How Long Do Home Remedies Take to Show Results?

The time it takes to observe noticeable results is not the same for everyone. It varies from person to person depending on the severity of pigmentation, the individual’s skin type, the home remedy used and how your skin responds to it. Typically, it takes several weeks to months of consistent application to notice visible results.

How to Prevent Dark Underarms?

It is always wiser to prevent the condition beforehand than to treat it at its peak stage. Here are some preventive tips to follow:

  • Wear fabrics or clothes that cause minimal friction and irritation to your skin.
  • Use a mild chemical exfoliator and avoid harsh scrubbing or exfoliation.
  • When shaving your underarms, always use shaving cream and change the razors frequently.
  • Opt for a mild deodorant that moisturises your underarms and is alcohol-free and fragrance-free.
  • Avoid excess waxing or shaving. Instead, opt for advanced options like laser hair removal.

When to See a Dermatologist?

You may be using the home remedies consistently for a course of time. However, you should see a dermatologist when:

  • The darkness persists despite consistent application of home remedies.
  • When you notice itching, rashes, or pain, in addition to darkened underarms.
  • When the darkness or discolouration spreads to other areas of your body.
  • If you are unsure about the cause of a sudden or severe darkening in your armpits.

Consult a dermatologist immediately who can identify the underlying reason and recommend a safe and effective treatment to address the darkness.
