Vaseline is generally not recommended for treating or preventing milia, and in some cases, it may even contribute to their formation.
Why Vaseline Might Worsen Milia
-
Occlusive Nature: Vaseline (petroleum jelly) is highly occlusive. This means it creates a barrier on the skin, preventing moisture from escaping. While this can be beneficial for dry skin, it can also trap dead skin cells and sebum (oil) beneath the surface.
-
Trapped Keratin: Milia are small, white bumps that occur when keratin (a protein found in skin, hair, and nails) becomes trapped beneath the skin's surface. Vaseline's occlusive properties can exacerbate this by preventing the natural shedding of dead skin cells, leading to keratin buildup.
-
Slugging and Milia: The skincare trend of "slugging," which involves applying a thick layer of Vaseline to the face as the last step in a nighttime routine, aims to lock in moisture. While this can be helpful for some skin types, it can increase the risk of milia formation, especially for those prone to them.
Alternatives to Vaseline for Milia-Prone Skin
If you're prone to milia or have them currently, consider these alternatives:
- Exfoliants: Gentle chemical exfoliants like salicylic acid (BHA) or glycolic acid (AHA) can help remove dead skin cells and prevent them from becoming trapped.
- Retinoids: Topical retinoids, such as retinol or tretinoin, promote cell turnover and can help dislodge existing milia and prevent new ones from forming.
- Lightweight Moisturizers: Opt for non-comedogenic, lightweight moisturizers that won't clog pores. Look for oil-free formulations.
- Professional Extraction: A dermatologist or trained aesthetician can safely extract milia using a sterile needle. Avoid attempting to extract them yourself, as this can lead to scarring or infection.
In Summary
While Vaseline can be beneficial for some skin conditions, its occlusive nature makes it less ideal for milia-prone skin. It can potentially worsen the condition by trapping dead skin cells and keratin, leading to more milia formation. Consider using alternative skincare ingredients and treatments that promote exfoliation and cell turnover.
