How to Use Vitamin C For Underarms

Even though Vitamin C is generally well tolerated, there is a correct way to use it.

Always do a Patch Test First

  • Since your underarm is very sensitive, choose a small area of skin and do a patch test first. 
  • Apply a small amount of the Vitamin C product and wait 24 hours. If no negative reaction occurs, you may use it on the whole area. 
  • However, if you develop a rash, irritation, or any other side effects, discontinue the product immediately.

  • Do not skip your deodorants and antiperspirants.

What To Look For When Buying Vitamin C

Serums and other skincare items may contain Vitamin C in certain concentrations and formulations. 

Vitamin C’s potency and skin-related effects might vary depending on its formulation.

Consider purchasing vitamin C products from your dermatologist’s office or a reputable retailer. 

Check to confirm that it has:

  • a clinical formulation that contains an active form of vitamin C (for example, L-ascorbic acid)
  • a strength of 10 percent to 20 percent
  • a pH lower than 3.5

This combination has been studied in most clinical trials and is considered the safest.

The manufacturer’s websites and ingredient pages usually have this information available.
