This image shows a proximal tubule of the kidney. These tubules are highly metabolically active, their job being to reabsorb water and other vital substances (sodium, glucose and more) back into the blood as well as to secrete waste products. They are also, generally speaking, the most susceptible parts of the kidney when it comes to injury – caused by dehydration, infection, and heart issues, among other things. Urinary ceramides – a type of lipid found in the tubule cell membranes – are early markers of such damage and, it turns out, the cause of it too. The tubule cells are jam packed with mitochondria to meet their sizeable energy requirements and a build-up of ceramides directly impairs mitochondrial morphology (shape) and function. Importantly, when mice were given a ceramide-lowering drug and subjected to kidney-damaging conditions, the animals were protected from renal injury and had near-normal looking kidneys.

It’s my dog Gummy... smiling at a butterfly. He’s a Yorkie I adopted from the SPCA two years ago. He doesn’t actually chase butterflies because he is a senior dog, but I imagine as a puppy he was playful like this. My etsy pottery shop: etsy/com/shop/skimlines
The Best Hydrating Eye Creams with Treatment Benefits
Eye creams can be a great product to include in your skincare routine. With so many different eye creams available it can be hard to pick the perfect formula, especially since many eye creams are almost the same as your regular face cream and don’t provide any additional benefits. Here we have rounded up the 5 best eye creams that combine deep hydration action with clinical, scientifically proven ingredients.

This was a fun, quick and easy PM regimen, which sometimes, is exactly what you need in life.
I really like The Body Shop’s seaweed skincare line—it does a good job of purifying my pores and calming down spots without overdrying me, which is basically the gold standard for acne-prone combination skin. I wanted to do a somewhat sea-themed regimen, so I followed the cleanser and toner with the SkinFood Jellyfish Marine Hydrogel Mask, which was super moisturizing and soothing—I left it on for nearly an hour and it was still soaking in when I finally pulled it off and patted in the rest.
I wrapped up with a nice dollop of the Mario Badescu Ceramide Eye Gel, which always feels so nice on tired eyes, and sealed it all up with the J.One Black Jelly Pack, which I’ve been meaning to try to get into my regular nighttime regimen, but I’m still figuring out how best to layer it. It definitely goes best with other gel-based products, but I’m wondering if I could layer a cream on top of it as things get cooler and drier? To be continued...
