Summary
Protective body washing significantly improves skin texture by narrowing the sulcus cutis interval and increasing equilateral triangle counts. This method leads to finer, more even skin, suggesting its utility for skin health.
Area of Science:
- Dermatology
- Skin Physiology
- Cosmetic Science
Background:
- Skin texture is a key indicator of skin health and appearance.
- Understanding the impact of cleansing methods on skin is crucial for effective skincare.
- Existing research lacks detailed analysis of how specific washing techniques affect micro-level skin topography.
Purpose of the Study:
- To investigate the differential effects of protective versus non-protective body washing methods on skin texture.
- To quantitatively assess changes in skin topography, specifically the sulcus cutis, following different washing protocols.
Main Methods:
- A 4-week controlled study involving nine healthy women in their 20s.
- Daily washing of forearms: protective method (right) vs. non-protective method (left).
- Quantitative analysis of digitized skin images, measuring sulcus cutis interval, thickness variance, and counting equilateral triangles.
Main Results:
- Protective washing resulted in significantly narrower sulcus cutis intervals from week 1.
- A significant increase in equilateral triangle counts was observed with protective washing at weeks 1, 2, and 4.
- While mean sulcus cutis thickness showed no significant difference, interval and triangle counts indicated a finer skin texture with protective washing.
Conclusions:
- Protective washing effectively promotes a more even and finer skin texture.
- The number of equilateral triangles, as quantified in this study, serves as a potentially valuable index for assessing skin texture quality.

The pre-procedure steps of handwashing include removing jewelry and rolling up sleeves. However, many organizations allow staff to wear wedding rings.
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury. The nails must be short and clean, without nail...

01:27The Skin Microbiota
123
The human skin serves as a complex ecosystem inhabited by a diverse community of microorganisms, including bacteria, fungi, and viruses. This microbiome plays a critical role in maintaining skin health and defending against pathogenic invaders. The composition of microbial communities varies significantly across different regions of the body, influenced primarily by the local levels of moisture and sebum.Regional Variation in Skin MicrobiotaCutibacterium acnes predominantly colonizes sebaceous...

01:25Shape and Texture of Coarse Aggregate
1.3K
Aggregate shape is classified based on the relative sharpness or roundness of the edges and corners. This classification includes categories like rounded, angular, elongated, and flaky, each with specific characteristics. Rounded aggregates, fully shaped by attrition, are typical of river or seashore gravel, while angular aggregates, such as crushed rock, have well-defined edges. Aggregates that are elongated and flaky are less desirable, as they can reduce the workability and strength of...

01:21Characteristics of Dry Friction
1.2K
Dry friction occurs when two solid surfaces slide against each other without any lubrication or fluid present. It causes resistance when pushing objects along a surface, like a gardener pushing a wheelbarrow. The force applied to move the cart causes dry friction between the wheel and the ground.
Before the wheelbarrow starts moving, the static frictional force acts tangentially to the contact surface, opposing the force that is about to induce the motion. This frictional force prevents the...

Handwashing is hand hygiene with plain or antimicrobial soap and water to physically remove dirt, organic material, and microorganisms. However, it may not kill all microorganisms. The handwashing procedure requires a hand wash basin, liquid soap, paper towels, a domestic waste bin, and disposable nail cleaner as optional equipment.
Hand wash basins in clinical areas should have faucets that can be turned on and off without using the hands; that is, they should be non-touch or lever-operated....
