SummaryThe skin surface pH on the forehead and cheek of 574 men and women aged 18–95 was measured. No differences were found between men and women regarding forehead and cheek pH distribution. The group over the age of 80 showed higher pH values on both the forehead and the cheek. In 89% of the subjects measured, the skin surface pH on the cheek was higher than that on the forehead. The central 90%, i.e., the “representative range”, for the population below the age of 80 is between 4.0–5.5 on… 
Comparison of sebum secretion, skin type, pH in humans with and without acne
TLDR
The objective skin types were significantly different than the subjective skin types in subjects with acne, whereas the two skin types did not differ in subjects without acne, and the relationship between pH and sebum secretion was analyzed in each population.
Age-Related Changes of Stratum Corneum Functions of Skin on the Trunk and the Limbs
TLDR
It is clarified that most of the SC functional parameters change with age on both the trunk and the limbs in a similar manner, suggesting that the limbs are acceptable sites to estimate the SC functions of the trunk of elderly patients.
Gender Difference of in vivo Skin Surface pH in the Axilla and the Effect of a Standardized Washing Procedure with Tap Water
TLDR
There is a gender difference in axillary skin surface pH between men and women with more acidic values in females, and washing with water further increased the difference between male and female pH values.
Impact of Age and Body Site on Adult Female Skin Surface pH
TLDR
Adult pHSS on the forehead, the temple and the volar forearm increases slightly with age, which is crucial for adapting medical skin care products.
Variation of Skin Surface pH, Sebum Content and Stratum Corneum Hydration with Age and Gender in a Large Chinese Population
TLDR
In a large Chinese cohort, the skin surface pH, sebum content and SC hydration vary with age, gender and body site.
Natural skin surface pH is on average below 5, which is beneficial for its resident flora
TLDR
Assessment of skin surface pH of the volar forearm before and after refraining from showering and cosmetic product application and the effect of pH on adhesion of resident skin microflora was assessed; an acid skin pH (4–4.5) keeps the resident bacterial flora attached to the skin, whereas an alkaline pH (8–9) promotes the dispersal from the skin.
Lipidomics analysis of facial skin surface lipids between forehead and cheek: Association between lipidome, TEWL, and pH
TLDR
There are few studies based on lipidomics at the molecular level focusing on the lipid profile variations of skin surface lipid (SSL) in forehead and cheek.
Functional analyses of the eyelid skin constituting the most soft and smooth area on the face: contribution of its remarkably large superficial corneocytes to effective water‐holding capacity of the stratum corneum
TLDR
The eyelid constitutes a unique area on the face because of its soft, smooth and thin skin distinct from that of other facial portions, which facilitates their easy compliance to blinking movement, which is indispensable to protect the wet surface of the eyeball.
Biophysical parameters of skin: map of human face, regional, and age‐related differences
The face showed anatomical variation on reaction to chemicals, which could be related to differences in biophysical specificities of the skin. The aim of this study was to establish a map of the face
Skin Surface pH and Topical Emollient: Fact or Artifact?
TLDR
The findings show that certain petrolatum-based emollients and components could create a protective barrier and help maintain the healthy acidity of the skin and provide new evidence of emollengers helping to stabilize skin pH in its natural balanced state rather than affecting it.

TLDR
The parameter "skin pH" depends mainly on the area of skin and on age, but it also depends to a lesser extent on sex, race and the time of day when values are determined.
Patterns of Skin pH From Birth Through Adolescence: With a Synopsis on Skin Growth
TLDR
This monograph on skin pH will serve a useful purpose since skin pH has not been thoroughly reviewed in recent years and the dermatologists will find little new in the authors' "synopsis on skin".

TLDR
The aim of the writer is to demonstrate the importance of the cutaneous reaction, that is, the acidit or alkalinity of the skin surface under a range of conditions, and to emphasize this idea a series of cases of infantile eczema has been studied.
