Part 1: What is Glycolic Acid?

Glycolic acid belongs to the class of alpha-hydroxy acids. It is obtained from sugarcane. Due to its low molecular weight, it can seep deeper into the skin and be more effective than other products.
It is a chemical exfoliant that sloughs off the dead skin cells from your skin’s surface and gives it a smooth appearance. Let’s discuss its benefits in the next section.
Part 2: Is Glycolic Acid Good for Armpits?

What does glycolic acid do for armpits? This one ingredient can address many issues of the delicate armpit skin. Let’s see how!
Glycolic acid is known for its ability to enhance skin texture, making it suitable for sensitive areas like the armpits.
Benefits
- Glycolic acid can act as a deodorant for your underarms. It has a lower pH as compared to the skin therefore it can kill the bacteria that cause odor in your armpits
- Dark underarms are common, making it embarrassing for women to wear sleeveless dresses. This alpha hydroxy acid can help treat hyperpigmentation
- Since glycolic acid also has exfoliating properties, therefore using it after underarm hair removal can help prevent ingrown hairs
- It increases cell turnover and helps in achieving a brighter skin complexion in the armpit area
This natural acid can effectively combat odor-causing bacteria, providing a fresher feeling throughout the day.
Using glycolic acid may help lighten dark patches, boosting confidence in wearing sleeveless attire.
It can also aid in minimizing the risk of ingrown hairs, making post-hair removal care easier and more effective.
With consistent use, glycolic acid can contribute to a more radiant appearance in the armpit area.
Side Effects
Although glycolic acid comes with numerous benefits for the armpits, it also has some side effects:
It is essential to be aware of these side effects to minimize discomfort and maintain healthy skin.
- Misuse of glycolic acid on the sensitive underarm skin can cause redness, inflammation, erythema, and irritation
- It cannot be used in combination with retinol as these two can irritate the skin causing darkening of the irritated area
- Since the underarm skin constantly rubs against your torso therefore it can cause skin sensitivity
Redness and inflammation can be particularly concerning, especially for those with sensitive skin.
Avoiding combination use with retinol is crucial to prevent further skin irritation.
Skin sensitivity can exacerbate discomfort, making proper application techniques important.
Expert Opinions
Is there any research regarding the use of glycolic acid for armpits? In 2021, research was conducted on the effect of glycolic and phytic acid complexes on hyperpigmentation. A significant improvement was observed after 4 and 12 weeks of use.
In addition, Dr. Garshick told TODAY that when glycolic acid comes in contact with the skin, it reduces the pH making it difficult for bacteria to survive in such an environment. Hence, odor-causing bacteria are reduced.
Dr. Garshick's insights highlight the dual benefits of glycolic acid in skincare routines.
However, doctors still recommend people to use glycolic acid for underarms carefully. Dr. Verma stated in REFINERY29 that it might be a bit risky to use if you have oversensitive skin. In addition, if you are using it for more than the recommended time, it can disrupt the skin barrier.

Step-by-Step Instructions to Use Glycolic Acid
- First, you need to get your hands on the right product. Since the underarm skin is delicate, a product with less than 10% glycolic acid can be safer to use

- Then soak a cotton pad in the product and apply it gently on your armpits
- Once it is completely absorbed into the skin, you can apply a gentle moisturizer to reduce the friction and prevent glycolic acid side effects
Choosing the right product is vital for achieving the desired results without risking irritation.
Proper cleansing lays the groundwork for effective application and can enhance results.
Gentle application is key to ensuring that the glycolic acid works effectively while minimizing potential irritation.
Applying a gentle moisturizer after glycolic acid can significantly help in reducing any potential irritation and maintaining skin hydration.

Patch Test for Glycolic Acid
To ensure that you are using glycolic acid the right way, you must ensure the following:
- Read the ingredients of the product you are buying carefully. It must not contain more than 10% of the glycolic acid
- Before applying the product to the armpits, conduct a patch test. Choose a small area like your inner forearm and apply a little product there
- Since it takes time to absorb into the skin, wait for a few hours to confirm that your skin does not react to the product
- If you see any irritation, you can either try a product with a lower concentration or one mixed with natural ingredients to provide a soothing effect to your skin
It's important to choose products with careful consideration of their glycolic acid concentration, as higher levels may lead to skin sensitivity.
Conducting a patch test is crucial to ensure skin compatibility and to avoid any adverse reactions before applying the product to larger areas.
Waiting a few hours after application allows you to assess your skin's reaction, which is essential for safe usage of glycolic acid products.
If irritation occurs, opting for products with lower concentrations or those enriched with soothing natural ingredients can help alleviate discomfort.
Part 4: How Often to Use Glycolic Acid on Armpits?

Using glycolic acid daily on the skin can irritate it and cause sensitivity therefore it is recommended to use it only one to two times per week. Initially, you can start with once per week to let your skin get used to the product.
Then, you can increase the application up to three times depending upon how your skin reacts to glycolic acid. However, if you have sensitive skin then you can keep it only once per week. Also, maintain a consistent routine for using it for the long term and see more effective results. Keep a check on changes in your skin appearance. If you see any side effects, you can either get a consultation from a dermatologist or replace it with other products.
Moreover, using it for a long time can increase skin sensitivity so do not forget to wear sunscreen on your armpits if you are wearing a sleeveless dress to protect them from the sun.
Wearing sunscreen on your armpits is crucial, especially when exposed to sunlight, to minimize the risk of skin damage.
Conclusion
Glycolic acid can be used to exfoliate dead skin cells, treat hyperpigmentation, brighten the underarm complexion, and prevent ingrown hair. It cannot replace a deodorant or an antiperspirant but can help reduce armpit odor by preventing bacterial growth.
Glycolic acid is often favored for its ability to enhance skin texture and brightness, but it should complement, not replace, traditional deodorants.
However, underarm skin is very delicate therefore we must be careful while using glycolic acid for the armpits. Do not exceed the safe amount and avoid using it daily otherwise, it can cause redness, flakiness, and skin sensitivity.
Due to the sensitivity of underarm skin, it is essential to monitor usage of glycolic acid to avoid adverse effects like irritation.
