What is micellar water? Get ready to work a whole new kind of cleanser into your routine. Micellar
water is the facial cleanser that has been the best-kept beauty secret in Europe for decades. Micellar water

particles found in micellar water, work to attract dirt and impurities and lift them from the surface of your
skin. Micellar water is extremely thorough and can remove a variety of makeup products including
everything from foundation to eye makeup and mascara. It also removes sweat and excess oil. Often, skin
care and makeup removal require two separate products. The best part about micellar water? It
incorporates both tasks into one easy to use product.

skin blemishes. As a response, skin care experts desperately looked for an alternative to Parisian city
water for cleansing needs. After developing micellar water, it quickly became a substitute to the harsh
water as it removed makeup, sweat, oil and dirt without the need to rinse. Micellar water has finally made
its way into the mainstream beauty market in the United States.
