Vaseline is widely used as a skin moisturizer to prevent dryness and protect the skin barrier. It is commonly applied to chapped lips, cracked heels, and rough elbows to soothe and heal the skin. In medical settings, it is used as a protective barrier for minor cuts, burns, and abrasions to promote healing and prevent infection. Vaseline is also utilized in cosmetic routines to remove makeup, condition eyelashes, and soften cuticles. Additionally, it serves as a lubricant for small mechanical parts and prevents rust on metal surfaces. In some cases, it is applied to leather items to maintain their flexibility and prevent cracking.
