Here's a more detailed explanation:
- Petroleum Jelly as a Moisturizer: Petroleum jelly works as an occlusive, which means it creates a physical barrier on the skin. This barrier prevents water from evaporating from the skin's surface, thus keeping it hydrated.
- Vaseline as a Brand: Vaseline is a specific brand that produces and sells petroleum jelly. While there are other brands of petroleum jelly, Vaseline is one of the most well-known and widely recognized names.
- Mechanism of Action: Both petroleum jelly and Vaseline function in the same way. They don't actually add moisture to the skin. Instead, they trap the skin’s existing moisture, preventing it from escaping. This is why it is often recommended to apply petroleum jelly or Vaseline after showering or when the skin is already moist.
- Usage: Both can be used on various parts of the body, including hands, body, and face, to maintain skin hydration. For example:
- Applying it on dry, cracked heels helps retain moisture and accelerates healing.
- It can be used as a lip balm to prevent chapped lips.
- Applying a thin layer on the face at night can help prevent moisture loss.
- Reference Information: As per provided reference, both petroleum jelly and Vaseline create a barrier preventing water from leaving the skin, helping the skin retain its moisture.
Therefore, when you talk about using petroleum jelly to moisturize, you are discussing the function and benefit of using Vaseline. Vaseline is a specific brand of this product, like Kleenex is to tissue.
