The application of petrolatum-based products, such as Vaseline, to minor cuts, scrapes, and burns serves to create a protective barrier. This barrier aids in moisture retention, promoting optimal healing conditions and preventing the wound from drying out and forming a hard scab. A common practice involves applying a thin layer of the product to the affected area and covering it with a bandage.
Maintaining a moist wound environment accelerates the healing process and can reduce the likelihood of scarring. The occlusive nature of petrolatum prevents excessive water loss from the wound bed, facilitating cell migration and tissue regeneration. Its use dates back to the late 19th century and has remained a widely accepted method for basic wound care due to its simplicity and effectiveness in promoting healing and preventing infection by creating a barrier against external contaminants.
