Clarins Cleansing Milk with Alpine Herbs is a makeup-remover and cleanser for normal or dry skin that is said to gently cleanse while hydrating and softening. One of the key ingredients in this cleansing milk is alpha-glucan oligosaccharide, a prebiotic. Prebiotics are a type of non-digestible fiber compound that provide indirect benefits by enhancing the growth or activity of beneficial microorganisms that make up the skin’s microbiome. Ultimately, this results in healthier looking skin. Besides alpha-glucan oligosaccharide, Clarins Cleansing Milk with Alpine Herbs contains a handful of emollients and humectants that should help to moisturize and soften the skin. However, this formula contains many different synthetic fragrance ingredients, including parfum/fragrance, limonene, linalool, hydroxycitronellal, alpha-isomethyl ionone, benzyl salicylate, eugenol, amyl cinnamal, and many more. All of these ingredients have the potential to cause allergic reactions and/or skin irritation.Plus, you don’t always need to immediately see or feel the sensitizing effects of fragrance ingredients for your skin to suffer damage. Unfortunately, all of these fragrance ingredients are used in higher concentrations than most of the beneficial ingredients in the Clarins Cleansing Milk with Alpine Herbs, so this product may cause more harm than good.
