How long does a 30 ml tube typically last with daily use?

The recommended amount is a small dab — roughly the size of a rice grain — for each eye, applied morning and evening. That's approximately 0.05–0.07 ml per application total, or 0.1–0.14 ml per day. At that rate, a 30 ml tube provides roughly 215–300 applications, which translates to 3.5–5 months of twice-daily use. Factors that shorten lifespan: using more than needed (the skin can only absorb so much; excess just sits on the surface), applying to the entire orbital bone rather than just the crow's-feet and under-eye zone, or sharing the product. Factors that extend it: using only in the evening, or alternating with a lighter gel in summer. The tube format helps dispense small, controlled amounts and limits air exposure, which preserves the hemp seed oil's oxidative stability — important because unsaturated oils can degrade over time once opened. For reference, most eye creams on the market range 15–30 ml; 30 ml is on the generous side for this category.
