Scientifically Proven Benefits of the Real Bakuchiol
Bakuchiol's efficacy in skincare is well-documented through various scientific studies. Research published in reputable journals such as the International Journal of Cosmetic Science and the Journal of Cosmetic Dermatology highlights its multiple skin benefits:
- Anti-aging: Bakuchiol has been shown to significantly reduce the appearance of fine lines and wrinkles by stimulating collagen production. In a 12-week study it showed 20% reduction in wrinkle depth.
- Hyperpigmentation: 59% reduction in hyperpigmentation after 12 weeks for Sytenol® A Bakuchiol whereas 44% for Retinol.
- Antioxidant properties: It offers protection against oxidative stress and damage caused by UV radiation and environmental pollutants.
- Skin brightening: Bakuchiol helps in diminishing visible signs of sun damage and hyperpigmentation, promoting a more even skin tone.
- Acne treatment: Its anti-inflammatory and antibacterial properties make bakuchiol effective in managing acne without drying out the skin, as detailed in a study on its impact on acne-affected skin.
Risks of Counterfeit and Fake Bakuchiol Products
The surge in bakuchiol's popularity has unfortunately led to the rise of counterfeit and imitation products on the market. These fraudulent products often contain substandard or incorrect derivative ingredients, which not only fail to provide the desired skin benefits but can also pose risks such as skin irritation or allergic reactions.
P. corylifolia not only contains the bakuchiol molecule, but phototoxic components in the Babchi plant, psoralens and isopsoralens, which increases the potential for ultraviolet radiation related effects when these constituents are not removed. The presence of psoralens and isopsoralens will increase the photosensitivity when they are applied topically. The presence of psoralens can have unintended effects by causing psoralen-based photosensitivity.
The leaf, root, and stems of P. corylifolia contain furocoumarins. A well-known property of furocoumarins when exposed to UV rays is various levels of erythema (skin redness), pigmentation (dark spots) and skin damage.
Purified isolates of only the bakuchiol meroterpene on P. corylifolia is the only beneficial component of this plant when it comes to skincare.
