Scar Reduction & Removal

Aaron Laser takes a physician-led, modality-matched approach to scar treatment — selecting from fractional and surgical CO2 laser, cryotherapy, biostimulation laser, and silicone gels and patches depending on the scar type. Hypertrophic and keloid scars (raised, firm tissue) respond to cryotherapy and biostimulation laser that soften and reduce the scar bulk. Atrophic scars (sunken, such as post-acne icepick or rolling scars) respond to fractional CO2 laser resurfacing and microneedling that drive collagen formation from below. Post-surgical and traumatic scars may require a combination approach. The dermatologists at Aaron Laser are members of the Czech Laser Society and bring specialist training to laser parameter selection for scar indications.

Scar remodelling is one of the more technically demanding areas of aesthetic dermatology because the same scar morphology — hypertrophic, keloid, atrophic or mixed — can behave very differently depending on its aetiology, age, skin type and location. At Aaron Laser, a dermatovenereology specialist assesses each scar individually and designs a treatment protocol around the clinical presentation rather than applying a standard algorithm. The clinic's scar treatment toolkit spans four main modalities. Fractional CO2 laser (COSCAN system) is the primary tool for atrophic scars such as post-acne icepick, rolling and boxcar scars: the fractional ablation columns trigger deep fibroblast activation, driving new collagen formation from the base of the scar upward and progressively filling in the depression. Multiple sessions are typically required, spaced 6–12 weeks apart to allow full collagen maturation between treatments. Biostimulation laser (LLLT) is used for post-surgical or traumatic linear scars in the acute or subacute phase: the photobiomodulatory effect accelerates fibroblast migration and collagen cross-linking during the active remodelling window, potentially reducing final scar visibility. Cryotherapy — applied as a controlled freeze to raised scar tissue — is a recognised treatment for hypertrophic scars and smaller keloids: repeated freeze-thaw cycles damage the abnormal fibrous tissue and reduce scar bulk. Silicone sheeting and gels (available at the clinic as a supportive adjunct) are the evidence-based standard for prophylactic prevention of hypertrophic scarring in fresh wounds and early scars. For complex or keloid scars, the physician may recommend combined treatment or refer to a specialist facility for intralesional corticosteroid injection. All laser parameters are set by physicians who are members of the Czech Laser Society, ensuring specialist-level knowledge of the interaction between specific laser wavelengths and scar tissue at different Fitzpatrick skin types.
