What does this research mean for the field?

Adding a multi-ingredient, glutathione-containing booster to a GHK-conjugated spicule base regimen provides statistically greater short-term improvements in facial aging indicators compared to the base regimen alone. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To evaluate the clinical efficacy and safety of a GHK-conjugated spicule regimen and assess the incremental aesthetic benefits of adding a 1% glutathione-containing booster.

Implication

Active-controlled split-face trial demonstrates enhanced skin rejuvenation with a glutathione booster in adult women, indicating incremental aesthetic benefits for spicule-based peptide delivery.

Key Points

To evaluate the clinical efficacy and safety of a GHK-conjugated spicule regimen and assess the incremental aesthetic benefits of adding a 1% glutathione-containing booster.
Conducted a prospective, active-controlled split-face clinical trial (TRN: PRE20250909‐005) in 20 healthy Asian women receiving five weekly facial treatments.
Applied a GHK-conjugated spicule base regimen to one side of the face and the base regimen plus a 1% glutathione booster to the contralateral side, assessing skin parameters at baseline, after sessions 1 and 3, and 4 weeks post-treatment.
The intensive booster regimen achieved greater reductions in periorbital wrinkle depth (−0.0144 vs. −0.0084 mm), nasolabial wrinkle depth (−0.0227 vs. −0.0173 mm), and mean pore volume (−0.0007 vs. −0.0005 mm³) compared with the base regimen.
The booster regimen produced greater improvements in dermal density (+7.27 vs. +4.49) and surface roughness (−1.23 vs. −0.73 μm), with no reported adverse events.
