Visualization and quantification of the skin microvasculature are important for studying the health of the human microcirculation. We correlated structural and pathophysiological changes of the dermal capillary-level microvasculature with age and blo

Background and objectives A recent generation of 5,500 nm wavelength carbon monoxide (CO) lasers could serve as a novel tool for applications in medicine and surgery. At this wavelength, the optical penetration depth is about three times higher than

Background/objectives Standard optical coherence tomography angiography (OCTA) has been limited to imaging blood vessels actively undergoing perfusion, providing a temporary picture of surface microvasculature. Capillary perfusion in the skin is dyna

The limited per-pixel bandwidth of most microscopy methods requires compromises between field of view, sampling density and imaging speed. This limitation constrains studies involving complex motion or fast cellular signaling, and presents a major bo

Intrinsic and extrinsic aging of human skin induces significant morphological changes to its surface. The most prominent and important feature in cosmetics and dermatology is the alteration of the wrinkles. Roughness parameters (Ra, Rmax) described b

Optical coherence tomography angiography (OCTA) provides in-vivo images of microvasculature. In skin it often represents a dynamic perfusion state without depicting the actual extent of the vascular network. Here, we present the capillary refill meth

BACKGROUND Traditionally, fractional laser treatments are performed with focused laser sources operating at a fixed wavelength. Using a tunable laser in the mid-infrared wavelength range, wavelength-dependent absorption properties on the ablation pro

Cryolipolysis has become a popular non-invasive method of reducing excess fat by cooling. However, the results vary as metabolism, gender and diet may affect the freezing point of human subcutaneous fat. To increase the success for all patients, it i

Cutaneous nerve endings are assumed to change due to dermatological pathologies, such as psoriasis. Tan et al. (2019) present a method to assess changes in nerve architecture more precisely by using 3-dimensional histology. This commentary discusses

While optical coherence tomography (OCT) provides a resolution down to 1 micrometer it has difficulties to visualize cellular structures due to a lack of scattering contrast. By evaluating signal fluctuations, a significant contrast enhancement was d
