Dark inner thighs can develop when the skin produces extra pigmentation called melanin. A healthcare provider may refer to this condition as hyperpigmentation.
Anyone may experience dark inner thighs, regardless of their skin tone.
In the following sections, we cover the treatments and home remedies a person with dark inner thighs can try to help reduce the appearance of the dark patches. We also discuss the possible causes and when to see a doctor.
Treatments and home remedies
Dark inner thighs themselves are not usually harmful, so they may not necessarily require treatment. However, some people may wish to reduce or eliminate darker areas of skin.
It is always best for a dermatologist to evaluate the cause of a person’s dark patches. Unless a person has an accurate diagnosis and can begin appropriate treatment, the dark areas may persist or recur.
There are several potential treatment options a person can try, including home remedies, over-the-counter (OTC) medications and creams, and medical treatments.
The following are some potential methods a person can try to reduce or eliminate the appearance of dark inner thighs.
Colloidal oatmeal and yogurt
Some research has shown that colloidal oatmeal may help reduce the appearance of dark inner thighs if they have developed due to eczema.
Other research has suggested that the microorganisms in yogurt may also promote skin health.
To create an oatmeal and yogurt cream, combine equal parts yogurt and colloidal oatmeal. Then, apply the cream to the affected area and leave for about 15 minutes. Finally, wash and dry the area.
People often use aloe vera to treat chafed skin, as it can help soothe the area.
There is limited research in this area, but some studies suggest that aloe vera may also help reduce dark areas on the skin.
To use, rub aloe vera cream or gel directly onto the affected area of the skin. It is not necessary for a person to rinse off aloe vera after application.
Rub potatoes on the skin
There are many people who believe that rubbing potato slices on the skin will help reduce areas of darkness. However, scientific research to support this claim is limited.
In one old study from 1991, researchers found that an enzyme in potatoes called cathepsin D helped heal the skin of wounded rats when the team applied it externally.
Although it may not be effective, a person can try cutting a potato into slices and rubbing a slice over the affected area for around 10 minutes. After applying the potato slice to the skin, clean and dry the area.
