Dual-Chamber Mask Customization
05 Dec, 2025 2:25pm
When compartmentalized fresh-locking becomes a new keyword in the mask market and the demand for "fresh-effect skincare" drives the iteration of packaging technology, the cosmetics industry is ushering in a product innovation wave centered on "activity + convenience". According to industry observations, since 2024, dual-chamber masks have achieved significant growth in segmented tracks such as sensitive skin repair, late-night emergency care, and early anti-aging, as they can address pain points of traditional masks like easy inactivation of active ingredients and limited usage scenarios. Social media data shows that the volume of discussions around "mask technology" - related keywords increased by over 57% from 2022 to 2024, with dual-chamber design and fresh-locking technology becoming focal points of consumer discussions. Against this trend, Dongguan Keyan Cosmetics Co., Ltd., relying on multiple core patents for dual-chamber masks and 13 years of OEM experience, provides brands with a full-chain customization solution from formula compartmentalization to packaging design.
Patent Protection: The Hardcore Support for Dual-Chamber Technology
The core competitiveness of dual-chamber masks lies in compartmentalized conduction technology and fresh-locking systems. Dongguan Keyan has established a sound patent layout in this field. Up to now, the company has obtained 5 patents related to dual-chamber masks, including the invention patent of "a dual-bag mask bag" and utility model patents such as "insert-type conduction part for dual-bag mask bags" and "rotary conduction part", building a technical barrier from packaging structure to user experience. Among them, the insert-type conduction part adopts an independent sealing sheet design, which can effectively prevent the mask liquid from flowing in advance, and the pull-out opening method avoids the pollution risk of traditional tear-open packaging; the rotary conduction part innovatively uses an occlusal structure of connecting grooves and connecting through-holes, allowing users to control the mixing of liquid and mask by rotating the knob, which is convenient to operate and has excellent sealing performance.
The application of these patent technologies has realized three core advantages of dual-chamber masks: first, active fresh-locking, which stores easily inactivated ingredients (such as blue copper peptide and retinol derivatives) separately from the base liquid and mixes them instantly when used, ensuring that the retention rate of ingredient activity is increased by more than 30%; second, aseptic protection, the sealed separate packaging of mask liquid and dry mask cloth avoids bacterial growth due to long-term soaking, and the mixing process is completed in a closed environment to reduce external pollution; third, precision proportioning, through the pre-filled compartment design, the golden ratio of functional ingredients and carrier liquid is realized, avoiding the effect fluctuation caused by uneven manual deployment.
Formula Compartmentalization: Precisely Matching Segmented Needs
The core of dual-chamber mask customization lies in the "scientific compartmentalization of functional ingredients". Relying on cross-category R&D experience, Dongguan Keyan has created a flexible formula combination system. The company's R&D team has designed various compartmentalization modes such as "water + powder", "oil + water", and "essence + mask cloth" for different skincare scenarios: for sensitive skin repair needs, it adopts a dual-chamber design of "soothing essence + blue copper peptide freeze-dried powder", which is mixed and activated when used to avoid the提前 reaction of blue copper peptide with other ingredients; for late-night emergency scenarios, it has developed the combination of "revitalizing stock solution + niacinamide freeze-dried tablets", which stores high-concentration niacinamide through compartmentalization to reduce photodegradation and inactivation; in response to the trend of oil-based skincare, it has innovated the dual-chamber formula of "plant essential oil + moisturizing water", which is combined with instant emulsification technology to solve the problem of sticky usage of traditional oil masks.
In terms of ingredient application, Dongguan Keyan deeply integrates patent technologies with popular raw materials. For example, the centella asiatica extract and alkaligenes polysaccharide components in its oxygen mask patent can be combined with dual-chamber technology to create an innovative structure of "repair liquid + oxygen generation chamber", which releases oxygen bubbles to promote ingredient penetration when used; the compartmentalized design of baking soda and citric acid in the carbonic acid mask patent realizes the "ready-to-use" carbonic acid bubble effect, avoiding the problem of premature foaming and failure of traditional carbonic acid masks. In 2025, the dual-chamber repair mask customized by the company for cooperative brands successfully completed the filing, and gained recognition in the segmented market through the technical claim of "liquid-mask separation + aseptic mixing".
Packaging Customization: The Dual Expression of Aesthetics and Environmental Protection
The packaging of dual-chamber masks is not only a technical carrier but also a visual symbol of brand differentiation. Dongguan Keyan deeply understands the market logic of "packaging is experience" and provides customized customers with diversified packaging solutions. In terms of structural design, it supports various forms such as flat bags, stand-up bags, and special-shaped bags. According to the brand positioning, transparent windows can be selected to show the liquid-mask separation state, or matte film coating can be used to enhance the high-end texture; in terms of material selection, food-grade PET/PE composite film is used to ensure puncture resistance and barrier properties, and at the same time, FSC-certified environmentally friendly paper is promoted for outer boxes to respond to the global sustainable packaging trend.
In response to young consumers' pursuit of "convenient aesthetics", the company has also launched mini dual-chamber designs made of recyclable materials to meet the portable needs of travel, office and other scenarios; for high-end brands, it provides customized options such as metal texture conduction parts and gold stamping process outer boxes, so that the proportion of packaging costs can be flexibly controlled in the range of 15%-30%. This three-dimensional packaging strategy of "technology + aesthetics + environmental protection" not only conforms to the research conclusion in the "Global Beauty Consumption Trend Report" that 72% of consumers pay attention to packaging design but also fits the ESG strategic layout of international brands.
Full-Chain Service: Landing Support from Laboratory to Market
The customization process of dual-chamber masks involves multiple links such as patent technology application, formula compatibility testing, and packaging mold opening. Dongguan Keyan has built a professional project service system. The company has a 13,000-square-meter GMP-grade dust-free workshop, equipped with special filling machines and sealing detection equipment for dual-chamber masks, which can realize seamless connection from sample proofing to large-scale production. For start-up brands, it provides small-batch trial production services (minimum order quantity as low as 5,000 pieces) with formula adjustment suggestions; for mature brands, it can achieve an annual production capacity of one million pieces through automated production lines and support flexible production of multiple SKUs.
In addition, the company also provides regulatory compliance and market education support: assisting brands in preparing filing materials for dual-chamber products to ensure that compartmentalization claims comply with cosmetics regulatory requirements; through the cooperation resources of its Keyan Yuemeng brand and training schools, providing customers with scenario-based training on product use, such as the full-process teaching of "instant mixing - mask application method - effect demonstration" for dual-chamber masks, helping brands convey technical value at the terminal.
Conclusion: A Customization Partner in the Fresh-Effect Era
