## In one minute

### The lamellar interface is a shared template
The dominant answer to holding oil and water together is the lamellar liquid crystal: an emulsifier and a fatty alcohol packing into stacked sheets at the interface. One filing states the design rule outright — choose polyglycerol fatty acid esters so the critical packing parameter sits near 1 [1]. Others reach the same architecture from different starting points: a glutamate-based emulsifier with cetyl, stearyl or behenyl alcohol [2]; a glucoside or olive-ester emulsifier paired 2:1 with dioctyldodecyl lauroyl glutamate to raise the regularity of the cross-flower lamellae [3]; a sucrose stearate, glyceryl stearate and PEG-60 sorbitan stearate blend that mimics the stratum corneum as a "second layer of skin" [4]. A self-assembling variant forms Maltese-cross liquid crystals at the interface during cooling [5], and L'Oréal claims the same lamellar texture for stability at room temperature for at least five months [6].

The point is not that one of these is better. It is that the construction has become a template: unrelated applicants file the same stacked-sheet architecture with the emulsifier swapped. Cosmax and Dongguk University describe an oil-free, water-dispersible multilayer lamellar structure with a 4.3 nm interlayer spacing [7].

### What changes hands is a clinical position, not a formula
The acquisitions of the past two years are of brands that own a claim a buyer thinks it can defend. L'Oréal took a majority stake in Medik8 as a route into the fast-growing dermatological skincare market. Galderma agreed to buy ZO Skin Health for 1.5 billion, a physician-dispensed brand with roughly 330 million in net sales, sold through more than 16,500 physician, medical spa and online accounts in over 40 countries. Bridgepoint bought Obagi Medical for up to $460 million, naming its scientific heritage and physician relationships, and calling physician-dispensed skincare one of the fastest-growing segments of dermatology and aesthetics. Hindustan Unilever paid about $350 million for Minimalist, an actives-led digital brand, and Wipro bought into Dermatouch for its science-led direct-to-consumer position. Henkel took Olaplex and Estée Lauder took a stake in 111Skin in the same half-year.


### The carrier is where the filing mass concentrates
Across otherwise unrelated payloads, the engineering has moved to what carries the active. P&G claims polymer capsules defined by a burst-strength range and a shell between roughly 20 and 400 nm. Givaudan files a family of core-shell microcapsules built around a hydrated polymer phase and an aminosilane interface. Tagra builds multi-layer microcapsules for vitamin C and rutin specifically. A university group reports a Pickering system encapsulating idebenone, psoralen and squalane above 90% efficiency. A polymer carrier is claimed for raising retention of a volatile active on skin, with the carrier itself as the product. The same problem is solved repeatedly by applicants who do not otherwise compete, which is the clearest statement in the filings about where they think value sits.


### Solid particles have replaced the surfactant
A second line drops surfactant molecules altogether and stabilises the interface with particles. Microcrystalline cellulose with a Sphingomonas fermentation extract and a lysate does the job for sensitive skin. Plant and mineral particles follow: green-thorn pomace powder, broken-cell-wall pine pollen, surface-modified volcanic mud, and halloysite nanotubes electrostatically paired with fucose and chitosan.


### The claim has become the regulated object
The compliance surface widened on several fronts at once. In the US, MoCRA's registration and listing obligations set deadlines for facilities and products, and a certification standard was introduced specifically to give finished products defined safety-substantiation benchmarks aligned to it. The EU capped retinol concentrations in facial and body products. India's drug regulator cancelled registrations for products above its salicylic acid limit, and Vietnam suspended 162 products for failing to produce product information files.


### The device work is building a consumable, not proving a dose
The device filings concentrate on the interface that ties a refill to its seller. Hironic claims a handpiece that reads a cartridge's unique number and activation status and tracks an operation count against a limit. Dimi Life claims a consumable unit whose chip stores consumable information and preset care modes, with the control unit managing extrusion order, timing and quantity. L'Oréal claims a system that selects and mixes booster and base compositions from user input and skin analysis. A microcapsule release device bursts its capsules as the solution flows past a heating element. The one registered trial in the area runs a home device with no cartridge or pump described. The effort is going into the lock between device and refill, not into showing the metered dose does anything a fixed dose would not.


### The cargo is what gets engineered
The actives worth carrying are the ones that misbehave. Ceramides precipitate, and the formulation literature is explicit that undissolved ceramide is counterproductive to barrier repair. Salicylic acid recrystallises. CBD is stubbornly lipophilic. The answers are encapsulation, inclusion complexes and solvent systems tuned to stop precipitation: glabridin wrapped in a self-assembled lipid bilayer under 150 nm, dextrin esters synthesised at a controlled degree of substitution to act as oil-in-water emulsifiers, a Pickering emulsion whose stated purpose is to keep plant vesicle structures from degrading, and microcapsules with a solid polymer shell around an oil core.


### The one new active to reach the market arrived as a drug
Bemotrizinol entered the US market in June 2026 as the first new UV filter cleared in more than twenty years, and Neutrogena put it into two facial sunscreens within months. It reached the shelf as an over-the-counter drug ingredient, with a concentration limit and a monograph behind it, not as a cosmetic active. That is the only route by which a genuinely new molecule has entered this market in the period, and it is the route the composition work does not take. A New Zealand brand treats its US over-the-counter registration as the asset that opens pharmacy distribution.


## Overview


### The active is available to anyone who wants to buy it
Ferments, niacinamide, salicylic acid, minoxidil, ascorbic acid, squalane, zinc oxide and the common botanical extracts are off-patent or purchasable, and any competent formulator can build the base. The filings in each area have moved off the active and onto the engineering around it: encapsulation, penetration, stability, and the claim. The recurring biological targets are the same across otherwise unrelated filings — elastase, collagenase, MMPs, tyrosinase, 5α-reductase, the barrier proteins. The biology is well described in cells and animals. Controlled human evidence is thin nearly everywhere.


## Research

### "Exosome" now names two different objects
The vesicle work is filed under one word and contains two unrelated things. One is a plant extraction process: homogenise plant tissue, centrifuge in stages, ultrafilter through a 10–100 kDa membrane, or filter through 0.8 and 0.45 µm membranes before concentrating. The other is a surface-engineered vesicle, modified with dioleoylphosphatidylserine, DOPE and hirudin to cross the stratum corneum and reach the basal layer.


### Recombinant collagen has moved to hydroxylation and helix stability
The collagen filings are no longer about expressing the protein. They are about making it fold and survive. One reports secretion of a type I fragment at up to 23 g/L with over 80% purity from Pichia; another reports 15 g/L of full-length humanised type III. The current work co-expresses proline hydroxylase with glycyl- and prolyl-tRNA synthetases so the triple helix forms correctly, reaching 3.16 g/L at 99.54% purity. Others claim triple-helix constructs that resist enzymatic degradation or stay stable after an hour at 95 °C.


### Keratin and biomass: deposited strains and characterised enzymes
A parallel bioprocessing line turns waste protein into peptides. Bacillus velezensis CHB200, deposited at DSMZ, decomposes fish scales into polypeptides and amino acids as an alternative to acid hydrolysis, and a sibling strain handles duck feathers and fish scales together. Collagenase-producing strains are deposited for tissue dissociation and collagen hydrolysis,.


### Sunscreen: the filter set is fixed, the work is dispersion and photostability
No new filter chemistry appears. The work is on getting the existing filters to stay where they are put. L'Oréal claims a mineral oil-in-water emulsion at SPF 30–55 stabilised by a C12-22 alkyl acrylate/hydroxyethylacrylate copolymer thickener. Cosmax disperses zinc oxide in a water-in-oil base using a glutamate surfactant and a hectorite thickener to stop aggregation. Colgate-Palmolive and Lubrizol blend two zinc oxides with different critical wavelengths in a defined ratio to reach a UVA/UV ratio above 0.70. Rohm & Haas adsorbs phosphate-functional copolymer particles onto metal oxide surfaces to raise SPF.


### Cleansing: selectivity is the technical bet
The antimicrobial actives are old — quaternary ammonium compounds, tea tree oil, hypochlorous acid, plant extracts. The new claim is that they can be made selective. A tea tree oil complex is filed to act on S. aureus, E. coli and Pseudomonas while leaving S. epidermidis and Corynebacterium intact. Beiersdorf pairs levulinic acid with anisic acid to reduce anaerobic bacteria and spare aerobic ones. A Sapindus ferment is claimed to inhibit C. acnes, Malassezia furfur and S. aureus while preserving S. epidermidis. LG Household & Health Care uses thiamine HCl to inhibit porphyrin production and hyaluronidase activity in the skin flora. Short-chain fructooligosaccharides with native starch are claimed to stimulate S. epidermidis while limiting C. acnes, and Gojo uses Bacillus strains to raise antimicrobial peptide production.


### Barrier oils: enzymatic restructuring, not new molecules
The bulk of a barrier oil is bought squalane or a seed oil, so the defensible work is the process that changes it. Camellia oil is restructured by immobilised lipase transesterification, replacing oleic acid with gamma-linolenic acid and dispersing the lipids at nanoscale to improve penetration. Squalane is extracted from camellia seed using a silver-salt eutectic solvent coupled with negative-pressure cavitation, and the result is measured as stratum corneum moisture over eight hours against olive squalane. Argan kernel oil is enzymatically hydrolysed at pH 5.0–5.5 to improve dispersibility and phenolic bioavailability. Linseed oil is refined to retain alpha-linolenic acid, gamma-linolenic acid, squalene and sterols through the deodorisation step. Hydrogenated castor seed oil is processed to raise SOD activity and subjective hydration.


### Devices: the metering hardware is built, the cartridge is the business model
The handpiece engineering is specific. Filings describe a cam-driven dual pump that sprays treatment material and sucks it back through a separate circuit, a hydradermabrasion head with a supply canister, a waste receptacle and an orientation sensor that stops the pump when the device is angled wrongly, and a multi-reservoir system with a selection valve, a positive-displacement pump and a vacuum inlet returning waste to a chamber. A parallel line reads the skin to control the treatment: projections with integrated sensors that decide whether to fire a light pulse, a device that analyses skin images to deliver targeted treatment, and one that detects skin quality and adjusts recommendations from it.


### Freeze-dried masks and solid bars: the process is the invention
In the mask work the value sits in the substrate and the drying step. A three-layer freeze-dried mask places the functional ingredients in one layer and a biopolymer slow-release layer on the other side, applied by two rotary screen coaters and pre-dried to remove 70–80% of moisture before vacuum freeze-drying. A sibling filing claims the pre-drying tunnel and the turning guide that inverts the web between coatings. A bird's nest peptide mask specifies slow freezing at 1–10 °C/min and a two-stage sublimation over 30 hours. A collagen mask cross-links thermally to avoid a cross-linking agent and stay non-tearable.


### Wound healing: an international family with no human testing
One applicant has built an international family around a Plectranthus amboinicus and Centella asiatica pair with a moisture-retaining polymeric biomaterial, filed across multiple jurisdictions,,. The claimed advantage is moisture retention of 97.1–100%, benchmarked against two commercial products. The mechanism claimed is a moist environment that supports angiogenesis and collagen synthesis.


### Specification by ratio and marker
The commercial filings in the botanical work do something the academic formulation literature does not: they define the product by content rather than by ingredient list. Unilever claims coffee seed oil with 12-hydroxystearic acid at a weight ratio between 1:5 and 15:1. Cosmax claims a coffee, grape seed and coconut oil blend at defined mass ratios extracted with supercritical CO2. Givaudan claims a mango leaf extract in a propanediol-water carrier with named phytomarkers — mangiferin, maclurin-glucoside, gallotannin-glucoside and iriflophenone-glucoside.


### Tanning: two mechanisms, and the screening work points at pigment loss
The tanning filings split cleanly. One line is Maillard chemistry: dihydroxyacetone with an aromatic sulfonate to drive melanoidin polymerisation toward a bronze hue. The other modulates the melanin pathway itself — a methyl-group donor combined with an acetyl-CoA donor raises epidermal melanin through Tyrp1 expression and MC1R and phosphorylated CREB levels, and selective tri- and tetrapeptide MC1R agonists stimulate melanin synthesis and DNA repair without off-target receptor activation.


### What the architecture has behind it
The lamellar premise has one mechanistic study and one small clinical companion. Transmission electron microscopy showed a phosphatidylcholine multilamellar cream restoring the lipid bilayers of the stratum corneum and raising ceramide and free fatty acid levels over 14 days, without altering cholesterol. A double-blind study of the same cream after tape-stripping, in 14 participants, found improved barrier repair, hydration and microbiome diversity against a basic placebo.


## Market

### Exosome is being priced before it is defined
The exosome skincare category is projected to grow from about 852 million in 2025 to nearly 4 billion by 2035, with clinics and professional channels taking the largest share — a supplier-side projection, made while the trade press is openly asking whether the products contain what the word implies. Demand is strong enough to justify a dedicated manufacturing plant, and a platelet-derived exosome product has been allowed to proceed to a Phase 1 dermal-injection trial. One supplier has published a framework for judging such products on formulation, stability, safety and clinical evidence.


### Dose control is being sold ahead of the evidence that it matters
Aptar launched an auto-loading dropper aimed at more accurate skincare dosing, and a medical-device engineer is now selling smart applicators as an active part of skincare performance rather than a passive container. Philips launched a premium LED mask positioned on clinically proven light technology.


### The channel that converts is the channel being policed
Foundation sales on TikTok Shop reached $15.82 billion in US GMV in 2025, up 108% year on year, the fastest-growing retail channel in beauty. Brands are following it: a L'Oréal-owned K-beauty brand launched there as its US expansion route, and a Korean brand raised $6.5 million to scale through Amazon and TikTok Shop. The audience is doing the selling — 71% of 18-to-26-year-olds say they would buy a product recommended by their favourite influencer.


### Capacity is consolidating into fewer, larger suppliers
Evonik opened a dedicated beauty science and innovation centre in Shanghai. Kolmar Korea is closing its Beijing plant and investing about 170 billion won to expand its Sejong site, which serves more than 4,500 clients. C&C International is building a new plant to move from colour cosmetics into basic skincare as a comprehensive ODM. Clariant is expanding manufacturing in China and Cosmax is expanding microbiome research there.


## Strategy

### Collagen work has moved past expression to folding and survival
The collagen filings are no longer about making the protein. They are about making it hold its shape. One co-expresses proline hydroxylase with the collagen so the triple helix forms, reaching roughly 40% hydroxylation and a tenfold gain in cell adhesion over a commercial comparator. Another refolds inclusion-body collagen through a chaperone system, adding DnaK/DnaJ at the start and GroES/GroEL once the urea falls. Others claim a helix that resists enzymatic degradation, one stable after an hour at 95 °C, and a type III–type X chimera whose C-terminal non-helical region supplies anti-hydrolysis stability. Expression is settled; the contest is over whether the product arrives folded and survives formulation.


### Selectivity is the field's one new mechanism bet, and the large firms are filing it
The antimicrobial actives are old, but the claim attached to them is new: an agent that kills a pathogen and spares the skin's own flora. Unilever claims sapienic acid with 12-hydroxystearic acid for selective activity against S. aureus that preserves coagulase-negative staphylococci, and separately a biotin-binding compound with a biotin precursor to promote S. epidermidis over S. hominis. Beiersdorf pairs levulinic and anisic acids to reduce anaerobes and spare aerobes, and files live S. epidermidis and S. warneri strains that suppress S. aureus. LG uses thiamine HCl to inhibit porphyrin production and hyaluronidase activity in the flora; Gojo uses Bacillus strains to raise antimicrobial-peptide production; a fructooligosaccharide-and-starch system stimulates S. epidermidis while limiting C. acnes. This is the one place where the filings propose a mechanism rather than a formulation, and it is being staked out by multinationals rather than by the small formulators who fill the rest of the actives area.


### The enforceable botanical filings specify content, not ingredient lists
The commercial filings in the botanical work define the product by what is in it, measured, rather than by a list of herbs. Unilever claims coffee seed oil with 12-hydroxystearic acid at a defined weight ratio. Cosmax claims a coffee, grape seed and coconut oil blend at defined mass ratios extracted with supercritical CO2. Givaudan claims a mango leaf extract in a propanediol-water carrier with named phytomarkers. Against that, the academic and individual filings define a cream by its ingredient list. A ratio and a marker list can be enforced; a list of herbs cannot. The direction of effort in this corner is toward making a botanical specifiable.


### A densely filed wound-healing family with no human testing
One applicant has built an international family around a Plectranthus amboinicus and Centella asiatica pair with a moisture-retaining polymer, claiming moisture retention of 97.1–100% against named commercial comparators. The mechanism claimed is a moist environment supporting angiogenesis and collagen synthesis. There is no registered human testing behind it. This is the clearest case of effort that has gone into claiming and protecting a combination without going into proving it in people.


### The selling question is answered in journals, not in filings
The buying-driver work sits almost entirely in marketing research: a brand ambassador that moves purchase only through trust, a celebrity endorser that moves decisions where electronic word of mouth does not, and one study finding that perceived overclaim does not reduce trust at all. The patent record is nearly silent on how a skincare product is sold. Firms publish the answer and buy it through marketing spend; they do not file on it. That is a direction of effort as much as any filing is.
