Friends…… please stop using Vaseline/aquaphor

Want to disrupt your hormones? Lower your testosterone? Then yes, rub Vaseline all over yourself.

Vaseline is made from petroleum.
It’s a byproduct of crude oil refining.

Crude oil contains compounds such as polycyclic aromatic hydrocarbons that are endocrine disrupting, Carcinogenic and Genotoxic. (This equals lower testosterone, infertility, hormone disruptions)

Full stop. Why would you put that on your skin?or lips?

Yes, it’s occlusive.
It creates a physical seal on the skin.

the problem is

Your stratum corneum (main skin barrier) is not just a surface to coat.

It’s made of corneocytes (think of bricks) surrounded by intercellular lipids (think mortar)

Those lipids are biologically active. They regulate permeability, hydration, and barrier signaling.

Petroleum jelly does NOT integrate into that lipid matrix.

It just sits on top and reduces water loss mechanically.

It doesn’t replenish lipids.
It doesn’t support barrier repair.
It doesn’t contribute structural fatty acids.
Again, motor oil on your skin 😷

Beef tallow does what Vaseline quite literally cannot

Tallow contains palmitic acid, stearic acid, and oleic acid.

Those are fatty acids already found in the skin’s natural barrier.

Palmitic and stearic acid provide structural reinforcement.

Oleic acid helps integrate and spread within the lipid matrix.

Instead of suffocating the skin, it supports the mortar between the bricks.

Vaseline is an inert sealant derived from crude oil.

Tallow is biologically compatible. With human skin, derived from beef fat

Big difference….
