Can you please review the Korres Wild Rose + Vitamin C Advanced Brightening Sleeping Facial? I saw it new at Sephora and wanted to know if it is a good choice to lighten a dark sun spot on my face?
Though it’s hard for me to honor every reader request for a specific product review, I do my best. And the fact that Korres Wild Rose + Vitamin C Advanced Brightening Sleeping Facial ($48.00, Amazon.com) claimed to be a “sleeping facial” – well, that made me just have to put my investigative glasses on.
Turns out there’s really no difference between the Korres Wild Rose + Vitamin C Advanced Brightening Sleeping Facial and a regular anytime moisturizer, except for a large dose of fragrance. While most chemists try to keep fragrance minimal, Korres hit this one with a heavy hand, infusing it with a lot of wild rose fragrance. This is actually backed in science: In a 2007 study published in Nature, Harvard researchers found that deep, slow wave sleep (SWS) is heavily influenced by the scent of wild roses. A higher proportion of subjects were found to be in slow, deep wave sleep (SWS) when exposed to the scent than when they were not. Hence why Korres Wild Rose + Vitamin C Advanced Brightening Sleeping Facial is a “sleeping” facial.
As far as whether or not this will lighten sunspots over time, the answer is yes, due to a mix of soybean oil and four different forms of brightening vitamin C: Rosa Canina fruit oil, Rosa Rubiginosa seed oil, Rosa Canina flower extract, and ascorbyl tetraisopalmitate. Soybean extract has been found to lighten sun spots when used twice daily for two weeks in 2% concentration (Dermatology, 2000), while vitamin C has been documented to lighten and brighten skin in a multitude of skin care studies and journals, including in a comprehensive review in The International Journal of Therapeutics.
Unfortunately, studies have shown that there are agents more potent than soybean extract and/or vitamin C in fighting hyperpigmentation. For instance, there are four prescription-strength hydroquinone treatments that have documented results when used for eight weeks: Tri-Luma, (0.05% retinoid and 4% hydroquinone); Lustra (4% hydroquinone, 4% glycolic acid); Lustra-AF (4% hydroquinone, 4% glycolic acid, SPF 15); and Alustra (4% hydroquinone and retinol). Note that these agents should only be used for up to eight weeks at a time to reduce the risk of ochronosis, a darkening of the skin. (For more facts you should know about Hydroquinone, please read “5 Little Known Facts Every Hydroquinone User Needs to Know Immediately.”). On the off weeks, other agents with the same mechanism of action as hydroquinone (inhibiting the enzyme tyrosinase) can be used, such as 2-4% kojic acid.
Still, Korres Wild Rose + Vitamin C Advanced Brightening Sleeping Facial is a very skin-softening and aromatic product, with a high concentration of jojoba oil. Of all the oils out there, jojoba oil has been found to be one of the most emollient (skin-softening), as it is more emollient than either many other common cosmetic oils, including castor and mink oils (Journal of the Society of Cosmetic Chemistry, 1971). Using Korres Wild Rose + Vitamin C Advanced Brightening Sleeping Facial is likely to put you into a deep sleep if you are like 50% of subjects in the Nature study whose sleep is heavily affected by scent. It is also likely to make you wake up with softer and slightly brighter skin over time. So, overall, a lovely product.
However, to answer your question, Mary – if you want a sunspot treatment, look to prescription-strength hydroquinone, and see your dermatologist. :-)
