Bakuchiol – Forschung
Überwiegend Mechanismus / Beobachtung
12 begutachtete Studien
Was die Evidenz sagt
Überwiegend Mechanismus / Beobachtung
Die meisten Studien zu Bakuchiol sind mechanistisch oder beobachtend statt RCTs, die einen klinischen Effekt messen — betrachte die Ergebnisse als vorläufig.
Die meiste Evidenz stammt aus mittelwertigen randomisierten Studien, veröffentlicht 2014–2026 mit einer typischen Studiengröße von 57 Teilnehmenden.
Basierend auf 12 Studien · 3 RCTs · 1,502 Teilnehmende insgesamt

Collectively, these findings position bakuchiol not merely as a retinol alternative, but as a systems-level bioactive that coordinates multiple regulatory networks governing skin resilience, repair and ageing.

Bakuchiol also influences retinoid transport and metabolism, including upregulation of LRAT, suggesting enhancement of endogenous retinoid activity without direct receptor activation.
These effects extend to activation of conserved longevity-associated pathways, including FOXO3 signalling, supported by in vivo evidence from Caenorhabditis elegans models.
Clinical studies consistently demonstrate improvements in photoaging, pigmentation and overall skin quality, with superior tolerability relative to retinol.
However, current evidence is predominantly in vitro, and limitations such as poor bioavailability and lack of clinical validation underscore the need for further in vivo and translational studies before therapeutic application can be established.

These findings suggest that BAK may provide therapeutic benefit across several mechanisms central to breast cancer biology.
In this review, the inclusion criteria encompassed publications describing the action of bakuchiol, its chemical and pharmacological properties, as well as its role in the treatment of various conditions, including cancers.
However, current evidence is predominantly in vitro, and limitations such as poor bioavailability and lack of clinical validation underscore the need for further in vivo and translational studies before therapeutic application can be established.
This study is intended to reiterate about possibilities of plant extracts and purified compounds in the treatment of the prevention of bacterial biofilms-related infections.

Purified compounds such as berberine, tetrandrine, embelin, xanthorrhizol, bakuchiol, etc., exhibited promising biofilm inhibition actions against different pathogenic bacteria.
Plant extracts that contain several phytochemicals are evaluated for its biofilm's inhibition property, and have shown significant potential in biofilm formation.
Antibiofilm agents act by distinct mechanisms such as inhibiting the adherence of biofilms in a surface, preventing the biofilm formations, disrupting the matured biofilms, etc.
Social media platforms are a possible space for dermatologists to engage with their patients and ensure dissemination of accurate cosmeceutical information.
Correia E, Mandel J, Cullison SRJ. · Journal of cosmetic dermatology (2025)
Trend lines were created for each term, and yearly percent differences in relative search volume index (SVI) were calculated.
Bakuchiol was the least popular cosmeceutical.
Conclusions The results reveal growing curiosity in cosmeceuticals, with interest correlating with consumers' views on social media.
Future research is needed to establish the long-term effectiveness and safety of cosmeceuticals.

Cosmeceuticals included in the review had favorable safety profiles with few significant adverse events.
The review analyzes numerous different ingredients to provide an evidence-based approach to decision-making for consumers and physicians on the use of cosmeceuticals for antiaging.
Limitations to our review include a limited number of randomized controlled trials and a need for long-term data on each cosmeceutical's efficacy and safety.
Conclusion With its stronger efficacy compared to bakuchiol and enhanced safety profile compared to retinol, SME may be the next generation of natural alternatives to retinoids.
Boira C, Chapuis E, Lapierre L, Tiguemounine J, Scandolera A, Reynaud R. · Journal of cosmetic dermatology (2025)
Methods Skin explants from a 58-year-old donor were treated with pure retinol (0.1%), bakuchiol (0.2%), or SME (0.8%).
Results Levels of collagen III were significantly increased by SME, by 23% and 16% compared to bakuchiol and retinol respectively.
Compared to bakuchiol, SME treatment increased hyaluronic acid production by 36%.
Differences were statistically significant (P<0.05) in favor of BGM complex for inflammatory lesions as well as IGA and seborrhea intensity.
Poláková K, Fauger A, Sayag M, Jourdan E. · Clin Cosmet Investig Dermatol (2015)
Randomized controlled trial in 111 acne patients comparing adapalene 0.1% gel plus a bakuchiol/Ginkgo/mannitol (BGM) complex vs adapalene plus vehicle for 2 months
Adding the BGM complex significantly improved inflammatory lesions, IGA, and seborrhea vs vehicle (P<0.05)
Bakuchiol was tested only as part of a combination product, so its independent acne contribution cannot be isolated (a key limit)
We present evidence that bakuchiol, having no structural resemblance to retinoids, can function as a functional analogue of retinol.
Chaudhuri RK, Bojanowski K. · Int J Cosmet Sci (2014)
Comparative gene-expression profiling in a full-thickness skin model showed great similarity between retinol's and bakuchiol's effects on the gene-expression profile
Bakuchiol upregulated type I, III, and IV collagen, mirroring retinol-like activity despite no structural resemblance to retinoids
Conducted by the commercial developer of the bakuchiol ingredient (industry-linked) — foundational mechanism paper
For TCA-induced PIH sites, there was a statistically significant (p < 0.05) degree of improvement with bakuchiol treatment compared to vehicle and control.
Lyons AB, Kohli I, Nahhas AF, Braunberger TL, Mohammad TF, Nicholson CL, Nartker NT, Modi K, Matsui MS, Lim HW, Hamzavi IH. · Arch Dermatol Res (2020)
Prospective, non-randomized vehicle-controlled trial in 20 subjects (phototypes IV-VI) with a history of acne-induced post-inflammatory hyperpigmentation
Twice-daily bakuchiol significantly improved trichloroacetic-acid-induced PIH versus vehicle and control (p<0.05)
On acne-induced PIH, bakuchiol did NOT reach statistical significance (p>0.05) — a key limit on its pigmentation claim
Wrinkle area, SEw, F4 significantly reduced by 16.06%, 16.71%, 25.60%, respectively, and Dermatologist assessment significant decrease in facial wrinkles, while R2 significantly increased by 23.04% after 28 days.
Shi X, Wang Y, Zhang H, Zhang T. · Health Sci Rep (2025)
34 sensitive-skin subjects used a twice-daily serum combining supramolecular bakuchiol and Terminalia chebula extract for 28 days
Wrinkle area, depth, and firmness improved and elasticity increased, with improved barrier/sensitivity markers and no adverse events
Bakuchiol was combined with Terminalia chebula, so its independent effect cannot be separated; very short 28-day duration and industry-funded
