Case Study: How Glass Lotion Bottles Helped a Japanese Brand Fix Quality

See how custom glass lotion bottles helped a Japanese skincare brand improve pump performance, bottle stability, and premium packaging, driving sales growth.

Client Background

A Japanese skin-care brand that specializes in gentle, hydrating lotions (for sensitive and dry skin) wanted to upgrade its packaging. Specifically, they wanted custom glass lotion bottles: clear glass 120ml and 180ml WITH a slim curved shape, with a (press pump), WITH a simple silver foil logo. They chose Vesseluxe to align with their “minimalist luxury” ethos, as they needed glass lotion bottles that felt premium yet easy to use.

Our challenges

Prototypes had key issues: the press pump often jammed, failing to dispense lotion evenly; the curved bottle’s surface made the silver foil logo peel off easily; and the bottle’s thin base tipped over frequently, causing spills. These flaws risked ruining the brand’s focus on “seamless user experience.”

Root Cause Analysis

Our team found: the pump jammed because its internal tube was too narrow for the lotion’s light viscosity; the logo peeled due to uneven adhesive on the curved glass; the tipping stemmed from a 4cm-wide base (too small for the 16cm-tall bottle’s weight distribution).

Our solution

To fix the pump, we widened the internal tube by 0.3mm and tested 30 pcs samples for smooth dispensing. For the logo, we used a flexible, curved-adapted foil and added a UV-cured layer for adhesion. We expanded the base to 6cm, keeping the slim look while boosting stability.

The client launched successfully in Japan, receiving praise for packaging innovation. Sales increased by 35% within three months, attributed partly to the premium unboxing experience. Vesseluxe’s rapid prototyping and reliability and timely delivery ensured they were on the market on time. This partnership also developed the brand’s identity, while raising the luxury skincare packaging standard in Asia.
