In short, all the pH advocates have is a little basic science, a lot of speculation, and some folklore. The stratum corneums role as a permeability barrier hinges on its hydrophobic character, lipid distribution, and organization of lipids into a series of lamellar bilayers (24). 5 Steps to Correct Your Skin pH Balance. Similarly, blockade or knockout of secretory phosholipase A2 or the sodium-proton exchanger, both of which are involved in acidification of the SC, resulted in compromised permeability barrier homeostasis and SC integrity (2, 3). Male skin is, on average, approximately 20% thicker than female skin. Additionally, key enzymes involved in the synthesis of the permeability barrier, -glucocerebrosidase and acidic sphingomyelinase, which require an acidic pH are not fully activated in the newborn period resulting in decreased skin hydration (17).

Use of AHA in irritant dermatitis appears useful as evident by reduction in sensitivity to SLS. Acidification of SC alone substantially prevents development of barrier abnormalities and downstream immune abnormalities during the elicitation phase of murine AD, providing direct evidence for the "outside-inside" pathogenesis of AD and suggesting that maintenance of an acidic SC pH could prevent the emergence of AD in humans. Ceramide deficiency, observed in aged skin (20) has implications for barrier function and may be explained by elevated activity levels of certain enzymes that have alkaline optima.

Lowering pH in these hapten exposed mice also reduced the inflammatory TH2 response, prevented epidermal hyperplasia, reduced tissue eosinophilia, and normalized epidermal structure (29). AHA, such as lactic acid have been shown to increase ceramide production by human keratinocytes by 300% in vitro (86). Findings suggest that changes in the pH and the organic factors influencing it appear to play a role, not only in the pathogenesis, prevention and treatment of irritant contact dermatitis, but also of atopic dermatitis and ichthyosis and in wound healing. A number of factors play a role in development of irritant diaper dermatitis, including prolonged exposure to urine and feces, increased hydration and occlusion, changes in skin microbial flora, and altered skin pH (64). Enzymes involved in desquamation are pH-dependent and alteration in pH disturbs normal desquamation (57). It's What Goes On Beneath the Surface of Your Skin That Counts Normal Healthy Skin Barrier In normal skin, the skin barrier prevents excess water loss and prevents invasion by micro-organisms/allergens and chemicals Use of soap with high pH causes an increase in skin pH, which in turn causes an increase in dehydrative effect, irritability and alteration in bacterial flora. Factors influencing skin pH (adopted from Yosipovitch et al. Hair removal. Others have documented similar findings of sequentially rising pH values in unaffected skin compared to perilesional skin and lesional skin in atopic patients (43, 44).
