Summary
Physician-created TikTok videos about atopic dermatitis (AD) receive positive engagement. Comments reveal users sharing experiences and seeking advice, highlighting a need for more content on darker skin tones.
Area of Science:
- Dermatology and social media analysis
- Digital health communication
- Patient engagement in online health communities
Background:
- TikTok is a rapidly growing platform for health information, including atopic dermatitis (AD).
- Previous research on TikTok health content often focuses on information credibility.
- Limited studies examine physician-created videos and audience interaction regarding AD.
Purpose of the Study:
- To analyze audience responses to board-certified dermatologists' TikTok content on AD.
- To understand user interactions within the comment sections of these videos.
Main Methods:
- Searched TikTok for "atopic dermatitis" and "eczema" videos by board-certified dermatologists.
- Analyzed 28 videos categorized as disease explanation, recommendation, misinformation debunking, or informal.
- Classified top 50 comments and replies per video into predefined interaction categories.
Main Results:
- Video category did not significantly affect engagement rates.
- Personal experience and information-sharing comments were more prevalent than critical or off-topic ones.
- Negative personal experiences were commented more frequently than positive ones; replies often offered recommendations and emotional support.
Conclusions:
- Dermatologist-produced TikTok content on AD is generally well-received across different video styles.
- Comment sections foster supportive environments for users to share experiences and recommendations.
- There is an identified gap in dermatologist-created TikTok content addressing atopic dermatitis on darker skin tones.

01:23Skin Diseases and Disorders
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.

01:19Clinical Applications of Epidermal Stem Cells
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...
01:15Reticular Dermis
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.

Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

01:11Papillary Dermis
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...

01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

01:14Changes in Skin Color: Clinical Perspectives
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
