Studies and expert opinions highlight that keeping skin moist can aid recovery from minor dryness or irritation. For example, the American Academy of Dermatology notes petroleum jelly’s role in maintaining moisture for better overall skin comfort.
Salt, particularly fine sea salt or table salt, brings a natural texture to the mix. When combined thoughtfully, it can act as a physical exfoliant—gently buffing away surface dead skin cells to reveal fresher-looking skin underneath.
But here’s the interesting part… many viral trends suggest applying this blend overnight, yet most reliable sources describe it as a short-contact scrub rather than a leave-on treatment. This distinction matters for safety and results.
Understanding the Potential Benefits of This Combination
When used correctly, petroleum jelly provides deep hydration by sealing in moisture, while the salt offers mild mechanical exfoliation. Together, they create a simple DIY option that some people incorporate for smoother texture.
Moisturizing Support: Petroleum jelly locks in hydration, which can make skin feel softer and more supple after use.
Gentle Exfoliation: The coarse particles help slough off dull surface layers, potentially improving the look of roughness on areas like elbows, knees—or very carefully on the face.
Everyday Accessibility: Both ingredients are inexpensive, widely available, and free from added fragrances or complex chemicals.
Research on individual ingredients backs some of these effects. For instance, occlusive agents like petroleum jelly are well-documented for reducing transepidermal water loss, helping dry skin feel more comfortable. Physical exfoliants, including salt-based ones, are commonly used in body scrubs to promote a refreshed appearance.
But that’s not the full picture…
