L-Ascorbic Acid appears as a white crystalline powder which is soluble in water; as such, it is particularly unstable, rapidly deteriorating when exposed to oxygen or heat.

THE ACHIEVEMENT OF KIEHL’S CHEMISTS:
Kiehl’s chemists have stabilized a high concentration of pure Vitamin C – known as L-Ascorbic Acid. – by formulating it in a stabilizing base in the form of a line-reducing concentrate which helps skin recover from some of the more visible effects of skin aging.
In a double blind clinical study conducted by leading dermatologist, Dr. James Leyden, of the Skin Study Center, Kiehl’s Dermatologist Solutions Powerful-Strength Line-Reducing Concentrate showed superior results on skin against a potent Retinol treatment cream (0.075%).
After four weeks, and increasingly through a twelve-week period, the Kiehl’s Dermatologist Solutions formula was noted to diminish the appearance of:
Crows feet fine lines
Sub-orbital fine lines
Skin tone
Sallowness
The Kiehl’s Dermatologist Solutions formula showed superior results over Retinol (without the irritation or sensitivity often associated with Retinol use) in the overall appearance of the skin, including:
Skin texture (at four weeks)
Skin tone (at eight weeks)
Marionette lines extending from the mouth to the chin (at twelve weeks)
Glycerin is a by-product of soap manufacturing and is a clear, syrupy liquid, usually derived from vegetable oil and obtained by adding alkalies to fats and fixed oils. It is a solvent humectant and emollient in many skin care products, as it absorbs moisture from the air and thereby helps products retain their moisture. It improves the spreadability of products and has definite skin moisturizing benefits.
Propylene Glycol is a common moisture carrying ingredient in skin care. It acts as a humectant by absorbing water from the air. It penetrates the upper layers of the skin well and leaves a nice feel.
