As we age, several things happen simultaneously in our skin. Antioxidant defenses in the skin decline, the composition of our sebum changes, and our cumulative UV exposure and environmental stress increase oxidative damage in the skin. As these things are weakening the skin, 2-nonenal has an opportunity to make its presence known.

Unlike sight or sound, smell has a direct pathway to the amygdala and hippocampus-the regions involved in emotion and autobiographical memory. Because of this connection, memories triggered by scent are often more vivid and emotionally intense than those triggered by sight.

I first became aware of fragrance layering while traveling in the Middle East, where it is deeply rooted in perfume culture, and after talking with people and friends from the region who shared their knowledge with me. After launching the brand, many customers started to ask me how to layer Maison Crivelli perfumes altogether, and I started to look at the different combinations which could work well.

Being an incense obsessive myself, it's important to note that while there's a loose parallel with the sticks you light at home, incense colognes are far more malleable and dimensional. On the skin, incense becomes an atmosphere built from resins and woods that shifts and evolves with your chemistry as it diffuses throughout the day.

One scientist at MIT, Cyrus Clarke, is working to do just that. Alongside a team of fellow researchers, Clarke has developed a physical machine called the Anemoia Device, which uses a generative AI model to analyze an archival photograph, describe it in a short sentence, and, following the user's own inputs, convert that description into a unique fragrance. The word "anemoia" was coined by author John Koenig and included in his 2021 book, The Dictionary of Obscure Sorrows.

At a time when memories are increasingly flattened into folders, feeds, and cloud backups, a new experimental device from MIT Media Lab proposes a far more intimate archive: scent. Developed by Cyrus Clarke, the Anemoia Device is a speculative yet functional prototype that translates photographs into bespoke fragrances using generative AI, inviting users not to view memories, but to inhabit them through the body.

AqueLyst approaches this challenge through odor elimination science, focusing on neutralizing odor-causing compounds at their origin. Rather than masking unwanted smells, the brand applies a science‑forward method that addresses odors at the molecular level. This approach reflects a shift away from traditional deodorizing practices and harsh chemical treatments, offering a responsible alternative for environments that require consistent, source-based odor control supported by practical chemistry and surface-safe formulations.

Remember that moment at the dog park when you see two golden retrievers, with one bouncing around with bright eyes and a glossy coat, and the other just going through the motions with a dull expression despite being perfectly groomed? Both dogs are clearly loved and cared for, but something deeper separates them: It's the difference between a dog that's genuinely flourishing and one that's simply being maintained.
