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.

Tranexamic Acid Serum May Help Improve Hyperpigmentation
A small study looked at using a topical tranexamic acid serum in patients with hyperpigmentation. The serum contains three active ingredients that aim to fight triggers of hyperpigmentation. Researchers found that applying the serum after certain in-office procedures may help improve skin appearance.
Why it matters: This study may help dermatologists and patients develop effective skincare plans for hyperpigmentation.
This study is a case series, meaning it's based on real-world experiences from eight expert dermatologists, but it's not a controlled trial. The sample size is small, and more research is needed to confirm these findings.

Setmelanotide May Help Young Children with Rare Obesity Disorder
A small study suggests that setmelanotide, a medication for rare obesity disorders, may help reduce hyperphagia and improve motor skills in a 2-year-old child with leptin receptor deficiency. The child's body mass index (BMI) and food cravings also decreased after treatment. However, more research is needed to confirm these findings.
Why it matters: This study may provide insights into the treatment of rare obesity disorders, but its relevance to skincare is unclear.
This case report is based on a single patient, and the long-term effects of setmelanotide in young children are unknown. The study had a short duration of 23 months and involved a small sample size.

Topical NAD Skinbooster May Help Reduce Melasma
Researchers studied a new treatment for melasma, a skin condition causing dark patches, using a topical NAD booster applied after microneedling sessions. A small study found that this treatment reduced the severity of melasma in 36 Korean women over 21 weeks. The treatment was well-tolerated, but more research is needed to confirm its effectiveness.
Why it matters: This study may contribute to the development of new treatments for melasma, a common skin condition affecting many people.
This study was a small case series with a limited sample size and short duration. Further research is needed to confirm its findings and establish the treatment's long-term safety and efficacy.

Customized Skincare Formulations May Help Address Dermatological Issues
Researchers studied 10 customized skincare formulations, known as magistral galenic preparations, to see if they could help address various dermatological conditions. These formulations were tailored to individual patients' needs and were found to offer potential benefits in treating conditions such as scabies, melasma, and hidradenitis suppurativa. The study suggests that these customized formulations may be a useful tool in dermatological care.
Why it matters: This research may help skincare professionals understand the potential benefits of customized skincare formulations in addressing complex dermatological issues.
The study focused on a small number of patients and did not include a control group for comparison. The findings may not be generalizable to the broader population.
