Transparency lies at the heart of our philosophy which is why we have partnered with tech-platform – Provenance – to cut through the industry ‘noise’ and equip you with key facts that matter. A 'proof point' with a green tick means a third party has verified the accuracy of the statement whereas no green tick means that there isn't independent confirmation (yet!), but that the brand has still supplied substantiating evidence (which you can view yourself).

Great moisturising Vitamin C!
I started using this serum just over a year ago and I’m already on my third bottle! I've always struggled with hyperpigmentation, and I think the formula has worked really well to improve it! I use it most mornings before applying my sunscreen and I find it really moisturising. Definitely one of my favourite skincare treats - the only downside is the price!
