For many people of color, darker underarms are completely normal. But if you’re looking to even out your skin tone, this guide offers practical tips and natural remedies to help you get there.

Causes of Dark Underarms

Before jumping into solutions, it’s important to understand what causes dark underarms in the first place. Some of the most common culprits include:

Featured on BlackDoctor
  1. Shaving: Shaving can cause the skin under your arms to darken due to irritation and friction.
  2. Dead skin buildup: Accumulation of dead skin cells can lead to darker underarms.
  3. Deodorants and antiperspirants: Some products can react with your skin, leading to darkening.
  4. Friction: Tight clothing or constant rubbing can darken the skin.
  5. Hyperpigmentation: Some individuals may naturally have darker underarms due to genetics or hormonal changes.
  6. Medical conditions: Acanthosis Nigricans can be linked to insulin resistance.

Knowing the root of the problem can help you make better choices for your skin and avoid making the issue worse.

Natural Remedies

Try any of these natural methods for fresher, cleaner and lighter underarms:

Apply cider vinegar

The pH levels and acidity levels in ACV are great for sloughing off dead skin and getting rid of dark skin under your arms because they keep your pores clear and kill odor-causing bacteria.

Potato juice

Did you know that potatoes are like natural bleach? Try rubbing a potato slice under your arms after a shower regularly. You are bound to see your dark skin fade.

Milk

Ever heard of using milk in a DIY face mask? Well, the same goes for your armpits! The lactic acid is a great exfoliant and acts as a deep cleanser. Try applying cold milk to your underarms daily, or just when you want a cool, refreshing cleanse.

Lemons

Lemons, like ACV, have high acidity levels, making them great for exfoliation. They are also known to remove pigmentation, hence why lemons are often used to lighten hair. Ever use a lemon to clean your hands? That’s because they are great for killing germs. Try a slice or two under your arms. In the warm summer months, keep some sliced lemons in the fridge. This is great for a refreshing feel.

Tomatoes

Lycopene counteracts the actions of free radicals, causing tomatoes to be a great antioxidant for the skin. They are also known to have skin-lightening properties. Use slices of tomato under the arm for at least 15 minutes at a time to begin to see a difference.

Oranges

The properties in oranges make them a great toner and astringent. Try making the orange peel into a scrub, giving it a double whammy as an exfoliator, too!

Lifestyle Habits That Make a Difference

Changing a few daily habits can go a long way in reducing and preventing dark underarms:

1. Switch to Natural Deodorants

Many commercial deodorants contain aluminum and alcohol that can irritate and darken sensitive skin. Look for products with natural ingredients like coconut oil, shea butter, and baking soda—or even make your own!

2. Choose Breathable Fabrics

Tight or synthetic clothing traps sweat and causes friction. Opt for cotton and looser fits that allow your skin to breathe.

3. Exfoliate Gently

Use a natural exfoliator—like sugar mixed with olive oil—two to three times a week to remove dead skin cells and prevent buildup. Always moisturize afterward to soothe the skin.

4. Rethink Hair Removal

Shaving can cause tiny cuts and lead to pigmentation over time. Waxing or laser hair removal may be less irritating alternatives. If shaving is your go-to, use a clean razor and always soften the skin first.

When to See a Dermatologist

Sometimes, natural remedies aren’t enough, especially if the pigmentation is linked to a medical condition. You should consult a dermatologist if:

  • The discoloration spreads or worsens.
  • You notice thickened or velvety skin (a sign of Acanthosis Nigricans).
  • There’s itching, burning, or any other form of discomfort.
  • Professional treatments like chemical peels, topical retinoids, or laser therapy may be recommended in persistent cases.

Dark underarms are more common than you might think, and there’s absolutely no shame in them. But if they bother you, know that you have options—safe, affordable, and effective ones that you can try right at home.

The key is patience, consistency, and a little self-care. Whether you go all-natural or seek medical help, you deserve to feel good in your skin, underarms included.
