This study compared the effectiveness of different thread types in improving collagen profiles in UVB-exposed aging model rats, finding that PCL threads were more effective than PDO and PLLA in enhancing dermal collagen characteristics.

This study found that Heated radish extract potently suppressed melanin production in vitro and reduced wrinkle formation and collagen degradation in vivo, suggesting its potential as a skin whitening and antiaging product.

This study found that UVA and UVB exposure increased hydroquinone and sunscreen absorption in nude mouse skin, with less absorption enhancement observed in more lipophilic sunscreens.

Bioengineered skin models aging well, useful for studying aging and testing treatments.

In this study, PDO, PLLA, and PCL thread implants in ageing rat skin did not alter MMP1 gene expression but maintained collagen levels similar to young skin without UV-B exposure, suggesting possible benefits for skin collagen but not gene expression modification.
