Efficacy, safety, and guidelines of application of the fractional ablative laser erbium YAG 2940 nm and non-ablative laser erbium glass in rejuvenation, skin spots, and acne in different skin phototypes: a systematic review

Extensive facial scarring after ablative laser resurfacing in a patient with frontal fibrosing alopecia

“…Ablative laser therapy achieves its effect through the ablation of the full-thickness dermis and the subsequent re-epithelialization. 3 Ablative lasers in skin rejuvenation therapy are well established treatment modalities. 3 , 4 Postprocedural erythema and edema are the most common complications from ablative laser therapy, followed by pain and peeling.…”

“… 3 Ablative lasers in skin rejuvenation therapy are well established treatment modalities. 3 , 4 Postprocedural erythema and edema are the most common complications from ablative laser therapy, followed by pain and peeling. 3 Hypertrophic scarring can occur as a rare complication, with limited cases reported in the literature.…”

“… 2 The fractional erbium laser is among the most frequently used resources in dermatology for facial rejuvenation. 3 Laser resurfacing is regarded as a useful modality of treatment for acen scarring with a low risk for serious complications. 3 , 4 We hereby present a case of extensive scarring after ablative laser resurfacing in a patient with undiagnosed FFA.…”

“… 3 Laser resurfacing is regarded as a useful modality of treatment for acen scarring with a low risk for serious complications. 3 , 4 We hereby present a case of extensive scarring after ablative laser resurfacing in a patient with undiagnosed FFA. This article aims to illustrate the likely mechanism of extensive scarring after ablative laser resurfacing in patients with FFA and thereby convey the importance of recognizing this condition in the daily practice of laser dermatology.…”

The efficacy of fractional erbium:YAG laser (2940 nm) compared to Microneedling of topical amniotic membrane stem cell conditioned medium (AMSC-CM) for photoaging

“…7 The clinical use of lasers in treating dermatological disorders such as skin spots, atrophic acne scars, chronological aging, and cutaneous aging has been growing in recent years. 8 This type of erbium laser can be found at wavelengths of 1540 or 1550 nm, which are classified as non-ablative erbium glass, and at 2940 nm, classified as ablative erbium YAG. Ablative fractional lasers destroy the superficial layers of the skin, to improve the appearance of the skin after epithelialization.…”
