At Cosmedicon 2025, Dr Cosima Karlburger presented new insights into rosacea management for patients with skin of colour, focusing on developments in energy-based treatment approaches. The session explored how emerging laser technologies may support practitioners in safely treating a broader spectrum of skin types, including those traditionally underserved by standard protocols.
Drawing on her clinical experience and collaborative work with US-based board-certified dermatologist Dr Cheri Frey, Dr Cosima shared her experience using the 650 microsecond 1064nm Nd:YAG laser in patients with higher Fitzpatrick skin types.
Understanding Rosacea in Diverse Skin Types
Rosacea can present differently in darker skin tones, making early diagnosis and management more complex. Common signs such as redness and flushing are often less visible due to increased melanin, which can delay appropriate treatment. Patients may report sensations of warmth, product sensitivity, or persistent breakouts that may be misinterpreted as acne rather than inflammation.
Dr Cosima highlighted the importance of recognising these variations and adopting technology that enables safe and individualised care.
Energy-Based Devices and Skin Safety
The presentation emphasised the role of pulse duration and wavelength in treatment safety and efficacy. Dr Cosima explained how the 650 microsecond short-pulse technology offers greater precision and reduced heat diffusion, making it suitable for patients at risk of post-inflammatory pigmentation or sensitivity.
A case study involving a Fitzpatrick type V patient showed promising improvements in visible inflammation following three sessions spaced three weeks apart. Although individual results vary, the approach illustrates how selecting the right modality can contribute to tailored care.
Key Takeaways from Dr Cosima’s Presentation
- Rosacea in skin of colour often presents with less visible erythema and more textural or sensory symptoms.
- Traditional therapies may not be suitable for all skin types, particularly where pigmentary risk is a concern.
- Emerging laser technologies offer new avenues to support clinical decision-making and patient comfort.
- Collaboration and education are critical to advancing safe, inclusive care in aesthetic medicine.
“Understanding how rosacea appears across the full spectrum of skin types is essential,” Dr Cosima noted. “Technology is only part of the solution. We must also stay curious, reflective, and inclusive in our clinical approach.”
Dr Cosima’s work continues to explore how non-surgical technologies can support skin health when used in conjunction with personalised care and professional evaluation.
