Which Cleanser Is Right For My Skin Type?
Which Cleanser Is Right For My Skin Type?
There are three basic types of cleanser – 1)soaps; 2) surfactant (or detergent) cleansers; and 3) soap-free (or oil) cleansers. It may be difficult to know which cleanser is right for your skin type, with all of the choices available. Below are the basic differences to help you choose.
Soaps can be divided into bar soaps and liquid soaps. Soaps have been around for thousands of years. Essentially, a soap is classified as a product created by combining an oil or fat with lye, or sodium hydroxide. If this process doesn’t occur, it can’t be called a soap. An example would be WEBA’s Lavender/Rosemary Bar Soap. Soaps tend to be more basic, with a pH between 10 and 12, depending upon how much sodium hydroxide is left behind and whether or not they are “superfatted.” Unlike our bar soaps, which retain glycerin and use premium butters like cocoa and shea, commercial soaps remove the glycerin for sale. It’s important to read labels; not all bar soaps are created equal. Bar soaps travel well and cost less to use than liquid soaps.
Liquid soaps are made by combining fats or oils with potash, or potassium hydroxide. This is a “hot process” reaction – the ingredients are heated for a period of time until the reaction is done, after which water is added. If less water is added, you have a gel. More water produces a thinner formula. These also tend to be more basic. A major difference between liquid and bar soaps is that with liquid soaps, a preservative must be added due to the high water content. Again, read labels to see what preservatives or other ingredients are used.
Soaps, because they clean so well, are generally fine for people with combination or oily skin, although soaps can have ingredients added to them which make them more moisturizing for all skin types. Many also find liquid soaps convenient and more hygienic than bar soaps. It’s really a matter of personal preference.
Surfactant (detergent) cleansers
Surfactant cleansers include detergents (e.g. dish detergent, laundry detergent) and are generally synthetics (made in a lab). Many of the “Beauty Bars” are, in fact, a combination of surfactants formed into a bar under high pressure. Some surfactants like Sodium Lauryl Sulphate have fallen into disrepute lately, but there are other naturally-derived surfactants like Coco Betaine, which cleans more gently compared with soaps. These tend to be better for persons with problem skin (acne, ezcema, etc.). This class of cleansers is popular in shampoos, as well, because many have conditioning properties.
Soap-free (oil) cleansers
Soap-free cleansers can include oil-free cream and oil cleansers. They are good for dry, combination and oily skin and are good at removing makeup. Oil-free cleansers consist entirely of surfactants, some synthetic and some naturally-derived, with perhaps a wax and conditioning agents. Reading the labels on these products can be confusing because of the chemical names. What is polyethylene? (A plastic resin). What is Methyl Lactate? (A solvent.) It can also be difficult to determine whether ingredients come from plants or animals. Most have water as their first ingredients, necessitating a preservative. And just because these products are soap-free doesn’t mean that you can’t react to one or more ingredients. Companies are required to provide common names on their labels; you can search for information about an ingredient if you’re not sure what it is.
Oil cleansers are also soap-free, but usually contain a combination of oils along with other beneficial ingredients. Again, check the label if you want to be sure that you’re not sensitive to an ingredient like nuts or certain essential oils. One example of an oil cleanser is our Whole Earth Body Actives Gentle Facial Cleansing Oil and Makeup Remover. Ours is free of essential oils, perfumes and dyes. These also tend to be used exclusively for the face, unlike other cleansers. They tend to be less irritating to the eyes.
Our recommendation? It’s probably best to use a variety of cleansers, depending on your family’s skincare needs and their particular use. For travel, bar soaps are best. When skin is dry, try a cream cleanser. To remove makeup and excess oils, try an oil cleanser. Regardless of which you choose, always check labels so you know what is going on your skin, and to avoid irritation.
