The skin offers an attractive way for dermal and transdermal drug delivery that is why the drug still needs certain qualities to transcend the outermost layer of the skin, the stratum corneum. The requirements are: drugs with a maximum molecular weight of 1kDa, high lipophilicity and a certain polarity. This would restrict the use of a transdermal delivery of macromolecules, which would make the drug more effective in therapeutic administration. Various studies have shown that macromolecules without support do not penetrate the human skin...

Papular acne scars are skin-colored or hypopigmented, soft and elevated lesions of the chin and trunk. Papular scars are one of the most difficult acne scars to treat. Herein, we reported two patients with papular acne scars on the chin that were successfully treated by the pinhole method using an Erbium (ER):YAG laser. Good cosmetic results were achieved in both patients. The side effects included mild, intra-, and post-procedural pain and erythema that resolved spontaneously within 2 weeks. The pinhole method with an Er:YAG laser could potentially be used as a safe and effective treatment for papular acne scars...

Despite being a ubiquitous animal pain model, the natural TRPA1-agonist allyl-isothiocyanate (AITC, also known as "mustard oil") has only been sparsely investigated as a potential human surrogate model of pain, sensitization, and neurogenic inflammation. Its dose-response as an algogenic, sensitizing irritant remains to be elucidated in human skin. Three concentrations of AITC (10%, 50%, 90%) and vehicle (paraffin) were applied for 5 min to 3x3 cm areas on the volar forearms in 14 healthy volunteers, and evoked pain intensity (visual analog scale 0-100 mm) and pain quality were assessed...

Chemical enhancers are widely used to facilitate drug permeation in transdermal drug delivery system (TDDS) and the effect of chemical enhancers is desired to be temporary. Though temporary enhancement effect of chemical enhancers has been widely discussed, there is still a lack of knowledge about the molecular mechanism of temporary enhancement effect. Using the skin permeation of flurbiprofen as a probe, the temporary enhancement effect of isopulegol decanoate (ISO-10) was evaluated with in vitro permeation experiment and confocal laser scanning microscopy (CLSM)...

Transdermal protein delivery is a useful and attractive method for protein therapy and dermal vaccination. However, this delivery method is restricted by the low permeability of the stratum corneum. The purpose of this study was to develop a transdermal delivery system for enhancement of protein permeability into the skin. First, we prepared a transparent gel patch made of polysaccharides with gold nanorods on the gel surface and fluorescein isothiocyanate-modified ovalbumin (FITC-OVA) inside. Next, the gel patch was placed on mouse skin to allow contact with the coated gold nanorods, and irradiated by a continuous-wave laser...

BACKGROUND AND OBJECTIVE: Port wine stains (PWS) are congenital vascular malformations that progressively darken and thicken with age. Laser therapy is currently the most effective way in clinical practice for PWS. A 1,064 nm Nd:YAG laser in the near-infrared band can achieve a deeper treatment depth compared to the current widely adopted pulsed dye laser. However, because of its relatively weak absorption by blood, single-pulse Nd:YAG laser requires high energy density to cause effective vessel damage, but may inflict undesirable burning to surrounding collagen...

Studies indicate that hyperthermic therapy using gold nanorods and photodynamic activity with many photosensitizers can present a synergistic effect, and offer a great therapeutic potential, although more investigation needs to be performed before such approach could be implemented. We proposed to investigate the effect of the attachment of phthalocyanines on the surface of gold nanorods (well-characterized devices for hyperthermia generation) for the elimination of melanoma, one of the most important skin cancers due to its high lethality...
