The NCP/mm² is a reproducible parameter for characterizing the skin surface topography. It is proposed as an additional parameter in dermatological research and practice because it represents distinct aspects of the cutaneous profile not covered by established roughness parameters.

Both measurement technologies provide reliable estimates indicating that skin surface measures of the volar forearm in young adults can differentiate between skin areas of different persons or different treatments in clinical studies. Skin surface topography of the volar forearm is comparable from distal to proximal assuring baseline comparability after randomization in clinical trials. SELS and PRIMOS roughness parameters of the volar forearm are not comparable and contain different types of information.

Background: Dry skin reflects a skin barrier defect which can lead to atopic dermatitis. Little is known about the distinct effects of emollient use in children with dry skin and atopic predisposition. Objectives: We investigated the effects of daily application of pressed ice plant juice (PIPJ)-based emollients and petrolatum-based emollients. Methods: Children aged 2-6 years with dry skin and atopic predisposition were randomized into 2 groups: group 1 received emollients containing PIPJ and natural lipids, while group 2 received petrolatum-based emollients. Skin condition and biophysical properties of the skin barrier were assessed at inclusion and weeks 4, 12 and 16. Results: Skin condition improved significantly in all children. Comparing the groups, children treated with emollients containing PIPJ showed significantly higher stratum corneum hydration values and significantly lower transepidermal water loss values at week 16 on the forearm and forehead. A significant decrease in skin pH was noted in group 2 on the forearm and forehead; group 1 showed a stable course. Conclusion: Early intervention with emollients in children with dry skin condition and atopic predisposition may improve their skin condition during daily emollient application. PIPJ-based formulations may be helpful to maintain skin barrier integrity.

The Visioscan® parameters SEr, Rmax, and Rz showed most reliable and valid values and were largely comparable on contralateral forearm skin sites in elderly subjects. Rmax, Rz, and Ra should be preferred for measuring skin surface topography with PRIMOS.

Background: Dry skin is a common skin condition in childhood. Few studies exist investigating the influence of daily skin care on dry skin in infants at risk of developing atopic dermatitis (AD). We aimed to assess the effect of skin care on dry skin in this special cohort using validated scores for AD and analysis of skin microtopography. Methods: 43 children were randomized to group 1 (G1) and group 2 (G2) and 22 infants to group 3 (G3). During 16 weeks, G1 and G3 applied daily a plant-based emollient and G2 a petrolatum-based emollient. The core outcome was assessed by Severity Scoring of Atopic Dermatitis (SCORAD) and Patient-Oriented SCORing Atopic Dermatitis (PO-SCORAD). The influence on the parents' life was evaluated by a questionnaire and microtopography by Visioscan® VC 98. Results: The SCORAD index declined significantly until week (W) 16 in all groups (p ≤ 0.041). The sleeplessness score analyzed by PO-SCORAD was highly reduced after W12 in G1 and after W16 in G2 (p ≤ 0.030). The influence on the parents' anxiety was reduced in G3 at W12 and W16 (p = 0.016). The Visioscan parameter scaliness strongly diminished at W4 (p ≤ 0.049) and W16 (p ≤ 0.013) in all groups. Conclusions: This trial demonstrates improved skin conditions and sleep following daily emollient application in infants and children having dry skin and being at risk of AD. Especially parents of infants showed a reduced fear that their children might develop AD. Further studies are required to investigate the preventive effect of daily emollient therapy in this special cohort evaluating the outcome measures used in this trial.

BackgroundDry skin and the associated impaired epidermal barrier function are postulated to constitute a major element in the development of atopic dermatitis.ObjectiveThe aim of this study was to evaluate the effect of two plant-based formulations on the epidermal barrier function in a defined cohort of infants with a predisposition for atopic dermatitis.MethodsOver a period of 16 weeks, 25 infants who were ages 3 to 12 months and had an atopic predisposition and dry skin received two emollients that contained pressed juice of the ice plant. The infants received both cream and lotion on the forearm, only cream on the face, and only lotion on the leg. Stratum corneum hydration (SCH), transepidermal water loss (TEWL), skin surface pH, and sebum were assessed on the infants’ forehead, leg, and forearm. The Scoring Atopic Dermatitis (SCORAD) index was used for the clinical assessment.ResultsSCH significantly increased in all body regions that were assessed. The forearm and leg revealed stable levels of pH and TEWL, but a decline in pH (week 16) and TEWL (week 4) was noted on the forehead. At week 16, sebum levels were lower on the forehead compared with those at baseline. SCORAD scores improved significantly during the study.ConclusionA daily application of both emollients was associated with increased SCH levels and a stable course of TEWL, pH, and sebum on the forehead except for the forehead when compared with the forearm and leg. Clinically, improved SCORAD scores were noted.
