The 90-day results guarantee
Take Collagen Core every day for 90 days. If you don't see a visible improvement, we'll refund the product in full.
This is a results guarantee, not a change-of-mind return. It asks you to actually complete the protocol, and it asks you to be able to show that you did. Every condition is set out below. Read them before you order — one of them starts on day one.
Start your daily photo record on day one
The guarantee requires a dated daily photo record of your use. If you don't start it on the day your first tub arrives, you cannot claim later — there is no way to reconstruct it afterwards.
Each day, before you drink it, photograph your prepared serving with that day's date clearly visible in the same frame — your phone's lock screen showing the date is the easiest way, or a handwritten date card next to the glass.
We accept a record covering at least 84 of the 90 days. Six missed days is the allowance; more than that is not a completed protocol.
Who it applies to
- 3-tub and 6-tub orders only. The guarantee is built on a 90-day protocol. One tub is 28 days, so a single-tub order cannot demonstrate one and is not eligible — it is covered by the standard 30-day return below.
- Your first order of Collagen Core. Once you have claimed, you have claimed.
- One claim per person, household, shipping address and payment method, ever. Claims linked by any of those are treated as the same claim.
- Bought directly from kollaris.com. We can't verify anything bought elsewhere.
When to claim
Between day 90 and day 120 from your order date. Not before — you haven't finished the protocol. Not after — the window has closed.
What we need from you
Email supportkollaris@gmail.com with:
- Your order number.
- Your daily photo record — a link to a shared album or folder covering at least 84 of the 90 days, each photo showing the prepared serving with that day's date visible.
- A photo of each tub you used, showing it empty, with the batch code on the base legible. Three tubs, three photos.
- A short note on how you took it — time of day, what you mixed it with, and which days you missed.
These are the conditions of the offer, not a formality. A claim missing any of them cannot be assessed and will not be approved. We may ask follow-up questions, and we may decline a claim where the record does not support daily use across the full period.
Keep your tubs and your photos until your claim is settled. Don't throw either out on day 89.
Unopened tubs come back
Any tub still sealed must be returned before we issue the refund, at your cost, to the address we give you. We refund once it arrives. The guarantee covers a protocol you completed, not stock you didn't open.
What you get back
The product price you paid, to the original payment method. Return postage is yours. Refunds are issued within 5 business days of approval; your bank usually takes a further 5–10 days to post it.
Standard returns
Changed your mind? Return any unopened, unused, undamaged tub within 30 days of delivery for a refund of the product price. No photo record needed — this route is for product you never started. Email us first for a return address; parcels sent back without contacting us cannot be traced to your order and cannot be refunded. Return postage is yours unless the return is our error.
Opened tubs are not eligible for a standard return. Supplements are consumable and we cannot resell them.
Damaged, wrong, or missing items
Email us within 14 days of delivery with your order number and a photo of the item and the packaging. We'll replace it or refund it, your choice. No return needed, and no photo record needed.
Subscription orders
Cancel before your next renewal and you won't be charged again — see our Subscription Policy. An order that has already shipped is covered by the terms on this page.
Claims we decline
- Anything outside the windows above.
- Claims without a daily photo record covering at least 84 of the 90 days.
- Records where the dates cannot be read, are duplicated, or were plainly taken on fewer days than claimed.
- Claims without the empty-tub photos and the usage note.
- Second and subsequent guarantee claims from the same person, household, address or payment method.
- Orders showing a pattern of resale, or unusual volume.
- Products not bought from kollaris.com.
We reserve the right to refuse a refund where we reasonably believe the guarantee is being abused, and to decline future orders from that customer. Nothing on this page limits rights you have under law that cannot be limited by contract.
Talk to us before your bank
If something is wrong, email us — we answer within 1–2 business days, and we'd rather fix it. A chargeback raised without contacting us first will be contested with the order, delivery and correspondence records, and it ends any guarantee claim on that order.
