Acne Treatment — DermaPen and Excimer Laser

Acne vulgaris involves four interacting pathological processes: follicular hyperkeratinisation (the plug), colonisation by Cutibacterium acnes, excess sebum production and the resultant inflammatory cascade. Effective treatment typically needs to address at least two or three of these simultaneously, which is why single-modality approaches often provide only partial response.

At Derma Medical Clinic the structured acne treatment protocol uses DermaPen and XTRAC excimer laser in a sequenced, cycling approach. The DermaPen component at acne-appropriate depths (0.5–1.5 mm) opens the follicle, disrupts the hyperkeratinised plug, and creates a controlled micro-injury response that shifts the follicle environment from an infection-prone blocked state towards active healing. Applied with an acne-specific mesoglide serum — typically…

Two weeks after each DermaPen session, the XTRAC 308 nm excimer laser component begins: two weeks of laser sessions (three times per week) deliver UV energy that generates reactive oxygen species within C. acnes bacterial cells, producing photodynamic antibacterial effects, and simultaneously suppresses the inflammatory T-lymphocyte activity driving papule and pustule formation. For patients with inflammatory acne, the combination of these two mechanisms…
