Why doesn't skin age?

Lately, I've been pondering this because I retrieved an aged cowhide belt from my wardrobe the other day. I purchased it years past, used it often, misplaced it for a period, and now it truly appears superior to its original state. That sparked my curiosity about why hide, particularly leather, doesn't appear to mature similarly to other substances. Textiles become worn, plastics fissure, but leather somehow just alters its essence. Is this due to its preparation, or is there something unique about organic skin itself? I wonder if others have observed this same phenomenon with coats, belts, or accoutrements they have possessed for an extended duration.

I’ve noticed this too, especially with well-made leather pieces. From my experience, skin doesn’t really “age away,” it kind of evolves. Natural leather keeps its structure, and instead of breaking down fast, it forms a patina that tells a story. I once bought a simple harness and was surprised how it softened over time without losing shape. I read a bit about craftsmanship and care when I was browsing Bleak&Sleek, and it made sense — quality tanning and real leather fibers matter a lot. Regular use, some conditioning, and not overthinking it seems to be the key. It’s almost like leather rewards you for wearing it.

Fascinating subject, truly. I'm not extensively familiar with leather itself, but I do feel we frequently anticipate everything remaining static, while certain materials are intended to transform. Timber, denim, even our own skin all exhibit signs of vitality as time progresses. Perhaps the reason leather appears distinct is because we embrace those shifts as integral to its appeal rather than defects. I have always favored articles that don't appear pristine perpetually—they feel more individual somehow. Discussions such as this are enjoyable to peruse because they encourage greater observation of common items.
