GARDENA, Calif.—Marie Louise Cosmetics, a Japanese skin care brand since 1912, is now available to American estheticians and their clients. The line is based on the science of deep-sea minerals and nanotechnology to help skin achieve the balance it needs to appear healthy. Marie Louise Cosmetics skin care uses Deep Water Concentrate, a proprietary blend with deep-sea minerals essential to cellular metabolism, at the same time the water is desalted. In addition to Deep Water Concentrate, product formulas include vitamin C, alpha-arbutin, ceramides, hydrolyzed yeast, hyaluronic acid and other ingredients promoting skin health. Marie Louise’s nanoemulsion technology features a three-layer structure, which allows products to penetrate deeper and remain more stable.
