Professor Hyung-Min Kwon's research lab focuses on translational biomedical research with a strong emphasis on regenerative medicine, metabolic syndrome, and cerebrovascular health. The lab investigates cell-free therapeutic strategies using adipose-derived exosomes for skin regeneration and aesthetic applications, while also exploring the role of metabolic markers—such as homocysteine, insulin resistance (TyG index), and glycaemic load—in neurological and dermatological conditions. Key research directions include the clinical application of stem cell-derived exosomes for acne scar treatment and the identification of metabolic risk factors for silent brain infarcts and cerebral small vessel disease in otherwise healthy individuals.

A variety of applications of human adipose tissue stem cell-derived exosomes have been suggested as novel cell-free therapeutic strategies in the regenerative and aesthetic medical fields. This study evaluated the clinical efficacy and safety of adipose tissue stem cell-derived exosomes as an adjuvant therapy after application of fractional CO2 laser for acne scars. A 12-week prospective, double-blind, randomized, split-face trial was performed. A total of 25 patients received 3 consecutive trea
Patients with acute stroke with elevated serum homocysteine levels are at an increased risk for END.
Recent studies have suggested that dietary factors, specifically glycaemic load, may be involved in the pathogenesis of acne. The aim of this study was to determine the clinical and histological effects on acne lesions of a low glycaemic load diet. A total of 32 patients with mild to moderate acne were randomly assigned to either a low glycaemic load diet or a control group diet, and completed a 10-week, parallel dietary intervention trial. Results indicate successful lowering of the glycaemic l
MetS was found to be significantly associated with SBI. This finding has clinical utility in terms of identifying healthy people at increased risk of developing SBI.
A high TyG index was associated with a higher prevalence and burden of cSVD in a neurologically healthy population. This marker of IR could be a convenient and useful predictor of cSVD.

An optimized therapeutic regimen involving a non-ablative fractionated laser or radiofrequency therapy for acne scars has not yet been established. To evaluate whether the combination of a non-ablative fractional laser (NAF) and fractional micro-needling radiofrequency (FMR) has clinical advantages for the treatment of atrophic acne scars compared with NAF alone, a 16-week prospective, randomized split-face study was performed. Each facial side of a patient was treated with 3 sessions of either
Cerebral SVD is associated with recurrent stroke in patients with LAA. Additionally, it may affect any mechanisms of recurrent stroke and even with a dose response manner.
Ectasia of the BA other than elongation or angulation appears to contribute to the occurrence of PPI. These findings may be helpful in predicting certain types of stroke.
Awareness of stroke, depression, and BP was enhanced when using the smartphone-based mHealth system. Emerging mHealth techniques have potential as new nonpharmacological secondary prevention methods because of their ubiquitous access, near real-time responsiveness, and comparatively lower cost.
