Does Vaseline Hydrate Skin?
No, Vaseline doesn't directly hydrate skin. Instead, it acts as an occlusive, creating a barrier on the skin's surface that prevents moisture loss. This helps retain the skin's natural hydration. While it doesn't add moisture itself, it effectively traps existing moisture, keeping skin feeling softer and less dry.
Vaseline, or petroleum jelly, is an oil-based product. It forms a protective film over the skin, sealing in existing moisture and preventing water from evaporating. This is why it's effective for treating extremely dry or cracked skin. Several sources confirm this mechanism:
- Medical News Today: States that the oily film seals in moisture, helping keep skin hydrated.
- Healthline: Describes Vaseline as a good, cost-effective moisturizer for dry skin, emphasizing its barrier function.
- Reddit (r/SkincareAddiction): Notes that Vaseline hydrates indirectly by preventing water evaporation.
- Vaseline.com: Clearly explains that occlusives like Vaseline don't moisturize in the same way as lotions or creams; they prevent moisture loss.
Is Vaseline a Moisturizer?
While Vaseline is often used as a moisturizer and is highly effective in preventing dryness, it's crucial to understand the distinction. It's not a true moisturizer in the sense that it doesn't add moisture to the skin. Instead, it's an occlusive, preserving the skin's existing hydration. One Reddit post (r/MakeupAddiction) explicitly states that Vaseline is not technically a moisturizer but rather a barrier preventing moisture loss.
Practical Applications
- Dry Skin: Vaseline is excellent for treating very dry, cracked, or chapped skin. It provides a protective barrier, allowing the skin to heal.
- Slugging: The popular "slugging" technique involves applying a layer of Vaseline overnight to seal in the benefits of other skincare products.
- Makeup Removal: Vaseline's occlusive properties make it effective for removing makeup, especially waterproof mascara.
