Scar Treatment — Laser and LED

Treatment of fresh and mature scars — including surgical, traumatic, acne and hypertrophic scars — using a combination of FOTONA 4D fractional laser and LED phototherapy. Fractional laser creates controlled micro-channels in the scar tissue that stimulate new collagen synthesis, gradually replacing abnormal scar collagen with more organised fibres and improving texture and colour. LED phototherapy modulates inflammation and accelerates healing between sessions. MUDr. Helena Závodská selects the protocol based on scar type, age and location.

Scars form when the wound healing process produces collagen in a disorganised pattern, resulting in tissue that differs from normal skin in texture, colour, elevation and elasticity. Different scar types require different approaches: atrophic scars (common in acne) are depressed below the surrounding skin surface due to collagen and tissue loss; hypertrophic scars are raised but confined to the original wound margin; keloids extend beyond the wound boundary; and surgical scars vary widely in quality depending on wound closure technique, location and individual healing response. At AE Derm MUDr. Helena Závodská addresses scars using the fractional Er:YAG mode of the FOTONA 4D system. The fractional approach creates thousands of microscopic ablation channels through the epidermis and into the papillary and upper reticular dermis of the scar tissue; the heat and microtrauma at each channel boundary initiates a fresh wound-healing cascade, generating new, more normally organised collagen within the scar. The surrounding intact tissue between channels heals rapidly, reducing downtime compared to fully ablative treatment of the entire scar surface. For fresh scars — within the first three to six months of formation, when the tissue is still remodelling — even conservative fractional treatment can significantly redirect healing. For established mature scars, typically several sessions spaced four to eight weeks apart are required to achieve meaningful textural and colour improvement; complete resolution is rarely achievable but substantial improvement is typical with consistent treatment. LED phototherapy is used between laser sessions and immediately after each session as an anti-inflammatory and healing modulator. Red and near-infrared LED wavelengths reduce post-treatment redness, accelerate epidermal recovery between fractional treatment sessions and provide ongoing collagen-stimulating effects through photobiomodulation. For hypertrophic scars or keloids, intralesional treatment options may also be discussed at consultation depending on lesion characteristics. Stretch marks (striae distensae) are treated using the same combination: fractional laser addresses the atrophic, collagen-depleted zone of the striae while LED phototherapy supports the healing and collagen remodelling response. Results for striae are gradual and most visible after a course of four to six sessions.
