How to use lactic acid for dark knuckles

Lactic acid is a naturally-occurring acid produced by the body during exercise. It is produced by muscles that are using energy at a faster rate than they can produce it, which causes lactic acid to accumulate in muscle cells. The main purpose of lactic acid is to provide energy to the muscles by converting glucose into lactic acid in order to continue working.

The problem with this process is that the skin absorbs lactic acid, which can lead to dark knuckles and other areas on your hands and feet where you sweat most often. Lactic acid can also cause dryness and roughness in these areas, so it’s important to take steps to protect yourself from its effects and prevent damage from occurring.

It is, therefore, very important that you give your hands the necessary care to undo this damage and keep them in the best shape.

One of the most common hand-related complaints is knuckle hyperpigmentation or darkened knuckles, which can develop at any age. This occurs due to an increase in melanin synthesis in the skin covering your knuckles. Skin color is determined by the amount of melanin pigment in the skin – the more melanin, the darker the skin.

This article takes you through the different treatment options and self-care measures to lighten dark knuckles.


Causes of Dark Knuckles

A number of factors can contribute to the overproduction of melanin in the knuckles, including:

  • Hormonal changes or hormone-related disorders such as polycystic ovary syndrome (PCOS)
  • Poor hygiene
  • Use of cosmetics and/or fragrance-based chemical products
  • Work or sports that cause excessive friction on the knuckles such as boxing
  • Eczema
  • Psoriasis
  • Acanthosis nigricans
  • Diabetes
  • Dermatomyositis 
  • Addison’s disease or other autoimmune disorders
  • Vitamin B12 deficiency (1)(2)
  • Drug reaction
  • Malignancy
  • Genetics

Treatment for Knuckle Hyperpigmentation

The first-line treatment for knuckle hyperpigmentation depends on the underlying condition and includes:

  • Prescription medications, including topical vitamin D compounds, keratolytics such as topical retinoids (tretinoin 0.05%), and oral melatonin
  • OTC topical products, including zinc sulfate, salicylic acid ointments, glycolic acid creams, arbutin, azelaic acid, and kojic acid, which may be used as monotherapy for milder cases (3)

If these primary interventions fail to deliver the desired results, your doctor may recommend the following clinical procedures as second-line treatment to fade the hyperpigmentation:

  • In-office skin peeling using chemical agents such as glycolic acid 20%–70%, salicylic acid 20%–30%, trichloroacetic acid (TCA) 10%–25%, and Jessner’s solution, along with some topicals (4)
  • Laser treatment with low-fluence Q-switched Nd:YAG, Er:YAG, or CO2 laser, to be immediately followed by daily application of a broad-spectrum sunscreen
  • Microdermabrasion to exfoliate the dark, damaged skin so that it can be replaced by new, brighter layers from underneath
  • Cosmetic camouflage

Self-Care Measures

self-care measures to lighten dark knuckles

The following self-care measures can accelerate lightening of your knuckles:


  1. Knuckle hyperpigmentation is a common symptom of vitamin B12 deficiency. (1) Vitamin B12 plays an important role in collagen synthesis and generation of new skin cells. You can increase your vitamin B12 intake through foods such as meat, poultry, fish, and dairy. You can also consume vitamin B12 supplements or vitamin B12-fortified foods for the same.
  2. A fairly common endocrine disorder called polycystic ovary syndrome (PCOS) can also cause knuckle hyperpigmentation. (27) Although there is no cure for PCOS, it can still be managed through proper medical treatment, which aims at correcting the hormonal imbalance underlying this condition. Plus, several lifestyle changes such as reducing weight, proper diabetes management, healthy eating with a good dose of vitamins A and C, and stress control may also help reduce the severity of the symptoms and enhance the efficacy of the prescribed treatment.

When to See a Doctor

Dark knuckles are rarely a cause for concern, but they can sometimes stem from health issues that need medical evaluation and treatment.

So, it’s best to get yourself checked by a doctor if the hyperpigmentation occurs all of a sudden or continues to darken even after the necessary skin care and preliminary treatment.

Plus, you must seek medical help if you experience any of the following symptoms, which can point to a more grievous cause: 


  • Fatigue
  • Itching
  • Dizziness
  • Pain
  • Inflammation
  • Oozing

Most-Asked Questions About Dark Knuckles

Can I bleach my darkened knuckles?

avoid bleaching to prevent dark knuckles

No. Bleaching with OTC creams such as 1% hydroquinone creams or bleaching powder solutions can cause burns or can damage your skin in other ways. Hydroquinone is banned in some countries; therefore, use it only if your doctor suggests it.

Can I use lemon juice to treat my knuckle hyperpigmentation?

Lemon or lime juice is replete with vitamin C, which is known to exhibit antityrosinase activity, which inhibits melanin formation. (30)

But because lemon juice is highly acidic, it can be caustic on your skin and can even disrupt its natural pH balance. Plus, topical use of lemon juice can render your skin more susceptible to solar damage, which will inadvertently worsen your hyperpigmentation.

For these reasons, skin experts generally advise against using this remedy topically for skin concerns such as dark knuckles. 

Can orange peels help lighten my darkened knuckles?

No. Even though research suggests that orange peels (Chinese orange variety) are potent tyrosinase inhibitors, (31) only their alcoholic extracts are credited with this property and not the peel itself. Therefore, direct application of orange peels will most likely have no effect in reducing the hyperpigmentation of your knuckles.

Final Word  

Not all cases of darkened knuckles warrant medical intervention, especially when there is no underlying illness at play. Even simple factors such as negligent hand hygiene, excessive exposure to sunlight and harsh detergents, or too much friction against the knuckles can make the affected skin darker.

In such cases, taking better care of your hands should be enough to bring your darkened knuckles back to their true color. This includes proper handwashing, regular moisturizing to keep the skin soft and hydrated, wearing gloves when handling chemical irritants, and applying sunscreen to block out solar radiation.

If your condition fails to improve, becomes worse, or is accompanied by new worrisome symptoms despite all these self-care efforts, you must seek medical consultation to identify the root of the problem and get appropriate treatment accordingly.

Dark knuckles causes

Dark pigmentations of the knuckles can be as a result of various factors. It may be the reaction to a certain intake of drugs, It may also be inherited and could be a sign of vitamins the body is lacking.

Nevertheless, the factor associated most with black knuckles is as a result of the strong acidic substance found in products used on the skin, breaking down the melanin present in it. These products are commonly referred to as bleaching creams.

Drug reactions

Other than bleaching creams usage of these drugs is linked to why the knuckles could get darker than other parts of the fingers.

These drugs are:

  • Nicotine acid
  • Estrogen therapy
  • Growth hormone therapy
  • Protease inhibitors

Drug containing these substances causes the knuckles to have darker pigmentation.

Lack of Vitamin B-12

Vitamin B-12 is a water-soluble vitamin that helps to create red blood cells. The red blood cells help to carry oxygen through the body. When the body does not have enough Vitamin B-12, it could cause the knuckles to start losing its color and get darker.

The symptoms of lack of vitamin B-12 include:

  • Shortness of breath
  • Dizziness
  • Fatigue
  • Headache

The body system extracts this vitamin from foods such as egg, milk, cheese, and meat. When the body gets little of these foods the skin starts to lose its glow and the knuckles amidst other areas of the body that has higher pigmentations get darker.

Skin lightening products

Many skin lightening products contain Hydroquinone or Lipohydroxy acid which is derived from salicylic acid. These acids bleach the skin by breaking down the number of melanocytes which produces melanin that helps to give the skin a brown color. These compounds are artificial and are recommended mostly to be used for treating skin issues like; melasma, acne scars, eczema and dark spots.

When products containing these acids are used other than for skin treatment, the skin reacts to it especially parts of the skin that have hyperpigmentations. The knuckles are part of the body parts that have hyperpigmentations, so it proves really hard for bleaching products to penetrate and lighten them.

There are more natural ingredients and simpler ways to get rid of dark knuckles, they are as follows:


The varieties of soy can help lighten the knuckles, It could be either in the bean or milk form. for use, it is recommended to apply on the surface of the knuckles and rinse out after a couple of minutes or leave in longer as desired. The nutrients in soy suppress skin pigmentations from surfacing.

Ellagic Acid

This is extracted from fruits like cherries, pomegranates, and strawberries. Often intake of these fruits and making scrub mixtures with it brightens the knuckles. The acid stops one of the enzymes that helps in the secretion of melanin in the skin.

Sugar and olive oil

Sugar and olive oil mixed together as a scrub helps to exfoliate the dead skin cells on the knuckles. Sugar removes the dead skin cells on the surface of the knuckles while olive oil moisturizes the skin, giving it the glow you desire.

Your knuckles are the most exposed part of your body. If you’re like me, you probably spend a lot of time outdoors and have begun to notice that your knuckles are starting to age faster than the rest of your hands. That’s where lactic acid can help! Lactic acid is a mild exfoliant that helps skin look more youthful by removing dead skin cells from the surface layer. It also helps fade dark spots and hyperpigmentation over time. So if you want to get rid of those ugly dark spots on your knuckles, read on for how to use lactic acid safely at home!

Try lactic acid first

Lactic acid is a natural ingredient that’s found in sour milk and yoghurt. It exfoliates the skin, helping to lighten dark spots by removing the top layer of dead skin cells.

Try lactic acid first. If you have sensitive skin, start off with a small amount on your inner arm or behind your ear before applying it to your knuckles. You could also try an at-home peel made from lactic acid instead of purchasing a product that contains it as an active ingredient.

Avoid using it if you are allergic to dairy

First, be sure to avoid lactic acid if you are allergic to dairy. If this is the case, there are plenty of other skin lightening treatments that can help you get rid of dark knuckles.

Use with an exfoliator

  • Use a gentle exfoliator. Exfoliating scrubs and cleansers can be helpful in removing dead skin cells, but it’s important to find one that won’t cause irritation or further dry out your knuckles. Avoid using a scrub with grains, microbeads, or any other abrasive ingredients like pumice stones. You should also avoid anything too harsh on the skin: if your hands are sensitive to begin with and you’re trying to treat dark knuckles, then no matter what else you do, you’ll probably still see some redness and dryness after washing your hands.
  • Apply lactic acid in between exfoliation sessions (or before). Lactic acid is made from milk sugar—it’s milder than alpha hydroxy acids such as glycolic acid and salicylic acid because it doesn’t penetrate as deeply into skin layers—and leaves behind water-binding humectants that help keep moisture around for longer periods of time than when these creations are just sitting there doing nothing (aka “water retention”).

Lactic acid doesn’t remove hyperpigmentation

As a skin care ingredient, lactic acid does a great job at exfoliating. It’s also an effective treatment for acne and hyperpigmentation (dark spots on the skin). In recent years, however, many people have been using lactic acid to try to lighten dark knees and knuckles. This is not recommended because it doesn’t work!

Lactic acid cannot remove hyperpigmentation—it only helps reduce the appearance of dark spots once they’re there. To truly get rid of them altogether would require lasers or chemical peels performed by professionals at clinics like those run by dermatologists or plastic surgeons.

lactic acid can help to lighten dark knuckles.

You can use lactic acid to lighten dark knuckles.

  • Do not use it if you are allergic to dairy.
  • Use it with an exfoliator. You should wait at least one night after using an exfoliator before applying lactic acid for best results.
  • Lactic acid does not remove hyperpigmentation, so don’t expect it to fade dark knuckle spots on its own.

We’re excited to share these tips with you. We hope they help you achieve a brighter complexion and clear skin.

If you’ve ever had dark knuckles, you know how frustrating it can be. It’s not like the rest of your skin tone, and it can make your hands look older than they are. Luckily, there are ways to lighten those knuckles that don’t involve expensive creams or painful procedures. All you need is some shea butter, coconut oil and banana!

Melt the shea butter and coconut oil in a microwave oven.

To start, place the shea butter and coconut oil in a microwave-safe bowl. Microwave it for 30 seconds and then stir. Then, microwave again for another 30 seconds, stir again, and let sit until it’s completely melted.

Add the mashed banana pulp to the melted combination.
  • Add the mashed banana pulp to the melted combination.
  • Mix well and transfer it into a clean glass container.
Apply the paste to your knuckles.
  • Apply the paste to your knuckles.
  • Use a clean cloth or cotton swab.
  • Apply the paste to your knuckles and allow it to absorb into your skin. The best time to apply the paste is at night before bed because it will have time to sit on your skin throughout the night and work its magic while you sleep!
Allow the mixture to absorb into your knuckles for 5 to 10 minutes.

After you have applied the paste, allow it to absorb into your skin for 5 to 10 minutes. You can do other things during this time; for example, you could wash your hands or put on lotion. You could also practice some stretches or yoga moves!

  • Wipe off the paste with a damp towel.

You can use a soft towel to wipe off the paste. Don’t scrub too hard, as this might irritate your skin or cause it to peel prematurely. If you used turmeric or comfrey root powder in your paste, don’t use soap afterward because this could remove some of the healthy properties of these ingredients.

A simple home remedy can help you lighten dark knuckles.

If your hands are often exposed to the sun, then the skin on your knuckles will be darker than the rest of your hands. These spots are usually not painful or itchy, but they can look unsightly and make you uncomfortable. Thankfully, there are several ways that you can lighten them without having to visit a dermatologist or pay for expensive treatments at a spa. Read on to learn about these options and decide which one is right for you!

  • Turmeric

This spice has long been used as an ingredient in cooking because of its wonderful flavor and medicinal properties. It’s also known as “Indian saffron” because like saffron (a type of flower), turmeric contains pigments called curcuminoids that give it its distinctive yellow coloration — so much so that it’s sometimes referred to as “poor man’s saffron.” Curcuminoids have antioxidant properties that make them helpful in treating various diseases such as arthritis or Alzheimer’s disease; however they aren’t necessarily specific enough when it comes down to targeting just one condition specifically though because different parts of the body may respond differently depending on how much inflammation exists there already from previous injuries sustained over time (such as those suffered during athletic competitions).

The benefits of a home remedy for dark knuckles are that you can use it when you need it, the ingredients are readily available, and it’s inexpensive. You can also apply this method to your hands and other areas like elbows, knees or even your neck with similarly good results. If you want to keep your skin looking fresh and youthful, try using this trick before going out in public so people don’t see how old they really look!
