“…Practically, the 1450‐nm laser is not being used in the United States because of the amount of pain it caused to patients. However, recent studies have shown that using relatively lower energy with a double‐pass technique as applied in this study is as effective, less painful, and better tolerated, and subsequent studies also confirmed the findings . The level of pain of the double‐pass, low‐fluence DL treatment has been reported to be moderate (visual analogue scale 4.8–5.3/10), which is comparable to or lower than that of non‐ablative fractional laser widely used .…”

“…153 Several studies have found the 1450 nm diode laser can improve acne and it has been shown to cause sebaceous gland destruction in a rabbit ear model and in ex vivo human skin. [154][155][156][157][158][159] To improve efficacy and reduce side-effects of laser-based treatments, attempts have been made to concentrate the thermal injury to the sebaceous glands while sparing surrounding structures using gold-coated silica and silver microparticles. While a gold-coated silica microparticle suspension is currently marketed in Europe, it is not available in the United States and two recent trials of a topical silver photoparticle compound in conjunction with 810 nm and 1064 nm lasers did not achieve the primary efficacy endpoints.…”

Acne is one of the most common diseases worldwide and affects approximately 50 million individuals in the United States. Oral antibiotics are the most common systemic agent prescribed for the treatment of acne. However, their use may be associated with a variety of adverse outcomes including bacterial resistance and disruption of the microbiome. As a result, multiple treatment guidelines call for limiting the use of oral antibiotics in the treatment of acne, although actual prescribing often does not follow these guidelines. In this review, the rationale for concerns regarding the use of oral antibiotics for the management of acne is reviewed. In addition, we will discuss our approach to complying with the intent of the guidelines, with a focus on novel topical agents, dietary modification, laser and light-based modalities, and systemic medications such as spironolactone, combined oral contraceptives, and oral isotretinoin. Antibiotic resistance is a growing problem across medicine and rates of antibiotic resistance among isolates of Cutibacterium (formerly Propionibacterium) acnes have been rising, including to tetracycline-class antibiotics. 1-4 In addition to resistance among C. acnes, the use of oral antibiotics is associated with disruption of the normal flora, bacterial resistance among other organisms, and increased rates of upper respiratory infection and pharyngitis. 5-8 Antibiotic use may also be associated with inflammatory bowel disease and collagen vascular disease. 7-16 Finally, there may be an association between the use of oral tetracycline-class antibiotics and risk of breast and colon cancer. 17,18 As a result, there have

).Laser resurfacing technologies represent an exciting development in the cosmetic surgeon's repertoire to improve the tone, texture, and pigmentation of the skin. Although laser resurfacing is not a substitute for a facelift or blepharoplasty, the appropriate laser not only tightens the skin somewhat but also improves the appearance of lentigines, rhytides, skin texture, and a wide variety of scars.There are ablative and nonablative lasers as well as fractionated and nonfractionated lasers. Nonfractionated lasers act on the entire projected surface area of the treated skin, whereas fractionated lasers target an equally distributed portion of the projected area. An easy way to understand the difference is in looking at the pixels that compose a TV image. Nonfractionated devices treat every single pixel whereas fractionated devices treat only a percentage of the pixels in the treatment area.Ablative lasers vaporize tissue and therefore are more aggressive compared with the gentler nonablative lasers that leave the skin intact. Although ablative lasers result in far more down time and a more difficult recovery process, they remain the lasers that produce the most dramatic outcomes. For more severe facial wrinkles, dyspigmentation, and textural skin challenges, the ablative laser is often the treatment of choice.For patients seeking more moderate improvement-without the possible side effects of ablative lasers-nonablative lasers are often ideal. These lasers leave the epidermis intact while producing rejuvenating skin effects. Depending on the technology, nonablative laser treatments may minimize the appearances of finer wrinkles, ameliorate the texture and tone of the skin, and treat dyspigmentation. By comparison, the treatments are gentler and require little to no downtime, but produce a more moderate response.Ultimately, a patient's needs dictate the selection of the ideal laser. In this review, we seek to demystify the differences between the many available lasers and thereby facilitate the identification of the most appropriate laser for the patient. Ablative Nonfractionated LasersAblative skin resurfacing removes the epidermal layer, producing the most dramatic laser-treated results for skin resurfacing. The lasers quickly superheat water molecules in the skin tissue. When the water turns into gas, the skin cells are vaporized in a precise skin-peeling effect. This effect promotes collagen formation and retraction of the dermis and AbstractNumerous laser platforms exist that rejuvenate the skin by resurfacing its upper layers. In varying degrees, these lasers improve the appearance of lentigines and rhytides, eliminate photoaging, soften scarring due to acne and other causes, and treat dyspigmentation. Five major classes of dermatologic lasers are currently in common use: ablative and nonablative lasers in both fractionated and unfractionated forms as well as radiofrequency technologies. The gentler nonablative lasers allow for quicker healing, whereas harsher ablative lasers tend to be more effective. Fract...
