The Clarisonic Sonic Radiance Brightening Activator Serum purportedly helps brighten the skin, and prevent and fade dark spots. It is also supposed to provide intense hydration for a more youthful appearance. Serums are intended to treat and nourish the skin. As opposed to cleansers that are washed away, serums remain on the skin; as such, I am more critical of their ingredients. Not to mention the fact that they are pricier.
The most impressive ingredients in this serum are tocopheryl acetate (Vitamin E), ellagic acid (an antioxidant), and lactic acid (an alphahydroxy acid and exfoliant). The key brightening ingredient appears to be phenylethyl resorcinol, a synthetic antioxidant known for its whitening properties. There are also various humectants and moisturizers, such as glycerine and butylene glycol.
Out of the skincare products Clarisonic sent to me, this is the star. I have not used it enough to attest to the effects on discoloration, but I can say that it is very moisturizing. Although I will likely need something a bit heftier in the winter months, I did not need a separate moisturizer after using this- it was very hydrating without being sticky or greasy. This mid-priced serum becomes even more attractive knowing that, unless you have very dry skin, you don’t need to spend the cash to buy a separate moisturizer!
Clarisonic Sonic Radiance Brightening Activator Serum retails for $65.00 for 0.98 oz.
