Soapless Cleansers

Even though soapless skin cleansers use different ingredients from most traditional soap formulas, they still clean your skin in a similar way. To remove dirt and oil from your skin, all cleansers must be able to attract both water and fat. To do this, their molecules have an oil-loving component -- called a lipophilic part -- and a water-loving component -- the hydrophilic part. This combination of lipophilic and hydrophilic elements is called a surfactant.

A surfactant is a detergent that allows water to wash away the oil and dirt from your skin by decreasing the surface tension of water. Surfactants are both lipophilic -- oil loving -- and hydrophilic -- water loving: The lipophilic part captures the dirt and then the hydrophilic part rinses it away. The lipophilic part is typically composed of fatty acids, but in soapless cleansers, it's usually made of chemicals derived from petroleum and other oils, which are less damaging to skin [source: New Zealand Dermatological Society]. In addition, soapless cleansers have more added moisturizers and humectants than most soap, which help prevent skin from drying.

Another reason some traditional bar soaps can be harmful to sensitive skin is because of its high pH -- it can disturb the pH of the outermost layer of skin called the stratum corneum. The stratum corneum protects the inner layers of skin, but when harsh soaps come in contact with it, the soap dries the skin, making the stratum corneum more permeable to chemicals and other pollutants [source: Elias].

Chemical advances in soap and soapless cleansers have given people with sensitive skin many cleansing options. Read on to learn more about the benefits of soapless skin cleansers.

Because soapless cleansers moisturize the skin and strengthen the stratum corneum, they're a good choice for people with sensitive skin. But soapless skin cleansers can also benefit people with dry or oily skin. If your skin is oily, a soapless cleanser with a low pH will clean your skin without drying it out -- removing too much oil can actually cause oil glands to go into overdrive [source: Bouchez]. And because people with dry skin have little oil to protect their skin, soapless cleansers are also a good choice -- the added moisturizers will help the skin retain water instead of drying it like bar soap [source: Mayo Clinic].

These cleansers are also less likely to produce soap scum. The combination of soap and hard water -- water that's high in calcium -- can create a soap scum that leaves a residue on your skin. Soapless cleansers also have a longer shelf life than soap -- soap deteriorates easily when it comes in contact with water, but soapless cleansers can last for years.

One of the greatest benefits of soapless skin cleansers is that they keep your skin moisturized. You can help your body retain that moisture by taking warm, short showers instead of hot, lengthy ones -- too much heat can dry out your skin. Applying a moisturizer within three minutes of bathing or showering can also help you retain the moisture that the water and cleanser added to your skin [source: American Academy of Dermatology].
