Whether you can put Vaseline on a rash depends on the type of rash. Vaseline (petroleum jelly) can be beneficial for some rashes, but it's not suitable for all.
Here's a breakdown:
-
When Vaseline might be helpful:
-
Dry, irritated skin: Vaseline acts as an occlusive moisturizer, meaning it creates a protective barrier on the skin's surface, preventing moisture loss. This can be helpful for rashes caused by dry skin, eczema, or contact dermatitis (from irritants). The referenced Vaseline® Healing Jelly Original and Vaseline® Intensive CareTM Sensitive Skin Relief are designed for this.
-
Protecting broken skin: The barrier created by Vaseline can also help protect broken or cracked skin from further irritation and infection, promoting healing.
-
-
When Vaseline might not be helpful:
-
Infected rashes: If the rash is infected (bacterial or fungal), Vaseline can trap moisture and potentially worsen the infection. Signs of infection include pus, increased redness, swelling, pain, or fever.
-
Heat rash: Vaseline's occlusive properties can trap heat and sweat, exacerbating heat rash.
-
Allergic reactions: Although rare, some people can be allergic to ingredients in petroleum jelly. If you notice increased irritation after applying Vaseline, discontinue use.

What to do before applying Vaseline:
- Identify the type of rash: Try to determine the cause of the rash before applying any treatment. If you're unsure, consult a doctor or dermatologist.
- Cleanse the area: Gently clean the affected area with mild soap and water and pat dry.
- Consider a cool compress: As suggested in the references, a cool compress can help soothe inflamed skin before applying any ointment.
-
Alternatives to Vaseline:
- Other moisturizers: If Vaseline doesn't feel right or if you're looking for something with added ingredients, consider other gentle, fragrance-free moisturizers. The "Question short answer" from the references suggests investing in a good moisturizer.
- Ointments: Depending on the rash, your doctor may recommend a specific ointment (e.g., a topical steroid for inflammation or an antifungal cream for fungal infections).
In conclusion, while Vaseline can be a useful treatment for dry, irritated skin and protecting broken skin, it's not a one-size-fits-all solution for all rashes. Identify the cause of the rash and consult a healthcare professional if you are uncertain about using Vaseline or if the rash worsens.
