Can Glycolic Acid Lighten Dark Underarms

Glycolic Acid is an Alpha Hydroxy Acid that works by dissolving the connections between dead skin cells.

  • This aids in resurfacing (or smoothing) the top layer of the skin.
  • This also triggers your skin to make more collagen.

Glycolic Acid doesn’t require abrasive scrubbing like mechanical exfoliants like face scrubs and brushes.

How To Correctly Use Glycolic Acid For Underarms

Remember that because your underarm skin is thinner, rubs together, and is more sensitive, glycolic acid will penetrate more deeply. So, be careful!

The safest glycolic acid concentration for the underarm area is between 8% and 10%. You can also use a lower percentage but it will take longer to work.

It’s recommended especially for those with sensitive skin that they start off with a low concentration.

How to use glycolic acid on your underarms:

  1. Cleanse your skin and pat dry
  2. Conduct your regular underarm skincare routine
  3. Use a small amount of the glycolic acid product (toner, serum, or moisturizer) in the space of the coordinating skincare step in your routine. 
  4. Apply your underarm care products (deodorants and antiperspirants) 
  5. Apply sunscreen

Tips To Follow When Using Glycolic Acid For Armpits

  • Use a low concentration of glycolic acid (the most common one available is 7%).
  • It is also best to use glycolic acid on your underarms in the form of a cleanser, toner, serum or even in a moisturizer or mask. These preparations are usually more gentle on the skin than chemical peels.
  • Just use one product. Using a whole line of glycolic acid-containing skin care products is not necessary. To reap the benefits, just one product is required.
  • Always do a patch test. Choose a small area of skin and try out the product before spreading it on the whole area. See how your skin will tolerate it. 
  • Even though it is your underarm, still use sunscreen as glycolic acid can make your skin more sensitive to sun exposure. 
  • Do not skip the deodorant and antiperspirants.

Can Glycolic Acid Replace Deodorant

Glycolic Acid cannot permanently replace your deodorant. 

A theory rather than a proven fact is that glycolic acid can be used as a deodorant. While it may help to lessen odor, it does not stop you from sweating.

This new take can be credited to the viral TikTok trends we see so often of people replacing their deodorant with glycolic acid. 

However, while glycolic acid has many benefits, it simply cannot replace your deodorant. Here is why:

1- Glycolic Acid does not stop you from sweating under your arms.

It does not contain any ingredients that block your sweat glands. 

While it temporarily lowers your pH and can lessen the buildup of odor-causing bacteria from accumulating, you will still sweat, which will eventually neutralize the glycolic acid. After this, odor-causing bacteria can still accumulate, just not as much.

2- Glycolic Acid Should Not Be Used Everyday

When applied on the armpits too, where the skin is thin and the folds rub against one another, glycolic acid, like other exfoliating acids, can irritate the skin.

This could result in sensitivity, flaking, and redness, especially if used every day.

Risks Of Using Glycolic Acid For Underarms

Like all active ingredients, especially chemical exfoliants, there are some possible risks and side effects to look out for when using glycolic acid, especially in sensitive areas like the underarms: 

  1. Increase UV sensitivity – AHAs like glycolic acid might lessen the effects of sun damage. However, they also destroy the top layer of skin cells, making the cells underneath more susceptible to more UV damage. Because of this, it’s imperative to use sunscreen every day.
  1. Irritation – This can happen if you use glycolic acid that is too strong, if you use it too frequently, or if you use it in very sensitive areas. You may experience redness, itching, burning, and even some swelling. 
  1. Hyperpigmentation – Even though glycolic acid is known to reduce the appearance of darkened patches of skin, if the product causes too much irritation, your skin can actually darken further in response.
