    Dermatology 3.0: New Technologies Transforming the Management of Skin Conditions
    (2025) Tan, Jerry; Jean‐Aan Koh, Mark; Navarrete Dechent, Cristian
    Integration of digital technologies in dermatology is revolutionising patient care by increasing accessibility, accuracy and personalisation. This review explores the impact of emerging digital technologies in dermatology, including teledermatology, artificial intelligence (AI), mobile applications, wearable devices and 3D imaging and printing. Teledermatology, using real-time videoconferencing and store-and-forward imaging, has expanded since the COVID-19 pandemic, improving access to dermatologic care in underserved areas. AI-powered algorithms are being increasingly used, particularly in skin cancer detection, by helping clinicians make faster and more accurate diagnosis and treatment decisions in diverse clinical settings. AI is also improving clinical workflows, increasing automation and reducing documentation burden. Mobile health applications, including AI-based tools, are transforming patient self-management and monitoring. Wearable devices enable continuous monitoring of skin health and environmental factors, providing real-time insights into conditions like atopic dermatitis and melanoma. In addition, advances in 3D imaging and printing technologies are enabling for more precise grafts and early detection of skin cancer, leading to improved clinical outcomes. Despite these advancements, significant challenges remain, including automation bias, the need for standardised validation protocols and equitable access across diverse populations. Successful integration of these technologies into clinical practice will require addressing these issues and ensuring data security, improved digital literacy and clear guidelines for their use. Future research should focus on assessing the real-world effectiveness of these technologies and ensuring their equitable use in diverse geographies and patient populations.

    Evaluation of Ultrasound Changes With the Use of Microneedling Versus Fractional CO2 Laser in Atrophic Acne Scars
    (2024) Nanco-Melendez, Claudio; Yagnam-Diaz, Mathias; Munoz-Caceres, Marco; Contador-Gonzalez, Javier; Gubelin-Harcha, Walter; Chicao-Carmona, Fernando; Tan, Jerry; Wortsman, Ximena
    Introduction: Atrophic acne scarring, a common sequela of acne, can be treated by different interventions, including microneedling and laser resurfacing. Objectives: We sought to evaluate the comparative efficacy of microneedling versus fractional CO2 laser in treating atrophic acne facial scars using imaging with high and ultra-high frequency ultrasound. Methods: Participants received 2 sessions, separated by 1 month, of microneedling on the left side of the face and fractional CO2 laser on the right. Color Doppler ultrasound evaluations (24 and 70 MHz) were conducted at baseline and 3 months after treatment. Each patient completed questionnaires on satisfaction, pain, and adverse effects. Results: Nine subjects were enrolled. The frequency order of scar types was boxcar, ice-pick, and rolling. At 3 months, using the acne scar clinical evaluation scale, a decrease in scar scores of both methods was observed for total scars (P = 0.0005), ice-pick scars (P = 0.0128), and rolling scars (P = 0.0007). Twenty-two scars analyzed by ultrasound demonstrated a trend to decrease in size; however, no significant changes were observed for either microneedling or CO2 laser treatments. Moreover, there were no significant differences between these methods. Both treatments were rated as good or very good by patient assessments. There was a low frequency of pain and hyperpigmentation reported with both modalities, albeit somewhat higher with microneedling. Conclusions: Both microneedling and CO2 laser improved atrophic acne scars. Ultrasound did not show significant differences between these modalities.
