Different bars of soap on a marble countertop

Answer:

All soaps can irritate the skin, but some contain ingredients that make them more likely to cause irritation than others, especially among people with sensitive skin.

Here are five important tips to help you select a soap that is less likely to cause skin irritation:

  1. Look for a fragrance-free product
  2. Be wary of products containing certain surfactants (including sodium lauryl sulfate (SLS), cocamidopropyl betaine (CAPB), or diethanolamine (DEA))
  3. Avoid certain preservatives (including methylisothiazolinone and other related isothiazolinones)
  4. Skip "antibacterial" soaps and be cautious with alpha hydroxy acids
  5. Don't consider "natural" or "organic" cleansers to be safer or more effective
