Potatoes are  believed to have skincare benefits due to their high levels of Vitamin C and other antioxidants. They can be used to brighten and even out the skin tone, reduce dark circles and puffiness around the eyes, and hydrate the skin. Additionally, the starch in potatoes can help to absorb excess oil and reduce the appearance of acne. To use a potato for skincare, you can cut a potato into slices and place them on your face, or mash the potato and apply it as a face mask. It is also common to make a potato juice and use it as a toner or adding it to your mask.
