1) I feel like we're in the middle of a pretty fundamental reset in how beauty claims are made and more importantly, how they’re evaluated. Consumers are more interested in evidence and mechanisms. You see that in the rise of claims tied to barrier repair, microbiome balance, and inflammation. At the same time, there’s a big shift from “anti-aging” to “aging well” or longevity thinking. That’s especially evident in claims language that is increasingly about resilience and prevention rather than reversal. The exciting part for me as a cosmetic chemist are the new innovative methods and instrumentation we have available today to measure efficacy, the challenge is making sure marketing claims don’t outpace the data.

4) This is where things get really interesting and also really difficult. The nutricosmetics category has grown because it taps into the compelling idea that beauty isn’t just topical. And the “beauty-from-within” concept continues to be driven by a broader shift toward preventive health and daily wellness routines. Where things get more complicated is efficacy. When I look at it from a scientific and formulation perspective there are some real challenges, especially around clinical evidence and cost–benefit. That doesn’t mean that some of these products don’t have some benefit but it does mean that expectations need to be carefully managed because, just like topical skin care, results are subtle and take a long time to achieve. And lastly, but perhaps most importantly, claims need to be honest and well substantiated which is necessary to build long-term trust.

5) K‑beauty has had a big influence in skincare. It’s pushed the industry toward barrier-focused care and fun, sensorial textures. Korea’s fast product iteration model is also likely pushing nutricosmetics toward quicker launches and more experimental formats. But I think it’s really important to separate formulation innovation from marketing narratives. K‑beauty excels at storytelling, and sometimes those stories get ahead of science.

Take snail mucin, for example. It’s positioned as this hero ingredient but from a formulation standpoint, it’s largely functioning as a humectant system not fundamentally all that different from some other materials we already use like glycerin, hyaluronic acid, or hydrocolloids. Snail secretion filtrate does contain a mixture of polysaccharides and small molecules that can contribute to hydration. But the key question I always come back to is it meaningfully better than existing approaches and does that justify the sourcing? Because once you start asking how that ingredient is harvested and standardized, the magic starts to fade.

9) If you look at how “clean beauty” has evolved over the past decade, we’ve really moved through a few distinct phases. Early on, it was very much about “free-from” positioning and focused on what’s not in the formula. Then it shifted to ingredient transparency and safety. Consumers still care about safety and transparency, but now they’re asking more questions about sustainability. Questions like where was this raw material sourced? What’s the environmental footprint of producing it? Can the brand actually verify its sustainability claims?

One of the more interesting developments in the cosmetic ingredients space is the rise of upcycled materials. We’re seeing byproducts from agriculture and the food industry, things like fruit peels, seed oils, even spent coffee grounds reframed as functional cosmetic ingredients. The isolation and characterization of specific compounds from these materials is particularly interesting. But turning a waste stream into a reproducible ingredient is definitely not easy, it requires real research and process controls. Another big shift is the use of biotechnology. Instead of relying on plant extraction, companies are moving towards using fermentation and bio-based manufacturing using yeast, bacteria, or algae to produce cosmetic ingredients and fragrance compounds with greater consistency. I think these two approaches are going to significantly contribute to ingredient discovery in the coming years.

10) If you look at how haircare has evolved over the past few years, the biggest shift has been a move away from hair as just a fiber and toward the intricacies of the scalp. That’s really the foundation of the whole “skinification” trend. What we’re seeing now is a much more biologically informed approach, one that recognizes that healthy hair starts with the follicle, and the follicle lives in the skin.

So it’s not surprising that we’re now seeing skincare ingredients like niacinamide, hyaluronic acid, and peptides showing up in scalp treatments and shampoos. They reflect a shift toward addressing things like barrier function, microbiome, and inflammation on the scalp. We’re seeing more emphasis on clinical-style claims like hair density, shedding reduction, and follicle health, and that I think that brings with it higher expectations for performance. You can’t just borrow the language of skincare without also doing the work to support it. Looking ahead, I think this “root cause” framing will continue to expand. And the "skinification" trend won’t stop with haircare. Body care, intimate care, even oral care. The opportunity is real, but it’s going to depend on applying the skincare product development mindset with a solid understanding of both formulation and physiology.
