Try drinking it as eggplant tea.

Purple eggplants full of anthocyanins are in season.

At my house, we dry eggplant skins in the sun and drink them as tea. When harvesting eggplants, there are many with skins that are too tough to eat, so since it feels like a waste to throw them away, we dry them like this and brew them into tea. They say eggplants are good for eyesight, help whiten the skin, and even aid in removing toxins and purifying the body. How about trying eggplant skin tea for your skin?
