6 Practical Uses and Advantages of Vaseline
Petroleum jelly, a thick, waxy substance derived from oil, has been a trusted skincare product for over a century, following its accidental discovery during the oil-drilling process [2]. Its recommended use on eczema-prone skin centers on its powerful ability to protect and repair the skin barrier.
As an occlusive agent, petroleum jelly reduces transepidermal water loss (TEWL), helping to maintain skin hydration and create optimal conditions for the skin to heal and feel better [1]. Dermatologists often favour petroleum jelly for eczema management due to its gentle nature, lack of preservatives and fragrances, and its unlikelyhood to cause irritation or allergic reactions, even in sensitive skin, including babies and those with severe skin conditions [1][3].
Specifically, petroleum jelly:
- Provides a protective barrier that locks in moisture. - Supports skin barrier repair by preventing dryness and cracking. - Is free from irritating ingredients found in many cosmetic serums or creams, which can exacerbate eczema symptoms. - Is affordable and encourages consistent use, which is crucial for eczema care [1].
However, potential risks associated with petroleum jelly for eczema-prone skin are minimal but worth noting:
- Due to its occlusive nature, it can be comedogenic (pore-clogging) for some individuals, potentially worsening acne if used on acne-prone areas [3]. - Since it does not contain anti-inflammatory ingredients, it does not directly reduce eczema inflammation; it should be used in conjunction with other eczema treatments such as corticosteroids or prescribed medications. - Rarely, if the skin is broken and there is a risk of infection, thick occlusive products like petroleum jelly could trap bacteria and potentially worsen infections—though this is generally uncommon [3].
In conclusion, petroleum jelly is highly recommended as a safe, effective moisturizing and barrier-repairing product for eczema-prone skin, with an excellent safety profile and minimal side effects. Using petroleum jelly regularly can help reduce dryness and irritation associated with eczema, but it should be part of a broader eczema management plan advised by a healthcare provider [1][3].
It's also worth noting that people with respiratory conditions like asthma should consult a doctor before using petroleum jelly near the nose or mouth, as using it inside the body could potentially cause breathing difficulties [4]. Additionally, people should buy petroleum jelly from a reputable source to avoid harmful components, particularly unrefined petroleum jelly that may contain carcinogenic contaminants like polycyclic aromatic hydrocarbons [5].
Lastly, petroleum jelly is flammable and should be stored in a cool, dry environment away from fires, smoking, and open flames [6]. Purified forms of petroleum jelly, such as Vaseline, have a low risk of exposing users to carcinogens and other harmful ingredients [7].
While petroleum jelly is often recommended for eczema management due to its skin-healing properties and gentle nature, it's important to consider that some individuals might find it comedogenic, potentially worsening acne on acne-prone areas. On the other hand, petroleum jelly lacks anti-inflammatory ingredients, so it should be used in conjunction with other eczema treatments. Furthermore, for individuals with respiratory conditions like asthma, it's advisable to consult a healthcare provider before using petroleum jelly near the nose or mouth.
