Kalisa’s Question:
What can you tell me about Neutrogena Deep Clean Invigorating Cleanser/Mask? Specifically, is there any additional benefit to my skin of using it as mask (leaving it on for three minutes) as opposed to merely washing my face with it?
The Right Brain’s Answer:
To our suprise, Neutrogena does indeed recommend that this cleanser can be left on and used as a mask. We quote:
This revolutionary formula works as a daily cleanser or 3-minute mask. It foams instantly to dissolve dirt, oil and makeup. Skin tingles as the cooling lather deep cleans to leave skin feeling energized and shine-free for hours. For more intensive cleansing, use it as a mask. As it dries, you’ll feel it working deep within the skin’s surface to absorb shine-causing oil and pore-clogging impurities.
Why do we find this suprising? Let’s take a look at the ingredient list to find out. Drug store.com lists the ingredients this way:
Active Ingredients: Water, Methyl Gluceth 20, Sodium Laureth Sulfate, Lauryl Glucoside
Inactive Ingredients: Disodium Lauroamphodiacetate, Polyethylene, PEG-80 Sorbitan Laurate, Panthenol, Dimethicone PEG-8 Meadowfoamate, Polyquaternium-7, Sodium Benzotriazolyl Butylphenol Sulfonate, Menthol, Acrylates/C10-30 Alkyl Acrylate Crosspolymer, Disodum EDTA, DMDM Hydantoin, Sodium Hydroxide, Synthetic Wax, Ultramarines, Blue 1, Fragrance
If we ignore preservatives, fragrance, etc., and just focus on the functional ingredients we can break it down this way:
Ingredients that clean your skin:
Methyl Gluceth 20, Sodium Laureth Sulfate, Lauryl Glucoside, Disodium Lauroamphodiacetate, PEG-80 Sorbitan Laurate, Dimethicone PEG-8 Meadowfoamate, Polyquaternium-7
Ingredients that form a film on your skin and feel like a mask:
Polyethylene, Acrylates/C10-30 Alkyl Acrylate Crosspolymer, Synthetic Wax
Based on the presense of the mask type ingredients, this does look different than a typical cleanser – it appears to be designed to have a mask like feel to it. But how good of a mask is this? Typical masks contain clay or some kind of film forming polymer that really tighten the skin as it dries. Becaus this formula is different and because it contains so many cleansing ingredientes that will tend to soften the film so we doubt formula one would give you that strong tightening effect. Based on looking at the formula, our guess is this product would be a really good cleanser but it wouldn’t be a great mask.
But our real concern is about leaving this much surfactant on your face for so long. Surfactants, even relatively mild ones like this formula uses, can irritate skin. This product also contains menthol which is a known irritant.
The Beauty Brain’s Bottom Line:
Based on looking at the ingredients, we think that the risk of drying out your skin would outweigh any potential benefits. That’s our opinion without doing any testing so take it with the proverbial grain of salt. If anyone has tried this, let us know.
