Bakuchiol is a plant-derived cosmetic ingredient studied mainly for visible signs of photoaging. A review found 15 human trials, but most lacked a control group or used several ingredients together. One small, 12-week trial found improvement in wrinkles and uneven pigment with both bakuchiol and retinol. It cannot establish that every bakuchiol serum works like retinol. [1, 2]

What does the clinical evidence actually show?
The attractive story is simple: bakuchiol comes from a plant, retinol can be irritating, and therefore the plant ingredient must provide the same result more gently. The evidence has more conditions attached. A 2024 systematic review identified 15 human trials of topical formulas containing bakuchiol. Twelve were open-label studies without a control group, ten tested combinations of ingredients, and four did not state the bakuchiol concentration. Different designs and outcomes prevented a useful meta-analysis. [1]
Those details matter if you are deciding whether to buy a serum. When a formula contains several active ingredients, any change in the skin cannot confidently be credited to bakuchiol alone. Without a comparison group, changes over time may also reflect other parts of the routine, seasonal differences, measurement variation or simply the passage of time. The review does not say bakuchiol has no effect; it says current evidence is too uneven for a broad promise. [1]
The retinol trial is informative, but narrow
In a randomized, double-blind comparison, 44 people used either a 0.5% bakuchiol cream twice daily or a 0.5% retinol cream once daily for 12 weeks. Both groups showed improvement in wrinkle surface area and hyperpigmentation; the study did not detect a statistically significant difference between groups. People using retinol reported more scaling and stinging. [2]
The two schedules were different, and the sample was small. “No significant difference” in that study is not proof that two ingredients are interchangeable at every strength, in every formula, or over years of use. It also is not a head-to-head comparison with every retinoid product. If you want to understand the wider family and its much longer research history, use the retinol guide. [1, 2]
What about acne, pigmentation and wrinkles?
The strongest direct comparison here concerns visible wrinkles and uneven pigment in a particular photoaging study. The systematic review also found trials involving acne and post-inflammatory pigmentation, but their mixed formulations and weak controls make ingredient-specific conclusions difficult. A serum marketed for acne should not be treated as a tested acne therapy just because bakuchiol appears on the label. [1, 2]
Uneven pigment has several causes. A mark left by a breakout, a sun-related spot and a condition such as melasma do not become the same problem because a product claims to “brighten.” The dark spots guide helps separate those questions. A clinician should assess a changing, unusual or persistent patch rather than letting a cosmetic claim stand in for diagnosis.
How could bakuchiol fit into a routine?
Start with the objective, not the ingredient’s reputation. Are you trying to make a routine easier to tolerate, or are you hoping to address a particular visible concern? The trial tested one cream twice a day for 12 weeks; it did not establish a universal daily schedule for every serum on a store shelf. The amount, vehicle and other ingredients in a finished product may differ from the research formula. [1, 2]
A practical introduction is to keep the rest of your routine steady, follow the product label and try the new formula on a small area first. If your skin tolerates it, use it consistently rather than changing several products at once. This is a way to notice whether a formula suits your skin, not a clinically validated bakuchiol dosing protocol. A mild cleanser and moisturizer can make the routine easier to interpret than a stack of actives.
Can you use it alongside retinol?
There is no result in these two sources showing that layering bakuchiol over retinol gives a better outcome than either alone. The published comparison assigned people to separate groups. If you already use retinol comfortably, adding another active without a clear reason makes it harder to know which product caused any new irritation. If you want to compare routines, change one step at a time and consider the whole formula, including fragrance and exfoliating acids. [1, 2]
The same principle applies to acids and vitamin C. Ingredient names alone cannot predict how two finished products feel when combined. A skin care routine does not need to contain every popular active. If a product repeatedly stings, stop and reassess; persistent pain or a rash deserves medical advice. Pair daytime care with sun protection, especially when your goal concerns visible sun damage.
Serum or cream: does the format decide?
The direct retinol comparison used creams. Other trials reviewed by Fanning and colleagues used assorted formulations, many with more than one active. The word “serum” gives no evidence of an effective bakuchiol dose. Read the complete ingredient list, instructions and intended use. A comfortable texture is relevant because a product you cannot tolerate is unlikely to remain part of your routine. [1, 2]
If a label states a percentage, do not treat it as a universal target. The often repeated 0.5% figure describes the specific trial, not a proven minimum or maximum for all skin types. A higher number is not automatically better, and a lower number is not automatically useless. Ask what the product is claiming, whether the formula resembles the one tested, and what level of uncertainty you are comfortable with.
Where should you be cautious?
A botanical source is not a safety certificate. The systematic review mainly assessed short human studies and found many design weaknesses. The direct comparison followed 44 people for 12 weeks. Neither source establishes long-term outcomes, uncommon adverse reactions, or safety in pregnancy and breastfeeding. If you are pregnant, planning pregnancy or nursing, discuss a new active with your clinician rather than interpreting “retinol alternative” as a pregnancy safety claim. [1, 2]
Retinol users in the trial reported more scaling and stinging, but this does not mean bakuchiol cannot irritate an individual user. Finished formulas contain carriers, preservatives and possibly fragrance. A reaction can be related to the entire product. Stop use if you develop continuing burning, swelling or a spreading rash; seek medical advice when symptoms are significant or do not settle. For day-to-day decisions, tolerance of your own product matters more than a general label.
There is also an evidence limit around “natural” and “clinically proven.” A clinical study can be real while a marketing sentence extends far beyond it. Ask four questions: Was bakuchiol used alone? Was there a control group? How many participants were studied, and for how long? Did researchers measure the concern in the advertisement? In the current review, answers varied enough that a single effect estimate could not be calculated. [1]
A useful expectation is modest: the ingredient may be worth considering if you prefer to test a different cosmetic approach to visible photoaging, but the available data do not establish equivalence to prescription retinoids or prove a particular product will change your skin. If a concern has become painful, inflamed or emotionally burdensome, a dermatologist can help identify what is happening and which options have evidence for that condition.
Frequently asked questions
Is bakuchiol the same as retinol?
No. They are different ingredients. A small trial compared specific creams and found changes in both groups over 12 weeks, with more reported scaling and stinging in the retinol group. That observation should not be stretched into a claim that all products are equivalent. [2]
Is bakuchiol safe during pregnancy?
These sources do not establish pregnancy or breastfeeding safety. “Plant-derived” does not answer the question. Ask the clinician who knows your situation before starting a new product, particularly one marketed as an alternative to another active. [1, 2]
Does bakuchiol help acne?
The review included some acne-related trials, but many tested combinations or had no control group. It does not justify treating a cosmetic bakuchiol serum as a proven acne therapy. For the condition itself, read the acne guide and consult a dermatologist if lesions are painful or leave marks. [1]
How long should I wait for a visible result?
The direct comparison lasted 12 weeks. That duration describes its observation period; it is not a deadline for every formula or person. Take notes on what you use and avoid changing multiple active products at once, so you can make a more honest assessment of your own routine. [2]
