Ideally, skin should feel soft and smooth; more importantly however we need our skin to protect us from UV damage, free radicals and hazardous microorganisms while simultaneously providing barrier protection from various chemicals and liquids. The epidermis is actually part of our innate immune system and serves as one of the body’s primary defense mechanisms to protect us from an onslaught of environmental stimuli. Yet the ability of the epidermis to fulfill all of these functions tends to diminish if it is not properly hydrated, so the way we like our skin to look and feel is also optimal for its function. AC Moisture-Plex Advanced PF is formulated to address all of these issues by improving barrier integrity, reducing evaporation, improving moisture balance (with 24 hour moisturization efficacy), and maintaining lipid balance all while increasing cellular renewal. There are a multitude of ways for our skin to become dry, which results in irritation, damage and loss of function. We have to worry about more than just cold temperatures, changes in humidity and the wind drying out our skin, and often the products we use can cause the same drying effect. Soap, facial cleansers and toners are notorious for dehydrating our skin, and ironically due to the alcohol content, some moisturizers can actually cause the same effect. The epidermis consists of several layers with the outermost layers being keratinized cells held together by epidermal lipids. Secreted on the surface is a layer of sebum that provides moisturizing benefits. When the skin becomes dry, the layer of sebum is often stripped away, and the integrity of the epidermal lipids is less substantive. The keratinized cells separate and the skin becomes itchy and usually appears red, inflamed and cracked. With a plethora of efficacy supporting moisturization, enhanced barrier protection, and increased cellular renewal AC Moisture-Plex Advanced PF is an ideal ingredient for personal care products marketed toward protecting the skin for optimal function.
