Natural PHAs are polyhydroxy acids that are present naturally within the body, specifically mentioned in skin cells, which include substances like gluconolactone (or gluconic acid) and galactose.
Polyhydroxy Acids (PHAs) are a group of chemical compounds known for their exfoliating and skin-conditioning properties, often used in skincare. When described as "natural PHA," the term refers to these types of acids that occur organically within biological systems, as highlighted by the presence of certain PHAs naturally found in human skin cells.
Examples of Natural PHAs in Skin Cells
Based on the provided information, two key examples of PHAs naturally present in skin cells are:
- Gluconolactone or Gluconic Acid: This substance is described as a naturally occurring PHA and an effective antioxidant. Its primary role mentioned is to combat inflammation, suggesting protective and soothing benefits for the skin.
- Galactose: Also noted as being naturally present in the body, galactose is highlighted for its function in stimulating collagen production. Collagen is a vital protein for skin structure and elasticity, so stimulating its production contributes to maintaining skin firmness and reducing signs of aging.
These naturally occurring PHAs contribute to the skin's inherent functions, such as defense against damage (antioxidant, anti-inflammatory) and maintaining structural integrity (collagen stimulation).
