I've been using this product on my undereyes consecutively for over a month now, applied once or twice every day. I have really dark undereye circles and have fine lines, and this was cheap, locally-made by a reputable company, and is all-natural, so why not try it?
Oh, I was expecting it to help a little bit with the dark circles, but I should've read the product description more thoroughly- it's for wrinkle prevention and a protectant, not for easing dark circles.
Here's my Human Heart Nature Sunflower Beauty Oil fresh from the fridge, where I keep most of my skincare products.
Radiant, soft skin touched by the sun! Sunflower seed oil is packed with vitamins A, D & E to fight wrinkles and naturally protect skin from infections and irritants. Best applied to the sensitive under-eye area.
I like how it's absorbed by the skin around my eyes easily, and how it constantly keeps that area moisturized. A tiny dab is enough to cover both eye areas, and after a few minutes, I no longer see the oil on the skin, so that area doesn't end up shiny or feeling sweaty or sticky when I go out after applying this.
I use this product on my neck too, and some reviewers on the Human Heart Nature website mention using a small amount on their hair as well. I do not detect any scent to the oil nor did I develop any skin irritations from it. I haven't tried applying this on my entire face (and don't plan to).
I didn't notice if I got any new wrinkles or not, but there was definitely no change, good or bad, in my dark circles or amount/condition of existing fine lines. I'm now using this alternately and sometimes combined with Grapeseed oil. It's nice if all you need is a moisturizer for the eye area. This is way cheap at P99.75 (less than $2) for 50ml. Available at the HHN website.
