If you’re looking for a hydroquinone-free brightening and lightening serum for hyperpigmentation, you may want to look into the Is Clinical White Lightening Serum. This product was designed to specifically target and reduce stubborn hyperpigmentation and dark spots caused either by sun damage or acne scars. Some of the key ingredients in this formula include bilberry extract, alpha arbutin, mushroom extract, norwegian kelp and sugar cane extract. Of these key active ingredients and extracts, two actually serve as natural sources of popular chemical exfoliants. Bilberry extract, for example, serves as a natural source of lactic acid, while sugar cane extract serves as a natural source of glycolic acid. These two AHAs or alpha hydroxy acids, work together to exfoliate the top layer of skin, revealing the softer, smoother and more even toned skin underneath. Over time, this consistent exfoliation helps to fade away those stubborn spots, while also working to lessen the signs of aging as well.
