Psoralea corylifolia seeds — the natural botanical source of Bakuchiol

1. Product Overview

Bakuchiol is one of the most celebrated natural active ingredients in the global cosmetics industry. World-Way’s Bakurene™ Bakuchiol is extracted from high-quality Psoralea corylifolia seeds using advanced extraction technologies, achieving a purity of over 99% (HPLC). Appearing as a pale yellow to brownish-yellow clear oily liquid, bakuchiol possesses exceptional photochemical and hydrolytic stability—a key advantage over traditional retinol, which degrades upon UV exposure. This allows bakuchiol to be safely incorporated into daytime skincare formulations. Backed by international certifications including ECOCERT, USDA Organic/EU Organic, HALAL, KOSHER, ISO9001, and FSSC 22000, Bakurene™ Bakuchiol meets the highest global quality standards.

2. Botanical / Source Profile

2.1 Botanical Information

Bakuchiol is derived from the dried ripe seeds of Psoralea corylifolia L., a plant belonging to the Fabaceae family. Also known as Bu Gu Zhi (補骨脂) in Traditional Chinese Medicine, this plant is native to China, India, Sri Lanka, and Southeast Asia. The seeds are small, kidney-shaped (3–5 mm), dark brown to blackish-brown in color, with a fine reticulated surface texture.

In Traditional Chinese Medicine, Psoralea corylifolia has been used for over a thousand years as a warming herb that supports kidney yang, strengthens bones, and improves respiratory function. Modern science has now unlocked its most valuable skincare compound—bakuchiol.

2.2 Extraction Process

Bakurene™ Bakuchiol is produced through a carefully controlled extraction process using ethanol or ethyl acetate as the extraction solvent. The process includes raw material grinding, solvent extraction, filtration and concentration, column chromatography purification, and solvent removal. Each batch is rigorously tested by HPLC to guarantee a minimum purity of 99%. The entire process is environmentally friendly and preserves the full biological activity of the natural compound.

3. Active Ingredients

Bakuchiol (CAS: 10309-37-2, molecular formula: C₁₈H₂₄O, molecular weight: 256.38 g/mol) is a meroterpene phenol compound consisting of a phenolic hydroxyl group linked to a monoterpene side chain. This unique structure endows bakuchiol with multifunctional bioactivity.

Remarkably, bakuchiol has been shown to modulate a similar gene expression profile to retinol in human skin fibroblast cultures. It upregulates collagen synthesis genes (COL1A1) while downregulating matrix metalloproteinase (MMP) expression. Unlike retinol, bakuchiol’s phenolic structure provides superior antioxidant capacity and photostability, allowing it to resist UV-induced oxidative stress without degradation.

4. Health Benefits

4.1 Anti-Aging & Photo-Protection

Bakuchiol stimulates dermal fibroblast proliferation and significantly increases type I collagen (COL I) synthesis, while downregulating matrix metalloproteinases (MMPs) to reduce collagen breakdown. In a 12-week double-blind clinical study, 0.5% bakuchiol reduced wrinkle area by approximately 20%, comparable to retinol, yet with significantly better skin tolerance. Bakuchiol also effectively protects against UVB-induced photoaging.

4.2 Skin Lightening & Pigmentation Reduction

Bakuchiol is a potent tyrosinase inhibitor, suppressing both monophenolase and diphenolase activities. At low concentrations, it outperforms the well-known whitening agent arbutin in tyrosinase inhibition. It also downregulates the expression of tyrosinase, TRP-1, and TRP-2 in melanocytes, blocking melanin synthesis at its source. In a 12-week clinical trial, the bakuchiol group showed a 59% reduction in hyperpigmentation, surpassing the retinol group’s 44%.

4.3 Oil Control & Anti-Acne

Bakuchiol reduces sebum production by downregulating 5-α-reductase expression. In antibacterial zone-of-inhibition tests, bakuchiol demonstrated significantly stronger activity against Propionibacterium acnes than salicylic acid—even at low concentrations. This dual sebum-control and antibacterial mechanism makes bakuchiol highly effective for managing mild-to-moderate acne and post-inflammatory hyperpigmentation (acne scars).

4.4 Anti-Inflammatory & Antioxidant

Bakuchiol exhibits comprehensive free-radical scavenging activity, significantly boosting superoxide dismutase (SOD) and catalase (CAT) activity in cells. It markedly reduces the levels of pro-inflammatory cytokines PGE2 (prostaglandin E2) and MIF (macrophage migration inhibitory factor), with stronger suppressive effects than retinol. This makes bakuchiol ideal for sensitive skin types seeking anti-aging benefits without irritation.

5. Applications & Market

5.1 Recommended Applications

Recommended dosage: 0.5%–2% (by weight of cosmetic formulation).

· Anti-aging serums and creams: paired with antioxidants for professional anti-aging product lines

· Brightening and spot-correction lotions: synergistic with vitamin C, niacinamide, and other whitening agents

· Acne-control gels: a gentle yet effective alternative to salicylic acid

· Eye-area anti-wrinkle treatments: gentle enough for the delicate periorbital region

· Repair masks: soothing and repairing UV-damaged skin

· AM skincare routines: safe for daytime use due to its photostability

5.2 Market Position

As the flagship "plant-based retinol," bakuchiol is rapidly capturing global cosmetic ingredient market share. Its core competitive advantages include:

· No adaptation period required: naturally gentle, suitable for sensitive skin and people of color

· No phototoxicity: safe for daytime use, unlike conventional retinol

· Multi-functional: anti-aging, whitening, anti-acne, and anti-inflammatory all in one molecule

· Clean Beauty trend alignment: meets the growing consumer demand for natural, sustainable ingredients
