Short answer: a 180-day window gives ample time to judge gradual, cumulative results fairly — meaningfully longer than the 30-60 day windows common elsewhere in this category, though terms should still be confirmed before ordering.
Why 180 days is a genuinely generous window
Many users report changes building over four to eight weeks of consistent use — a 180-day guarantee provides several months beyond that for a fair, unhurried evaluation.
What to verify before relying on the guarantee
- Whether the window is measured from purchase date or delivery date
- The exact, current process for requesting a refund
- Whether return shipping is your responsibility
💡 The honest standard: refund terms can change over time — always confirm the current policy on the official order page before buying, rather than relying solely on a review site's description.
Why a long guarantee window is a meaningful signal
Offering an extended evaluation period is consistent with a brand expecting gradual, not instant, results — a structural signal worth noting alongside the ingredient science itself.
