Burns if leaches into eyes.
Size: 0.5 Fl Oz (Pack of 1)
Do not get this product in your eyes! It really burns. Sometimes it will leach into eye and then the pain begins. I have used other eye rollers without any discomfort if accidentally goes into eyes . Please be careful. I will never order this again.

Reduces Eye Bags, for men and women
Size: 0.5 Fl Oz (Pack of 1)
I've tried a bunch of gels, creams and extracts to help reduce the eye bags which grew larger as I aged. Now at 70 years, I thought maybe my skin wasn't able to improve any more. After seeing a caffeine based cream to reduce fat on other area of the body, I would apply coffee grounds powder under my eyes and thought I did notice a difference. When I saw this roller containing caffeine I decided to try for it's ease of use. I immediately noticed a distinct difference! While the bags did not disappear altogether, they were reduced enough that I didn't wonder if they were smaller, I could see they were. I think this is marketed to men so the packaging is plain not girly and it's unscented. I don't care as long as it works. It also has a metal roller ball as applicator which is cold on the skin without having to refrigerate it. I researched the list of ingredients, all of which are deemed to be safe. Some may be irritating if you have sensitive skin, but they are not toxic if applied topically ( but can be, if taken internally or used in high doses, so don't eat it or bathe in it and you'll be ok.) I have best results when I use it morning and night but it still makes a difference if I just use in the morning. I also blend a concealer only on the shadow part of the eye bag and it disappears even more. Very reasonably priced for a safe and effective cosmetic product in a market of hype and over-priced products. Recommended.

Refreshing and effective
The Dewyhour Eye Balm Cool Stick is a game changer for my under-eye routine! It instantly hydrates and cools, reducing puffiness and dark circles. I love how it feels refreshing on my skin and absorbs quickly. After using it regularly, I’ve noticed a reduction in fine lines too. This balm is now a staple in my skincare routine! Highly recommend for anyone looking to brighten and rejuvenate their eye area.
