Is subcision alone effective? Do scars re-tether afterward? What can be combined with subcision to be as effective as fillers?

Our treatments use combination therapy to improve the epidermis and dermis for most deep scars. The options available for acne scars depend on the character of your scars, in terms of topography and contour. We see atrophic and hypertrophic acne scars, as well as scars that have hypo and hyperpigmentation. We begin each scar evaluation with an assessment of scar quality and subtype. Our main concern is rebuilding collagen and that is why we use a HIDEF protocol that includes combination therapy. Morpheus 8, scar subcision, fibrous release, fractional laser, CO2 laser, Thulium laser, PDL Vbeam laser, and fractional resurfacing can be used in addition to TCA Cross and chemical peels to further improve skin. Patients should start Melarase AM and Melarase PM for active hyperpigmentation. Always begin with a consultation to decide whether early subcision should be started.

Published Studies have shown that adding PRP to subcision improves the results. I believe the PRP stimulates new elastin and collagen formation, remodels the scar and prevents the tethers from reforming.. It is our first choice to combine with subcision. Fillers can also prevent tethers from reforming.

First question- it depends on the scar type. Combination treatments are always based upon safety and the scar type. Second question- if scars are true atrophic and you do not have the ability to regenerate collagen, then the process may need to be repeated. Dermal grafting has its pros and cons. Subcsion was first reported in 1995. Since then this technique has taken many pathways. Most dermatologist and plastics still perform the old method- using sideways motion to break scars down. In the original papers this took 6-10 sessions using a needle. This still can be effective, but its OUTDATED. Since then other methods have evolved including-



The use of other size needles
The use of NOKOR or cutting needles
The use of cannula techniques


Of all these techniques, cannula stands out. The most recent paper this year shows that it has the best rate of scar breakdown with much less side effects than with NOKOR. Namely less bruising and ‘lumps’ from bleeding. 



The results of subcision is extremely variable and will depend on the technique and experience of your Plastics or Dermatologist. Ensure they can perform all techniques competently. This is especially important with dermal fillers (or fat transfer). If one subcises a depressed scar and find it has NOT got significant tethering, a filler is needed. In this situation filler or fat is needed to elevate the scar. Subcision is my preferred method for scar revision, as I can feel how many scars I am breaking with my 3 level cannula technique. This is now considered the Gold Standard in subcsion as reviewed by peer papers. All other modalities including lasers, energy devices and peels are considered ‘instruments’ in the way I practice acne scar revision. Remember treat the scar type with a method, and you will achieve the desired outcomes. Subcsion releases and remodels acne scarring from underneath. Needless to say this just a method, the results you will achieve is 90% dependent on the skill sets of your Plastic surgeon or Dermatologist.
