Non-Ablative Laser Skin Tightening

Non-ablative laser tightening works through controlled dermal heating rather than surface removal. The Nd:YAG 1064 nm wavelength penetrates to the mid and deep dermis and the superficial fibromuscular layer without disrupting the epidermal surface. The heat energy denatures existing collagen fibres, causing immediate contraction and a tightening response; in the weeks following this initial response, fibroblasts produce new, denser collagen to replace and…

At AE Derm MUDr. Helena Závodská uses the PIANO mode of the FOTONA 4D system for bulk dermal heating — a continuous scanning technique that delivers energy evenly across the treatment zone rather than in discrete pulses, maintaining the target tissue in a controlled temperature range that is therapeutic for collagen but below the threshold of ablation or scarring. This mode is particularly effective for the lower face, jaw and neck, where gravity-related…

Immediately after the session the skin may appear flushed and slightly swollen; this typically resolves within a few hours. There is no peeling or surface damage. The tightening response develops gradually — initial improvement in skin tone is often noticeable within a few days as denatured collagen contracts, with the full collagen remodelling response maturing over two to four months. A course of three to four sessions spaced three to six weeks apart…
