Retinol Alternatives, Honestly: Bakuchiol vs Retinol, and What Is Actually in the Bottle

Retinol is the most evidence-backed cosmetic ingredient for the look of fine lines and uneven tone. It is also the one people most often give up on: the first weeks can bring dryness, flaking and stinging, and plenty of skin never really settles into it.

That gap created a category. “Retinol alternative” now appears on hundreds of labels — but it is a marketing phrase, and what sits behind it varies enormously. This is the honest version: what the phrase means, what the evidence shows for the two ingredients you are most likely to meet, and which one to choose.

What “retinol alternative” actually means

Retinol is a form of vitamin A. Skin converts it to retinoic acid, which binds to retinoid receptors in the cell and changes which genes are switched on — more collagen production, faster turnover of surface cells. The irritation comes from the same pathway as the benefit, which is why it is hard to have one without some of the other.

A retinol alternative is any ingredient that aims at the same end result — smoother texture, softer-looking lines, more even tone — without being vitamin A. There is no regulated definition. An ingredient can earn the name from a clinical trial, from a cell-culture study, or simply from a supplier’s brochure. The label will not tell you which.

Bakuchiol: the one with a head-to-head trial

Bakuchiol is a compound found in the seeds and leaves of the plant Psoralea corylifolia. Chemically it looks nothing like a retinoid. The interest began with a 2014 gene-expression study in a laboratory skin model, which found that bakuchiol and retinol switched a strikingly similar set of genes on and off, including those for types I and IV collagen. Worth knowing: that study came from the company that supplies the ingredient.

The independent test came in 2019, from dermatologists at the University of California, Davis, published in the British Journal of Dermatology. Forty-four people were randomised to 0.5% bakuchiol cream twice daily or 0.5% retinol cream once daily for twelve weeks, with neither the participants nor the grading dermatologist knowing who had which.

• Both groups saw a significant decrease in wrinkle surface area and in hyperpigmentation.
• There was no statistical difference between bakuchiol and retinol on either measure.
• The retinol group reported more facial scaling and stinging.

The authors’ conclusion was that bakuchiol is “promising as a more tolerable alternative to retinol”. That is a fair reading, and it is also a careful one. It was one trial, of 44 people, over twelve weeks, against a moderate strength of cosmetic retinol — not against prescription tretinoin, and not over the years across which retinoids have been studied.

One good trial is a reason to take an ingredient seriously. It is not a reason to say the question is settled.

Bidens pilosa: promising in the lab, unproven in people

The other “natural retinol alternative” you will see on ingredient lists is Bidens pilosa extract, from a plant also known as black jack. It is the retinol alternative in our own Retinol Alternative Serum and Retinol Alternative Moisturiser, so we owe you a straight account of it.

The published work is a 2015 laboratory study of a standardised Bidens pilosa extract on human skin cells and skin fragments. It increased collagen, elastin and glycosaminoglycans, raised the growth factor TGF-beta-1, and modulated the same retinoid receptors (RAR and RXR) that retinol acts through — with effects the authors describe as similar to or better than retinol in those assays.

Two caveats, plainly. The study was run by the extract’s manufacturer together with a university laboratory. And it is cell and tissue work: we have not found a published randomised trial of Bidens pilosa on people’s faces. A strong mechanism is a good reason to formulate with an ingredient. It is not the same kind of evidence bakuchiol has, and we would rather you heard that from us.

Which one should you use?

• Retinol works for you and your skin is comfortable? Keep using it. Nothing here out-performs the ingredient with the deepest evidence.
• You tried retinol and stopped because of flaking or stinging? Bakuchiol is the alternative with a trial behind it. Ours is the Natural Retinol Alternative Oil Serum: bakuchiol in organic jojoba, rosehip and evening primrose oils.
• You want a lightweight daily step rather than an oil? The Retinol Alternative Serum and Moisturiser pair Bidens pilosa extract with aloe, hyaluronic acid and vitamin E. Judge them as gentle, well-built hydrating products with a promising active — not as a proven substitute for retinol.
• Your main concern is firmness rather than tone? Look at peptides instead, or as well — we went through that evidence here.

One practical note: all three of these products are lightly fragranced with natural essential oils. If you know you react to fragrance, patch-test on the inner arm for a couple of days first, and see the fragrance-free options in sensitive skin and barrier care.

How to use a retinol alternative

1. Cleanse gently. Skin that feels tight after washing will tolerate every active less well.
2. Serum on slightly damp skin — a few drops of the Retinol Alternative Serum, morning and/or evening.
3. Moisturise. The Retinol Alternative Moisturiser if you want the same active in the cream step, or your usual moisturiser.
4. Oil last, in the evening. Two or three drops of the bakuchiol oil serum pressed over moisturiser. Oils seal; nothing water-based gets through them, so they always go on top.
5. SPF every morning. Not because these ingredients are known to make skin sun-sensitive, but because sun is what causes most of what you are trying to soften.

What not to combine

• Do not start it in the same week as an exfoliating acid. If your skin reacts, you will not know to which. Introduce one new active at a time, two weeks apart.
• Do not double up with retinol “for extra effect”. The point of an alternative is to avoid the irritation. Alternate nights if you want both.
• Do not judge it at three weeks. The bakuchiol trial photographed skin at 4, 8 and 12 weeks; give it the full twelve.

A realistic timeline

• Weeks 1–2: Skin feels softer and more comfortable. That is the oils, aloe and hyaluronic acid — real, but not the active at work yet.
• Weeks 4–8: Texture may start to look smoother and tone a little more even.
• Week 12: The end point of the published trial. If you see nothing by now, this ingredient is probably not the one for your skin.
• Beyond: Maintenance. As with retinol, the benefit lasts as long as the habit does.

Where to start

If retinol has defeated your skin before, start with the ingredient that has the trial: the bakuchiol-based Natural Retinol Alternative Oil Serum, a few drops every evening for twelve weeks. If you would rather have a light serum you can use morning and night, the Retinol Alternative Serum is the gentler everyday step. Add a tinted SPF50 stick in the morning, or browse everything for anti-aging.

A retinol alternative is not retinol with the downsides deleted — no ingredient gets that deal. It is a gentler route to some of the same results, with less evidence behind it and a much better chance that you will still be using it in three months. For a lot of skin, that trade is the right one.
