I can't put a pic of me with my eyes barely open and a big red note bigger than Rudolph's!!!!!
I tried this item because of the description given on the website, unfortunately, I had a bad reaction to one use of it and I ended up in the Emergency Room at my local hospital.....what a waste of $$$ for me, especially because it said it was all natural.....I have never had a reaction to anything I have put on my face before....I still have a big red nose and one side of my face/nostril is full.....

It feels refreshing
I applied the Dewyhour Eye Balm Cool Stick, and it instantly feels refreshing, almost like a menthol sensation. It’s very cooling and soothing on the skin. However, I recommend not applying it too close to your eyes, as the cooling effect can be a bit strong in that area. Overall, it works well to hydrate and refresh the under-eye area, and I love the silky texture it leaves behind!

Desde que lo uso, he notado una gran diferencia: mis ojos lucen más despiertos y luminosos.
Esta maravilla es perfecta para esos días en los que las ojeras parecen más pronunciadas. Su fórmula ligera y fría proporciona un alivio inmediato, dejando la piel alrededor de mis ojos fresca y revitalizada. Lo mejor de todo es que su aplicación es súper sencilla: solo desliza la barra suavemente y siente cómo se derrite en la piel, brindando una sensación de frescura instantánea. 🙌 Además, es ideal para llevar en el bolso y usar en cualquier momento del día. Desde que lo uso, he notado una gran diferencia: mis ojos lucen más despiertos y luminosos. Sin duda, es un must-have en mi rutina de belleza.

It brightens before your eyes!
You know how some products need time before you see the difference, this one doesn’t. As soon as you apply it you can visibly see how light your under eye is. The formula is very rich, not too moist it just makes my under eyes look sooo vibrant!
