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.

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!

52 with Mature Skin — Hydrating, Smoothing Eye Patches That Actually Make a Visible Difference
Color: Pink (PDRN), Color: Pink (PDRN)
I’m 52, post-menopausal, with drier, more delicate skin around the eyes, and I’ve been using Abib products for years. It’s one of those brands I consistently come back to because the formulas are well-balanced and actually perform without irritating my skin. These patches fit right in with that experience.
The texture is one of the first things that stands out. They have a cushiony, jelly-like feel that holds its shape well and adheres comfortably to the skin. Once applied, they stay in place without sliding around, and there’s no stickiness or residue left behind when you remove them — which is not always the case with eye patches.
In terms of effectiveness, these go beyond just a temporary cooling effect. With consistent use, I notice my under-eye area looks smoother, more hydrated, and less tired overall. Fine lines look softened, and the skin has a more refined, even appearance. Puffiness is reduced, and the area just looks more awake and supported.
Hydration and softness are where these really shine. After using them, the skin feels noticeably softer and more comfortable, not tight or overly treated. There’s a real improvement in how the skin holds moisture, which is especially important for mature skin. That added hydration translates directly into a smoother, more polished look.
I also use these beyond just the under-eye area. I’ve been applying them to my nasolabial folds, and they work beautifully there as well. That area tends to show dryness and creasing, and these patches help soften and plump the look of the skin, making everything appear more relaxed and less etched.
The finish they leave behind has a subtle glow — not shiny or greasy, but a healthy, hydrated look that makes the skin appear fresher and more even. It’s the kind of glow that comes from improved skin condition, not just surface-level shine.
From a value standpoint, the jar contains a generous number of patches, and because they can be used in multiple areas, they feel much more worthwhile than single-use treatments. A little time with these gives visible results, which makes them a good addition to a routine.
Overall, these are very well done. They deliver on hydration, softness, and smoothing while remaining gentle and comfortable to use. If you’re dealing with dryness, fine lines, or puffiness — especially with mature skin — these are absolutely worth trying.

Great product
Color: Pink (PDRN)
These eye patches are incredibly hydrating and leave my under eye area looking plumper and refreshed after using. Adhere well without slipping and deliver an immediate cooling, refreshed effect. The formula feels gentle yet effective, and the patches are generously sized and comfortable. I purchased these during a promotional deal and felt they were an excellent value for the quality. A high-quality product that fits seamlessly into a skincare routine.

Gentle Retinal — No Irritation for Me
Color: Pink (PDRN)
I was honestly nervous to try these because they contain retinal, and the under-eye area can be sensitive. But I had zero irritation. No burning, no redness, no peeling.
They feel cooling and soothing when applied, and the hydrogel texture stays in place without sliding around.
After consistent use, my under-eye area looks smoother and more refreshed. I’ve noticed subtle improvement in fine lines and overall brightness.
If you’re curious about trying retinal in a gentle way, this is a great entry point. Just make sure to use sunscreen during the day, as you would with any vitamin A product.
