Before you start

  • Tell us about: recent sun exposure, cold sores, medications (including isotretinoin, antibiotics, acne topicals), supplements, pregnancy/breastfeeding.
  • Tailored prep: in some cases we’ll prescribe pre-treatment skincare or antiviral/antibiotic cover. Always follow your clinician’s instructions.
  • Plan downtime: depending on settings, expect redness/peeling. Clear your calendar and arrange transport if needed.
This guide is general information and not a substitute for personalised medical advice. Your practitioner’s plan takes priority.

Your prep timeline

2–4 weeks before

Strictly avoid tanning and sunbeds. Daily SPF 50 (reapply).
Pause retinoids (tretinoin, adapalene), AHA/BHA, benzoyl peroxide on the treatment area unless your clinician advises otherwise.
Flag any photosensitising meds (e.g., doxycycline). We’ll advise on timing.
Discuss history of cold sores (HSV-1) — prophylaxis may be recommended.

7 days before

No waxing, threading, epilating, depilatory creams or peels on the area.
Switch to a gentle routine: mild cleanser + bland moisturiser; keep skin calm.
Hydrate well and avoid new products or facials.

48–24 hours before

Avoid alcohol; unless prescribed, avoid NSAIDs (e.g., ibuprofen) that may increase bleeding risk — confirm with your clinician.
Have a clean pillowcase and gentle aftercare products ready for post-treatment.
If instructed, start any prescribed antivirals/antibiotics and pre-treatment cream.

On the day

  • Arrive with a clean face (no makeup/actives on the treatment area).
  • Bring SPF 50 and a wide-brim hat for your journey home.
  • Tell us about any new breakouts, cuts, rashes or illness.
For facial hair areas, shave only if specifically advised (usually 24–48h before); avoid close shaving on the day.

Use this pre-treatment

  • Gentle cleanser (fragrance-free)
  • Bland moisturiser (ceramides, glycerin)
  • Mineral SPF 50 (zinc/titanium), reapplied
  • Hydrating mist or hyaluronic serum (if tolerated)
Your clinician may prescribe a prep cream (e.g., lightening agents before pigment work). Use only as directed.

Avoid this pre-treatment

  • Retinoids, AHAs/BHAs, benzoyl peroxide on the treatment area
  • Scrubs/brushes, micro-needling, strong actives, new products
  • Waxing/depilatories/bleaching on area
  • Unprotected UV exposure; fake tan on the area

Frequently asked

Do I need antiviral tablets?

If you have a history of cold sores or we’re treating around lips/low face, your clinician may advise prophylaxis. Follow the schedule provided by the clinic.

Can I keep using tretinoin?

Usually stop 2–4 weeks before on the treatment area (exact timing is personalised). We’ll give you a restart schedule post-treatment.

What happens if I get sun exposure?

Tell us. We may adjust timing or settings. Sun protection before and after is essential to reduce risks of pigment change and delayed healing.

When can I resume the gym?

Typically avoid heat/sweat for a few days post-treatment (varies by settings). You’ll get a tailored aftercare plan on the day.

  • Preparation for CO2 laser treatment

This is important to ensure the best results and minimize potential complications. Please follow these guidelines carefully:

4 Weeks Before Treatment:

      1. Sun Exposure: Avoid tanning and heavy sun exposure. It is essential to protect your skin from UV damage. Use a broad-spectrum sunscreen with at least SPF 30 daily during this period.
      2. Medications: Do not use medications that can make your skin more sensitive to the sun, such as doxycycline or minocycline, for at least 3 days before your treatment.
      3. History of Herpes or Shingles: If you have a history of herpes (such as oral cold sores or genital herpes) or shingles in the treatment area, your doctor may recommend starting antiviral medication (such as valacyclovir or acyclovir) two days before treatment and continuing it for three days after treatment to reduce the risk of outbreaks.
      4. Hydration: To prevent dehydration, make sure to eat and drink adequately before the procedure.

    Day of Procedure:

        1. Clothing: Dress in comfortable, low-neck, and loose-fitting clothing. Buttoned or zippered shirts are preferred.
        2. Cosmetics and Jewellery: Do not wear makeup, jewellery, cosmetic creams, hair products, deodorant, sunscreen, or piercings on the day of your procedure.
        3. Face Preparation: Wash your face thoroughly before the treatment and refrain from applying any products to your face afterward, including lotion, sunscreen, or makeup

      Procedure Details:

      Before the CO2 laser procedure, several important steps will be taken:

          1. Consultation: You will have a consultation with your doctor to discuss the treatment and receive a prescription for prophylaxis. The doctor will organize and provide the necessary medications for your recovery.
          2. Pre-Procedure Preparation: Your doctor will see you before the procedure to prepare and clarify any questions or concerns. You will sign a consent form to authorize the procedure, and if necessary, antiviral tablets and an optional sedative will be administered.
          3. Anaesthetic Preparation: Anaesthetic preparation may include the application of topical local anaesthetic gel. In some cases, additional anaesthetic techniques such as tumescent anaesthesia or nerve blocks may be used.
          4. Procedure Duration: The CO2 laser procedure typically takes around 30-45 minutes to complete. Most patients experience a moderate level of discomfort, described as a prickly burning sensation.
          5. Post-Procedure Care: After the procedure, your face may feel very hot, similar to a sunburn sensation. A barrier cream like CU3 cream or Eucerin Aquaphor cream will be applied to protect your skin from dehydration and infection.

        Aftercare Instructions:

        Strictly follow these aftercare instructions:

            1. Face Washing: Wash your face twice daily, in the morning and before bedtime, using a gentle cleanser recommended by your doctor.
            2. Moisturizer: Apply Aquaphor or Vaseline Petroleum Jelly to maintain a moist environment on your skin for the first month.
            3. Sunscreen: Avoid sun exposure for at least two to three weeks after the procedure. Only start using sunscreen with SPF 50 as recommended by your doctor.
            4. Avoid Irritants: Do not use any other moisturizers or healing balms for three months. Avoid using silicone-based dressings.
            5. No Masks: Refrain from wearing masks for three months to prevent inflammation and scarring.
            6. Shaving: Avoid razor shaving for the first month. Use a beard trimmer tentatively after day 14.
            7. Makeup and Skincare Products: Gradually reintroduce makeup and skincare products 12 weeks after the procedure. Consult with your doctor for recommendations.
            8. Consultation and Monitoring: Attend a 3-month in-clinic review with your doctor to assess your progress and discuss your future skincare routine.

          Please adhere to these guidelines diligently to promote proper healing and achieve the best results from your CO2 laser treatment. Your doctor will provide personalized advice and monitor your recovery closely.
