Yes, Vaseline is plain white petroleum jelly (petrolatum)
Vaseline is the brand name for plain white petroleum jelly, which is chemically identical to petrolatum—a purified mixture of semi-solid hydrocarbons derived from petroleum. The terms are interchangeable in medical and dermatologic contexts 1.
Chemical Identity and Composition
Petroleum jelly (petrolatum) is a refined petroleum product that consists of a mixture of hydrocarbons. Vaseline Petroleum Jelly is simply a branded version of this same substance 1. The manufacturing process involves refining crude petroleum to create a purified, white, semi-solid product that is safe for topical use.
Clinical Use and Properties
From a dermatologic perspective, plain white petrolatum/Vaseline functions as:
- An occlusive moisturizer that reduces transepidermal water loss by permeating throughout the stratum corneum interstices rather than forming a surface barrier 2
- A vehicle for medicated ointments and wound care applications 1
- A recommended emollient in atopic dermatitis management, though guidelines note that specific moisturizer ingredients cannot be recommended over others based on limited evidence 3
Important Clinical Distinctions
While Vaseline is plain petrolatum, not all petrolatum-based products are plain petrolatum. For example:
- Aquaphor Healing Ointment is a petrolatum-based product but contains additional ingredients beyond plain petrolatum, which may increase wound reactivity (52% redness vs 12% with plain white petrolatum) 4
- Products labeled as "petroleum jelly" should contain only petrolatum, but always verify ingredients if concerned about additives
Practical Considerations
Plain white petrolatum (Vaseline) is generally safe with rare serious adverse effects 3. However, be aware that:
- It can cause comedones with repetitive application to certain areas like the lip margin 5
- Despite myths about comedogenicity, it is not inherently acne-causing when used appropriately 1
- Application technique matters—using it after bathing while skin is damp can reduce the "greasy" sensation while maintaining efficacy 6
