The Science Behind It
There are few things in this world I think are worth $100+ for 0.5 ounces — maybe rare gems, a couple of collector’s items, perhaps a Chanel bag. Unfortunately for my wallet, Peter Thomas Roth Power K Eye Rescue is also one of them, particularly if you have dark undereye circles caused by excess melanin production or blood pooling (see below). A 2004 study in the Journal of Cosmetic Dermatology found that a combination of vitamin K, vitamin C, and retinol provided moderate alleviation of dark circles better than any other formulation of those tested. I’ve eliminated my dark circles from late nights studying in high school with this product, and it kept dark circles at bay during college. Definitely a must-have!
How I Use It
Note that Peter Thomas Roth Power K Eye Rescue doesn’t actually contain vitamin C or retinol, like in the above study. I cleverly get the effects of all three ingredients with a specific regimen.
Each morning after cleansing and toning, I normally apply a thinner eye cream with vitamin C, such as our FutureDerm Vitamin CE Eye Cream 10.0, then I apply the gel-like Peter Thomas Roth Power K Eye Rescue over the top.
At night, I apply a retinol eye cream, such as Vichy LiftActiv Retinol HA Eyes, then apply the Peter Thomas Roth Power K Eye Rescue over the top.
Is It For You?
Not sure if your dark circles will be helped by this power punch regimen?
To find out the source of your dark circles, do the following test, from Heidi Waldorf, M.D.: If you apply light pressure to the circle or shadow and it disappears, your problem is due to blood pooling under the eyes, so this product will not help you. (Vitamin K is a coagulant, so it may actually cause more blood pooling!) Similarly, if the shadow forms at the inside corner of your eye, where a tear would flow, it’s probably due to a deep tear trough, so this product won’t help.
If the color doesn’t disappear, however, the darkness is caused by excess pigment (time for some Peter Thomas Roth Power K Eye Rescue!).
I love Peter Thomas Roth Power K Eye Rescue, and I use it twice daily. I get skin issues from time to time from trying so many different products, but dark circles are never one of them. Definitely a fan!
