Professor Dae Hun Suh's research lab focuses on the pathophysiology of inflammatory skin disorders, particularly acne and hidradenitis suppurativa, with an emphasis on the roles of chronic inflammation, growth factors like TGF-β1, and extracellular matrix remodeling in scar formation. The lab investigates novel therapeutic approaches, including fractional CO₂ laser and platelet-rich plasma (PRP) therapy, to modulate fibrogenic responses and improve clinical outcomes. Additionally, the lab explores cultural influences on physician empathy through validated psychological assessments, highlighting cross-cultural differences in medical education and patient care. Their work bridges dermatology, molecular biology, and clinical practice with a strong translational focus.

There are four central factors that contribute to acne physiopathology: the inflammatory response, colonization with Propionibacterium acnes, increased sebum production and hypercornification of the pilosebaceous duct. In addition, research in the areas of diet and nutrition, genetics and oxidative stress is also yielding some interesting insights into the development of acne. In this paper we review some of the most recent research and novel concepts revealed in this work, which has been publis
These results may provide a basis for understanding the pathogenesis of atrophic acne scarring. Reduction of excessive inflammation and TGF-β1 signalling in early acne lesions is expected to facilitate the protection of normal extracellular matrix metabolism and ultimately the prevention of atrophic scar formation. What's already known about this topic? The dermis of atrophic acne scars shows alteration of extracellular matrix components such as collagen fibres. Inflammation in acne lesions is a
Our findings provide evidence in support of reliability and construct validity of the Korean version of JSPE for assessing empathy among Korean physicians. The disparity between Korean physicians and physicians from other countries may be explained by differences in the culture of medical education and medical practice. It suggests an exploration of cross-cultural differences in physician empathy.
Taken together with human study results combined with the data from cell experiments we suggest that PRP treatment increased fibrogenetic molecules induced by fractional CO<sub>2</sub> laser, which have association with clinical effect.

This study presents the demographic features and clinical characteristics of acne sufferers in Korea. This large-scale analysis provides a useful overview of acne in Korea.
Hidradenitis suppurativa (HS) is a chronic, relapsing, inflammatory skin disorder. Although several epidemiological studies have been conducted in Western countries, such data regarding Asian populations are scarce. In this study, we sought to investigate the demographic and clinical features of HS in Korea. A total of 438 patients, diagnosed with HS from May 2007 to April 2017, were enrolled and the electronic medical record of each patient was reviewed. Male patients were predominant with a ma
Fractional microneedling radiofrequency treatment showed modest clinical and histologic improvement of rosacea, and it might be used as an alternative or in combination with other treatment methods.
The aims of this study were to investigate the effect of UVA and UVB on comedones and sebum secretion in acne patients. Thirteen acne patients were irradiated by UVA (starting from 20J/cm2 and increasing 10% every day) and UVB (starting from 2/3 MED and increasing 10% every day). IL-1alpha, IL-6, IL-1 receptor antagonist (IL-1ra), IL-10 and GM-CSF were measured by ELISA. Measurement of sebum level was also performed. Sebum level was increased in the first three days by UVA (18.4 --> 37.6 microg/
This combination method can be a viable option for Asian patients having Riehl's melanosis with high risk of post-inflammatory hyperpigmentation, maintaining low-dose laser irradiation.
At the precision of this qualitative study, our results do not provide any evidence that different phylotypes in the surface microflora might be important in triggering acne. However, type IA P. acnes and Peptostreptococcus species might be more closely associated with inflammatory acne lesions.
Porokeratosis is a genodermatosis characterized by abnormal epidermal keratinization with the histologic finding of cornoid lamella. To date, five clinical variants have been identified. However, the coexistence of these variants in a single patient has been described only rarely. We report a 5-year-old girl with the simultaneous occurrence of porokeratotic lesions in linear and disseminated patterns. Linear lesions were detected at birth and the disseminated lesions developed at the age of 3 ye
Ota's naevus is a fairly common pigmentary disorder in Asians. Recently, encouraging results in the treatment of Ota's naevus have been obtained, but most of these concerned the white skins of Caucasian patients. Our purpose was to examine the clinical features of Ota's naevus in Koreans and to assess the clinical outcomes and histological changes induced by a Q-switched alexandrite laser at 755 nm. Eighty-seven Koreans with Ota's naevus were studied; the peak age of onset was during the first d
