Soothing not oily
60 yr old white lady here. Got this for my kid who had irritated eyelids from eczema. After a week he felt done so handed it back to me. Ive been using for 2 months daily wondering if it would be nice. Way better than nice! Not oily at all. Very pleasant soft feeling around my eyes. That feeling lasts all day/all night, too. Something unexpected: reduced my eye bags! Not completely but significantly. Its allergy season so I rub my eyes a lot, usually. This cream is so soothing Im sure I am rubbing less. Delightfully surprised! Made in UK.

Really excellent but pump needs to be improved
This is a very nice eye cream. Really moisturizing but dries down with a nice tack so it doesn't run into my eyes. Had to take off a star because the pump is awful. It squirts out way too much product and it's wasted. If they fixed this issue, it would be absolutely perfect!

Excellent cream for my super-sensitive eyelids
I started with the ointment for a few days and liked it so much that I purchased this cream version. I think I like this even better! Dry, red, and itchy eyelids started improving almost immediately. I’ll use the ointment at night as needed, but will make this cream part of my everyday routine. A little goes a LONG way! Super impressed with the results.

Great for flare ups and daily use
I recently tried a new setting spray that was heavy on alcohol in its ingredients and it caused a bad reaction to the skin of my eyes that resembles eczema (I'm sure it was a similar type of atopic dermatitis) and the skin burned, hurt and itched. I was using zinc oxide cream which did seem to help but it was too heavy to wear during the days so I went on a hunt for a daytime use product and found this. I am so glad I found this!! This along with the zinc oxide cream helped heal the skin around my eyes in just a few days. I now continue to use this around my eyes day and night for the added benefit of moisture. Its non-greasy, feels very light but you can still feel the hydration it provides. I only need to use a small amount around my eyes but can see this lasting a really long time!! the tube does specify that it should be used within 6 months but I probably will only use a small amount during that time, even with daily use. My eyes are very happy that I found this product for sure and will happily buy another!

This is an excellent eye lid moisturizer.
This is the mist soothing eye cream I have ever used! I have been applying it several times a day since I received it and the dryness is clearing up.
