Zhengzhou Fuda Dermatological Hospital: Analysis of Standardized Diagnosis and Treatment Pathways for Disfiguring Birthmarks and Scars
Birthmarks and scars are common disfiguring skin conditions in clinical practice. Pigmented and vascular birthmarks, as well as hypertrophic scars, atrophic scars, keloids, and other skin lesions, not only affect appearance, but some also carry risks of continuous progression, ulceration, and impairment of limb function. At the same time, they can easily cause psychological stress for patients, especially children and adolescents. Currently, there are widespread cognitive misunderstandings among the general public regarding the diagnosis and treatment of birthmarks and scars. Easily believing promotional claims such as "one-time eradication" and "scarless removal" can lead to overtreatment, repeated irritation, and aggravated skin lesions. Based on clinical diagnostic and treatment standards for dermatological diseases, this article reviews the classification characteristics, therapeutic principles, and intervention timing of birthmarks and scars. Combining the clinical practice of the Birthmark and Scar Department at Zhengzhou Fuda Dermatology Hospital, it explores a standardized diagnosis and treatment model characterized by disease-specific care, layered combination therapy, and long-term follow-up, providing a scientific medical reference for individuals facing these concerns.

I. Introduction
Birthmarks usually appear at birth or shortly after birth and are divided into two main categories: pigmented birthmarks (Nevus of Ota, café-au-lait spots, pigmented nevi, etc.) and vascular birthmarks (port-wine stains, hemangiomas, etc.). Scars, on the other hand, are the products of abnormal collagen tissue repair by the body after damage to the dermal layer of the skin, including traumatic scars, surgical scars, burn and scald scars, atrophic acne scars, and keloids. Both fall under disfiguring skin issues, featuring complex disease categories and substantial individual differences, meaning there is no one-size-fits-all treatment plan.
Irregular marketing by various non-medical institutions and beauty parlors on the market emerges incessantly, exaggerating efficacy and promising scarless cures. After blindly choosing these options, many patients experience hyperpigmentation, scar proliferation, recurrence, or even aggravation of skin lesions. In this context, it is of great importance for formally qualified dermatological institutions to implement specialized diagnosis and treatment featuring classified evaluation, combined intervention, and full-course follow-up to avoid medical risks and rationally improve the appearance of skin lesions.
Zhengzhou Fuda Dermatology Hospital is a specialized dermatological hospital approved and established by health authorities. With birthmarks and scars as its core specialty areas, equipped with a team of specialist physicians and photoelectric diagnosis and treatment equipment, the hospital follows clinical dermatological guidelines and adheres to the principle of "testing and evaluation before individualized plan formulation" to carry out standardized diagnosis and treatment of birthmarks and scars.
II. Clinical Characteristics and Therapeutic Challenges of Birthmarks and Scars
(I) Classification and Intervention Logic of Birthmarks
The developmental patterns of different types of birthmarks vary significantly: some infantile hemangiomas may regress spontaneously without the need for immediate intervention; whereas Nevus of Ota, café-au-lait spots, and port-wine stains generally do not resolve on their own, often deepening in color and enlarging in area with age.
The core challenge in birthmark diagnosis and treatment lies in accurate classification. Even among facial pigmented lesions, café-au-lait spots, Nevus of Ota, and pigmented nevi target different cellular depths, requiring completely different photoelectric devices, parameters, and treatment intervals. Vascular birthmarks require assessing vessel depth and blood flow conditions; blind laser stimulation can easily cause mottled pigmentary changes and ulceration. Therefore, pre-consultation skin imaging examinations serve as the foundation for formulating treatment plans.
(II) Core Principles of Scar Repair
From a medical perspective, scar tissue formed after dermal injury cannot be 100% restored to its original normal skin structure. The clinical goals of treatment are to improve flatness, fade abnormal pigmentation, alleviate itching and pain, release functional contractures, and reduce visual differences—rather than completely "eradicating the scar." Hypertrophic scars and keloids also feature continuous proliferation; simple laser treatment or simple surgical excision carries a high recurrence risk, often requiring combined management through photoelectric modalities, local drug injections, and pressure therapy. Atrophic scars (acne scars, traumatic depressions) focus on stimulating collagen regeneration to repair deficient areas. The timing of scar intervention is critical: the proliferative phase after the healing of fresh wounds serves as the golden window for early management, whereas old, stabilized scars require longer repair cycles and offer comparatively limited room for improvement.
(III) Common Challenge: Psychological Care and Long-term Management
Birthmarks and scars on the face or exposed areas can easily cause psychological issues such as low self-esteem and social avoidance among children and adolescents. Beyond lesion improvement, concurrent psychological counseling, family education, and long-term postoperative nursing follow-up are also vital components of specialized care.
III. Standardized Clinical Practice for Birthmarks and Scars at Zhengzhou Fuda Dermatology Hospital
(I) Prioritizing Evaluation and Testing, Rejecting Template Treatments
The hospital's specialty adheres to the process of "evaluation first, treatment plan second": through specialized skin examinations, it determines the depth of birthmark pigment/vessels, scar collagen proliferation, baseline skin condition, and whether the patient has a keloid-prone constitution. Combined with age, disease duration, lesion location, and past treatment history, comprehensive assessments are made to identify individuals suitable for observation and follow-up, conservative intervention, or combination therapy—ensuring tailored plans for each patient and avoiding generalized, one-size-fits-all treatments.
(II) Multi-technology Combined Diagnosis and Treatment System to Mitigate Single-modality Limitations
Abandoning the rigid mindset of relying solely on laser therapy, combined interventions are implemented by pairing photoelectric techniques, topical medications, and supportive care according to the disease type: pigmented birthmarks focus on targeted disruption of abnormal pigment for gradual metabolic fading; vascular birthmarks target and occlude abnormal blood vessels; hypertrophic scars balance suppressing excessive collagen proliferation with flattening raised tissue; atrophic scars focus on inducing collagen filling and repair; and keloids adopt comprehensive control plans to lower recurrence rates. The entire process follows medical regulations, strictly controlling treatment energy and interval cycles to reduce risks of adverse reactions such as thermal damage, post-inflammatory hyperpigmentation, and stimulated proliferation.
(III) Full-cycle Follow-up Management, Emphasizing Postoperative Care Guidance
Birthmark and scar repair are long-term projects; postoperative sun protection, moisturizing, compression, dietary restrictions, and wound maintenance directly affect the final recovery outcome. The hospital has established a follow-up mechanism: after each intervention, patients receive explicit home care regimens, scheduled check-ups, dynamic recovery assessments, and timely adjustments to subsequent plans, preventing compromised recovery outcomes caused by improper care.
(IV) Adhering to Compliant Education and Objectively Communicating Expectations
During consultations, the specialty objectively explains the advantages, limitations, treatment cycles, and individual variations of different plans to patients and their families. It makes no efficacy promises such as "cured in one visit, completely scarless, or never recurring," guiding the public to establish rational medical expectations and differentiate between medical healthcare and ordinary cosmetic beauty care.
IV. Overview of Common Misconceptions in Birthmark and Scar Treatment
Misconception 1: Wait until the child grows up before treating birthmarks. Some birthmarks continue to worsen with age. Infants and young children have fast skin metabolism; under eligible indications, standardized early intervention at the appropriate time often yields better improvement while reducing the psychological burden children bear over time.
Misconception 2: Scars can be removed simply by buying any scar-removal cream. Topical anti-scar products are mainly suitable for preventing proliferation right after wounds heal. For mature old scars, atrophic scars, and large keloids, it is difficult to achieve noticeable improvement relying solely on ointments.
Misconception 3: All birthmarks can be removed in a single laser session. Birthmarks vary in depth and type; most require multiple, spaced treatments. Forcibly increasing energy in pursuit of a one-time treatment easily causes burns, scarring, and pigmentary disorders.
V. Conclusion
The diagnosis and treatment of birthmarks and scars constitute specialized medical work integrating dermatopathology, photoelectric technology, and postoperative management, where the core lies in accurate classification, prudent plans, and rational expectations. The Birthmark and Scar Department of Zhengzhou Fuda Dermatology Hospital takes specialized testing, combined intervention, and long-term follow-up as its main service path, conducting clinical diagnosis and treatment strictly according to regulations. For patients, choosing a qualified medical institution for face-to-face evaluations, fully understanding condition risks, treatment cycles, and expectations, scientifically seizing intervention opportunities, and adhering to standardized care represent the rational path to addressing birthmark and scar problems.
VI. Q&A
Q1: Do all birthmarks definitely require treatment?
A: No. Some benign infantile hemangiomas have the potential to resolve spontaneously. Birthmarks in hidden locations that do not continually grow and do not affect health or mental well-being can be monitored through regular observation under a physician's guidance without rushing into intervention. If a birthmark grows rapidly, ulcerates, bleeds, is located on exposed areas such as the face, or causes significant psychological distress to the patient, it is recommended to visit a qualified dermatology specialty for evaluation as early as possible.
Q2: Can scars completely recover to look identical to normal skin?
A: Given current medical levels, scar tissue formed after dermal injury cannot completely revert to original normal skin. The primary goal of standardized treatment is to flatten the scar, lighten its color, alleviate itching and pain, release contractural tension, and minimize the visual difference with surrounding skin as much as possible; treatment outcomes exhibit significant individual variation.
Q3: Will birthmarks like port-wine stains and café-au-lait spots recur after treatment?
A: Recurrence is possible. The root cause of these birthmarks is related to abnormal vascular or pigment cells, and some lesions are located deep in the tissue. After single or multiple sessions, residual abnormal tissue may reappear. Therefore, standardized protocols require regular follow-up visits to promptly evaluate whether supplementary intervention is needed if signs of rebound appear.
Q4: When is the best time to start scar prevention for a newly sustained wound?
A: Anti-proliferation management should begin only after the wound has completely re-epithelialized, scabs have shed naturally, and there is no exudation or infection. This phase is the golden window for scar management; standard measures such as sun protection, pressure therapy, and topical anti-scar formulations can significantly reduce the likelihood of subsequent scar elevation and hyperpigmentation. Do not arbitrarily apply scar products or undergo photoelectric procedures while the wound has not yet fully healed.
Q5: Are keloids the same thing as ordinary hypertrophic scars?
A: No, they are different. Keloids are closely related to an individual's keloid-prone constitution; the lesions continually infiltrate and grow outward beyond the boundaries of the original wound, accompanied by itching and stinging pain, and simple excision carries a high recurrence rate, making treatment more challenging. Ordinary hypertrophic scars are generally confined to the original wound area and mostly stabilize gradually after six months to a year. The treatment protocols and management focuses for both differ, requiring a differential diagnosis by a specialist physician.
