Walnut scrubs contain natural exfoliating particles that remove dead skin cells and unclog pores. This can help with blackheads and whiteheads, and reduce the appearance of blemishes. Walnut scrubs can nourish your skin with essential nutrients, such as vitamin E, to make it softer and suppler. Walnut oil is also rich in omega 3 and 6 fatty acids, which can be nourishing and moisturizing for dry or irritated skin.
