The role of Vaseline in tattoo beauty: Vaseline is a mineral wax that may form a protective film on the surface of the skin, making it difficult for the skin's moisture to evaporate. Moreover, it adheres to the skin for a long time and has a good moisturizing effect, especially suitable for use on dry skin, so its effect in scar removal is also quite obvious; Vaseline is also non irritating, less prone to spoilage, and does not cause sensitivity in the human body. It is particularly suitable for people who are prone to alcohol allergies!
