White patches on skin can be caused by many problems, including infections, allergies, or even an autoimmune disorder. White dots on skin are actually pretty common, and can be either permanent or temporary. Sometimes skin cancers and can cause a white spot on skin, but these are very rare. If you have white patches on your skin, you are likely dealing with something much simpler. Here are a few of the most common reasons why you might have white patches, white dots, or white spots on skin.

Vitiligo
This is a hereditary condition in which your skin loses pigment, leading to white patches or white dots on skin. This can happen to anyone no matter what their skin color is, but it is much more common in those who have darker skin. No one really knows what causes vitiligo.

How it affects your skin: The patches of white skin can be tiny or they can spread over the body over time, leading to a complete change in appearance for those who are most affected by it. The skin itself does not change; just the color of it does.

Home remedy
Ginkgo Biloba:
This popular herb is an antioxidant and helps boost your immune system. It can help reduce the problem and spur new pigment. Forty to eighty milligrams of the herb three times per day is usually recommended.

Coconut Oil:
This soothing oil fights fungi, bacteria and inflammation, as well as induces new pigment in the skin. Apply it two to three times a day for at least two weeks and look for improvement.

Ginger:
This heightens blood circulation, which can help with vitiligo. Put fresh ginger on a small area and let it sit until it dries. You can also try drinking the juice of a ginger root and mint leaves for a few days.

Babchi:
The active ingredients in these seeds can help reduce hypopigmentation. You can use it by applying the oil to the skin, then exposing it to sunlight for 15 minutes. Another option is to soak the seeds in ginger juice for three days, dry the seeds in the sun, grind them into a powder and drink about one gram per day with a glass of milk for 40 days.

Red Clay:
Red clay is also high in copper content. To use this, blend the red clay with ginger juice and put it on the affected area, leaving it until it dries. Use this daily until you see good results.
