Research on local acidity and tissue repair

This edited account distinguishes personal experience, laboratory research and clinical studies. Individual suitability requires clinical assessment.

These notes consider pH in fibroblast and wound environments. Cell cultures, animal wounds and human skin differ, so they cannot be reduced to one optimal acidity.

The source brings together extracellular-pH and collagen-degradation material, acidic wound experiments and growth-factor research. The figure’s 6.4, 7.4 and 8.4 comparison must also be distinguished from the text’s 5.5–6.0 discussion against original data.

Different responses under experimental conditions do not establish that acidifying any skin improves healing. Surface pH and deeper local conditions after injection are not equivalent.

Basic research is not used as direct evidence of clinical regeneration after CaHA. Study populations, pH and methods need further review. The account provides no instructions for applying or injecting acidic substances.
