What the AI looks for in Refillable Cosmetic Droppers
- Glass color
- Amber or cobalt glass for light-sensitive oils and serums UV light degrades vitamin C, retinoids and essential oils.
- Bulb material
- Silicone or nitrile bulb rather than cheap natural rubber Rubber bulbs swell, crack and taint contents when exposed to essential oils.
- Pipette fit
- Pipette length reaches near the bottom of the bottle, and the cap seats with a liner Short pipettes leave product stranded, and loose caps leak or evaporate.
- Neck finish
- Standard thread size, such as 18-400 or 20-400, matching the dropper caps Standard necks let you swap droppers, orifice reducers or roller tops on the same bottle.
What to avoid
- Clear plastic droppers for essential oils or actives
- Sets with no spare pipettes or bulbs
- Droppers for thick serums that will not draw up
