Overnight Magic in a Jar – Silky Hydration for Glass Skin
Color: Rice Probiotics (Barrier Jelly)
I’ve been using the Abib Rice Probiotics Overnight Mask Barrier Jelly for a couple of weeks now, and it has quickly earned a permanent spot in my skincare routine. It combines a clean, lightweight gel with deeply nourishing benefits—perfect if you're chasing that "glass skin" glow without heaviness.
Right out of the jar, the texture feels like a cross between a jelly and a balm. It glides on cool and soothing, absorbs within a minute, and leaves a glossy, hydrated finish that still feels breathable. It’s not greasy at all—just a gentle shimmer of hydration that makes your skin feel pampered, not overloaded.
Overnight, the formula truly does its work. In the mornings, I wake up to skin that looks softer, plumper, and noticeably clearer around the cheeks and chin. It helps lock in moisture so well that my skin stays balanced throughout the next day—no midday dryness or tightness, even when I use drying actives like retinol or vitamin C.
What really stands out is how bright and even my complexion looks. Fine, subtle dryness around my nose and mouth has disappeared, and my pores appear less obvious. The lightweight probiotic-rich formula feels soothing without burdening sensitive or acne-prone skin.
I also appreciate how well it layers in. I often apply it after serum or toner and then follow with SPF or a light moisturizer in the morning. My base products glide on beautifully over it—no pilling, no tacky residue, just glide and glow.
If you have dry, combination, or sensitive skin and want a glow-inducing overnight booster that isn’t heavy or pore-clogging, this gel mask is a dream. It provides the deep moisture of a sleeping mask but feels light and refreshing. A little goes a long way, and I’m already halfway through the jar—I’ll definitely be buying more.

Love it! Will repurchase
Color: Rice Probiotics (Barrier Jelly)
I bought this to help with moisturizing my skin that is somewhat sensitized. I get hormonal breakouts but with daily use of a prescription tretinoin and antibiotic cream I am able to keep them at bay. I also use a sulpher soap on work nights to cleanse thoroughly. All this has sensitized my skin. I use a thick nighttime moisturizer (C***ve Skin Renewing Night Cream) but it was still not enough for the dryness my skin was experiencing. I use this mask over my moisturizer and it soothes irritation and moisturizes my skin really well. Before I tried this mask I was using petroleum jelly over my moisturizer but this mask works better. It’s very thick but easy to spread. I’ve used it on my eyes and I’ve had no irritation. I apply it a couple hours before I go to bed and it soaks into my skin. After using it for a few weeks I think my skin is softer also. I will repurchase.

Sooo good!
Color: Rice Probiotics (Barrier Jelly)
This is AMAZING! I used this over my serums and a retinol moisturizer before bed and woke up with the most moisturized and smooth skin I’ve had in forever. It’s a thick consistency but smooths on easily. It is a bit tacky for a little bit before it dries down but absolutely worth it. I learned about this on Beautiful and Bothered and Johnny is right!!

A little goes a long way
Color: Rice Probiotics (Barrier Jelly)
I love overnight masks, especially for dull winter skin, and this is a really nice one! The texture is extremely thick and jelly like and it has a lovely cooling effect. It didn’t clog my pores or irritate my skin, though I do find that it feels a bit heavy and stifling if applied very liberally. But, after a few tried I’ve finally found the right amount, a little goes a very long way. Because of that, this little pot should last me a long time, even with regular use so it’s a great value! I like to layer it over my barrier protecting/repair products or over retinols and I wake up with hydrated, bright, and fresh skin in the morning! Highly recommend.
