Night Relaxing Facial Cleanser

The base most products are built on. It carries the other ingredients and has no safety concern.

A common foaming cleanser, milder than SLS. Fine for most people in a rinse-off product.

A humectant that draws water into the skin. One of the best-studied, best-tolerated ingredients in personal care.

A synthetic polymer used to thicken and stabilize cosmetic formulas. The polymer chains are too large to penetrate skin; graded safe by the Cosmetic Ingredient Review and widely used in rinse-off and leave-on products.

A coconut-derived amphoteric surfactant used to boost foam and mildness in cleansers and shampoos. CIR has reviewed it as safe as used, but it is one of the more established contact-allergy triggers in personal care, usually traced to manufacturing impurities such as amidoamine and dimethylaminopropylamine (DMAPA) rather than the betaine itself. People with a history of eyelid or scalp dermatitis are more likely to react.

A widely used preservative, safe at the legal limit of 1% or less. Often the "paraben-free" replacement.

Caprylyl glycol is a plant-derived humectant that also has mild antimicrobial properties, so it is commonly paired with other preservatives to allow lower overall preservative levels. Available data do not point to meaningful irritation or sensitization concerns at typical use levels.

A strong alkali used in tiny amounts to adjust the pH of cosmetics to safe, skin-friendly levels. At the pH found in finished products, sodium hydroxide is neutralized and well tolerated.

An undisclosed scent blend that can contain dozens of components. The single most common cause of cosmetic contact allergy, and the blend is not itemized, so you cannot see what is in it.

A chelating agent that binds trace metal ions to keep formulas stable and preservatives working properly. It is not a functional skincare "active" and only a very small amount is used, with minimal skin penetration expected.

Used in tiny amounts to set a product to skin-friendly pH. No concern at those levels.

A preservative that keeps products free of mold and bacteria. Reviewed repeatedly and considered safe at the low levels used.

A member of the paraben family used to prevent microbial growth in cosmetics. Like methylparaben, it has been reviewed extensively and found safe at the concentrations used in leave-on and rinse-off products.
