Abstract
BACKGROUND Energy-based devices, such as nonablative lasers, are a promising method to enhance the delivery and absorption of topically applied molecules. OBJECTIVE To characterize ex vivo uptake of common antioxidant topicals after pretreatment with a nonablative laser wavelength. MATERIALS AND METHODS Using donor human skin tissue, uptake of 3 topical antioxidants was analyzed (C E Ferulic with 15% l-ascorbic acid [15% vitamin C serum], Phloretin CF with ferulic acid [10% vitamin C serum], and Phyto+ [botanical serum]; SkinCeuticals, Dallas, TX; 2010 formulations) after pretreatment with a 1,440-nm nonablative fractional diode laser. RESULTS Pretreatment with the 1,440-nm laser enhanced uptake of 15% and 10% vitamin C serums by approximately 10 and 21 times, respectively, compared to controls. Laser pretreatment also enhanced uptake of botanical serum by approximately 6 times relative to controls. Permeation of vitamin C and botanical serums was also enhanced through laser pretreatment. CONCLUSION Nonablative laser pretreatment increased uptake and permeation of topical antioxidants. Optimizing treatment requires consideration of the device and treatment parameters as well as the properties of the topical formulation.

The Use of Lasers and Light Devices in Acne Management: An Update. Am J Clin Dermatol 2021; 22:785-800.

Abstract
Acne vulgaris is a disease of the pilosebaceous unit and the most common inflammatory dermatosis worldwide. It is also associated with significant economic burden. Limitations of conventional topical and systemic treatments include long treatment course, intolerable adverse effects, antibiotic resistance, and patient compliance. Therefore, laser and light-based interventions present as alternative options over the past decade and have been used in combination with conventional pharmacological therapies and other physical modalities. An updated overview on the use of lasers and light-based devices in acne management is presented to help clinicians understand the safety and efficacy of these treatment options. The effectiveness of neodymium:yttrium aluminum garnet (Nd:YAG) for treating acne is supported by more high-level studies compared with other laser devices. There is limited evidence to support the use of CO2 lasers, potassium titanyl phosphate lasers, and 1565-nm non-ablative fractional lasers for treating acne. Among light devices, photodynamic therapy is the most studied, showing higher efficacies than some of the conventional topical and oral acne therapies. Intense-pulsed light and blue light therapies also show favorable outcomes. A limitation is that most studies are non-randomized and lack a control group, and report on a variety of device settings, treatment regimens, and outcome measures, making it challenging to summarize and generalize findings. Although the use of laser and light devices to treat acne is promising, further work with randomized controlled study designs and larger sample sizes will provide improved guidance on the application of these modalities.

Abstract
Background and Objectives Treatment of photoaging and intrinsic aging of the chest, with the associated concerns of skin roughness, uneven pigmentation, laxity, atrophy, and telangiectasias, can be problematic because of the potential for worsened esthetic outcomes with existing treatments. This study assessed the efficacy and safety of using nonablative fractional laser therapy (FLT) pretreatment with photodynamic therapy (PDT) versus PDT alone for chest rejuvenation. Study Design/Materials and Methods In a randomized, evaluator‐blinded, split‐sided study, adult female patients with photodamage to the chest received three treatment courses over an 8‐week period with follow‐up visits at Weeks 12 and 20. FLT was applied to one side of the chest, randomly assigned at baseline, followed by aminolevulinic acid‐based PDT, delivered using a thermal, short incubation, broad area technique, to both sides of the chest. In‐person and photographic assessments were conducted using five‐point scales to evaluate outcomes including rhytides, pigmentation, skin texture, and telangiectasias. Results Eleven adults completed the study, of whom 11 had improved scores for rhytides and 10 had improved scores for skin texture at Week 20. There was no significant difference in any efficacy outcome between FLT and PDT and standard PDT alone. The severity of adverse events was rated significantly greater with the combined FLT–PDT treatment vs PDT alone. Conclusions Significant improvements were observed vs baseline for both sides of the chest treated with FLT–PDT or standard PDT following three treatment sessions. No significant difference in efficacy was observed between treatment approaches, although adverse events were more severe on the FLT‐pretreated side. This study was not registered as it qualified as a nonsignificant risk study. Lasers Surg. Med. © 2019 The Authors. Lasers in Surgery and Medicine Published by Wiley Periodicals, Inc.

Abstract
5-Aminolevulinic acid (ALA) is an important cellular metabolic intermediate that has broad agricultural and medical applications. Previously, attempts have been made to synthesize ALA by multiple enzymes in cell free systems. Here we report the development of a semi-permeable system for ALA production using stable enzymes. Glucose, sodium polyphosphate, ATP, tRNA, glutamate and NADPH were used as substrates for ALA synthesis by a total of nine enzymes: adenylate kinase, polyphosphate kinase, glucose-6-phosphate dehydrogenase, phosphogluconolactonase, 6-phosphogluconate dehydrogenase, glutamyl-tRNA synthetase and glutamate-1-semialdehyde aminotransferase from E. coli, hexokinase from yeast, as well as glutamyl-tRNA reductase and its stimulator protein glutamyl-tRNA reductase binding protein (GBP) from Arabidopsis in a semi-permeable system. After reaction for 48 h, the glutamate conversion reached about 95%. This semi-permeable system facilitated the reuse of enzymes, and was helpful for the separation and purification of the product. The ALA production could be further improved by process optimization and enzyme engineering.Abbreviations: PPK: polyphosphate kinase; ADK: adenylate kinase; ALA: 5-Aminolevulinic acid; HK: hexokinase; ZWF: glucose-6-phosphatedehydrogenase; PGL: phosphogluconolactonase; GND: 6-phosphogluconate dehydrogenase; GTS: glutamyl-tRNA synthetase; GTR: glutamyl-tRNA reductase; GBP: GTR binding protein; GSAAT: glutamate-1-semialdehyde aminotransferase.

Abstract
As we gain a greater understanding of acne pathogenesis, both new agents as well as new uses for established drugs are being considered for the treatment of acne vulgaris. Multiple clinical trials assessing new formulations or combinations of established acne treatments have been conducted, and novel uses of antimicrobials such as modified diallyl disulfide oxide and nitric oxide are being assessed in clinical trials. There are also a multitude of new therapies currently being studied that target the inflammatory cascade of acne pathogenesis, including sebosuppressive and anti-inflammatory phytochemicals, and small molecule inhibitors targeting sebaceous glands and enzymes, among others. Laser and light therapy is also being modified for the treatment of acne through combination methods with metal nanoshells and vacuum assistance. Probiotics have gained popularity in medicine as greater knowledge of the microbiome and its effects on multiple organ systems is being elucidated. Studies describing the positive effects of certain ammonia-oxidizing bacterial strains in the regulation of the skin's inflammatory response are ongoing. Therapies for acne are constantly evolving and current gold-standard acne therapy may be supplemented with novel treatment modalities in the near future.

Abstract
Photodynamic therapy (PDT) employs a photosensitizer (PS) and visible light in the presence of oxygen, leading to production of cytotoxic reactive oxygen species, which can damage the cellular organelles and cause cell death. In dermatology, PDT has usually taken the form of topical application of a precursor in the heme biosynthesis pathway, called 5-aminolevulinic acid (or its methyl ester), so that an active PS, protoporphyrin IX accumulates in the skin. As PDT enhances dermal remodeling and resolves chronic inflamation, it has been used to treat cutaneous disorders include actinic keratoses, acne, viral warts, skin rejuvenation, psoriasis, localized scleroderma, some non-melanoma skin cancers and port-wine stains. Efforts are still needed to mitigate the side effects (principally pain) and improve the overall procedure.
