Acanthosis Nigricans is a skin condition characterized by dark, thickened, velvety patches typically found in skin folds such as the neck, armpits, and groin. It is often associated with insulin resistance, obesity, hormonal disorders, or medications.

While addressing the underlying cause is key to long-term improvement, a variety of natural remedies may help lighten affected areas and soothe irritation. These remedies can be used alongside lifestyle changes for optimal results.

Top Home Remedies for Acanthosis Nigricans

1. Apple Cider Vinegar

Apple cider vinegar helps exfoliate the skin and restore pH balance. Mix equal parts of ACV and water, apply to the affected area with a cotton ball, leave for 10 minutes, then rinse. Use once daily.

2. Aloe Vera

Aloe vera contains antioxidants and healing enzymes that help lighten pigmentation and repair damaged skin. Apply fresh aloe vera gel to the patches and leave it on for 20–30 minutes before rinsing. Repeat daily.

3. Coconut Oil and Baking Soda

This combination acts as a gentle exfoliator. Mix one tablespoon of coconut oil with enough baking soda to form a paste. Massage onto the skin for a minute and leave it on for 10 minutes before rinsing. Use 2–3 times weekly.

4. Lemon Juice

Rich in vitamin C, lemon juice can help lighten dark areas. Apply freshly squeezed lemon juice to the skin for 10–15 minutes, then rinse. Do not use on irritated or broken skin. Use sunscreen afterward, as lemon juice increases photosensitivity.

5. Turmeric and Milk

Turmeric has anti-inflammatory and skin-lightening properties. Mix one teaspoon of turmeric with two teaspoons of milk to make a paste. Apply to dark patches, let dry, then rinse. Repeat daily.

6. Tea Tree Oil

Diluted tea tree oil may help reduce irritation and fungal overgrowth in affected areas. Mix a few drops of tea tree oil with a carrier oil like jojoba or coconut oil and apply to clean skin once daily.

7. Oatmeal Scrub

Finely ground oats act as a gentle exfoliant. Mix with yogurt or milk and use as a scrub to remove dead skin cells and brighten skin tone. Rinse thoroughly and moisturize afterward.

8. Lifestyle and Nutritional Support

  • Reduce sugar and refined carbs to support healthy insulin levels
  • Exercise regularly to improve insulin sensitivity and circulation
  • Increase fiber intake with fruits, vegetables, and whole grains
  • Consider supplements like chromium, berberine, or alpha-lipoic acid (consult your healthcare provider)
  • Stay hydrated and avoid harsh skin care products that may worsen discoloration

When to See a Doctor

While natural remedies can help manage Acanthosis Nigricans, consult a healthcare provider if symptoms worsen, spread rapidly, or are accompanied by other concerning symptoms. If you notice a sudden appearance or a red line or streak near the area, seek medical evaluation to rule out underlying conditions or infections.

For those with Acanthosis Nigricans, applying Camphorated Oil will bring better circulation to the splotches on your skin. It might take a long time, maybe 1 to 2 years or longer, but try that. I used it for stretch marks and a scar and they went away in 2 years. I have a silky smooth new skin in those places now!


Dietary Changes

I'm pretty sure that I now know what I have Acanthosis Nigricans. My neck, cheeks (face), under arms and inner thighs are black and my skin is caramel. Those areas are not only black but like thicker and really I've tried every lotion and nothing works.

After reading that this is caused by insulin resistances which I think I might also have, I almost lost it. There are images online where they've done test with people who have Acanthosis Nigricans and put them on a strict diet and the Acanthosis Nigricans vanished.

I am going to start a 1200 calorie diet and 2hrs of cardio every day. I might start with just one hour of cardio and then one hour of anaerobic exerciser and work my way up to the 2hrs. I am also doing Jillian Michael's 30-Day Shred and will post my results in about 30days to see if anything had changed.

I though I was going to have this for ever and to think that I just need to lose weight and cut out my bad foods and this will go away is crazy!

Please people do your research everything is out there =)

I thought I had PCOS and these dark patches were due to vitiligo, but I think it is Acanthosis Nigricans. I've had this forever (20 years?). I have shown it to all of my doctors and NONE of them ever mentioned insulin resistance and metabolic syndrome. THIS IS NEGLIGENCE ON THEIR PART!!! A book I bought tonight made the connection. I have been using coconut oil in my baths as well as tea tree oil. It seems to be helping and fading it.

Please follow a high fat, low carb diet to reduce your insulin resistance, reduce weight and in turn reduce your acanthosis nigricans.

A calorie restricted diet per se will not help if it is laden with carbohydrates. It's the composition of the diet that matters here.

A good, healthy diet and exercise regimen will get rid of acanthosis nigricans. I've had it since I was a teenager, but didn't know what it was until I saw a dermatologist in my twenties. I was at 230 pounds at that time, so I focused on taking care of my body and lost 55 pounds. The acanthosis nigricans disappeared.

So, the solution? Take care of yourself!

Acanthosis Nigricans:

Thought this might be of some interest. I had embarrassing dark thick patches of skin under my arms, my neck, and my thighs as a child (noticed more so as I entered puberty.) Was always told I didn't wash enough. I WAS NOT OVERWEIGHT. It was horrible. Tried expensive medical creams, everything, to no avail. As I got older ... it simply went away. It went away when I was overweight.

I have two children, a girl and a boy, and they both acquired it about the same age as I was.

I would have never had it diagnosed correctly had it not been for an Army doctor who had seen many different things in practicing medicine all over. I did acquire diabetes later in life, after this went away. And after it went away, I acquired terrible scalp psoriasis which I have to do this day. We think my dad's brother had both acanthrosis nigricans AND psoriasis. He was not overweight.

Guess they are both autoimmune conditions in common ... Just an interesting fact to add to the fodder.

Quite by accident, we found that mineral spirits is a cosmetic quick fix (wipe gently) for Acanthosis Nigricans, but not a cure. And that the condition will show itself again after 2-3 weeks.

For acanthosis nigricans, ayurvedic neem balm is awesome to fade away the dark areas, it really works! But also exercise and diet are important.

Have you tried a body or face scrub with skin lightening properties. I struggled with that as well. Especially my right elbow. Also EVO with some essential oils like clove, peppermint, and especially tea tree oil. I'd use organic qtips to apply or organic cotton make-up remover pads. Then after cleaning the area that way I would apply an antifugal. I don't know how heavy you are. I weighed 363 lbs at 5 ' 10". I went to FL to help my Mom in February of 2006.My son got married that June. I lost 180 lbs just cutting out carbs.I wore a size 28 dress when I left and a size 12 at my son's wedding.I know before this sugar and salt was my thing. Extra sugar feeds candida. We all have it. When I gave up sugar it improved greatly. That's why the antifungal helps I think .

For acanthosis nigricans, try zinc supplements. I was told it was a stress fungus. My 2 year old niece had it as well. We took zinc tablets as 'prescribed' on the bottle, not capsules tablets, she took a child's zinc tablet. In 2 weeks we were cured. Love, andrea c
