Bakuchiol vs Bidens Pilosa: which plant alternative suits your skin?

One has a head-to-head trial against retinol. The other reaches retinol's own receptors. We make a product with each, so here's the honest comparison, and how to choose.

01Why compare these two?

Of all the ingredients sold as "retinol alternatives", only a few have a real scientific case. Peptides and niacinamide are excellent, but they work differently from retinol. Bakuchiol and Bidens Pilosa are the two plant ingredients with a credible link to retinol's own pathway. Neither is vitamin A, neither is limited by the new EU rules, and neither comes with retinol's adjustment period.

They're also very different in practice. Different plants, different mechanisms, different kinds of evidence, and in our range, completely different textures. If you've read our guide to retinol alternatives, this is the closer look at the two that matter most.

Because we sell both, we have no reason to push you towards one. We'd rather you pick the right one first time.

02Bakuchiol, explained

In 2014, Chaudhuri and Bojanowski compared the gene activity of skin models treated with bakuchiol and with retinol. The two produced strikingly similar patterns, including switching on genes for several types of collagen. That's why bakuchiol is described as "functionally" retinol-like: a different molecule reaching a similar result. It also has antioxidant and calming activity of its own.

03The bakuchiol evidence

Bakuchiol's big advantage is that it has been tested on faces, including against retinol itself.

That's a genuinely important result, and it's why bakuchiol became so popular. It's also worth reading carefully. It was a small study, around 20 people per group, and some dropped out before the end. It compared bakuchiol with 0.5% retinol, stronger than the 0.3% now allowed in new EU face products. And it tested one specific formula. No single trial settles a question, but this one is a real one: faces, blinding, and a retinol comparison.

05The Bidens Pilosa evidence

Bidens Pilosa's evidence is earlier, and different in kind. The key study, Dieamant et al. (2015), tested a standardised extract on human skin cells and skin fragments in the lab, with retinol and retinoic acid run alongside for comparison.

Retinol raised collagen more; the extract raised elastin more. It's encouraging, but it's cells, not faces, and most of the authors worked for the company that makes the extract. There's no published trial of Bidens Pilosa against retinol on people yet.

What we do have is testing on our finished serum. In the manufacturer's consumer-perception testing, 90% felt their skin was instantly comforted, 85% saw smoother-looking skin and 65% saw fewer visible wrinkles. Self-reported, not measured, but on the exact formula. The ingredient-by-ingredient evidence is in the research behind our serum.

Bakuchiol has the better proof on faces. Bidens Pilosa has the more retinol-like mechanism. Both are far gentler than retinol.

06Head to head

07Oil vs serum: texture decides more than you think

The ingredient is only half the product. The other half is what it's carried in, and that's often what decides whether you'll actually use it every day. Our two formulas are built for different skin and different moments.

A simple rule: if your skin drinks up oils and still feels tight, an oil suits you. If oils feel heavy, or you break out easily, a water-based serum is the safer bet. Oily and combination skin almost always prefers the serum.

08Safety, purity and allergens

Both ingredients are much gentler than retinol. "Gentle" isn't the same as "suits everyone", though, so here's what to check.

10Using both together

You don't have to choose. Because the two work by different routes and neither is vitamin A, they pair well, and the textures complement each other: a light serum by day, a nourishing oil at night. It's the approach we'd suggest for dry or mature skin that wants the most from a retinol-free routine.

Introduce them a week apart, serum first. That way, if your skin does react, you'll know which one caused it. Want a routine built around your skin type? Try our routine finder or read how to layer a routine.

11Our verdict

On evidence, bakuchiol leads. It's the only plant alternative with a randomised, blinded trial against retinol on faces, and it held its own with fewer side effects. If proof is what matters most to you, start there.

On mechanism and daily comfort, Bidens Pilosa is compelling. It reaches the same receptors as retinoic acid, and in our serum it's paired with hydrators that have strong human evidence of their own. For reactive, dehydrated or combination skin, and for anyone who wants one light product for morning and night, it's the easier one to live with.

For the most complete retinol-free routine, use both: the serum by day, the oil by night. Whichever you choose, give it twelve weeks and wear sunscreen every morning.
