Lifting and boosters differ in the depth of skin they target and how they work. Lifting delivers thermal energy to the deep dermis and, beneath it, the SMAS (superficial musculoaponeurotic system) layer at a depth of about 4.5 mm, focusing on tightening sagging tissue. Boosters work in the superficial dermis (1–2 mm) to stimulate collagen production, improving the skin's own quality and elasticity.
Lifting procedures use energy-based devices such as ultrasound or radiofrequency to deliver heat stimulation to deeper layers. This heat induces collagen contraction and neocollagenesis, leading to a tightening effect over time. Booster procedures deliver ingredients or stimulation that improve collagen and moisture in the dermis through injections or micro-stimulation.
In summary, lifting can be understood as a 'structural tightening' approach, while boosters take a 'filling and fortifying the skin foundation' approach. Because their goals differ, they are often used complementarily rather than competitively.
