Why do we need greasy moisturizers to hydrate our skin? Isn’t water enough?

In: Biology

I believe the greasy nature of moisturisers creates a layer on the skin which helps lock moisture in

You’re waterproof, so applying water doesn’t hydrate your skin.

I’m sure others will be able to explain better, but there are moisturizers that aren’t greasy-feeling (I hate my hands feeling greasy, the one I use is Gold Bond healing hand cream; I’m sure there are others).

Your skin is waterproof because of skin oils. Water on its own simply beads up and rolls off your skin, more or less. Soap can actually dissolve the oils which dries your skin out – yes, *washing* your skin can *dry* it!

Moisturizers and lotions and whatnot serve the same purpose as skin oils. “Oil and water don’t mix”, right? So water doesn’t do anything to moisturize your skin.

Asked my dermatologist which lotion to use for dry skin.

“The greasiest one you can stand”

Our skin produces oil to help retain elasticity and aid in wound healing (among other things).

Some people produce too much (oily). Some people not enough (dry). Below is short extract from a journal explaining how our skin requires a 3:1:1:1 ratio of omegas/FFAs (fats) in our diets whilst optionally applied topically to our skin.

Hemp interestingly has “co-evolved” with humans – explained by Dr. Sunil K. Aggarwal who calls this humankind’s “evolutionary garden” — the collection of plants, fungi, and animal secretions that people have cultivated since prehistory.

Hemp seeds produce an oil which provide us with the perfect 3:1:1 ratio of omega-6 -3 -9 essential fatty acids, this matches the ratio recommended by the World Health Organization (WHO) for optimal health.

“application of a mixture of cholesterol, ceramides, and essential/nonessential free fatty acids (FFAs) in an equimolar ratio allows normal barrier recovery, whereas any 3:1:1:1 ratio of these four ingredients accelerates barrier (skin) recovery.”

Co-evolution with plants and animals takes a very long time utilizing give and take and ususally results in amazing benefits.

The main goal of moisturizers is to help you retain moisture, not to moisturize the skin. Moisturizers help replace some of the natural oils in your skin that get washed or dried off.

All our skin is covered in a thin layer of grease, in some parts of the body more than others. That makes you waterproof and keeps your skin hydrated, as water what it does is in fact dehydrate your skin (even if it sounds contradictory).

I have a skin condition that prevents my body of generating enough grase, making my skin dry as fuck.
