12-Week Money-Back Guarantee


We’re so confident in our 12-Week Stretch Mark Programme that we offer a money-back guarantee.

Our programme has been specifically designed to support visible improvements in the appearance of stretch marks over time. While some customers begin to notice changes within the first few weeks, the most significant improvements typically occur after 12 weeks of consistent use. In our customer trial, those who completed the full 12-week programme were 78% more likely to report significant visible improvements than those who stopped earlier.

Our biggest tip? Stay consistent. Visible skin remodelling takes time, and using the programme exactly as directed gives you the best chance of achieving results.

To qualify for our money-back guarantee, you’ll need to meet the following criteria:

  • Take clear, well-lit photos of your stretch marks before beginning the programme. Your photos must include a visible date and time stamp.
  • Complete the full 12-week programme as directed. The programme is designed to be completed over three monthly purchases. However, as product usage varies between individuals, we will also honour the guarantee where a minimum of two programme purchases have been used as directed over the full 12 weeks. This includes:
    • Applying the Stretch Mark Cream twice daily.
    • Using the Stretch Mark Serum and Microneedling Tool once per week, following the instructions provided.
  • At the end of the 12 weeks, take a new set of photos in similar lighting, from the same angle and distance as your original photos. These must also include a visible date and time stamp.
  • Email your before and after photos, together with your order number, to hello@strialab.co.uk. Our team will review your submission within 24–48 hours.
  • If your claim is approved, we’ll issue a full refund, less a £5 (UK) / $10 (AU) deduction per shipment to cover shipping and handling costs.

The guarantee is only valid where the programme has been used consistently and according to our instructions for the full 12-week period.
