Your next facial could have a delicious twist, as scientists are exploring ways to turn potato waste into ‘skincare gold’.
Researchers say that potato shaws — the above-ground stems and leaves of the potato plant, usually discarded after harvest — contain key ingredients for cosmetics and makeup. Among them are solanesol, a compound essential for producing coenzyme Q10 (Q10), and vitamin K2.
Coenzyme Q10 is a powerful antioxidant widely used in serums and moisturisers for its role in maintaining healthy, youthful-looking skin. Vitamin K2, meanwhile, has been linked to collagen and calcium metabolism, which are vital for skin elasticity and bone health, and is normally sold in tablet form.
Currently, cosmetic companies mainly source solanesol from tobacco plants, but demand has risen exponentially in recent decades. If successful, the project led by the University of Aberdeen could see everyday moisturisers, face masks, and other skincare products enriched with ingredients derived from potatoes.
Previous research supports the potential benefits: a 2019 study found that applying potato peel extract to skin significantly increased collagen expression, the protein responsible for preventing wrinkles and sagging.
This innovative approach not only offers a new source of valuable skincare compounds but could also help reduce agricultural waste, making it a win for both beauty enthusiasts and sustainability efforts.
For those curious about natural alternatives to maintain radiant skin, the humble spud may soon be the latest must-have ingredient in the fight against ageing.
