This animal study found that YH0618 may alleviate doxorubicin-induced alopecia and affects proteins like keratin and Smad3, suggesting potential therapeutic targets. The researchers analyzed protein expression changes to understand YH0618's effects in treating chemotherapy-related hair loss.
October 2025 in “Journal of the Endocrine Society” This research review observed that topical hormone replacement therapy, particularly estradiol and estradiol-testosterone combinations, significantly increased Type I and III collagen synthesis in the skin of postmenopausal women, suggesting benefits against collagen loss-related skin aging effects such as reduced elasticity and increased dryness.

April 2015 in “European Journal of Pharmacology” This study found that dihydrotestosterone (DHT) may shorten the hair growth cycle through mechanisms like cell-cycle arrest and β-catenin downregulation in rat hair follicle cells.
March 2026 in “Molecules” In this laboratory study, researchers reported that Camellia sinensis seed flavonoids significantly reduced oxidative stress and inflammation in UV-irradiated skin cells by modulating key signaling pathways, highlighting its potential as a skincare ingredient for anti-inflammatory and anti-photoaging benefits.
