Yes, you can rub potato on your face daily, especially if you're aiming to address issues like dark circles, hyperpigmentation, or dullness. The starch in potatoes has anti-inflammatory properties that can benefit your skin. You can either rub potato slices on your face or apply potato juice.
However, keep in mind that while potato is generally considered safe for the skin, some people might experience itching or irritation with daily use. It's best to start with using it a few times a week and gradually increase the frequency if your skin tolerates it well.
Remember that while potato can offer some benefits, it's not a magic solution for all skin concerns. If you're experiencing severe skin issues, it's always best to consult a dermatologist for professional advice.
