid deodorant is a great option for anyone looking for long-lasting freshness. Because this AHA targets body odor at the source by lowering skin’s pH level and eliminating bacteria, it can be highly effective at keeping odors at bay.

But its benefits don’t stop there. Mandelic acid deodorant exfoliates and increases cell turnover while regulating melanin production to both treat and prevent underarm discoloration. It keeps the armpits bright and promotes a more even skin tone, making it the perfect choice for those dealing with hyperpigmentation.
