Zerumbone blocks the activation of two proteins (c-Fos and c-Jun) that tell skin cells to break down collagen when exposed to UVA light.

Zerumbone Exhibits Antiphotoaging and Dermatoprotective Properties in Ultraviolet A-Irradiated Human Skin Fibroblast Cells via the Activation of Nrf2/ARE Defensive Pathway

Cross-Sectional Study

In Vitro

The study found that zerumbone, at the same doses mentioned in the claim, blocks harmful proteins (c-Fos and c-Jun) from moving into the cell nucleus after UV exposure, which stops a process that breaks down skin collagen—exactly what the claim says.

Similar Assertions

Zerumbone stops skin cells from making too much of an enzyme that breaks down collagen, helping keep skin structure intact after UVA exposure.

80%

Zerumbone helps skin cells in a dish clean up harmful molecules (ROS) that are made when they’re exposed to UVA light—more zerumbone means less damage.

79%

A natural compound called zerumbone, when applied to skin cells in a lab, helps them survive better after being exposed to UVA light—especially at higher doses.

76%

Zerumbone slightly increases harmful molecules (ROS) in skin cells before UVA hits—this small rise is actually needed to activate the cell’s defense system.

73%

Zerumbone helps a master switch (Nrf2) move into the nucleus of skin cells, turning on protective genes—this happens within 30 minutes to 4 hours.
