If you're like me, you shave your legs, and often too. I've tried everything, from shower gel, to body wash, to try and get the same baby soft feel that foaming shaving gel leaves on my skin.
But I've noticed that using foaming shave gel (like Aveeno, or Skintimate) dries out my hands. Sometimes the skin on my wrists feels irritated after I use it.
Have you noticed this too when using certain foaming shaving products? If you've experienced something similar, please read on, so you can join me in avoiding the shaving gels/creams not suited for sensitive skin.

I used a generic foaming shave gel, for the Aveeno brand shave gel, called "up&up" today, hoping it wouldn't dry out my hands. I've changed brands at least five times this year, looking for a shaving gel that was different, and more moisturizing, which wouldn't dry out my hands or cause any irritation. Unfortunately, up&up isn't any different from the other five products.

So, I went through the ingredients list on the back of the up&up can (water, palmitic acid, triethanolamine, stearic acid, isobutane, cocamide DEA, benzyl alcohol) and did some research on these ingredients, hoping to find the ingredient/s responsible for leaving my skin dry and irritated. Here's what I found:
Triethanolamine, the third ingredient on the back of the up&up shave gel, is what's called a
surfactant. A
surfactant reduces the surface tension of liquids so that the liquid spreads out instead of forming into droplets. Surfactants, like
Triethanolamine, can be used as foaming agents, among other things (detergents, dispersants, etc.).
Triethanolamine also causes skin dryness. In other words,
Triethanolamine is a drying substance in shave gel (it's also in Skintimate--I checked) that is added to produce the foaming affect of the gel.
I think it's safe to say that
Triethanolamine is what causes my skin to dry out after using a foaming shave gel like up&up or Skintimate. My best advice is to stick to a regular body wash or soap which does not include this ingredient, or the words "foaming" or "foaming action" on the label.
I believe that the skin redness I experienced from using the up&up shaving gel, was caused in part by
benzyl alcohol. The word "alcohol" by itself sounds drying, but that's not why I blame it for being a skin irritant. It's the fact that
it is a skin irritant, in people who have an allergy to
benzyl alcohol.
Even though
it's rare, it's possible to have an allergy to
benzyl alcohol (an "
allergic contact dermatitis" meaning an "allergic skin reaction") and even a severe allergy where
benzyl alcohol causes an anaphylactic reaction. An allergy to benzyl alcohol is also related to allergies to latex. (And what do you know? I have an allergy to latex too, which causes a similar allergic reaction. Who would've guessed?)
The other ingredients, like
oleth-20, were mostly foaming agents, and also what's called a
propellant. A
propellant just squeezes the product out of the can when you press down on the lid.
Isobutane is also a
propellant.
Isopentane (not to be confused with Isobutane) is also a propellant, and also a solvent, and a substance that controls viscosity (thickness of a substance)
Cocamide DEA is a chemically modified form of coconut oil. My guess is that
Cocamide DEA was modified to make it less perishable/more preservable? Just an educated guess.
Stearic acid comes from animal and vegetable fats and oils. It's a waxy solid.
Palmitic acid is found in natural fats and oils. It's a waxy acid used in the manufacture of soap, candles, and food additives.
My favorite find is
sorbitol because apparently it's used for everything from use as a sweetener in candies and cough syrups, to use as a laxative. Ahem. Really?
