Summary
Daily or less frequent bathing and consistent moisturizer application are linked to reduced atopic dermatitis (AD) severity. Showering duration did not impact AD outcomes in this study.
Area of Science:
- Dermatology
- Clinical Research
Background:
- Evidence-based guidelines for optimal bathing in atopic dermatitis (AD) are scarce.
- Understanding the relationship between bathing habits and AD severity is crucial for patient management.
Purpose of the Study:
- To investigate the longitudinal associations between showering/bathing practices and atopic dermatitis severity.
- To evaluate the impact of moisturizer application frequency on AD outcomes.
Main Methods:
- A prospective, single-center study involving dermatology outpatients with AD.
- Data collected on shower/bath frequency, duration, and post-bathing moisturizer application.
- AD severity assessed using multiple validated instruments (o-SCORAD, SCORAD-itch, EASI, POEM, DLQI).
Main Results:
- Bathing more than once daily correlated with increased AD severity scores (SCORAD-itch, o-SCORAD, EASI, POEM, DLQI).
- Consistent or inconsistent post-bathing moisturizer application was associated with lower AD severity (o-SCORAD, EASI, POEM).
- Shower/bath duration showed no significant association with AD severity outcomes.
Conclusions:
- Daily or less frequent bathing, combined with regular moisturizer use, is associated with improved AD control.
- Current recommendations on shower duration for AD patients may require re-evaluation.
- Adherence to bathing and moisturizing recommendations appears linked to overall AD severity.

01:21Accessory Structures of the Skin: Sebaceous Glands
2.0K
A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...
