What should you know about Sellas fractional laser?

Fractional laser energy creates controlled microscopic treatment zones in selected skin layers. The body then repairs those zones, which can gradually soften the look of acne scars, fine lines, uneven texture, or some pigment concerns. Results depend on the device settings, the target problem, skin tone, and healing response. Fractional treatment is not the same as removing the entire surface at once, but it can still cause redness, warmth, swelling, crusting, or temporary colour change.

Have a qualified clinician assess your skin, active acne, history of cold sores, tendency to form raised scars, and recent sun exposure. Follow instructions about pausing irritating products and arrive with clean skin. Afterwards, keep the area gently cleansed and moisturised, do not pick flakes or crusts, and limit heat and direct sun while the barrier recovers. Use the prescribed sunscreen and return for review if advised. Treatment planning may be discussed alongside [Fractional Laser Treatment](/treatments/laser-and-energy/fractional-laser-treatment/) or [Acne Scar Laser Treatment](/treatments/laser-and-energy/acne-scar-laser-treatment/).

Contact the treating clinic promptly for increasing pain, spreading redness, pus, fever, rapidly worsening swelling, or blisters. Urgent care is appropriate for breathing difficulty or swelling involving the lips or eyes. New or persistent dark or light patches also deserve review, especially after sun exposure.

Ask which laser wavelength and settings are proposed, what problem is being targeted, how many appointments may be considered, and what downtime is realistic for your skin. Ask about antiviral prevention, pigment-change risk, pain control, sun protection, and signs of infection.
