Allure: Star Light Spot Corrector with freeze-dried mulberry root maintains higher potency.1
There's also the possibility that freeze-dried botanicals will maintain their higher potency in traditional water- or oil-based skin care. "Freeze-drying is meant to decrease the molecular weight of an ingredient, so it’s been proposed that this can help with increased [skin] penetration," says Dhaval G. Bhanusali, MD, a dermatologist in New York. Humanrace's Rice Powder Cleanser has freeze-dried snow mushroom extract, a powerhouse moisturizer. And Acaderma uses freeze-dried mulberry root in its Star Light Spot Corrector. The plant extract has mulberroside F, an organic compound that inhibits the increased melanin production that can cause hyperpigmentation. Says Anar Mikailov, MD, a dermatologist in Burlington, Massachusetts, "I’d be excited to see how freeze-dried mulberry root helps melasma."
