The Salad Dressing Theory

difference between oil and water in the skin

difference between oil and water in the skinI often hear people tell me that their skin is dry because they haven’t been drinking enough water. In fact, I’ve even had other estheticians reprimand me for not drinking enough water to cure my own dry skin. This persistent myth drives me crazy because it’s not even scientifically possible.

First, let’s define the terms. Dehydrated skin lacks water. Dry skin lacks oil. Any skin type can be dehydrated. In fact, most skin types are dehydrated because so many things we do strip water from our bodies. Since the skin is the first line of defense, even dry air can steal water from your skin.

Now let’s talk about my salad dressing theory. Oil and water don’t mix in your skin, just like they don’t mix in a vinaigrette. You have to shake a salad dressing to get both flavors. It’s the same in the skin; one cannot replace the other. Healthy, balanced skin has just enough of each.

Drinking water is good for you for many reasons. Not one of those reasons is because it moisturizes your dry skin. Since dry skin lacks oil, the only thing that solves the problem of dry skin is adding an oil. I like healthy, botanical oils like jojoba or argan oil. If you want to eat your way to moisturized skin, try avocados, flax seed, or nuts. Drinking water actually won’t hydrate your skin either. It’s virtually impossible to drink enough to hydrate from the inside. The best way to solve a dehydration problem is to add a hydrating serum to your daily routine.

Oily skin doesn’t necessarily need a moisturizer; it has more than enough oil, by definition. It needs a hydrator. This is exactly what an oil-free moisturizer is since there are no oils to moisturize. I do think that oily skin can benefit from a lotion simply because it helps to seal the water into the skin, but truly oily skin can just use a serum and be fine. Dry skin needs to be moisturized, which is how we add the proper oils to skin. Since dry skins are often dehydrated, these skin types may want to use a hydrating serum as well.

It’s important that you understand the difference between these terms so that you can be sure to treat your skin appropriately. You can’t solve your dryness with water. This isn’t a pass to skip water drinking completely, but, as always, remember to treat your skin for what is actually wrong to get the best results.
