Is Laser Skin Resurfacing Painful? What UltraPulse Treatment and Recovery Feel Like

Clinical guidance from Dr Nyla Raja MBChB (Hons), MRCGP (Dist), DFFP, DPDermatology - GMC No. 6057913

Laser skin resurfacing can be uncomfortable, but appropriate anaesthetic measures are used to help make treatment manageable. During fractional CO2 treatment, patients may describe warmth, heat, or a prickling sensation. Comfort varies between individuals, and a more intensive treatment plan may feel stronger during treatment and in the first few days of recovery.

At Dr Nyla Medispa, UltraPulse CO2 Laser Skin Resurfacing is tailored to the concern being treated, such as acne scarring, deeper lines, sun damage, pigmentation, or uneven texture. Treatment depth, coverage, the area treated, and individual skin factors can all influence how the procedure and healing process feel.

What does laser skin resurfacing feel like during treatment?

After the anaesthetic has taken effect, you may still notice the laser working. The sensation is commonly described as brief pulses of heat, warmth, or prickling as the handpiece moves over the skin. Some areas can feel more noticeable than others, so it is important to tell your practitioner if discomfort is difficult to manage.

UltraPulse is a fractional CO2 laser. Rather than treating the whole skin surface in one continuous layer, it creates controlled microscopic treatment zones while leaving surrounding skin intact. Treatment time varies according to the size of the area and the personalised plan.

Fractional CO2 resurfacing can involve more sensation than gentler, non-ablative skin treatments because it creates a controlled skin-healing response. Anaesthetic choice and treatment settings should be planned around the area, treatment intensity, and individual patient. NHS CO2 laser guidance notes that topical and/or local anaesthetic may be used to support comfort during treatment. Read Queen Victoria Hospital NHS Foundation Trust’s CO2 laser patient guidance.

Why treatment intensity affects comfort

Laser resurfacing is not one fixed experience. A lighter treatment intended to refresh texture or address more superficial change may involve less downtime than a deeper plan for established wrinkles or textural scarring. A more intensive approach may provide a greater resurfacing effect where clinically appropriate, but it also tends to involve more redness, swelling, sensitivity, and visible healing afterwards.

Does laser resurfacing hurt afterwards?

Post-treatment discomfort is usually temporary and tends to be most noticeable shortly after treatment and over the first few days. The skin may feel hot, red, swollen, tight, sensitive, dry, or tender. As healing progresses, dryness, flaking, peeling, and light crusting can occur.

The visible initial recovery period after fractional CO2 resurfacing is often around a week, although redness and sensitivity can last longer, particularly after a more intensive treatment. It is sensible to plan social downtime and follow the written aftercare provided for your own treatment. Our detailed guide to laser skin resurfacing recovery explains the expected stages in more detail.

Use only the cleansing and healing products advised for you, and avoid picking, scrubbing, exfoliating, or introducing active skincare while the skin barrier is recovering. Sun protection is an essential part of aftercare once your clinician confirms that sunscreen can be applied. Recent tanning, sun exposure, and a history of pigment change after inflammation are important to discuss before treatment.

What is normal, and when should you seek advice?

Redness, swelling, sensitivity, peeling, and a small amount of clear or pale straw-coloured fluid shortly after CO2 treatment can occur during normal healing. These symptoms should gradually settle rather than become more severe.

Contact your treating practitioner promptly if you develop increasing pain, redness, warmth, or swelling; spreading redness; thick, cloudy, yellow, or green discharge; new blisters; a worsening rash; or an area that does not appear to be healing. Fever or feeling generally unwell requires urgent medical advice. These symptoms do not necessarily mean there is a complication, but they should be assessed without delay. NHS guidance similarly highlights excessive redness, heat, swelling, and a change in fluid or pus leakage as signs requiring clinical contact. See University Hospitals Birmingham NHS guidance on CO2 laser aftercare.

Tell your practitioner before treatment if you have a history of cold sores, an active skin infection, a rash, recent tanning, or current or recent isotretinoin use. These details can affect whether treatment is appropriate at that time and how your plan is prepared.

How to prepare if you are concerned about pain

• Discuss your concerns openly at consultation, including previous experiences with dental work, injections, lasers, or other procedures.
• Ask what type of anaesthetic is planned, when it will be applied, and what sensations are realistic for your treatment area.
• Arrange a quiet journey home and avoid scheduling important events during the early healing phase.
• Follow preparation advice carefully, including guidance on sun exposure and skincare products.
• Do not take or stop medication, including pain relief or prescribed skincare, unless your treating clinician or prescriber has advised you to do so.

The key point

Laser skin resurfacing can be uncomfortable, but UltraPulse treatment is performed with anaesthetic measures intended to make it manageable. Many patients experience warmth or prickling during treatment, followed by temporary heat, tightness, redness, and sensitivity as the skin heals. The important consideration is whether the treatment intensity, comfort plan, and recovery period are appropriate for your skin, goals, and lifestyle.
