Frequently Asked Questions

Shop With Peace of Mind

Clear answers to the most common questions so you can check out with confidence.

1) How long does one bottle last?

It depends on how often you use it. Most customers find one bottle lasts around 2–4 weeks with regular daily use. If you’re applying more frequently or covering a larger area, it may run out sooner — that’s why bundles are the best value.

2) What age is it suitable for?

Natural Flexi Gel is designed for adults. If you’re pregnant, breastfeeding, taking medication, or have a medical condition, it’s best to check with a healthcare professional before use.

3) Does it smell strong or feel greasy?

No — it’s made to be lightweight and quick-absorbing. Most people describe the scent as mild and the finish as non-greasy, so you can apply it and get on with your day.

4) Can I use it on sensitive skin?

If you have sensitive skin, we recommend a simple patch test first: apply a small amount to a small area and wait 24 hours. Do not apply to broken, irritated, or inflamed skin. Stop use if irritation occurs.

5) How do I use it and how often?

Roll a small amount onto the area around the knee and gently massage for 10–15 seconds. Use 2–3 times daily as needed. Always wash hands after use (unless you’ve used only the roll-on and haven’t touched the gel).

6) How long does UK delivery take — and will I get tracking?

UK delivery typically takes 2–5 working days (depending on your location and demand). You’ll receive a tracking link once your order has been dispatched.

7) What is your returns policy?

You’re covered by our 30-day returns policy. If you change your mind, contact us within 30 days of receiving your order and we’ll guide you through the process. Items must be unused and in original packaging (unless faulty).

8) What’s the difference between the bundles?

Bundles give you more value per bottle and reduce the chance of running out.

  • Buy 1: best to try it first
