Yogurt, whether it is Greek or some other style, has unique and necessary health benefits for your diet. But when it comes to putting it on your skin, there's minimal research showing it can be of much help. Still, research on the friendly bacteria present in yogurt and how it might improve some skin conditions continues.
For now, you're far better off eating yogurt then searching for it in your skincare products. Plus, given skin's complexity as the body's largest organ, one showcased ingredient is never enough to deal with the multitude of needs skin has. Luckily this product relies on more than just yogurt to help skin.
Greek Yoghurt Advanced Nourishing Sleeping Facial is a decent formula in terms of the antioxidants and repairing ingredients it contains. However, it has some concerns that should give you pause before you go to sleep with this on your face.
The two drawbacks are the amount of alcohol in the formula (it is the fifth ingredient—not terrible but not good, either) and the amount of fragrance ingredients it contains. Seeing all these problematic ingredients in one product isn't the best news for your skin.
This moisturizer also comes packaged in a jar which puts the stability of the plant oils and yogurt at risk after the container is opened and those delicate ingredients are exposed to air (see More Info for details on why jar packaging is not ideal for skincare products).
Irritation from High Amounts of Fragrance: Daily use of products that contain a high amount of fragrance, whether the fragrant ingredients are synthetic or natural, causes chronic irritation that can damage healthy collagen production, lead to or worsen dryness, and impair your skin's ability to heal. Fragrance-free is the best way for all skin types to go for all skin types (Food and Chemical Toxicology, 2008 & American Journal of Clinical Dermatology, 2003).
The sneaky part about irritation is that research has demonstrated that you don't always need to see it or feel it for your skin to suffer damage, and that damage may remain hidden for a long time (Skin Pharmacology and Physiology, 2008).
In fact, the effect of inflammation in the skin is cumulative, and repeated exposure to irritants contributes to a weakened skin barrier, slower healing (including of red marks from breakouts), and a dull, uneven complexion (Aging, 2012 & Chemical Immunology and Allergy, 2012).
Jar Packaging: The fact that it's packaged in a jar means the beneficial ingredients won't remain stable once it is opened. All plant extracts, almost all vitamins, antioxidants, and other state-of-the-art ingredients break down in the presence of air. Therefore, once a jar is opened and lets the air in, these important ingredients begin to deteriorate. Jars also are unsanitary because you're dipping your fingers into them with each use, adding bacteria that further deteriorate the beneficial ingredients.
The vast majority of ingredients that are most beneficial for your skin are not stable in the presence of light and air, which is exactly what happens when you take the lid off a jar (Pharmacology Review, 2013 & Journal of Biophotonics, 2010).
One of the critical factors in any anti-aging or skin-healing formula is the amount and variety of antioxidants, cell-communicating ingredients, and skin-repairing ingredients, and the more the better. These function in a variety of ways to reduce the effects of the constant environmental stresses your skin experiences (Dermatology Research and Practice, 2012 & The Journal of Pathology, 2007).
Once you open that jar you bought, you immediately compromise the stability of the anti-aging superstars it contains. (You can visualize their benefits disappearing like puffs of air each time you open up that lid!)
A centuries-old Greek remedy for skin soothing, Yoghurt provides a natural source of proteins, minerals, and vitamins to nourish stressed, dry skin. This overnight facial-in-a-jar contains a Greek Yoghurt concentrate with two and a half times more protein than regular yogurt. It moisturizes skin while you sleep so you will wake up to noticeably softer, refreshed skin.
Korres is a Greek cosmetics line that was started by Athens-based pharmacist George Korres and his chemist wife, Lena. From its humble beginnings with a natural cough syrup steeped in Greek tradition to a long series of herbal remedies using local ingredients, Korres eventually morphed into a line of skincare infused with natural ingredients, a strong pull for many cosmetic consumers.
A key difference for Korres is that many of the natural ingredients they use are chosen based on the principles of homeopathy, a form of alternative medicine involving the administration of various diluted herbal tinctures to improve diseases. Unfortunately, there’s very little research-based support for homeopathy as it relates to great skincare.
Overall the Korres products are a fairly even mix of pros and cons. Many of their products are tricky for us to recommend, due to the frequent presence of fragrance (a problem for skin, whether it is natural or synthetically derived) and usage of jar packaging for several of their moisturizers.
