Yes: SLS and its relatives are not just a shampoo issue. Sulfates are in many shower gels, facial cleansers, and liquid soaps for the same reason as in shampoo: they clean well, lather a lot, and are inexpensive. The difference is that the skin on your body and hands is washed more frequently and with less care than your hair, and that is where the effect of each wash accumulates. Our solid shower gels, those in the Evasion line, and our liquid hand soaps (which we call soaps, but they are not soap) are formulated without sulfates.
What a sulfate does to the skin
It is the same mechanism as in hair. A surfactant surrounds grease and dirt and lets water wash them away. Sulfates, such as sodium lauryl sulfate (SLS) or sodium laureth sulfate (SLES), do this so well that they do not distinguish between excess oil and the oil the skin needs: the lipids in the stratum corneum, which form the barrier that retains water.
With a shower gel containing sulfates, every bath removes a little of that barrier. If your skin is oily and resilient, you barely notice. If it is dry, if the weather is cold, or if you shower more than once a day, you may feel tightness when stepping out of the shower, experience flaky skin on your legs, or have itchy skin when wearing clothes. This effect is so well-known that SLS is used in dermatology as a reference irritant in tolerance studies.
In shower gel
A bath is the longest and hottest wash of the day, and hot water strips away lipids on its own. Adding a powerful surfactant worsens what is already happening. A sulfate-free base cleanses sweat and sebum just as effectively, but leaves more of those lipids where they belong. You notice it in how your skin feels a while later, not in how much lather the gel produced.
Our solid shower gels and those in the Evasion line are sulfate-free. You can choose a solid format, such as the Bourbon Vanilla Solid Shower Gel or the Mango and Coriander one, which is also soap-free and has a skin-neutral pH, or a liquid one, like the Coconut Evasion Shower Gel. The entire line is under shower gels.
In hand soap
Hands are the part of the body that gets washed the most times per day. With a soap containing sulfates, ten daily washes mean ten passes of a strong surfactant over skin that has almost no sebaceous glands to recover. This is why the hands of people who wash them frequently tend to get dry first.
We call them soaps because that is what everyone searches for, but they are not: they are liquid cleansers, without soap in the technical sense. Our liquid hand soaps, like the Olive and Bitter Orange or the Coconut one, are sulfate-free and dye-free. They clean just as well, and it helps to finish with hand cream. They are in liquid hand soap.
What to expect when switching
Our gels and soaps lather very well, so the difference you will notice is this: your skin remains comfortable, not "squeaky clean." If you are coming from a product with sulfates, you might feel a little less lather; lather does not measure how well a product cleans. If you are coming from a gel with sulfates, give it a couple of weeks: your skin will usually need less cream after showering.
How to tell if a product contains sulfates
Read the list of ingredients (INCI). Sulfates appear with names ending in sulfate: sodium lauryl sulfate, sodium laureth sulfate, ammonium lauryl sulfate. The list goes from highest to lowest concentration, so if they are among the first ingredients, they are the cleansing base. You can also look for "sulfate-free" on the packaging.
If you want to understand the other side of the issue, soap, read what soap is and why our cleansers are soap-free, and about shampoo, why use a shampoo without sulfates, without SLS, and without salt.
Frequently asked questions
Do shower gels contain sulfates?
Many do, especially the foamier ones. Ours, both solid and from the Evasion line, are sulfate-free.
Does a sulfate-free shower gel clean less?
No, it cleans more gently. You might feel a little less lather than with a product containing sulfates, but it removes sweat and sebum just the same.
Why does my skin get dry after showering?
It is usually a combination of three things: very hot water, a cleanser with sulfates, and not moisturizing afterwards. Lower the water temperature, switch to a sulfate-free gel, and apply cream while your skin is still damp.
Do Yves Rocher hand soaps contain sulfates?
No. Our liquid hand soaps are sulfate-free and dye-free.
How do I know if my soap or gel contains SLS?
Look at the ingredients list for names ending in sulfate, such as sodium lauryl sulfate. If it appears among the first ingredients, it is the cleansing base.
