I. Structural and Functional Differences
| Item | Ampoule | Glass Bottle |
| Primary Use | Typically used for high-concentration, single-use serums or active raw solutions. | Commonly used for daily skincare products, such as toners, lotions, serums, creams, etc. |
| Opening Method | Mostly designed for one-time opening or push-to-release structures (e.g., micro-pressure bottles). | Reopenable and reclosable; mostly paired with droppers, sprayers, or vacuum pumps. |
| Capacity | Usually small capacity (1–20ml), for immediate use to keep freshness. | Large capacity (30–100ml), suitable for long-term use. |
| Preservation | High sealability prevents effective ingredients from oxidation and contamination. | Varies by design; protection can be enhanced if vacuum pump heads are used. |
※ Note: According to Taiwanese regulations, “glass ampoule containers shall not be used as cosmetic containers.” The purpose of this regulation is to ensure consumer safety,
as these “one-piece, breakable” glass containers can cause accidental injuries during operation and are easily confused with ampoules used for injections. Furthermore,

II. Material Differences and Characteristics
| Material Aspect | Ampoule | Glass Bottle |
| Material Type | Mostly borosilicate glass or aluminosilicate glass, which is highly resistant to acids, alkalis, and high temperatures. | Can be made of soda-lime glass or borosilicate glass; strength is slightly lower. |
| Transparency | Mostly clear or amber, used to monitor liquid color and protect light-sensitive ingredients. | Highly customizable with transparent, frosted, or colored glass for a variety of appearances. |
| Airtightness | Almost completely hermetically sealed, providing high stability for active ingredients. | Varies depending on the bottleneck design; requires gaskets or vacuum structures. |
| Chemical Resistance | Highly resistance; suitable for packaging acidic formulations or those containing active molecules. | Medium to high, depending on the glass grade and coating treatment. |
| Reusability | Generally for single-use. | Reusable or recyclable. |
III. Appearance and Brand Image
