Hi
@EmmaDr it is the other way around. Smas FLs do NOT cut the facial retaining ligaments. Deep plane FLs CUT the facial retaining ligaments. Once deswelled the DP FL may sag with deep nasolabial folds as the facial retaining ligaments may be damaged.
My theory is that plastic surgeons may upsell the deep plane FL and charge double or triple that of smas as they sell it as longer lasting. They may then post afters with filters, photoshop editing, lighting, not let the public know these ladies went back to dermal fillers when they show a 1 year result, post early results before the deswelling, etc. But the creator of the deep plane Hamza then switched back to smas FLs.
I have seen countless dreadful facial sagging with deep nasolabials in actual patient videos (so not able to photoshop or edit) months after deep plane (I'll DM you). The surgeons may then use excuses like FLs do not address nasolabial lines or that aging continues so you need to use dermal fillers. Revision DP costs become astronomical and most surgeons may refuse to revise their DP FLs for free or at all. Not to mention it may be impossible to find a surgeon who will touch a revision DP case done by someone else as the scar tissue may be too close to the branches of the facial nerve and if the facial nerve is cut, it becomes a multimillion dollar lawsuit.
Smas FLs are better looking, cheaper, safer and nowhere near the facial nerve. I would NEVER get a DP.
