Background: Fighting skin aging signs is one of the major challenges of the 21st century, recently, mesenchymal stem cells (MSCs) and microneedling (MN) have been applied for anti-aging. This study aims to evaluate the efficacy of the combination of MN and human umbilical cord-derived mesenchymal stem cells conditioned media (hUC-MSCs-CM) in skin brightness and rejuvenation.
Methods: Thirty volunteers with facial skin aging were recruited for the randomized, controlled split-face study. The left and right sides of the face were randomly applied with saline MN or hUC-MSCs-CM MN. Five sessions were performed for each volunteer at 2-week intervals. Two dermatologists evaluated the clinical improvement, in terms of skin brightness and texture. A satisfaction score based on a self-evaluation questionnaire was recorded at 2 weeks after the last treatment. The objective evaluation was recorded before the first treatment, and at 2 weeks after the last treatment.
Results: Twenty-eight volunteers with a mean (SD) age of 41 (6.54) years old completed the trial. The investigator's assessment for skin brightness and texture, and the self-satisfaction score revealed statistically better effects in hUC-MSCs-CM -plus-MN group than in MN alone (MN saline) group. No severe side effects were reported during the whole study period. Compared to MN alone group, the objective assessment revealed significant improvements in skin brightness (reduced melanin index, ultraviolet spots, and brown spots) and skin texture (reduced wrinkles and pores, and increased skin elasticity) in hUC-MSCs-CM-plus-MN group, while there were no obvious differences in skin hydration, epidermal water loss, and the erythema index.
Conclusion: The combination of hUC-MSCs-CM and MN exhibite anti-aging efficacy, and this could be used for facial rejuvenation in the future.

Visible light has been considered to have minimal impact on the skin. However, the increasing use of electronic devices has led to a significant increase in exposure to visible light, especially blue light. We measured the irradiance (mW/cm) and estimated dose (J/cm) of visible light and blue light emitted from various electronic devices including smartphones, tablets and computers.

Imaginal exposure is a standard procedure of cognitive behavioral therapy for the treatment of anxiety and panic disorders. It is often used when in vivo exposure is not possible, too stressful for patients, or would be too expensive. The Bio-Informational Theory implies that imaginal exposure is effective because of the perceptual proximity of mental imagery to real events, whereas empirical findings suggest that propositional thought of fear stimuli (i.

Background: Intradermal injection of CPM-HA20G, a low-viscoelasticity hyaluronic acid (HA) dermal filler with glycerol, has been shown to be effective for facial rejuvenation in Caucasians, but research in Asians is limited.
Aims: This study aimed to evaluate the effectiveness and safety of CPM-HA20G in enhancing facial skin quality in Korean women using a protocol developed by local aesthetic experts.
Patients/methods: In this 24-week prospective, single-arm, open-label study, 20 women received CPM-HA20G injections in the immediate subdermal layer on the anterior cheek (1 mL per side; total 2 mL) in three sessions every 4 weeks.

This study aimed to develop in vivo methods for assessing facial anti-glycation and anti-aging effects and to investigate the link between glycation and aging signs. We utilized an AGE reader to measure AGEs levels on the face and arms, establishing a correlation to validate the reader's use for facial AGEs detection. Then the product's 7-day anti-glycation effect was evaluated.

It is characterized by the sudden onset of asymptomatic small erythematous hemangioma-like papules encircled by a pale halo. The precise pathogenesis is unknown; however, multiple environmental triggers have been reported.
