The word 'tightening' gets applied to three completely different mechanisms of action, and most clinics pick one and pretend the others do not exist. They do.
Radiofrequency, delivered at the studio via BTL Exilis, heats the deeper dermis to trigger collagen remodelling over a 60 to 90 day window. It is well suited to mild-to-moderate laxity of the jawline and neck and stacks well with injectable work.
Ultrasound-based tightening reaches deeper tissue planes and suits patients with structural descent rather than surface-level crepiness. Polynucleotides, by contrast, work at the cellular level to restore skin quality and bounce rather than produce mechanical tightening.
The right answer is rarely one modality, it is a sequenced plan across two or three, delivered in an order that respects the healing biology of each layer.
