Vitamin C works best on treating dark spots, dullness, and hyperpigmentation, and walnut shells bring out the natural tone of the skin by removing the dead skin. The walnut shell in this Mama earth lip care is a great exfoliator, and Vitamin C is best known for boosting the glow. Thus, taking a bath with Vitamin C and Walnut Shell will help you achieve the skin's natural radiance. However, we recommend using well-formulated skincare products containing these ingredients, as using a chemically-enriched product could harm your skin.
