How does it work?
Alpha-hydroxy acids are naturally occurring acids. Lactic acid is derived from the fermentation of sour milk. This acid helps to dissolve the "glue" that holds the keratinized skin cells together and increases cell exfoliation and replacement. Lactic acid is a natural humectant, which holds water in the upper layers of the skin increasing the skins moisture.
Noted under Glycolic Acid:
Alpha-hydroxy acids are naturally occurring acids, derived from the sugars in particular plants. Some examples are Glycolic Acid (Sugar Cane), Lactic Acid (Milk & Corn), Tartaric Acid (Grapes), Citric Acid (Citrus Fruits), Malic Acid (Apples), and Mandelic Acid. These acids work at the very base of the stratum corneum, dissolving the cement that holds dead skin cells together. This increases cell turnover and influences the structure of new stratum corneum being made. This results in skin that is more flexible, more smooth, and more even in tone. At greater concentrations (12%-20%), deeper dermal effects, such as higher amounts of ucopolysaccharides and collagen and increased skin thickness, are observed. Eventually, alpha hydroxy acids will produce skin that is softer, smoother, less wrinkled, less dehydrated, and more even in skin tone.
Lactic Acid Toner [10% final strength]
Total End Product: 4 ounces 120 grams
Lactic Acid 88% 11.5% .46 oz 13.8 grams
Hyaluronic Acid 1% 50 % 2 oz 60 grams
Distilled water 38 % 1.52 oz 45.6 grams
Optiphen .5 % .02 oz .6 grams
Total 100% 100% 100%
Adjust the Ph of the final product with Baking Soda to between 2.5 and 3.5.
The math formula used for this is:
120 grams or 4 oz x 10% (final strength) divided by 88% (strength of acid) equals 13.8 grams or .46 ounce (these can be rounded to make formulating easier)
