Lecos
Engineered for stability, luxury brand aesthetics, and absolute formula protection.
In the contemporary prestige cosmetic and dermatological industries, the integration of advanced skincare formulations requires packaging that transcends mere aesthetics. At Lecos Glass, we recognize that packaging is a critical extension of the formulation chemistry itself. The term "Airess Glass Jars" defines a category of high-performance glass packaging engineered to preserve high-potency, oxygen-sensitive actives such as L-ascorbic acid, retinoids, peptides, and botanical lipids.
Unlike standard soda-lime cosmetic jars, our high-quality glass jars are manufactured with precise chemical compositions that prioritize hydrolytic resistance. This ensures that the pH level of the product remains unaffected throughout its shelf life, preventing chemical leaching and preserving the integrity of clean-beauty formulas. By minimizing volatile organic compound (VOC) interaction and preventing gas permeation, our premium glass solutions provide an absolute physical barrier that plastic alternatives simply cannot replicate.
Specially processed glass that guarantees minimal alkali release, safeguarding formulas against degradation over extended shelf lives.
Zero chemical reactions between container walls and botanical lipids, high-acid emulsions, or clinical skincare actives.
100% infinitely recyclable material composition, lowering the scope-3 emissions for global beauty brands and cosmetic houses.
Lecos Glass operates at the cutting edge of industrial glass manipulation. For more than 10 years, we have worked with major global cosmetics brands to deliver custom bottle molding and advanced deep-processing options.
Our industrial production capabilities include high-precision frosting, complex electroplating, automatic lacquer spraying, decal transfers, and precise multi-pass silk-screen printing. We maintain strict physical tolerance controls during glass drawing and blowing, which reduces glass thickness variance and optimizes mechanical strength against drop testing and thermal shock.


Our commitment to excellence is reflected in our strict adherence to the core values that support the global cosmetics market.
Every cosmetic jar is subjected to stringent visual check routines, weight-bearing evaluations, and physical stress tests to ensure flawless performance on active filling lines.
By optimizing our manufacturing efficiency and raw material sourcing networks, we offer competitive direct-from-factory pricing that maximizes brand profitability.
From initial design conceptualization and custom mold drafting to shipping coordination and custom clearances, our team is committed to supporting your project lifecycle.
The global packaging sector is undergoing a major shift away from single-use plastics towards sustainable, inert materials. Glass packaging stands at the forefront of this movement. Premium cosmetic and skincare brands must navigate high regulatory standards regarding plastic chemical migration, microplastics, and overall carbon footprints. The transition to high-quality glass jars represents an effective method for premium brands to reduce their scope 3 emissions while enhancing their perceived value on retail shelves.
Our advanced glass formulations are designed for compatibility with complex ingredients, including retinol, low-molecular-weight hyaluronic acids, high-dose Vitamin C serums, and clean-label cosmetic formulations. These raw active formulas require protective containers to prevent oxidation and chemical reactivity, which are primary factors in formulation breakdown. Our physical barrier systems provide complete protection against UV radiation and gas ingress, extending shelf-life and ensuring product efficacy.
Lecos Glass ensures compliance with the primary international cosmetic packaging regulations. All shipped batches undergo rigorous testing to comply with FDA GRAS (Generally Recognized as Safe) conditions, European Commission Regulation (EC) No 1223/2009 for cosmetic products, and heavy metal limits dictated by European Directive 94/62/EC (and state-level TPCH limits in the USA).
Our supply chain verification processes provide certified analyses for all production runs, giving your quality control teams confidence that our containers are free of heavy metal contamination and safe for premium formulations.
Our state-of-the-art facilities combine traditional craftsmanship with advanced automated systems to achieve high-precision cosmetic glass production.
Sourcing silica sand, soda ash, and limestone of verified purity to ensure optimal transparency and chemical stability.
Embodying precise geometry via automated IS (Individual Section) glass forming machines with minimal neck variation.
Relieving internal stresses in precision thermal ovens to prevent fracturing under high-speed filling line pressures.
Lecos Glass is committed to advancing the development of high-performance glass packaging. Our research and development roadmap focuses on three main technological improvements designed to optimize product protection and environmental performance:
Ultra-Lightweight Structural Engineering: Through finite element analysis (FEA) and optimized distribution of glass material, we are targeting a 20% reduction in average container weight while maintaining break resistance. This reduction will directly decrease shipping costs and lower fuel consumption during international transport.
Advanced Eco-Friendly Surface Treatments: We are scaling our chemical vapor deposition (CVD) methods and moving away from traditional heat-cured coatings to low-energy UV-curable and water-soluble finishes. This transition helps eliminate volatile emissions from our finishing lines and produces products that are easy to recycle in standard municipal recycling systems.
Innovative Bio-Based Integration: In partnership with closure manufacturers, we are designing composite cap seals that utilize plant-derived resins instead of fossil-fuel plastics. This allows us to offer packaging sets that minimize the use of non-renewable petroleum resources.
Our jars are designed to support high-end active ingredients such as retinols, organic ferments, and Vitamin C compounds by preventing degradation from oxygen and light.
Featuring certified lead-free glass and BPA-free closures to support compliance for clean beauty brands seeking to meet safety regulations.
Utilizing high-strength packaging, double-wall corrugated dividers, and vacuum-sealed polybags to ensure safe delivery and prevent scratching during transit.
