Abstract
Bimatoprost (BIM) is a prostaglandin F2α analogs originally approved for the treatment of glaucoma and ocular hypertension. Recent studies have highlighted its potential to boost hair growth. The objective of this investigation is to challenge the potential of spanlastics (SLs) as a surfactant-based vesicular system for promoting the cutaneous delivery of BIM for the management of alopecia. BIM-loaded spanlastics (BIM-SLs), composed of Span as the main vesicle component and Tween as the edge activator, were fabricated by ethanol injection method. The formulated BIM-SLs were optimized by 23 full factorial design. The optimized formula (F1) was characterized for entrapment efficiency, surface charge, vesicle size, and drug release after 12 h (Q12h). The optimized formula (F1) exhibited high drug entrapment efficiency (83.1 ± 2.1%), appropriate zeta potential (-19.9 ± 2.1 mV), Q12h of 71.3 ± 5.3%, and a vesicle size of 364.2 ± 15.8 nm, which favored their cutaneous accumulation. In addition, ex-vivo skin deposition studies revealed that entrapping BIM within spanlastic-based nanogel (BIM-SLG) augmented the dermal deposition of BIM, compared to naïve BIM gel. Furthermore, in vivo studies verified the efficacy of spanlastic vesicles to boost the cutaneous accumulation of BIM compared to naive BIM gel; the AUC0-12h of BIM-SLG was 888.05 ± 72.31 μg/mL.h, which was twice as high as that of naïve BIM gel (AUC0-12h 382.86 ± 41.12 μg/mL.h). Intriguingly, BIM-SLG outperforms both naïve BIM gel and commercial minoxidil formulations in stimulating hair regrowth in an androgenetic alopecia mouse model. Collectively, spanlastic vesicles might be a potential platform for promoting the dermal delivery of BIM in managing alopecia.

Abstract
To investigate the effect of retinoids, such as retinol (ROL), retinal (RAL), and retinyl palmitate (RP), on epidermal integrity, skin deposition, and bioconversion to retinoic acid (RA). 3-D human skin equivalent model (EpiDermFT™) was used. Epidermal cellular integrity measured by TEER values was significantly higher for a topical treatment of ROL and RAL than RP (p < 0.05). The skin deposition (μM) of ROL and RAL was approximately 269.54 ± 73.94 and 211.35 ± 20.96, respectively, greater than that of RP (63.70 ± 37.97) over 2 h incubation. Spectral changes were revealed that the CO maximum absorbance occurred between 1600∼1800 cm-1 and was greater from ROL than that from RAL and RP, indicating conjugation of R-OH to R-CHO or R-COOH could strongly occur after ROL treatment. Subsequently, a metabolite from the bioconversion of ROL and RAL was identified as RA, which has a product ion of m/z 283.06, by using liquid a chromatography-mass spectrometry (LC-MS) - total ion chromatogram (TIC). The amount of bioconversion from ROL and RAL to RA in artificial skin was 0.68 ± 0.13 and 0.70 ± 0.10 μM at 2 h and 0.60 ± 0.04 and 0.57 ± 0.06 μM at 24 h, respectively. RA was not detected in the skin and the receiver compartment after RP treatment. ROL could be a useful dermatological ingredient to maintain epidermal integrity more effectively, more stably deposit on the skin, and more steadily metabolize to RA than other retinoids such as RAL and RP.

Abstract
The purposes of current study were to investigate the effect of ginsenosides from BIOGF1K enriched in compound K (CK) and compound Y (CY) on the skin barrier function, the deposition in in vitro 3-D human tissue model (EpiDermFT™ Full Thickness 400), and to identify and quantify kinetic bioconversion of the ginsenosides in artificial skin by utilizing the Fourier transform infrared spectroscopy (FT-IR) and liquid chromatography mass spectrometry (LC-MS), respectively. Epidermal barrier integrity evaluated using transepithelial electrical resistance (TEER) was significantly higher in the BIOGF1K treatment than the CY or CK individual treatment throughout incubation (p < 0.05). Skin deposition (%) of CY and CK from BIOGF1K treatment was approximately 4 and 2 times higher than the CY and CK single component treatment, respectively. Total amount of CK found in human skin by deposition and bioconversion was approximately 1087.3, 528.82, and 867.76 μM after topical treatment of BIOGF1K, CK, and CY. Results from the current study reveal that topical treatment of BIOGF1K more effectively induced CK deposition as well as bioconversion of CY to CK than that of a single treatment of CY or CK, suggesting that BIOGF1K could be a useful cosmetic preparation for enhancing skin function.

Abstract
l-Glutathione (GSH) has exceptional antioxidant activities against UVA irradiation-induced oxidative stress and is used widely for combatting skin ageing. However, topical administration of GSH is challenging due to its inability to penetrate the stratum corneum (SC). This study aims to evaluate the solid lipid nanoparticles (SLNs) carrier system for improving the skin penetration and stability of GSH. The GSH-loaded SLNs (GSH-SLNs) were prepared by the double emulsion technique and were optimized by a full factorial design. The optimized GSH-SLNs formulation had a mean particle size of 305 ± 0.6 nm and a zeta potential of + 20.1 ± 9.5 mV, suitable for topical delivery. The ex-vivo penetration study using human skin demonstrated a 3.7-fold improvement of GSH penetration across SC with GSH-SLNs when compared with aqueous GSH. GSH-SLNs prolonged antioxidant activity on UVA irradiated fibroblast cells when compared to GSH solution, preventing UVA-induced cell death and promoting cell growth for times over 48 h. This research has illustrated that as a carrier system, SLNs were able to enhance the physicochemical stability, skin penetration, and drug deposition in the viable epidermis and dermis layers of the skin for GSH, while also maintaining the ability to protect human skin fibroblast cells against oxidative stress caused by UVA irradiation. This delivery system shows future promise as a topical delivery platform for the topical delivery of GSH and other chemically similar bioactive compounds for improving skin health.

Abstract
Some chemicals have been reported to cause metabolite-related phototoxicity, and this study aimed to verify the applicability of photosafety assessment based on photochemical and pharmacokinetic properties to evaluate the metabolite-related phototoxicity risk. The phototoxic risk of imipramine (IMI) and its metabolite, desipramine (DMI), was evaluated by photochemical and pharmacokinetic analyses. IMI and DMI were found to have similar photoreactivities based on the generation of reactive oxygen species. The skin concentrations of IMI and DMI reached maximal levels at approximately 1 and 4 h, respectively, after oral administration of IMI (10 mg/kg), and DMI showed high skin deposition compared with IMI. According to the results, DMI was identified as a contributor to phototoxicity induced by orally-taken IMI. In in vivo phototoxicity testing, ultraviolet A irradiation from 3 to 6 h after oral administration of IMI (100 mg/kg) caused more potent phototoxic reactions compared with that from 0 to 3 h, and DMI yielded by metabolism of IMI would be associated with phototoxic reactions caused by orally-administered IMI. In addition to the data on IMI, a parent chemical, photochemical and pharmacokinetic profiling of its metabolite, DMI, led to reliable phototoxicity prediction of orally-administered IMI. Thus, characterization of the photosafety of metabolites would generate reliable information on the phototoxicity risk of parent chemicals, and the proposed strategy may facilitate comprehensive photosafety assessment of drug candidates in pharmaceutical development.

Abstract
The dermal uptake and percutaneous penetration of ten organic flame retardants was measured using an ex vivo human skin model. The studied compounds were DBDPE, BTBPE, TBP-DBPE, EH-TBB, BEH-TEBP, α, β and γ-HBCDD as well as syn- and anti-DDC-CO. Little or none of the applied flame retardants was recovered in either type of the receptor fluids used (physiological and worst-case). However, significant fractions were recovered in the skin depot, particularly in the upper skin layers. The primary effect of the worst-case receptor fluid was deeper penetration into the skin. The recovered mass was used to calculate lower- and upper-bound permeability coefficients kp. Despite large structural variation between the studied compounds, a clear, significant decreasing trend of kp was observed with increasing log Kow. The results indicate that the dermis may provide a significant barrier for these highly lipophilic compounds. However, based on our results, dermal uptake should be considered in exposure assessments, though it may proceed in a time-lagged manner compared to less hydrophobic compounds.

Abstract
The potential of hydrogel containing nanostructured lipid carriers (NLC) to enhance the skin permeation rate and skin deposition of dexamethasone acetate (DEA) was investigated. The particle size of obtained NLCs was around 224.4 nm. NLCs had core-shell structure and DEA existed in amorphous state in NLCs. The permeation rate of DEA through excised mouse skins from hydrogel containing DEA-NLC (DEA-NLC-hydrogel) was 7.3 times higher than DEA-ointment. The skin deposition of DEA from DEA-NLC-hydrogel increased 3.8 folds compared to that from solution of DEA in hydrogel (DEA-hydrogel).

Abstract
The purpose of this study was to examine the effect of stabilization of retinyl palmitate (RP) on its skin permeation and distribution profiles. Skin permeation and distribution study were performed using Franz diffusion cells along with rat dorsal skin, and the effect of drug concentration and the addition of pectin on skin deposition profiles of RP was observed. The skin distribution of RP increased in a concentration dependent manner and the formulations containing 0.5 and 1 mg of pectin demonstrated significantly increased RP distributions in the epidermis. Furthermore, it was found that skin distribution of RP could be further improved by combined use of pectin and ascorbyl palmitate (AP), due largely to their anti-oxidative effect. These results clearly demonstrate that the skin deposition properties of RP can be improved by stabilizing RP with pectin. Therefore, it is strongly suggested that pectin could be used in the pharmaceutical and cosmetic formulations as an efficient stabilizing agent and as skin penetration modulator.
