Yes, Bag Balm can be used on lips, especially for severely chapped lips.
Bag Balm contains occlusive ingredients like petrolatum and lanolin, which create a protective barrier that helps to seal in moisture and promote healing. According to Dr. Waldorf, Bag Balm "seals lips well overnight." It is often recommended for use on any part of the body that is dry, chafed, or cracked.
Therefore, Bag Balm can be an effective solution for chapped lips due to its moisturizing and protective properties.
