Background: Striae distensae are common disfiguring atrophic dermal scars. Fractional lasers have been utilized to improve the appearance of this condition.

Objectives: To compare the efficacy and safety of picosecond fractional 1064-nm Nd:YAG (PS Nd:YAG) laser versus fractional 10,600-nm Carbon Dioxide (CO2) laser in treating abdominal striae alba (SA).

Methods: Thirty-two women with Fitzpatrick skin types III-V and abdominal SA participated in a split-abdomen study, receiving four sessions of fractional PS Nd:YAG and CO2 laser treatments on each side at four-week intervals. Striae texture, atrophy, clinical improvement, and satisfaction were assessed for each side at one and three months, with striae length and width compared pre- and post-treatment. Adverse reactions were noted at each visit.

Results: Abdomen treated with both lasers had significantly improved skin texture, atrophy and clinical improvements (assessed by physicians and patients) at both follow-ups (p < 0.05), with no difference between the two. Striae length and width did not change significantly (p = 0.203 and p = 0.558). Patients reported greater improvement on the CO2-treated side at 1 month, but not at the final follow-up. High satisfaction was noted for both lasers. Adverse reactions noted after both lasers include erythema, edema, crusting/scaling, pruritus, pain and post-inflammatory hyperpigmentation. The PS Nd:YAG laser was associated with greater pain (p < 0.05), but shorter healing time of 10.26 days.

Conclusion: Both fractional PS Nd:YAG and CO2 lasers were effective, well-tolerated and safe treatment options for SA.

Periorbital skin photoaging is a common cosmetic problem.Presently, conventional treatment methods cannot achieve satisfactory results. Periorbital skin aging may benefit from platelet-rich plasma (PRP) injection. However, there is little experimental evidence on the safety and efficacy of PRP in the treatment of periorbital skin photoaging. To examine the safety and efficacy of PRP injection in the treatment of periorbital skin photoaging, PRP was injected into the periorbital skin of 20 patients, and patient satisfaction was assessed at the first month (M1), the second month (M2), and the third month (M3) after treatment. Two experienced dermatologists independently evaluated the patient's skin before and after treatment according to internationally accepted guidelines. The objective indicators of skin hydration, melanin index, erythema index, skin brightness, transepidermal water loss (TEWL), skin elasticity, and skin thickness were measured. Some subjective indicators, including pigmentation around the eyes, suborbital wrinkles, and static crow's feet, were significantly improved. Some objective indicators, including skin brightness, skin thickness, and collagen strength, were also significantly improved. Eye bags and TEWL slightly improved, but the differences were not statistically significant. The overall patient satisfaction with the treatment was high, no serious complications were noted, and the recovery profile was favorable. PRP injection was safe and effective for the treatment of periorbital skin photoaging.

Post-inflammatory hyperpigmentation represents an acquired pigmentation anomaly frequently observed as a common sequela following acute or chronic skin inflammation, which often poses a challenge for treatment. We report a patient who developed persistent, mottled pigmentary macules all over her face subsequent to mesotherapy treatment. The patient was treated with a picosecond 1064 nm Nd:YAG laser in a two-step procedure way combined with a large- spot size, low-fluence mode and a fractional mode. After two treatment sessions, considerable improvement in her pigmentary lesions was observed, with no exacerbation or other complications.

In the absence of visual perception of the subcutaneous blood vessels, the performance of facial filling procedures may result in serious complications, such as blindness, cerebral infarction, and potentially fatal outcomes. In order to improve the visibility of facial vessels to ensure the filler injection procedure safe, this paper reports an efficient physical-based image fusion approach that combines simultaneously captured visible and near-infrared (NIR) images to produce vessel-highlighted effects. The enhancement of vessels visibility involves applying a customized sharpening filter to the invisible NIR image prior to merging it with the color facial image. The quantitative and subjective assessments of the fusion images indicate that the suggested approach is capable of efficiently reproducing a clear representation of blood vessels and realistically preserving their color and structural texture. Therefore, this new approach may be utilized to improve the efficiency and accuracy in locating or marking facial blood vessels and enhance the injection safety and precision of surgical filler injections.

Background: The use of non-ablative fractionated lasers for skin rejuvenation has been proven to be effective in improving skin texture, and has become popular due to minimal wounding, significantly shorter recovery times and decreased adverse effects.

Objective: To retrospectively analyze improvement in skin texture in healthy women aged over 18 years with Fitzpatrick skin type II-IV.

Methods: Participants received 3 facial and/or neck treatments with the 1570-nm fractional scanning diode laser at one-month intervals. Three months after the last treatment session two blinded evaluators assessed skin improvement using before and after photos. Pain and patient satisfaction were recorded.

Results: Sixteen women with a mean age of 45.4 ± 4.1 years (range 35-50 years) and skin type II-IV were included in the analysis. All 16 participants received facial treatments and seven (43.8%) also received neck treatments. Three months follow-up evaluation showed that the majority of participants had at least a visible change in the treated areas. Mean pain score was low and decreased with each treatment session.

Conclusion: Skin treatment using fractional scanning 1570-nm diode laser improves skin laxity in women with skin types II-IV. Larger studies are warranted to further clarify the efficacy and safety of this modality.

Background: Autologous fat transplantation has gained increasing attention in the field of cosmetic surgery. However, a series of complications can occur after fat transplantation.

Case presentation: A 24-year-old woman presented at our Hospital with nasal skin necrosis and ulceration. She had undergone autologous fat transplantation on the nose six days ago. Physical examination showed an abnormal skin range of approximately 5 × 2 cm on the left side of the nose. The initial diagnosis was "skin necrosis after autologous fat grafting for augmentation rhinoplasty." In addition to the conventional treatment, topical oxygen therapy (TOT) and platelet-rich fibrin (PRF) injection were applied to the nasal wounds area. After 16 days, the pale and dark areas of necrosis on nose were scabby, and the local skin conditions were significantly improved.

Conclusion: We treated a case of ischemic necrosis of the skin after autologous fat grafting for augmentation rhinoplasty. For this kind of local vascular embolism, we first proposed a comprehensive therapy of "biological + physical + drug." The therapeutic method achieved satisfactory results, providing a new strategy for the clinical treatment of vascular embolism.

Granuloma faciale is a benign and rare skin disease, which usually presents as well-defined red-purple asymptomatic plaques or nodules on the face but can also present extra-facially. It poses a significant therapeutic challenge, with varying degrees of success reported by a range of medical and surgical treatments. We describe a 41-year-old lady with biopsy-confirmed facial granuloma faciale, affecting her nose, cheeks, upper lip, and forehead, who had failed a variety of medical treatments, UVB phototherapy, and pulsed dye laser. She was successfully treated with ablative fractional CO₂ laser, with a sustained response, without recurrence or complications maintained for 1 year.

The high-frequency generator is considered a collagen stimulator and skin revitalizer, however there are few studies exploring its effects in the field of rejuvenation and aesthetics. Thus, this study aimed to investigate the impact of high frequency generator therapy on facial aging. A total of 26 participants aged between 50 and 60 years were selected and received high frequency generator treatment for eight weeks. The evaluation was conducted using a combination of photographic records and assessment tools, including Rosenberg scale, perception and satisfaction with treatment evaluation, overall aesthetic improvement scale, and modified Fitzpatrick scale. The analysis conducted by the Global Aesthetic Improvement Scale yielded significant results. The Modified Fitzpatrick Wrinkle Scale showed that high frequency therapy led to statistically significant improvements in the appearance of nasolabial wrinkles (right T0: 1.48, T8: 0.87; left T0: 1.51, T8: 1.05) and periorbital wrinkles (right T0: 1.69, T8: 1.05; left T0: 1.71, T8: 1.08). In conclusion, high frequency generator therapy can be a highly effective tool for treating skin aging on the face, however, we recommend that future research includes control groups, and adopts objective measures to expand knowledge about the effects of high frequency.
