The new hero in cosmetics that is useful for all skin types? Bakuchiol, which is gaining fame as an alternative to retinol, equally effective but without the same important side effects (Wang et al, Skinmed, 2019). Retinol, in fact, is a retinoid or derivative of vitamin A, and if on the one hand it helps to rejuvenate the skin leaving it smoother and more toned, on the other it can cause, especially in sensitive skin, erythema, itching and burning (Mukherjee et al, Clin Interv Aging., 2006). Bakuchiol is a natural substance, belonging to the monoterpenes family, extracted from the seeds of the Psoralea corylifolia plant. Bakuchiol has shown an antioxidant, anti-acne, anti-inflammatory and antiproliferative action similar to that of retinol, since it activates the same biological processes, and is suitable for all skin types, from young acne-prone to mature wrinkled skin. The difference, compared to retinol, is that the application of bakuchiol is much better tolerated (R K Chaudhuri et al, Int J Cosmet Sci, 2014 - Dhaliwal et al, BJD, 2018). But let's explore the uses and properties of bakuchiol.
Bakuchiol and acne
The application of creams containing 0.5% bakuchiol has been shown, in three months, to reduce acne lesions and also post inflammatory hyperpigmentation. The cream was well tolerated with no side effects (Brownell et al, J Drugs Dermatol, 2021).
Bakuchiol and skin aging processes
Creams and serums containing bakuchiol are able to regulate genes and proteins involved in aging processes. This substance has been shown to reduce expression lines, wrinkles and hyperpigmentation, while improving skin tone and elasticity. Bakuchiol has also been shown to be useful in combating photoaging and inflammation caused by sunlight (Bacqueville et al, Clin Cosmet Investig Dermatol., 2020).
Bakuchiol, where to find it
You can easily find creams and serum oils containing bakuchiol. Alternatively, you can buy Bakuchi oil, which is the oil extracted from the seeds of the Psoralea corylifolia plant which contains bakuchiol among its active ingredients. The oil should always be used diluted in other oils, such as jojoba, following the manufacturer's instructions. In general, it is recommended not to overdo the peelings if you are following a treatment with bakuchiol in order not to interfere with the action of this substance.
