Facial rejuvenation is familiar, but why have hands been neglected?
When people in dermatology and plastic surgery talk about anti-aging, they usually think of the face first. However, The back of the hand is the part where age is revealed first and most honestly. It is one of the signs of hand aging. The overlapping of subcutaneous fat loss, thinning of the skin, and photodamage, which makes tendons and veins appear prominent, is a typical sign of hand aging.
subcutaneous fat loss
The volume of the back of the hand is reduced, revealing the outlines of the bones and tendons.
Skin thinning
Veins and tendons appear prominent due to reduced dermal thickness
Photodamage
Accompanied by pigmentation and roughness due to accumulated UV exposure
Autologous Fat Transfer (AFT) is Additional effects of regenerative ingredients within fat, along with continuous volume enhancementWith expectations reaching up to this point, it has emerged as a strong option for hand rejuvenation. This study systematically synthesized previously scattered individual studies to summarize "how effective and safe hand fat grafting actually is."
Hand fat grafting has not received as much attention as facial fat grafting. What kind of picture would emerge if we gathered all the research accumulated over the years? A research team in Saudi Arabia systematically synthesized data from 303 individuals across 11 studies published between 2001 and 2019.
Research Design — Systematic Synthesis Based on PRISMA Criteria
Overall Results — High Satisfaction, Low Complication Rate
Key Results
Based on a synthesis of 11 studies, hand autologous fat grafting Consistently high patient satisfaction and low complication ratesThe research team showed that the adipose-derived stem cells (ADSCs) in adipose tissue provide Promotes collagen and elastin synthesis, and has anti-inflammatory microcirculation regulating effectsHe explained that this likely acted as a key factor in these good results.
1
Patient satisfaction was consistently high throughout the study.
Across the 11 included studies, Patient satisfaction with hand fat grafting is consistently reported to be high.That's it. Another characteristic is the high proportion of female patients.
2
The complication rate was assessed to be low.
at large Serious complications are rarely reported.It has been confirmed that the procedure itself has a favorable safety profile. It is evaluated as a relatively safe alternative, even when compared to temporary procedures such as fillers.
3
Long-term engraftment and regeneration effects were identified as key success factors.
The research team identified the success factors of fat grafting for back of the hand as Long-term engraftment rate of adipose-derived stem cells (ADSCs), promotion of collagen and elastin synthesis, and anti-inflammatory microcirculation regulation I cited the effect. This means there is a playback effect that goes beyond simple volume filling.
What adipose stem cells do on the back of the hand
Skin aging on the back of the hand involves the simultaneous thinning of the dermis and loss of subcutaneous fat. The adipose stem cells included in fat grafting are Improving the quality of the organization itself, apart from filling the volumeIt is involved in doing.
Collagen and elastin synthesis
It promotes the synthesis of structural proteins in the thinned dermis layer, contributing to the improvement of skin thickness.
Improvement of microcirculation
Regulates blood flow and microcirculation environment on the back of the hand through anti-inflammatory action
Long-term engraftment support
Expect a longer-lasting volume effect compared to fillers by increasing the fat engraftment rate.
Relaxation of tendon and vein contours
Alleviating the visual prominence of prominent tendons and veins through subcutaneous volume reinforcement
Limitations of this paper — what the research team candidly revealed
The individual studies included in this systematic review are Relatively old studies published between 2001 and 2019And because it includes not only randomized clinical trials but also case reports and case groups, the level of evidence is not uniform. The research team Modern research utilizing objective 3D volume measurement tools is still lacking.Pointing this out, they stated that future research equipped with such quantitative evaluation tools is necessary.
What this study says — hands are also becoming a "formal treatment target."
The significance of this systematic literature review is The fact that nearly 20 years of scattered research on hand fat grafting has been gathered and organized in one place for the first timeAs a result, it has been confirmed that hand fat grafting has already established itself as a safe and effective procedure with substantial evidence.
In the conclusion, the research team Cell-enhanced fat grafting is establishing itself as an attractive alternative to temporary fillers.While giving it a high evaluation, it was emphasized that modern research equipped with more objective quantitative evaluation tools must follow in the future.
The conclusion reached by the paper
Autologous fat grafting for hand rejuvenation Consistently high patient satisfaction and low complication rates when combining data from 11 studies and 303 patientsshowed.
The research team assessed that the regenerative effect of adipose stem cells is the key to these results, Cell-enhanced fat grafting is an attractive alternative to fillers.They concluded that... However, they stated that further modern research utilizing objective volume measurement tools is needed.
Stories from SC301 Clinic
Hand aging does not receive as much attention as facial aging, but in reality, it is one of the first areas to reveal one's age. This systematic review demonstrates that dorsal hand fat grafting is an evidence-based procedure that has already accumulated significant data.
SC301 Clinic examines even the blind spots of anti-aging information that tend to focus on the face, Providing evidence-based information regardless of body partI will continue.
Frequently Asked Questions
Facial rejuvenation is familiar, but why have hands been neglected?
When people in dermatology and plastic surgery talk about anti-aging, they usually think of the face first. However, the back of the hands is one of the areas where one's age is revealed most clearly and honestly. Prominent signs of hand aging include the overlapping of subcutaneous fat loss, skin thinning, and sun damage, which make tendons and veins stand out. Subcutaneous fat loss
