[Research] Petroleum jelly can cause allergic contact dermatitis on damaged skin

Beauty Tips For Body Care
Relatively recently (2 months ago) I over-exfoliated my skin. Dehydrated skin, damaged moisture barrier - you guys know it. So, of course, I layered various products on my skin and topped it off with vaseline. At first it was ok, and started healing my skin well, but after 1-2 days, I noticed my skin started itching badly. Thinking it was due to some ingredient in one of the products I was layering under, I began reducing the products I was using under the vaseline, until I was using vaseline alone. As I was still experiencing itching, I decided that maybe it was the occlusivity of pure petroleum jelly that was making me itch.2 days ago, I tried QV cream on my face. It contains petrolatum, but I thought that it would be alright since it isn't heavily occlusive like vaseline is. Initially it was soothing, but after a while I noticed redness on my face, followed by itching a day later.After some googling I pulled up this article: https://www.medscape.com/viewarticle/552008_3 which notes that while an individual may not normally have any adverse reaction to petrolatum, it can cause allergic contact dermatitis on damaged skin. It does state that this can vary among brands due to the differing amounts of allergenic contaminants (allergens are most likely polycyclic aromatic hydrocarbons), as well as that white petrolatum tends to be less sensitising than yellow petrolatum (vaseline contains yellow petrolatum). I'm not sure how to find out whether the 'petrolatum' in moisturisers is white or yellow, but white is more commonly used.While most people on this sub do use vaseline on damaged skin without negative reactions, I thought I'd share this as I've found that some others experienced itching as well after searching on this sub and asking in the DHT. Looks like I'll probably have to resort to buying me a tube of LRP Cicaplast!
