Laser Skin Resurfacing Recovery: What to Expect Before, During and After Treatment

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

Recovery after laser skin resurfacing is a planned part of treatment, not an afterthought. Following fractional CO2 resurfacing, it is normal for skin to feel hot, red, swollen, sensitive, and then dry or flaky as it heals. For many patients, the visible initial recovery period is around one week, although residual redness and sensitivity can last longer, particularly after a more intensive treatment.

UltraPulse CO2 Laser Skin Resurfacing is a fractional treatment, meaning it creates precise microscopic treatment zones while leaving surrounding skin intact. This can support a more controlled healing process than traditional fully ablative resurfacing, but it still requires careful preparation, personalised aftercare, and diligent sun protection.

How long does laser skin resurfacing recovery take?

The recovery timeline depends on the treatment area, the intensity and depth of treatment, your skin type, your underlying concern, and how your skin heals. Treatment for deeper acne scarring or more pronounced textural change may involve more downtime than lighter resurfacing.

These are broad guideposts, rather than a promise of exactly how your skin will look on a particular day. Published NHS guidance for CO2 laser treatments also notes that treated skin can remain red and sensitive for several weeks, while the initial surface healing is much earlier. Read the University Hospitals Birmingham NHS guidance on CO2 laser aftercare.

Preparing for laser resurfacing

Good preparation helps reduce avoidable irritation and allows your practitioner to assess whether treatment is appropriate at that time. At your consultation, disclose all medicines, supplements, allergies, previous reactions to treatments, and relevant medical history. In particular, mention a history of cold sores, changes in your skin, active rashes or infections, and recent or current use of isotretinoin.

Avoid tanning, including fake tan, before treatment, and protect the area from ultraviolet exposure. Recent sun exposure can increase the risk of an uneven pigment response after laser treatment. Your practitioner may also advise you to pause potentially irritating skincare, such as retinoids or exfoliating acids, for a specified period. Do not stop prescribed medication unless the clinician responsible for your care advises this.

It is sensible to schedule downtime, avoid important social commitments during the initial healing phase, and arrange practical help if a larger facial area is being treated. Your clinician will explain the expected treatment duration and the appropriate anaesthetic options for your treatment plan.

What to do after laser skin resurfacing

Your written instructions from the treating clinician always take priority over general online advice. The treated skin has a temporarily disrupted barrier, so the aim is to keep it clean, protected, and free from unnecessary irritation while it repairs.

Keep skincare deliberately simple

Use the cleanser, moisturising or healing products, and application method advised for you. Avoid introducing new skincare, active ingredients, fragranced products, facial scrubs, exfoliating acids, retinoids, or at-home devices until your practitioner confirms that the skin barrier has recovered.

Do not pick at peeling skin, flaking, or crusting. Removing it prematurely can prolong healing and may increase the chance of irritation, infection, or unwanted pigment change.

Protect healing skin from sun exposure

Sun avoidance is particularly important after resurfacing. Once your clinician advises that sunscreen can be applied, broad-spectrum SPF may form part of your aftercare plan. UV exposure can worsen inflammation and contribute to post-inflammatory hyperpigmentation, especially in skin that tans easily or has previously developed pigmentation after inflammation. The intensity of treatment, skin type, recent sun exposure, and previous pigment response all influence risk.

Use the sun-protection plan provided for you, which may include avoiding direct exposure, seeking shade, and wearing protective clothing or a hat. For context, NHS aftercare guidance advises high-factor protection after laser treatment to help reduce the risk of sunburn and pigment changes.

Give exercise, heat, and make-up time

Heat, sweating, swimming, saunas, steam rooms, and vigorous exercise can aggravate freshly treated skin. Avoid them for the period advised in your aftercare plan. Likewise, do not apply make-up until your clinician confirms that the skin has healed sufficiently. If you need to return to work before redness has fully settled, ask when a suitable, non-irritating cover product can be used safely.

What is normal, and when should you contact your clinician?

Redness, swelling, tenderness, sensitivity, dryness, and peeling are expected features of recovery. A clear or pale straw-coloured fluid can also occur soon after CO2 treatment. These changes should gradually settle rather than become increasingly severe.

Contact the treating clinic promptly if you develop increasing rather than improving redness, warmth, swelling, or pain; thick, cloudy, yellow, or green discharge; spreading redness; new blisters; a rash that is worsening; or a delayed 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 need timely assessment.

If you have a history of cold sores, tell your practitioner before treatment. Laser resurfacing around the mouth can reactivate herpes simplex in some people, and antiviral treatment may be considered as part of an individual treatment plan. Evidence-based supportive skincare guidance also highlights the importance of antiviral planning for invasive resurfacing around the mouth and strict photoprotection during recovery. See the European dermatology consensus guidance on supportive skincare around aesthetic procedures.

Recovery and results are not the same thing

Initial healing tells you that the surface of the skin is repairing; it does not represent the final result. Fractional CO2 laser treatment is used to support gradual collagen remodelling, so improvements in skin texture, fine lines, sun damage, pigmentation, and selected scars may continue to develop over the following weeks and months.

It is important to allow the skin to settle before judging the outcome. Results vary according to the concern treated, treatment intensity, individual healing, age, medical history, lifestyle, and ongoing sun exposure.

The key point

Laser skin resurfacing recovery usually involves around a week of visible healing, followed by a longer period in which redness settles and collagen remodelling develops. The safest approach is to plan downtime, protect the skin from sun exposure, use only the recommended aftercare, avoid picking or irritating skincare, and contact your treating clinician promptly if symptoms are worsening rather than improving.
