How Vaseline Works as a Skin Protectant
Petrolatum has been a go-to for dermatologists for decades. It’s recognized by the American Academy of Dermatology (AAD) as a safe and effective option for sealing in moisture, particularly on damp skin.
Unlike some lotions that evaporate quickly, petrolatum helps trap existing moisture. One study found it accelerates barrier recovery rather than hindering it.
Here’s a quick comparison of common moisturizer types:
| Type | How It Works | Best For | Example Duration of Hydration |
|---|---|---|---|
| Lotions | Lightweight, water-based | Normal to oily skin | Short-term |
| Creams | Thicker, with emollients | Dry skin | Medium |
| Ointments (like petrolatum) | Occlusive barrier | Very dry or irritated skin | Long-lasting |
This makes it especially helpful during colder months or for areas prone to dryness.
