Microfocused ultrasound is an advanced, non-invasive technology that has revolutionized aesthetic treatments by providing skin firmness and rejuvenation. Unlike other techniques, microfocused ultrasound acts deeply, directly stimulating collagen production. This blog discusses how microfocused ultrasound works, detailing the neocollagenesis process and presenting scientific evidence that proves the efficacy and safety of this treatment.

How Microfocused Ultrasound Works
Microfocused ultrasound uses ultrasound waves that pass through the skin's surface without causing visible damage and penetrate deeper layers. The technology creates thermal coagulation points at depths ranging from 1.5 mm, 3.0 mm, and 4.5 mm, reaching the dermal and subdermal layers. These points cause controlled thermal damage that triggers a natural tissue repair process and the production of new collagen fibers, called neocollagenesis (Sasaki & Tevez, 2012³; Gutowski, 2016²; Dierickx, 2006³).
This mechanism is highly safe, as the ultrasound waves are focused on specific areas of the skin, preserving the superficial layers. Studies prove that the ideal temperature for collagen stimulation occurs between 60°C and 70°C. At this temperature, the collagen fibers already present undergo a denaturation process and activation of fibroblasts, the cells responsible for collagen production (Alster & Lupton, 2007⁷; Wulkan, Fabi & Green, 2016⁴).
The Science Behind Collagen Production: Neocollagenesis
Microfocused ultrasound deeply heats the skin, promoting the creation of new collagen and resulting in firmer, younger-looking skin.
Collagen production after microfocused ultrasound occurs in a process known as neocollagenesis, which is triggered by controlled thermal injury in the deeper layers of the skin. Fibroblasts, activated by heat, initiate collagen regeneration, reorganizing fibers and increasing skin density and firmness over the weeks. The formation of new fibers occurs gradually and reaches its peak between 4 and 6 months after treatment, with results that can extend up to 6 months, or one year after the treatment (Pissurno, 2022⁵; Dos Santos Vianna Néri et al., 2022¹).
The action of microfocused ultrasound is further aided by the production of heat shock proteins (HSPs). These proteins are activated by the increase in temperature and help in cellular recovery, stabilizing newly produced collagen and promoting skin structure. Studies indicate that this process can significantly increase skin firmness, especially in areas of the face and neck, where collagen loss becomes more evident with aging (Gutowski, 2016²; Dierickx, 2006⁸).
Scientifically Proven Benefits of Microfocused Ultrasound
Studies and clinical reviews demonstrate that microfocused ultrasound offers significant and lasting benefits for facial and body rejuvenation. Microfocused ultrasound not only improves skin firmness but also slows down aging.
Below are the main scientifically proven benefits:
-
Firmness and ElasticityMicrofocused ultrasound promotes a significant improvement in skin firmness, especially in areas with mild to moderate sagging. The production of collagen and elastin in the deeper layers provides a natural lifting effect (Pissurno, 2022⁵; Luccia & Gotardo, 2023⁶; Dos Santos Vianna Néri et al., 2022¹).
-
Preventive Effect against AgingSince the treatment stimulates collagen production, it can slow down the aging process by strengthening the skin's structure. Ultrasound acts as an "active prevention" against sagging and wrinkles, providing a younger and more natural appearance (Luccia & Gotardo, 2023⁶).
-
Long-lasting resultsThe effects of microfocused ultrasound are long-lasting, with results that can last up to a year and a half after a single session. The duration of the results may vary depending on the individual response and skin type, but studies show that collagen production remains active for months (Gutowski, 2016²; Sasaki & Tevez, 2012³).
-
Effectiveness in Different Areas of the BodyMicrofocused ultrasound is not limited to the face; it can be used on areas such as the neck, arms, abdomen, and thighs, providing firmness to body areas that suffer from sagging (Dos Santos Vianna Néri et al.1, 2022; Pissurno, 2022⁵).
-
Compatibility with BiostimulatorsMicrofocused ultrasound can be combined with collagen biostimulators, such as Sculptra® and poly-L-lactic acid, amplifying treatment results and providing greater density and elasticity to the skin (Lobo et al., 2023⁹; Dal Piva & Fraporti, 2024¹⁰).
What to Expect During and After Microfocused Ultrasound Treatment?
During treatment, the patient may feel a slight warming sensation and a feeling of pressure, which vary according to the depth of application and individual sensitivity. The procedure is well tolerated by most patients and does not require a recovery period. Side effects, when they occur, are mild, such as redness or temporary swelling (Sasaki & Tevez, 2012³; Alster & Lupton, 2007⁷; Dierickx, 2006⁸).
Results begin to appear from the third month and continue to improve gradually until 6 months after application. Each person responds uniquely to the treatment, influenced by factors such as age, genetics and lifestyle (Gutowski, 2016²; Dos Santos Vianna Néri et al., 2022¹).
Conclusion: Maintain Your Rejuvenation with Liftera
Microfocused ultrasound is a scientifically proven and safe option for those seeking skin rejuvenation and firming without resorting to invasive surgery. The technology acts directly on collagen production, promoting natural and long-lasting results. When combined with biostimulators, the treatment is even more effective, bringing visible benefits to the face, neck, and body areas.
Backed by numerous studies and clinical reviews, microfocused ultrasound stands out as an effective method for combating sagging skin and improving skin quality. Its safety, efficacy, and duration of results make it a solid choice for those seeking visible, scientifically-backed rejuvenation.
