While having darker skin on your inner thighs is typically harmless, you may not like how it looks, and that’s okay! While you should always talk to your dermatologist before starting treatment, there are plenty of over-the-counter medications and home remedies that can potentially lighten your skin. We interviewed wikiHow’s board-certified dermatology partners to teach you all the best ways to lighten your inner thighs, what causes darkened skin, and how to prevent it in the first place.

How to Remove Darkness on Inner Thighs

FAAD board-certified dermatologist Mohiba Tareen, MD, recommends over-the-counter and prescription medications that contain retinol or azelaic acid to treat darkened inner thighs. Or, try home remedies, like rubbing your skin with honey, lemon juice, or turmeric. See a dermatologist before trying any treatment.

Steps

Section 1 of 5:

Trying Over-the-Counter Products

1. 
   1
   Visit a dermatologist first to get a diagnosis. Before beginning any form of treatment, dermatologist Lydia Shedlofsky, DO, recommends visiting a board-certified dermatologist to make sure the condition is benign. Once they know the main cause, they can recommend a good course of treatment.

   • Darkened inner thighs can be caused by a few different things. Chafing, sensitive skin, hormonal imbalances, or hyperpigmentation could be the culprit. Your dermatologist is the only person who can give you a true diagnosis.
   • Board-certified dermatologist Kaveri Karhade, MD, adds, “It is natural for the human body to have variations in skin pigmentation. Skin folds, such as the bikini area, tend to be a little darker than neighboring skin. While this is usually not of concern, a visit to the dermatologist is a good idea to rule out any treatable medical cause.”

   Choose a 2% hydroquinone cream to help lighten your inner thighs. Board-certified dermatologist Aanand Geria, MD, recommends using hydroquinone, which is an over-the-counter lightening cream available in a 2% strength. Hydroquinone slows down the production of melanin and also makes dark spots appear lighter. Apply it once a day to your inner thighs; stop using it if it causes hives or a burning sensation.

   • You can also use this cream on other parts of your body that have dark spots.
   • It usually takes about 2 months to start seeing results.
   • Dr. Geria adds that 4% hydroquinone is available with a prescription.

   Warning: At most, use hydroquinone cream for 4-5 months before taking a break. It’s important to give your skin some time to restore itself. If you want to continue using the hydroquinone cream, wait 2-3 months before beginning to apply it again.

   Invest in a retinol or vitamin C serum to lighten skin and improve its texture. “Most types of hyperpigmentation respond to retinols or prescription retinoids,” says board-certified dermatologist Kate Holcomb, MD. Rub a few drops of the serum into your thighs every night before going to bed. These serums may make your skin renew faster, meaning the dead cells will be gone and replaced with new, brighter ones more quickly.

   • In addition to retinol, Dr. Tareen also recommends using niacinamide, a form of vitamin B3.
   • For the best results, put the serum onto dry skin.
   • Dr. Holcomb adds that these products “can cause irritation, so many times, you have to go slow and use a moisturizer.”
   • Dr. Geria also recommends using over-the-counter vitamin C serums: “One that I really like is something called SkinCeutical’s C E Ferulic. That’s a very nice serum that’s going to help lighten up dark spots.”

   Warning: Don’t use retinol serum if you’re pregnant. Chances are, you and your baby would be okay with such a small topical treatment, but it’s still advised that you avoid it altogether while pregnant.
4. 
   4
   Try an acidic topical treatment to remove dead cells and lighten the skin. Look for products that include glycolic acid, azelaic acid, or kojic acid. These acids essentially strip away the top layer of skin to reveal brighter skin underneath. Apply the treatment every night before going to bed. Stop using it immediately if it causes a burning sensation or rash.

   • Dr. Tareen says azelaic acid is a popular over-the-counter and prescription option for brightening the skin.
   • Dr. Karhade says you should only use azelaic acid, kojic acid, and other forms of acid under the direction of a dermatologist.
   • It’s best to use these types of products in conjunction with a moisturizer, as they tend to dry out your skin. If you’re applying the acidic treatment at night, use a sensitive cream or coconut oil in the morning.
5. 
   5
   Use your OTC product every day for 6-8 weeks to see results. It generally takes some time for you to notice a visible change in your skin tone. Products that promise results overnight or within a week usually don’t work or contain harmful chemicals. Be patient and consistent with the application to see lighter inner thighs within a few months.

   • If after that time you still don’t see a difference, you may want to try a different product or discuss your options with your dermatologist.

Using Home Remedies

1. 
   1
   Mix lemon juice with a moisturizing oil to lighten dark patches of skin. Dr. Tareen says that the vitamin C in lemon juice is a natural skin-brightening agent. However, it can also dry your skin out, so it’s important to combine it with a moisturizing oil, like coconut oil, shea butter, or almond oil. Combine 2 to 3 US tbsp (30 to 44 mL) of oil with the juice from half a lemon, then massage the mixture into the affected area for 10 minutes. Wash the area when you’re done.

   • Because lemon juice is acidic, you may want to test it on your skin first to make sure it doesn’t burn or irritate your skin.
   • Certain forms of vitamin C are more effective than others, so it’s possible this method may not work for you.
2. 
   2
   Use aloe vera gel to help lighten and heal your skin. Aloe vera gel or aloe vera-based products can soothe irritated, chafed skin. Aloe also contains aloin, which could potentially lighten the skin. Apply a thin layer to the affected area for 15-20 minutes. There’s no need to rinse it off.

   • Make your own aloe vera gel using fresh aloe from an aloe vera plant, or use store-bought aloe vera gel.
3. 
   3
   Exfoliate the skin with a homemade sugar scrub. If the dark area is caused by a buildup of dead skin, exfoliating may help. Combine fresh lemon juice, a teaspoon (4 g) of sugar, and 1 US tbsp (15 mL) of honey to make a sugar scrub. Gently scrub the mixture into your inner thighs, then rinse when you’re done.

   • If you don’t want to make your own, buy a sugar scrub online or in-store.
4. 
   4
   Create an oatmeal yogurt scrub. Oatmeal can sometimes treat eczema and other inflammatory skin conditions. It’s also a gentler exfoliant than sugar. Yogurt contains lactic acid, which may also improve skin health. Make a paste with equal parts oatmeal and plain yogurt, then gently scrub it into the affected area. Wash the paste off when you’re done.

   • Feel free to add 1  tsp (4.9 mL) of honey as a moisturizer.
5. 
   5
   Apply honey to your dark spots to help them fade. According to Dr. Tareen, “Honey has soothing and anti-inflammatory properties and can help reduce hyperpigmentation. You can apply honey directly to dark spots on the skin for 10 minutes and wash it off with lukewarm water. This method can be followed every other day. Follow with a non-comedogenic moisturizer.”
6. 
   6
   Lighten your inner thighs by applying sliced or grated cucumber. Cucumbers have great antioxidants and vitamins A and C. They may help combat skin discolorations over time. Cut 5-6 slices of cucumber and simply rub them over the darkened areas for about 5 minutes. Or, cut more slices and leave them on your inner thighs for about 20 minutes.
7. 
   7
   Rub the area with a potato. This is an old folk remedy, but it’s believed that the catecholase enzyme in potatoes can lighten skin. Since there’s no harm in trying, slice a potato in half, then rub the inside over the affected area for at least 15 minutes. Wash the area when you’re done.
8. 
   8
   Consume or apply turmeric to your skin. Dr. Tareen says, “The active ingredient in turmeric is curcumin, which is not only an antioxidant, but a skin-brightening molecule. Turmeric can be taken orally to help prevent darkening of the skin due to its anti-inflammatory benefits, and when applied topically, it can help, over time, with skin brightening.”
9. 
   9
   Try a baking soda paste if you don’t have sensitive skin. Baking soda may help lighten and exfoliate the skin, but it can be too harsh and may worsen skin conditions. If you want to try it, mix equal parts baking soda and water, and apply a thin layer to your inner thighs. Leave the mixture on for about 15 minutes, then rinse.

   • Before trying this method, test the mixture on a small patch of skin to see how your skin reacts.
   • Since this method is so harsh, consider trying gentler methods or seeing a doctor for treatment.

Seeking Professional Treatment

1. 
   1
   Try laser treatments to reduce pigmentation without scarring. If you’ve already tried medications and home remedies, ask your dermatologist whether laser treatments are appropriate for your needs. These treatments are non-invasive and directly destroy the pigment cells in your skin. Just be aware that the healing process may be uncomfortable, especially if your thighs frequently rub together.
2. 
   2
   Consider a chemical peel to rejuvenate the skin. According to Dr. Geria, “Chemical peels basically peel away that dead skin on top that has the pigmented layers… It requires a series of treatments. Usually, we recommend about three, and each one is done on a monthly basis.” Chemical peels may dry out the skin, so be sure to use a good moisturizer if you choose to try them.

   • Dr. Geria recommends doing a chemical peel in the fall or winter, when there’s not too much sun.
3. 
   3
   Go for an aesthetic treatment to treat skin imperfections. There are several aesthetic treatments that may improve the appearance of your skin. These should be performed by a dermatologist or at another professional facility. Here are a few options for these treatments:

   • Microdermabrasion: An exfoliation treatment used to rejuvenate the skin.
   • Radiofrequency: A treatment that can lighten skin in addition to combating wrinkles and flaccidity.
   • Intense pulsed light: A type of light that targets the melanin in skin.

What causes dark inner thighs?

1. 
   1
   Chafing When your thighs rub together as you walk or exercise, it produces friction. Over time, this friction can cause the skin to become thick, itchy, and discolored. This process is known as post-inflammatory hyperpigmentation.

   • This friction also occurs when your thighs rub against tight clothing.
   • Post-inflammatory hyperpigmentation can also be caused by acne, eczema, or skin injuries. It’s more common in people with darker skin tones.
2. 
   2
   Sun exposure When you spend time in the sun, your skin creates more melanin to protect itself from damage. However, sometimes the skin doesn’t produce melanin evenly, resulting in patches of hyperpigmentation. If you’ve spent a lot of time in the sun and haven’t worn sunscreen, you may develop dark inner thighs.
3. 
   3
   Dry skin When your skin is dead or dehydrated, it can cause certain areas to look darker or duller. Dry skin doesn’t produce more melanin, but it can make darkened skin look more pronounced and uneven.
4. 
   4
   Hormonal imbalance Certain hormonal imbalances can cause your skin to darken in certain areas. You may notice dark patches of skin if you’re pregnant, lactating, menstruating, or if you have polycystic ovarian syndrome (PCOS). This process is called melasma.
5. 
   5
   Certain medications Some medications, such as hormonal oral contraceptives and some chemotherapy medications, can increase the amount of melanin your body produces. This may cause your skin to darken around your thighs or other areas where your skin bends or folds frequently.
6. 
   6
   Acanthosis nigricans Acanthosis nigricans is a skin condition that causes the skin to become dark and thick in body folds and creases. It typically affects the armpits, groin, and neck. This condition mostly affects people with obesity and can be a sign of prediabetes. In rare cases, it can be a sign of certain forms of cancer. See a doctor if you notice changes in your skin.

How to Prevent Dark Spots

1. 
   1
   Maintain a healthy weight so your thighs don’t rub together as much. The chafing caused by your thighs consistently rubbing against one another is one of the main culprits of dark inner thighs. While you should only lose weight if you want to, keep in mind that it may reduce the amount of chafing you experience.

   • Some people will experience thigh-rubbing regardless of their weight.
   • Try wearing spandex shorts underneath skirts or dresses to prevent your thighs from rubbing together while you’re walking.
2. 
   2
   Stop wearing tight pants to reduce chafing and protect your skin. Steer clear of fabrics that don’t let your skin breathe and that hug your thighs too tightly. Instead, look for pants that are moisture-wicking and that let your skin breathe. Cotton is a great choice, as are sport-specific pants.

   • Jeans are a major cause of chafed thighs. Make sure your jeans fit well and aren’t too tight or too loose.
   • If your pants are uncomfortable and cause chafing, but you need to wear them, apply a cream or powder to your thighs before getting dressed in the morning. Baby powder or similar products absorb sweat and may help keep you comfortable for longer.
3. 
   3
   Avoid tanning beds or exposure to the sun to prevent further darkening. Sun exposure increases the production of melanin, which will make dark areas even darker. Dr. Shedlofsky says daily application of sunscreen is “essential” for correcting hyperpigmentation. When you are outdoors, make sure to apply sunscreen with an SPF of 30 or higher to your entire body, including your inner thighs. Look for products that include zinc oxide or titanium dioxide and that promote “broad-spectrum protection."
4. 
   4
   Use body washes and shaving creams made for sensitive skin. Some skin care products are too rough for the sensitive skin of your inner thighs. If you are experiencing discomfort and irritation, especially after shaving, try switching out your normal products for ones that are gentler or made of natural ingredients.

   • Look for products that are soothing and moisturizing. Shea butter, coconut oil, and oatmeal are great ingredients that should calm, rather than irritate, your skin.
5. 
   5
   Visit your doctor if you feel you might have a hormonal imbalance. Sometimes there isn’t anything you can do topically to combat dark inner thighs. Hormonal imbalances or conditions like polycystic ovarian syndrome (PCOS) can cause skin tone changes. Your doctor is the best person to determine if this is true for you and to help you come up with a treatment plan.

   • Many pregnant women experience hyperpigmentation on their thighs, stomach, face, and hands. If this happens to you, expect the discoloration to fade in the months following birth.
