As exclusive containers for thick-textured skin care products like creams, milky creams, and gels, face cream jars need to address four major challenges: "freshness locking through sealing + anti-contamination + easy access + texture compatibility". Four mainstream sealing technologies are designed for different skin care needs, ensuring that face creams maintain their activity and texture from opening to use-up:

1. Vacuum Negative-Pressure Face Cream Jars: "Freshness Guardians" for High-Activity Ingredients

**

Specifically designed for high-end face creams with easily oxidizable ingredients such as peptides, pro-Xylane, and plant extracts, this type of packaging accounted for over 65% of applications in luxury skin care lines in 2024:

• Negative-Pressure Freshness-Locking System: Adopting a "piston-type lifting inner liner + one-way exhaust valve", pressing the lid during the first use expels air from the jar, creating a negative-pressure environment of -0.02MPa. This reduces the oxidation rate of active ingredients to below 5% and maintains an efficacy retention rate of over 90% within 6 months after opening.

• Anti-Contamination Dispensing Design: Equipped with a "press-to-dispense pump", it allows direct dispensing by pressing without opening the lid. Each dispense volume is precisely controlled at 0.5g (about the size of a soybean), avoiding contamination from hand contact. The pump is built with an antibacterial silicone pad, achieving an antibacterial rate of 99.9% to inhibit mold growth.

• Texture Compatibility Details: The inner liner is made of food-grade PP material, which has strong compatibility with thick textures like milky creams and ointment-like creams, with no risk of ingredient leaching. The transparent jar body paired with a gold lid aligns with the visual positioning of high-end beauty products, enhancing brand texture.

2. Magnetic-Sealed Face Cream Jars: "Ritual Choice" for Light Luxury Skin Care

Focusing on the mid-range skin care market that values the ritual of use, it enhances the opening and closing experience through magnetic design, suitable for soothing face creams containing natural essential oils and aromatic ingredients:

• Magnetic Control Sealing Structure: The lid is built with a strong neodymium-iron-boron magnet (with a suction force of 8N), which accurately adheres to the metal ring on the jar body. A "click" sound is heard when closing, creating a strong sense of ritual. The sealing surface is equipped with a food-grade silicone ring, ensuring no leakage even when inverted for 72 hours, effectively isolating air and dust.

• Aroma Retention Design: The jar body is made of double-layer light-proof PP material, blocking 95% of ultraviolet rays to prevent aromatic ingredients from volatilizing when exposed to light. The jar mouth has a diameter of 6cm, paired with a customized spatula (placed in the groove on the top of the lid) for easy access without cross-contamination. The spatula head is designed with anti-slip patterns to prevent the cream from slipping during scooping.

• Balance of Aesthetics and Practicality: The lid can be customized with embossing and gold stamping techniques, such as floral patterns and brand logos, to fit the light luxury positioning. The jar body weighs 80-100g, allowing one-handed opening and closing effortlessly, making it suitable for daily placement on the dressing table.

3. Wide-Mouth Dust-Proof Face Cream Jars: "Cost-Effective Choice" for Basic Skin Care

**

Targeting the mass basic skin care market (e.g., students, entry-level consumers), it is suitable for moisturizing face creams with stable ingredients such as glycerin and ceramides, with a capacity mostly ranging from 50-100g:

• Simple Sealing Design: Adopting a "screw cap + single-layer silicone ring" structure, it meets the daily dust-proof and moisture-proof needs when tightly screwed. A dust-proof sheet is built inside the lid to reduce dust falling into the jar when opening, extending the shelf life of the face cream.

• Easy Access Optimization: The jar mouth has a diameter of 5-7cm, facilitating access with hands or a spatula, especially suitable for thick ointment-like creams. The transparent jar body allows clear visibility of the remaining amount, avoiding "empty jar anxiety". Some models are equipped with scale lines for easy control of each use amount.

• Cost-Effective Material: The jar body is made of food-grade PET material, which has strong impact resistance (no damage when dropped from 1.5 meters). Its production cost is 40% lower than that of vacuum jars, fitting the positioning of affordable products. The recyclability rate reaches 90%, in line with environmental trends.

4. Compartmentalized Storage Face Cream Jars: "Convenient Steward" for Multi-Effect Skin Care

**

Solving the storage problem for consumers using multiple face creams simultaneously (e.g., day cream, night cream, eye cream), it has achieved a growth rate of 58% in the functional skin care field in recent two years:

• Independent Compartment Structure: Adopting a two-compartment or three-compartment design, each compartment has a capacity of 15-30g, with independent sealing to prevent flavor mixing. Clear labels (e.g., "Day", "Night", "Eye") are set between compartments to avoid confusion during use. Some models are equipped with time-scale stickers to remind users of the usage period after opening (e.g., use up within 3 months).

• Precise Dosage Control Details: Each compartment is paired with an independent small spatula, with a spatula head capacity of 0.2-0.3g (suitable for eye cream and local face cream), avoiding dosage waste. The spatula is stored in the built-in groove of the jar lid for easy access and to prevent loss.

• Space Optimization Design: The overall size is controlled at 8cm×8cm×5cm, occupying only 1.5 times the space of an ordinary face cream jar, saving dressing table space. The jar bottom is equipped with an anti-slip silicone pad, preventing 倾倒 when stacked, suitable for small apartments or travel.

II. Face Cream Jar Materials: Dual Standards of Safety and Texture

Directly in contact with facial skin care products, face cream jar materials need to meet three requirements: "non-irritating + anti-aging + texture compatibility". In 2025, the application ratio of environmentally friendly and functional materials has exceeded 88%:

Innovative Material Breakthroughs: Lancôme has launched "bio-based plastic face cream jars", using bio-based materials extracted from corn starch, which are degradable in the natural environment within 2 years while maintaining good sealing performance; Kiehl's has adopted a "recycled glass + wooden lid" combination, where the glass contains 50% recycled glass and the wooden lid is made of FSC-certified sustainable wood, balancing environmental protection and high-end texture.

III. Scenario-Based Design: Full Adaptation from Daily Use to Special Needs

High-quality face cream jars optimize the skin care experience by segmenting scenarios to better meet consumers' actual needs:

1. Daily Skin Care Version (50-100g): Balancing Convenience and Durability

• Sensitive Skin-Friendly Design: The inner wall of the jar body is treated with "no fluorescent agents" to avoid irritating sensitive skin; paired with a "sterile spatula", the spatula head is disinfected by ultraviolet rays for direct use after opening, reducing the risk of bacterial contact; some models have "dosage prompts", marking the recommended dosage each time to avoid excessive use that may burden the skin.

• Eye Cream-Specific Details: With a capacity of 15-20g and a jar mouth diameter of 3cm, it is paired with a mini spatula (spatula head diameter of 0.8cm) for precise access to the dosage required by the eye skin; the jar body is marked with a "refrigeration label" to remind users with sensitive skin that it can be refrigerated to enhance the soothing effect.

IV. Purchasing Guide: 4 Steps to Choose a High-Quality Face Cream Jar

1. Check Sealing Performance: Invert a new jar for 24 hours after tightening to observe if there is leakage; a qualified vacuum jar should make no "suction sound" when pressed; if the cream rebounds slowly after pressing, the seal may be invalid; a good magnetic-sealed jar should have no loose noise when shaken after adsorption.

2. Choose Suitable Materials: For products containing active ingredients (e.g., retinol, vitamin C), select light-proof frosted glass or vacuum PP jars; for sensitive skin, prioritize materials without fluorescent agents and with antibacterial properties; for those pursuing texture, choose high-transparency PETG or recycled glass jars; for travel, select anti-extrusion PP jars.
