What should you know about er yag fractional laser?

Fractional delivery divides the beam into many small treatment zones rather than treating the whole surface as one continuous field. Untreated skin between the columns can help support repair, while the treated columns address texture. Clinicians may consider this approach for acne scars, fine lines or uneven surface quality. Results and recovery vary with energy, density, body site, skin colour, scar type and whether other treatments are combined.

Before treatment, tell the clinician about active acne or infection, cold sores, recent sun exposure, medicines and any tendency to develop dark marks after inflammation. Afterwards, expect temporary redness, warmth, swelling or flaking. Use only the recommended cleanser and moisturiser, avoid picking, and protect healing skin from sunlight. Read about [Fractional Laser](/technology/fractional-laser/) and [Fractional Laser Treatment](/treatments/laser-and-energy/fractional-laser-treatment/) for related information; [Acne Scar Laser Treatment](/treatments/laser-and-energy/acne-scar-laser-treatment/) covers one common indication.

Ask the clinic for prompt review if pain, swelling, redness or warmth is intensifying, or if you notice pus, fever, extensive blistering, unexpected bleeding or slow healing. Follow-up is also useful if the treated area develops a new persistent colour change. Avoid acids, retinoids and abrasive products until your aftercare instructions allow them.

Is fractional Er:YAG suitable for my scar or texture concern? What depth and density will you use, how many visits might be considered, and how will you reduce irritation or unwanted pigment change during healing?
