Retinol Alternatives: Bidens Pilosa vs Bakuchiol vs Retinol

A retinol alternative is an ingredient that does what retinol does for lines, texture and uneven pigment, either by acting on the same retinoid receptors in the skin or by producing the same measured result, without the peeling and redness that make retinol hard to keep using. Two plant extracts are sold on that promise. Bakuchiol has a randomized, double-blind human trial in which it matched 0.5% retinol over 12 weeks with less scaling and stinging¹. Bidens pilosa raised collagen and elastin in cultured human skin cells through the same receptors retinol uses, and has no human head-to-head trial in our source bank². This guide sets the three side by side on evidence, irritation, timing and sun.

What retinol does, and what it costs

Retinoids are the vitamin A family. Prescription retinoic acid is the reference; retinol is the over-the-counter form. In a review of retinoids for skin aging, they thicken the epidermis, raise collagen production in the dermis and reduce fine wrinkles, and the price is irritation, peeling and redness that rises with the dose and is most common in the first weeks of use³.

They work by binding to nuclear retinoid receptors inside skin cells, which reset how fast cells turn over and how much collagen is made. Retinol has to be converted in the skin to retinoic acid before it can bind, which is why it is gentler and slower than the prescription forms⁴. That conversion is also why retinol takes months to judge and why a higher percentage is not automatically a better one.

The cost is real for a lot of people. The first weeks of retinol commonly bring dryness, flaking and a flushed, tight face, and some skin never settles³. Those are the people the alternatives are for.

How a retinol alternative is defined

The phrase is used loosely on packaging, so it is worth pinning down. An ingredient earns the name in one of two ways. It acts on the retinoid receptors, the same molecular switches retinol flips, so its mechanism is the same⁴. Or it has been tested against retinol in people and produced the same outcome on lines and pigmentation with less irritation¹. The best case is both. Neither plant extract below has both yet.

What does not qualify: a humectant that plumps lines with water for a day, or an exfoliating acid that smooths the surface. Those are useful and have their own pages; they are not retinol alternatives, because they do not change what the skin makes.

Bakuchiol has the head-to-head human trial

Bakuchiol is a plant compound, from the seeds of Psoralea corylifolia, and it is not structurally a retinoid.

The trial is the reason it is on this page. In a randomized, double-blind study of 44 people over 12 weeks, 0.5% bakuchiol applied twice daily was compared with 0.5% retinol applied once daily. The two groups improved by the same amount on wrinkle area and on pigmentation, and the retinol group reported more scaling and stinging¹. That is a small trial and a single one, and the bakuchiol group used its product twice as often; it is still the only direct comparison of a plant alternative with retinol in people that we can point to.

N/FORM does not make a bakuchiol product. It is listed here because a guide called retinol alternatives that left it out would not be honest.

Bidens pilosa acts on the same receptors, in cell culture

Bidens pilosa is a common herb in the daisy family (Asteraceae). A standardized extract of it is the retinol alternative in Renewal Serum, and the Bidens pilosa page covers the plant itself.

The evidence is one laboratory study. A standardized Bidens pilosa extract raised collagen by 32.5% and elastin by 25.2% in human fibroblasts, the collagen-making cells of the dermis, and it did so by acting through the same retinoid receptors that retinol uses². Two things about that matter. The mechanism is the right one: this is a retinoid-receptor active, not a humectant with a good story. And it is cell culture, not a clinical trial: cells in a dish, not faces over 12 weeks. There is no human trial comparing Bidens pilosa with retinol in our source bank, so we cannot say it matches retinol on wrinkles in people, and we do not.

Renewal Serum carries 2% Bidens pilosa extract with murumuru seed butter, rosehip fruit oil and hyaluronic acid. It contains fragrance and the declared allergens geraniol, citronellol, linalool and citral. The supplier positions it as a retinol alternative; the evidence behind that word is the cell-culture study above, stated as cell culture.

Retinol, bakuchiol and Bidens pilosa side by side

Two honest notes on the table. The sun row is practice, not a trial finding: none of the three sources in it measured sun sensitivity, and daily sunscreen is the advice for every renewal active whatever it is. And the fact that the evidence for retinol is the deepest is not a small point. If your skin tolerates retinol, retinol is the best-evidenced choice. The alternatives are for the skin that does not.

Choosing between them

Start from your skin, not from the ingredient. If retinol has left you peeling and red past the first six weeks, or you cannot use it at all because of how reactive your face is, an alternative is the right call, and the routine for sensitive, reactive skin is the place to build around it. Note that Renewal Serum contains fragrance, so it is not the choice for skin that reacts to perfume; the fragrance-free renewal serum in the range is the niacinamide one.

If you want the alternative with a human trial behind it, that is bakuchiol. If you want the one whose mechanism has been shown to run through retinoid receptors and that is in a formula with rosehip oil and hyaluronic acid to buffer it, that is Bidens pilosa, with the caveat stated plainly above.

Whichever you pick, the timeline is the same. A cosmeceutical review makes the point that concentration and formulation decide whether an ingredient does anything at all, and that the quality of evidence varies widely across the category⁵. Judge the result at 12 weeks, the length of the bakuchiol trial, not at two. The guide on how long skincare takes to work sets out what to expect at each week, and the routine for fine lines and lost firmness puts the active in its place behind sunscreen.

Questions people ask

What is the best retinol alternative?

On evidence, bakuchiol, because it is the only one tested head-to-head against retinol in people: 44 people, 12 weeks, the same improvement in wrinkle area and pigmentation, with less scaling and stinging¹. Bidens pilosa has the right mechanism, acting through retinoid receptors and raising collagen and elastin in cultured skin cells, but no human comparison yet². If your skin tolerates retinol, retinol remains the best-evidenced option³.

Is Bidens pilosa as good as retinol?

Nobody has tested that in people. In cell culture, a standardized Bidens pilosa extract raised collagen by 32.5% and elastin by 25.2% through the same retinoid receptors retinol uses². A result in a dish is a reason to expect an effect, not proof of one on a face; the claim "as good as retinol" belongs only to bakuchiol, and only from one 12-week trial¹.

Can I use a retinol alternative while pregnant?

Retinoids are avoided in pregnancy under standard medical guidance. That is a rule about the vitamin A family, and it does not automatically transfer to a plant extract, but the absence of a rule is not evidence of safety either. Neither bakuchiol nor Bidens pilosa has been tested for use in pregnancy in any source we hold, so we do not call either of them pregnancy safe. Anyone pregnant or breastfeeding should ask their doctor about any active before using it.

Do retinol alternatives make skin sensitive to the sun?

There is no trial in our source bank that measured sun sensitivity for bakuchiol or Bidens pilosa. The practical answer is that every renewal active is used with a daily sunscreen, because sun exposure is the thing that causes the lines in the first place, and that advice does not change with the ingredient.

How long does a retinol alternative take to work?

The bakuchiol trial measured its result at 12 weeks¹. Retinoids in general are judged over months, and the first weeks are when irritation, not improvement, shows³. Expect a smoother, better-hydrated feel early, and judge lines at three months, the length of the trial.
