Bakuchiol concept
Bakuchiol is one of the most highly regarded ingredients in the field of anti-aging skincare in recent years, and is known as "plant retinol". It is extracted from the seeds of the psoralum plant and maintains the anti-aging effects similar to retinol while avoiding the irritation and photosensitivity issues associated with traditional retinol. The following discusses the full industry picture of this ingredient from four dimensions: scientific mechanism, clinical evidence, market landscape, and compliance process.
Component Positioning
From Traditional Herbal Medicine to "Plant Retinol"
bakuchiol is a natural phenolic compound derived from the seeds of the psoralum plant (Psoralea corylifolia). It has a long history of use in traditional Indian Ayurvedic and Chinese medicine. Its molecular formula is C₁₈H₂₄O, and it belongs to the isoprenylated phenolic terpenoids. It accounts for over 60% of the psoralum volatile oil.
Although its chemical structure is completely different from vitamin A derivatives, gene expression profiling shows that bakuchiol can regulate the gene network highly overlapping with retinol, including upregulating type I collagen synthesis, regulating extracellular matrix remodeling, and promoting epidermal differentiation. This "functionally similar, structurally unrelated" characteristic enables it to simulate the anti-aging effects of retinol while avoiding the side effects caused by the receptor pathways of classic retinol.
Clinical Evidence
Comparable to Retinol, with Significant Tolerance Advantages
The most compelling clinical endorsement of bakuchiol comes from a randomized controlled study published in the British Journal of Dermatology in 2019. This study conducted a 12-week comparative test on 44 volunteers, using 0.5% bakuchiol cream (twice daily) and 0.5% retinol cream (once daily).
The results showed that there was no statistically significant difference in terms of wrinkle surface area reduction and pigmentation improvement between the two groups; however, in terms of safety, the frequency of peeling and skin irritation reported by retinol users was significantly higher, while 59% of the participants in the bakuchiol group experienced improvement in hyperpigmentation, which was better than 44% of the retinol group.
This finding established the industry position of psoralen phenol: it is not a "reduced-effect mild version of retinol", but a truly comparable alternative option in anti-aging efficacy, especially suitable for sensitive skin, damaged barrier populations, and consumers who are intolerant to retinol.
Market Landscape
SKU Explosive Growth, Formula Strategy Shift to "Systemic Synergy"
From market data, bakuchiol has moved beyond the "novel trial" stage and entered the period of scale expansion. According to the SKU-level tracking data from Euromonitor International, the number of SKUs of beauty and personal care products containing bakuchiol increased by 301% from 2021 to 2025.
It is notable that the application pattern of bakuchiol is undergoing a structural change. Early products mostly marketed it as a "single hero ingredient", emphasizing the differentiated positioning of "mild alternative to retinol".
For example, Avene's Cleanance Comedomed Intensive Serum incorporates bakuchiol as an auxiliary active ingredient and integrates it into a broader acne treatment system, exerting the function of promoting skin renewal while maintaining a barrier-friendly environment. Since its launch, this product has rapidly expanded to multiple European markets, covering pharmacies, e-commerce, and professional beauty channels. Avene has thus become the brand with the largest number of SKUs containing bakuchiol globally, accounting for 4.4% of the total.
This transformation implies that the competitive barrier for eugenol is shifting from "the raw material itself" to "the formulation capability". As more and more ingredients occupy the "moderate and efficient" ecological niche, how to scientifically blend eugenol with nicotinamide, peptides, plant extracts, etc., becomes the key to brand differentiation.
Industry Outlook
From the perspective of technological evolution, the research on eugenol has expanded from the early narrative of "retinol replacement" to the exploration of its multi-target systems biology activity. The latest review indicates that eugenol not only mimics some functions of retinol, but also independently activates the Nrf2-mediated cell protection pathway, regulates endogenous cannabinoid signaling, and mitochondrial regulatory complex, demonstrating the potential as a "skin system regulator".
For industry participants, the next stage of competition for eugenol will unfold around three dimensions: raw material purity and impurity control (compliance bottom line), formulation synergy and delivery technology (differentiation ability), and accumulation of clinical evidence for Asian skin (market persuasiveness). When "moderate and efficient" is no longer a scarce label, the true value of eugenol will depend on whether it can prove its irreplaceability in the system formulation.
