Healthy Aging (HA), Specialty Treatment (ST), Special Use (SU) and Eye Care (EC) products.  Note: abbreviations are located besides the size designation and above price for each product.  

HA- Healthy Aging products are our most technically advanced and most popular products for mature skin.  ST- Specialty Treatment products are those whose efficacy is excellent when used alone, but is further enhanced in combination with other items in our Beauty Basics and Skin Solutions Collections.  SU- Special Use products that alone provide a treatment or solution to a specific skin issue or concern.  EC- Eye Care are products designed especially for the eye zone.  Sun exposure, stress, the environment and time are the culprits of wrinkled and/or aged skin.  As we age, the epidermis stops producing and repairing skin cells as rapidly. This results in drier, thinner and more wrinkled skin, especially in the delicate tissues surrounding the eye.  It takes time to develop wrinkles and it takes time to gently reduce wrinkles.  Naturally assisting and stimulating cell renewal and collagen production makes the most sense in fighting issues surrounding mature skin.
