Excimer laser therapy can be an alternative for treating superficial morphea when topical steroids don't work.

This study reported that long-pulse alexandrite laser treatment achieved an overall hair reduction rate of 80.8% among patients, with minimal cases of hypo- or hyperpigmentation.

In this multi-center study, the incidence of acneform reactions after laser hair removal was found to be 6%, with younger age, Nd:YAG laser use, and Fitzpatrick skin type V increasing susceptibility.

This review discusses the potential enhanced effectiveness of combining Eflornithine cream with laser or light-based systems for facial hair removal and emphasizes the need for safer and more satisfactory solutions.

Among individuals with skin types II and III, this study found the 755 nm laser more effective for axillary hair removal than the dual-wavelength laser, with a better safety profile and enduring results up to 12 months.

This article discusses various approaches to potentially prevent hair loss, including stress management, increasing fresh air exposure, avoiding hair dyes, and considering laser hair restoration, suggesting that identifying and addressing the cause of hair loss may help mitigate it.

This study observed increased proliferation and certain gene expressions in dermal papilla cells exposed to an 808 nm laser diode array at doses above 0.5 J/cm².

In this study, researchers observed that while paradoxical hypertrichosis occurred after laser hair removal in some cases, using daily sun protection and diode laser SHR significantly reduced its incidence, with the periareolar area identified as a high-risk region.

This study discusses the importance of understanding the physical and biophysical factors involved in laser hair removal, highlighting the role of device parameters and skin type in treatment effectiveness, while also acknowledging potential adverse effects from laser light exposure.

This study found that the long-pulsed alexandrite laser effectively reduced hair growth with varying efficacy depending on the pulse duration, anatomic location, and number of treatments, without causing permanent adverse effects in skin types I–III.

This study found that normal mode ruby laser treatment for hirsutism is well tolerated and results in significant hair count reduction for at least six months, with multiple treatments offering greater effects.

In this clinical study, low-level laser therapy using the HANDI-DOME LASER device increased hair counts by 51% compared to controls, indicating its potential as a safe and effective treatment for androgenetic alopecia in women aged 18 to 60.

This study found that three treatments with the 810-nm diode laser improved skin texture and roughness/bumpiness in keratosis pilaris patients, although it did not reduce redness.

This study found that cold air can effectively preserve the epidermis when using an 810 nm diode laser, but it is slightly less effective than a chilled sapphire window in dark-haired pigmented pigs.

This review suggests that paradoxical hair growth after light-based treatments is unlikely due to the devices themselves; instead, it may be linked to other factors such as inflammation in individuals with certain conditions.

This review discusses the mechanisms of laser and IPL hair removal, particularly for darker skin types, and reports no new findings, highlighting potential adverse effects like pigmentation changes or scarring with improper use.

This randomized trial found that diode laser achieved more favorable long-term hair removal outcomes but induced more discomfort and transient adverse effects compared to intense pulsed light in women with Fitzpatrick skin types I-IV.

In this study, treatment of unwanted hair with 755 nm alexandrite laser in 14 patients showed a decrease in excess hair at the armpit and thigh areas, with a 75% accuracy rate in hair density estimation using Monte Carlo modeling.

This study found that low-level laser/light therapy is effective and safe for treating mild to moderate androgenetic alopecia in individuals with certain skin types, especially when combined with other treatments, although further research is needed to refine protocols and verify long-term outcomes.

Lasers are effective for some skin conditions but can cause side effects like scarring and pigment changes; careful selection is important, and botulinum toxin type A is successful in reducing sweat in palmar hyperhidrosis.

This study found that Nd:YAG laser-assisted hair removal achieved high satisfaction with minimal complications among individuals with dark-complexioned skin seeking unwanted hair reduction.

This study presents a case of a pubertal girl with type 1 diabetes who developed proliferative diabetic retinopathy shortly after diagnosis, suggesting the need for earlier screening in high-risk groups.

This study observed that the glassy layer of hair follicles in guinea pigs consists of thick collagen-type fibrils organized into two distinct arrays, whereas in young mice, the fibrils are thinner and develop between the outer root sheath and fibroblasts.

In this study, researchers conducted additional IHC staining on equine skin sections and found that collagen type III primarily labels the extracellular matrix, while anti-PDGFR-antibody staining highlights cells with long-shaped processes mainly arranged around hair follicles.

This study found that the long-pulse Nd:YAG laser effectively reduces unwanted facial hair across various skin types, with hair regrowth delayed significantly longer than with self-applied methods.

This study reports the cloning and expression details of two new human type II keratins, K6irs3 and K6irs4, in the hair follicle's inner root sheath, suggesting a distinct functional role related to hair structure.

This study found that treatment with fractional 1064 nm picosecond Nd:YAG laser effectively reduced post-acne erythema in adult Chinese patients without causing scarring or pigmentation issues, though some experienced temporary erythema, oedema, pruritus, and acne eruptions.

Tailored nonsurgical cosmetic procedures are crucial for safely treating diverse skin types, especially skin of color.

This overview highlights the effectiveness of fractional lasers, particularly fractional erbium:YAG, in treating various skin conditions with customizable settings and a short recovery time, while noting potential risks and the importance of tailored applications for different skin types.

In this case study, Botulinum toxin type A injections were associated with improved hair growth and scalp condition in a patient with radiation-induced alopecia, though the mechanisms remain speculative.
