How does it work?

A laser with a 10,600 nm wavelength can target very small areas while emitting a very short pulse preventing unnecessary damage to the normal surrounding skin. Since this laser can be adjusted and customized, it is utilized in procedures requiring precise accuracy.

The laser is an ABLATIVE laser meaning it will burn whatever it comes into contact with. Therefore “burning away” of certain skin lesions on the surface of the skin is possible.

*Whether the lesion you are keen to treat with CO2 laser is treatable or not at AEON will be determined by the doctor and may not be treatable at AEON. This is the sole discretion of the doctor at AEON. You may be referred to another institution for further evaluation.

Is CO2 laser painful?

Due to it being an ABLATIVE laser, there is pain involved and therefore it is advisable to apply a topical anesthetic cream before the procedure. Even though this cream is applied, there can still be pain during the procedure especially the deeper the lesion is.

What can I expect during my treatment?

Your eyes will be first be protected with metal goggles. Then our doctor will begin treatment, by gently applying the laser energy to your skin with part of the handpiece making physical contact with your skin. You will feel some heat and mild prickling sensations during the laser. There is also a slight “burning smell” which is the lesion and skin cells absorbing the laser energy and being “burnt away”. Depending on the size and depth of the lesion the length of the procedure may differ.

Is there any downtime? What aftercare do I need?

There is NO downtime in the sense of having to take leave and/or stay indoors after the procedure. Due to it being an ABLATIVE laser, there will be depression or “crater” where the lesion previously was. There is no special aftercare needed in terms of topical applications, but to facilitate healing, a thin hydrocolloid dressing sticker will be applied onto the treatment site. You will be provided with extra “stickers” to change every 2 days until the skin has “filled up” or “levelled out”. This can take 3 days to 2 weeks depending on the depth of the lesion and individual differences. You can apply makeup on top of this sticker, wash your face and shower with the sticker on.
You may experience some redness and swelling around the treatment area that should resolve within a few hours but may last 2-3 days. Again, there is no requirement for you to stay indoors or avoid cosmetic application afterwards. You are able to return to work, apply makeup and resume most of your activities immediately. Please avoid exercise 1-2 days before and at least 2 weeks after the treatment during the healing process.

One of the most important thing to avoid is UV radiation from sun exposure. Especially immediately after the procedure, but even weeks or months after the procedure, it is advised to avoid excessive, prolonged sun exposure even with sunblock applied. Depending on your skin condition and sun exposure, you may develop darker pigmentations in the treatment areas. You are advised to apply sunblock every 1-2 hours when outdoors and avoid outdoor exposure especially during the peak sunlight hours of the day.

How many treatments will I need?

Recurrence of lesions treated with CO2 lasers are very common. The timing of recurrence can be within months of the treatment or years afterwards. Repeated treatment can be considered, but repeating a CO2 ablative laser on the same site can increase the risk of side effects listed below.

What are some of the CO2 laser side effects?

Due to this laser being ABLATIVE, there are more possible side effects to take into consideration compared to the other NON-ABLATIVE lasers.

First of all, you must be aware that there are options of laser(non-surgical) and surgical treatment for these types of lesion(s). Surgical treatment (excisional biopsy) has the advantage of very low recurrence and potential for being able to send the lesion for biopsy (confirmation diagnosis) if needed. Whereas laser treatment has higher risk of recurrence and no possibility to confirm the diagnosis as the lesions will be ablated (“burned away”). Worst case scenario by doing a CO2 laser treatment for a skin lesions is that a more serious condition such as a malignancy (cancer, pre-cancer) might be missed.

Possible side effects and complications of the CO2 laser treatment are as follows:

  • Pain: Numbing cream can be applied if desired to lessen the burning sensation of the laser which can be minimal to moderate.
  • Swelling:  The area can have some swelling for 1-2 days especially around the eye areas. The swelling will subside without any additional treatment.
  • Bleeding: There may be mild bleeding for 1-2 days but if bleeding continues, please contact us or see a doctor as soon as possible.
  • Depressed scars (“craters”):  Some areas may not heal completely and therefore leave a depression in the treated area which is permanent.
  • Elevated scar:  Some areas may heal in a manner where the skin grows more than originally present forming a “hump” or larger “hump” which is permanent.
  • Infection:  Persisting pain, swelling, discharge, pain and fever could indicate an infection in which case topical and/or oral antibiotics may be needed after seeing a doctor. Wound healing could be compromised in this situation and wound complications may be more evident. This is rarely seen.
  • Erythema:  Immediately after treatment, the skin area treated will be a red color which usually eventually gradually normalized over the next few months. There are cases where the redness can be permanent.
  • Skin darkening (hyperpigmentation):  The darker your skin tone and the more sun exposure you receive can cause the treated are to have a dark color which can be permanent.
  • Skin lightening (hypopigmentation):  Areas treated other than the face can leave a whitish spot especially if the surrounding skin is darker. This is permanent.
  • Recurrence:  The lesion can recur anytime from immediately after healing to many years later. Repeated treatment by laser on the same site can lead to more risk of scarring or other complications listed above.
  • Remnant:  The lesion may be so deep that the lesion cannot be completely removed during one session. After healing the area can be assessed whether to do another session of treatment.
