Bakuchiol vs. Bidens Pilosa Extract: What's the Difference?

Bakuchiol and Bidens Pilosa Extract both get marketed as "gentle retinol alternatives," which makes them sound interchangeable. They're not. Here's an honest comparison of how each actually works, so you can judge which fits what you're looking for.

What bakuchiol is

Bakuchiol is derived from the seeds of Psoralea corylifolia, a plant used in South Asian traditional practices long before it became a skincare ingredient. It's the most widely available and widely marketed retinol alternative on the market today, found in products across most major skincare brands.

Mechanistically, bakuchiol isn't understood to bind retinoic acid receptors (RAR/RXR) directly, the way retinol does. Its retinol-like effects — including some published comparisons showing improvements in fine lines and photoaging with less reported irritation than retinol — are thought to come through different gene-signalling pathways that produce some similar downstream results, rather than through the same receptor mechanism.

What Bidens Pilosa Extract is

Bidens Pilosa Extract — the active in our own serum — takes a different route. It contains phytol, which oxidises into phytanic acid, a compound that binds directly to the same RAR and RXR receptors retinol activates. It's a more recently studied ingredient in skincare than bakuchiol, with a narrower published research base so far, but a more direct mechanistic link to retinol's own target.

The key difference: pathway, not just gentleness

Both are marketed as gentler than retinol, but they get there differently. Bakuchiol appears to achieve retinol-like effects via separate signalling pathways. Bidens Pilosa Extract reaches retinol's actual receptors, just without forcing the same aggressive pace of cell turnover that causes retinol's irritation. If receptor-level similarity to retinol matters to you specifically, that's the more direct comparison; if you're mainly looking for the most extensively studied gentle option, bakuchiol has the longer track record.

Honest tradeoffs

Bakuchiol's advantage: a larger body of published research, wide availability, and a longer history of real-world use to draw on.

Bidens Pilosa Extract's advantage: a mechanism more directly comparable to retinol itself, since it engages the same receptor family rather than a separate pathway.

What neither has: retinol's decades of clinical research. Both are reasonable choices for people who want to avoid retinol's irritation, but neither should be assumed to be exactly equivalent to it — they're different tools aimed at a similar goal.

What we can actually back up
