Fruit Acid is from fruit! 

Malic acid plays a key part in the metabolism of carbohydrates as well as the formation of
. It is a fruit acid that is synthesized as part of the Kreb's (citric acid) cycle in human metabolism. This is used to produce energy from the burning of pyruvic acid, without the associated buildup of lactic acid.

Alpha-hydroxy acids are commonly found and isolated from fruits of all sorts. That is why they are referred to as fruit acids. For example, malic acid is found in apples, citric acid can be isolated from most all citrus fruits and glycolic acid is commonly found in honey or sugar cane. Another source of AHAs is from the fermentation of natural products. Lactic acid is found in milk that has soured, and tartaric acid can be isolated from fermented grapes (wine). All are used as an ingredient for improving the condition of skin.

Glycolic Acid is the most commonly used AHA. Because of its small molecular weight and size, it is presumed to have a better capacity to penetrate skin. Lactic acid on the other hand, has a larger molecular weight than glycolic acid but is capable of being converted in vivo to pyruvic acid (an alpha keto acid), which is presumed to be a more effective exfoliating agent.

Today, alpha-hydroxy acids are used extensively in cosmetic dermatology (1). At concentrations lower than 10%, they are regularly formulated into everyday use creams. At these levels, skin benefits result from continuous use and result in a gradual reduction in fine lines and an overall improvement in skin texture brought about by accelerated desquamation (exfoliation). At higher concentrations they act as peeling agents.

When applied to the skin, these hydrated AHAs act to increase the water content of the skin and thus moisturize the outer layer of the epidermis (the stratum corneum) and consequently make the skin softer and more flexible. The second method by which AHAs are thought to act is by reducing corneocyte adhesion and accelerating cell proliferation within the deeper basal layer of the skin (layers 4,5,6). This exfoliating action of AHAs occurs as a result of their ability to break the bonds between dead skin cells that form at the surface of the skin. Skin normally has a dead layer of cells at its surface (the corneocyte layer), and AHAs can speed up the normal process of skin cell regeneration and sloughing.

Long term UV radiation exposure also degrades collagen in the dermis layer of the skin. There is evidence that excessive amounts of abnormal elastic fibers also tend to accumulate within the dermis of photo-damaged skin. Glycolic acid at low concentrations works well to decrease corneocyte cohesion by promoting exfoliation of the outer layers of the stratum corneum. This is especially relevant since most pigmentation alterations associated with photo-damage can be attributed to the thickening of the stratum corneum and the accelerated skin regeneration and sloughing becomes even more necessary resulting in improvement of skin smoothness and in the appearance of lines and wrinkles.

All fruit acids increase cell renewal stimulation with increased concentration.  It must be recognized that it is the free acid form of the AHA molecule that is responsible for cell renewal stimulation.

Anti-Aging Clinic “Fruit Acid Gel 15%” Will enhance exfoliation; Fruit Acids (Glycolic Acids) are naturally occurring substances found in a variety of fruits, apples and sugar cane.  The Anti-Aging Clinic Fruit Acid Gel will help remove the outer layers of thickened or damaged skin.

Ingredients: Distilled Water, Olive Oil Castile, Glycolic Acid, Vegetable Glycerin, Rose Hip Seed Oil, Essential Oils, Seaweed Extracts.

Apply a few drops to the fingertips and massage into the skin.  Apply to the skin in a thin layer after cleansing with AHA 10% Cleanser. Rinse with tepid water for about 2 to 3 minutes and pat dry.  May be left on the skin for longer periods when tolerance is built up.  Avoid contact with eyes.
