Scientists test new non-invasive, painless facial rejuvenation technology

A research team from the University of Coimbra’s Faculty of Sciences and Technology (FCTUC), in collaboration with LaserLeap Technologies and Be.U_TheSkinCareClinic, has tested innovative aesthetic techniques that can regenerate and firm facial skin without surgery, needles or pain.

The protocols will be launched this month at Be.U beauty corners, a UC spin-off, located in Coimbra Shopping, Oeiras Parque, and Cascais Shopping.

“This technology uses ultrasonic energy delivered to deep skin layers, combined with cosmetic molecules such as growth factors and exosomes, to restore the skin’s natural repair processes, enhancing firmness, radiance and youthfulness,” says Carlos Serpa, professor in FCTUC’s Department of Chemistry and researcher at the Coimbra Chemistry Centre (CQC).

Gonçalo de Sá, also a CQC researcher, adds: “These procedures extend the effects of ultrasound well beyond traditional lifting, stimulating collagen and elastin production and improving facial skin density, luminosity and vitality without invasive treatment.”

“The results are visible from the first sessions and improve week by week, matching the preference for progressive, maintenance-focused skincare,” the scientists note.

Combining FCTUC-developed ultrasound with growth factors allows cosmetic molecules to penetrate the epidermis effectively, reversing signs of skin fatigue from prolonged sun exposure and enhancing facial protection renewal. Hyaluronic acid also shows increasingly evident epidermal revitalization through local volumization when delivered with ultrasound.

The technique, designed specifically for a non-invasive, painless procedure that does not leave marks, is patented by UC and its inventors — Luís Arnaut and Carlos Serpa, professors at FCTUC’s Department of Chemistry, and Gonçalo de Sá, CQC researcher.
