However, various underlying factors may impede this process. Here, we present a complex patient with severe perioral hyperpigmentation due to FDE, who showed marked improvement after six sessions of intradermal tranexamic acid (TXA) injections.</p><p>A 50-year-old female patient presented with a 1-year persistent hyperpigmentation on her lips and perioral area after repeatedly taking Ibuprofen to manage fever during the COVID-19 pandemic. The pigmentation worsened with continued use of the medication (Figure 1A). Despite discontinuing ibuprofen and using topical hydroquinone and tretinoin for over 6 months, her hyperpigmentation became even more severe. A diagnosis of PIH caused by FDE was made. After discussing with her, we advised strict sun protection and avoidance of physical irritation of the lips. Additionally, we introduced intradermal injections of TXA due to its anti-inflammatory and anti-melanin-producing properties. The TXA solution was prepared by diluting 0.2 mL of a 500 mg/5 mL ampoule in sterile water to a 10 mg/mL concentration, yielding a total of 2 mL. The injections were administered intradermally at a 15°–20° angle, targeting the superficial dermis and creating small semicircular wheals. During each session, 0.1 mL doses were injected 5 mm apart across 14 sites, totaling 1.4 mL per session. After six monthly TXA sessions, the patient's perioral hyperpigmentation showed significant improvement (Figure 1B).</p><p>The type IV hypersensitivity reaction caused by FDE leads to damage to keratinocytes and melanocytes. Following drug withdrawal, dermal macrophages then phagocytize extravasated melanin, causing persistent PIH [<span>1</span>]. Basically, PIH from FDE is self-limiting [<span>1</span>]. However, in this case, the patient's hyperpigmentation not only failed to resolve but also worsened progressively after treatment. Hence, we considered there were additional factors that contributed to her atypical progression. First, her lesion is located on the lip, an area exposed to UV radiation and friction from eating. Second, she was in her perimenopausal period, also with skin type IV—a combination of skin type and fluctuating hormones that likely exacerbated her hyperpigmentation. Third, we can find that she also had melasma (Figure 1A), indicating a preexisting pigment metabolism abnormality. Collectively, factors such as UV exposure, mechanical friction, skin type, hormonal changes, and pigment metabolism issues likely intensified the pigmentation [<span>2</span>]. Therefore, for this patient, discontinuing the offending drug alone was insufficient; effective anti-inflammatory and antipigment treatments were necessary to counteract these ongoing factors contributing to persistent hyperpigmentation.</p><p>Topical treatments, such as retinoids, hydroxy acids, and broad-spectrum photoprotection, are th","PeriodicalId":15546,"journal":{"name":"Journal of Cosmetic Dermatology","volume":"24 2","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jocd.70061","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143389213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These advanced AI systems are designed to process and generate human-like text by analyzing vast amounts of data. Through natural language processing (NLP), LLMs offer innovative solutions that improve patient care, facilitate clinical workflows, and accelerate research efforts. However, while these models hold significant potential, it is crucial to address their limitations, as well as the ethical considerations and regulatory challenges associated with their use, to ensure responsible implementation [<span>1, 2</span>].</p><p>At their core, LLMs are sophisticated computer programs capable of understanding and generating human-like text. Imagine conversing with a knowledgeable assistant who can quickly summarize medical research, suggest treatment options, or answer complex questions. LLMs achieve this by learning patterns from extensive datasets, including books, articles, and scientific journals. With this training, they can synthesize information and provide coherent responses to user inquiries [<span>3</span>].</p><p>LLMs are expanding several aspects of cosmetic dermatology. One key application lies in patient education. By simplifying complex medical terminology, LLMs make cosmetic procedures, such as dermal fillers, neurotoxins, and laser therapies, more accessible to patients. This improved communication enables patients to make informed decisions about their care. Additionally, these tools have the potential to bridge knowledge gaps in underserved communities, although challenges like limited digital proficiency and internet access still persist.</p><p>Another critical application is personalized treatment planning. LLMs can analyze patient histories, procedural risks, and desired outcomes to provide evidence-based recommendations. For instance, they may suggest combining microneedling with platelet-rich plasma therapy to achieve optimal skin rejuvenation. While this personalization can enhance treatment outcomes, it requires clinician oversight to ensure that recommendations match individual patient needs and are free from bias.</p><p>LLMs also contribute to administrative efficiency in dermatology practices. Integrating these tools into electronic medical record (EMR) systems can automate tasks such as clinical note-taking, scheduling, and insurance coding. This automation reduces administrative burdens, allowing clinicians to devote more time to direct patient care [<span>4</span>].</p><p>Follow-up care and monitoring are additional areas where LLMs show efficiency.

While Nishikawa et al. [<span>2</span>] focused on adverse events such as paradoxical bulging, sunken cheeks, and facial asymmetry, we would like to propose parotitis as an additional adverse effect based on recent literature.</p><p>Research on the impact of BTX injections into masticatory muscles in the parotid gland is limited. While some reports observed no severe adverse effects or mild xerostomia accompanied by normal salivary flow rates [<span>3</span>], other studies report patients having reduced salivary volume and thicker saliva [<span>4</span>].</p><p>The proximity of the masseter muscle to the parotid gland suggests that any neuromodulator injection to this area could inadvertently affect the parotid gland. Several mechanisms have been proposed for this effect. Anatomically, the proximity of the injection site to critical structures could lead to inadvertent influence on salivary output [<span>4</span>]. Additionally, the complex and variable branching of the facial nerve, including the potential secretomotor branch, could be affected and thereby altering salvation [<span>5</span>]. Physical factors such as gravitational flow, injection pressure, or diffusion of the neuromodulator across fascial planes could further promote unintended BTX spread [<span>5-7</span>]. Reduced muscular support around the gland may also alter intraglandular pressure and decrease salivary flow [<span>7</span>]. Physiological factors, for instance, efficient local uptake or systemic neurotoxin spread may impair salivary production as well [<span>8</span>]. All of which may lead to hyposalivation, causing stasis in the gland and potential retrograde infection [<span>9</span>].</p><p>Parotitis induced by BTX injection, although rare, should be carefully considered by clinicians performing these procedures. Given the increasing use of BTX in both therapeutic and aesthetic practices, even rare complications may occur. When administering BTX, it is vital to pay attention to the accuracy of the injection site. Palpation should be used to delineate the bulk of the masseter muscle, targeting its hypertrophic region while avoiding the posterior border of the muscle [<span>4</span>]. The needle should be inserted perpendicularly. The appropriate injection depth has a crucial role as well. The needle should be inserted deep and encounter the ramus, minimizing the risk of invading the parotid gland [<span>10</span>]. In order to avoid unwanted results, two fundamental pillars need to be preserved. First, proper case selection is mandatory.

TG took two tablets of multi-plant concentrated powder daily, while PG took placebo tablets without active ingredients. The study lasted 12 weeks. Plasma Trolox equivalent antioxidant capacity (TEAC), superoxide dismutase (SOD), and glutathione peroxidase (GPx) were measured at week 0 (W0), week 8 (W8), and week 12 (W12). Skin brightness (<i>L</i>* value), skin tone (Individual Typological Angle (ITA°)), erythema (<i>a</i>* value), skin spots, and wrinkles were assessed at week 0 (W0), week 4 (W4), week 8 (W8), and week 12 (W12).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>The study showed significant improvements in all three antioxidant markers in the blood after consuming the compound ingredient tablets compared to the PG (<i>p</i> < 0.01). <i>L</i>* value and ITA° significantly increased from 8 weeks (<i>p</i> < 0.1).

Dark skin and incorrect laser parameters are common causes, but PIH is often unexpected for patients. Obvious hyperpigmentation can lead to an ugly appearance and severe anxiety. Therefore, a fast and effective treatment for laser-induced PIH is necessary. In this article, we attempted to demonstrate that a low-fluence Q-switch (QS) 1064 nm laser combined with oral tranexamic acid (TXA) is a quick and safe method for the clearance of laser-induced PIH.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Materials and Methods</h3>\u0000 \u0000 <p>A retrospective cohort study, adhering to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines, spanning 2 years (2021–2023) was conducted on 23 patients aged between 29 and 58 years. These patients were diagnosed with laser-induced PIH for < 3 months. The treatment regimen was a low-fluence QS1064 nm laser combined with oral TXA, oral TXA was first taken, and a low-fluence QS1064 nm laser was used for at least 1 month after the last laser was applied. Three to six laser treatments were subsequently applied. After treatment, the pigment color and patient satisfaction were assessed to evaluate the effectiveness of the treatment options.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Twenty patients were enrolled in the study, the average laser treatments were 4.3 ± 0.865 times. The Melasma Area and Severity Index (MASI) score decreased from 9.325 ± 3.38 before treatment to 5.97 ± 2.37. After the first treatment, the MASI score decreased by approximately 40%. Two months after the last treatment, the MASI score decreased to 0.93 ± 1.06, and there was a statistically significant difference in the MASI score before and after treatment (<i>p</i> < 0.05). Patient satisfaction scores revealed that 95% of patients were highly or strongly satisfied with the decrease in the intensity of the PIH color, with a moderate response rate of 1 (5%). The patients thought that the pigment removal speed was 75% (15) very fast or fast, 20% (4) moderate, and 5% (1) slow.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>The results of this study demonstrated the quick and safe removal of laser-induced PIH following treatment with low-fluence QS1064 nm laser combined with oral TXA.
