I.Poor design, difficult to use Excessive residue at the bottom of the bottle: Especially for thick lotions, creams, or foundations, the non-pressable bottle design results in a large amount of product residue remaining on the bottle walls and bottom, causing waste. Dropper too short: The dropper for serums is not long enough to reach the last bit of product at the bottom of the bottle. Insufficient pump pressure: For airless bottles, improper pressure may prevent the product from being fully dispensed, or the pump may malfunction from the start. Inadequate opening design: Cream jars may have openings that are too narrow, making it difficult to insert fingers; cream jars may lack a spatula or a fixed spatula, leading to contamination; dropper openings may be too large, resulting in excessive dispensing at once. Mismatch between capacity and application: Small-capacity products (e.g., 10ml serums bottles) may have excessively large packaging, while large-capacity lotion bottles may be t...

When choosing skincare product packaging, the key differences between UV-protective glass bottles and ordinary glass bottles are mainly reflected in the following aspects: In terms of protection, UV-protective glass bottles can block more than 99.5% of ultraviolet rays (380-500nm band), effectively protecting photosensitive ingredients such as vitamin C and retinol from photo-oxidation; while ordinary glass bottles have almost no professional ultraviolet protection capabilities (blocking rate <50%). In terms of product lifespan and cost, UV-resistant glass bottles can extend product shelf life by 40%-60%, but due to the addition of special oxides, the material cost is 15%-25% higher than that of ordinary glass bottles. In terms of sustainability, both types of glass bottles are 100% recyclable, but the UV-resistant glass bottle can be combined with PCR recycled materials, making it more environmentally friendly. 1.UV Blocking Mechanism:  UV-protective glass bottles form a stabl...
