Most bars of “soap” that you purchase and may be using to cleanse your face are technically not soap, but contain detergents. What’s the difference? Soaps are gentler than detergent bars, which are too harsh for your skin and can strip away essential oils.
Unless you are using soap and not detergent on your skin, you risk irritation and dryness of your skin. Legally, detergent cleansers cannot be termed “soap,” which is why many detergent cleansers do not use the word “soap,” but will typically call their products “bars.”
Soaps are typically composed of primarily natural ingredients and simple formulas. Detergents usually contain synthetic ingredients and are chemically complex.
An excellent and gentle soap-based facial cleanser is rose hip seed oil.
