Thulium Laser — Skin Resurfacing

The Thulium laser at Petra Clinic is a fractional non-ablative laser that creates thousands of microscopic thermal columns through the full dermis without removing the overlying epidermis — a technique called micro-channelling. Each channel triggers a localised healing response that replaces damaged collagen with new organised fibres, improving pigmentation, acne scars, stretch marks, uneven texture and fine lines. Because the epidermis remains intact, recovery is substantially faster than with ablative fractional lasers: clients typically manage four to five days of mild flaking. The thulium wavelength (1927 nm or similar) is absorbed strongly by water in the dermis and penetrates to mid-dermis depth, making it suitable for year-round use with appropriate photoprotection.
