Radiofrequency microneedling's effects on facelifts are still unclear. Research suggests it may alter tissue planes, leading to complications like scarring and adhesions. More study is needed to understand its long-term impact.
SkinCareRadar tracks newly published skincare and dermatology research, then explains what the findings mean in plain language — with evidence labels, source links, and no hype.

PDLLA Injections May Cause Severe Granulomas in Lower Eyelid
Researchers studied a rare case of severe granulomas in a woman's lower eyelid after receiving PDLLA injections for infraorbital rejuvenation. The granulomas caused functional and aesthetic impairment, and conservative treatments failed. Surgical excision was required to manage the condition.
Why it matters: This case highlights the potential risks of PDLLA injections in the thin, anatomically complex lower eyelid region.
This case study involved a single patient, and the findings may not be representative of all individuals who receive PDLLA injections.

Radiofrequency Microneedling's Impact on Surgical Facelifts Studied
Researchers studied how radiofrequency microneedling (RFMN) affects surgical facelifts. They found that RFMN may alter tissue planes and lead to complications like dermal scarring and tissue adhesions. However, the long-term effects of RFMN on facelifts are still uncertain.
Why it matters: Understanding RFMN's impact on surgical facelifts can help patients and healthcare providers make informed decisions about facial rejuvenation treatments.
This systematic review included 21 articles, but the long-term impact of RFMN on surgical facelifts remains uncertain. Further research is needed to determine optimal timing and treatment strategies.

Postbiotic May Help Support Balanced Skin Microbiome
Researchers studied a postbiotic called PS-B1, made from fermented soy milk, to see how it affects beneficial skin bacteria. They found that a preservative-free version of PS-B1 may help some beneficial bacteria grow in lab experiments. However, more research is needed to confirm these findings.
Why it matters: Understanding how to support a balanced skin microbiome may be important for maintaining healthy skin.
This study was conducted in lab experiments and only looked at the effects of PS-B1 on a small number of skin bacteria strains. Further research is needed to confirm these findings and see if they apply to real-world skin health.

New Tool May Help Diagnose and Treat Keloid Scars
Researchers engineered a new tool to visualize and measure hypochlorous acid in keloid scars. This tool, called DQFCl-HOCl, can detect changes in keloid scars and may help evaluate the effectiveness of treatments. In lab experiments and animal studies, DQFCl-HOCl showed promise in distinguishing keloid tissue and tracking the effects of certain medications.
Why it matters: Understanding how to diagnose and treat keloid scars may lead to improved skincare treatments and better management of this condition.
This study was conducted in lab experiments and animal models, and its findings may not directly translate to human skincare. Further research is needed to confirm the effectiveness of DQFCl-HOCl in humans.

Epigenetic Skin Aging May Be Reversed with a New Serum
Researchers studied how epigenetic changes affect skin aging across different ethnicities and skin types. They found that a serum containing dihydromyricetin may help reduce epigenetic skin aging, which is associated with improved skin appearance. However, more research is needed to confirm these findings.
Why it matters: This study may help us better understand how to improve skin longevity and appearance across different skin types and ethnicities.
The study involved a small number of participants (60) and a short duration (8 weeks). Further research is needed to confirm these findings and determine long-term effects.

Red and near-infrared light may help improve scar appearance
Researchers studied whether red and near-infrared light can help improve the appearance of burn, hypertrophic, and post-surgical scars. They found that in some cases, this type of light may help reduce the appearance of scars, but more research is needed to confirm these findings. The effects of this treatment were generally well-tolerated, with some minor side effects.
Why it matters: Understanding how to improve scar appearance could be important for people who experience scarring from injuries or surgery.
Seven small studies with a total of 297 participants were included in this review, and the results suggest that red and near-infrared light may be a safe and non-invasive adjunct to standard scar management, but larger controlled trials are needed to confirm these findings and define optimal treatment parameters.
SkinCareRadar is a public research monitor focused on skincare ingredients, routines, devices, and skin conditions and concerns. It translates dermatology and cosmetic science research into plain language for the general public.
Every finding is linked to its original source. Evidence stages are labeled clearly. We do not diagnose, recommend treatment, or give medical advice. We distinguish cosmetic improvement from medically significant outcomes.
