Air subcision + Juvelook injector

It is an 'air subcision' treatment: a fine needle releases a short burst of CO2 gas to loosen the fibrous tethering that pulls a scar down from beneath the skin. The same device can then deliver a regenerative ingredient such as Juvelook into the released space, so lifting the scar base and filling that space happen together.

Regular subcision cuts the tethering by moving a needle or cannula beneath the skin. Air subcision opens the gap between the bands with gas pressure at the point where the needle is placed, which makes it well suited to treating scars one by one in short steps. Which one suits you depends on the depth and extent of your scars, and for broadly tethered scars we sometimes use regular subcision as well.

If the tethering is only released, it can re-adhere during healing or the scar base may not rise enough. Juvelook breaks down slowly and helps collagen form around it, so placing it in the released space helps fill that space with new tissue. It is not used for every scar; we decide which areas need it at consultation.

If a scar fades when you gently stretch the surrounding skin, it is likely tethered underneath. Air subcision suits gently sloping rolling scars and scars with a broad base, while narrow, deep icepick scars are handled with other treatments. Most faces have a mix of scar types, so we choose a method for each scar at consultation.

We start with numbing cream and add anesthesia depending on the extent of the scars. You may feel a brief pressing sensation or dull ache as the gas enters. Everyone feels it differently, so please tell us right away if you are uncomfortable during treatment.

The treated area swells, and bruises can appear where the needle went in. These usually settle within a few days to 1–2 weeks, and face washing and light daily activities are generally possible from the next day. If you have an important event coming up, let us know at consultation so we can plan the timing together.

It depends on the depth and number of scars, but rather than a single session, several sessions 1–3 months apart are often planned. At each session we reassess the remaining scars to decide the next step, and we sometimes schedule surface treatments such as lasers in sequence.

Once the swelling goes down, you may see the scar base sitting a little higher, but it is too early to judge the result from that alone. The real change appears gradually over weeks to months as new collagen forms, and the speed and degree vary from person to person.

Swelling, bruising and tenderness are common, and when a regenerative ingredient is injected, a small lump (nodule) can rarely be felt. Please be sure to tell us at consultation if there is inflamed acne or infection in the area, if you are pregnant or breastfeeding, if you take anticoagulants, or if you are prone to keloids.

The cost depends on the extent of the scars, the number of sessions and whether a regenerative ingredient is used, and is confirmed after examination. Non-covered treatment fees can be found on the pricing page of our website.
