A topical serum acts where you apply it. Formulated properly, it does real work: hydration, barrier support, resurfacing, and delivery of actives to the upper layers. Ours are built to do exactly that, at concentrations that matter.
But the barrier that makes skin a good protective organ also makes it a selective one. Molecular size, polarity and charge determine what crosses and what does not. Collagen does not cross. It never will, whatever the packaging says.
And most of what presents at the surface did not start there. Dermal collagen is synthesised by fibroblasts that depend on adequate vitamin C, amino acids and antioxidant status. What shows on the skin is frequently downstream of systemic oxidative load, gut barrier function or hormonal change.
If the driver sits below the surface, the support has to reach below the surface too.
So every system pairs a topical with an oral formulation targeting the same concern. Same target, two routes, chosen according to which route can actually reach it.
That is what COMPLETE means.
Independently conducted over 12 weeks. Individual results vary.
*Based on independent 12-week trials across 93 participants. Individual results vary.
This is not an overnight fix. Genuine improvement develops progressively, with consistent daily use.
Comfort and hydration come first. Skin feels calmer and more balanced, and texture begins to smooth. This is the phase most people underestimate and most brands overpromise.
Visible change begins, depending on your system. Clarity, brightness or firmness. Hair and nails may start to feel stronger on Radiance.
The deeper results arrive. On Clarify, 83% reported significantly clearer skin by week 12 (n=30). On Protect, 77% reported firmer skin and visibly reduced fine lines (n=31). On Radiance, 81% reported healthy radiance (n=32).
We've got the answers.
Most brands formulate a serum and a supplement separately, then sell them alongside one another. We start with a concern, work out which parts of it can be reached at the surface and which cannot, then build both halves to address the same target. The pairing is the product.
Our evidence sits at two levels.
At finished-product level, all three systems went through independent twelve-week consumer studies conducted by a third-party research organisation, using the products exactly as you receive them, in participants' own homes and routines. Ninety-three people took part: thirty on Clarify, thirty-one on Protect and thirty-two on Radiance. Responses were recorded at first use and at four, eight and twelve weeks. No adverse reactions were reported.
At ingredient level, every active is grounded in clinical research and chosen on trial data. Dr SCS reviewed thousands of data points from published trials before deciding what went into each formulation and at what concentration. That includes two placebo-controlled human studies on the vegan collagen in our Dual Collagen Complex.
All three serums have also been through 96-hour human patch testing under dermatological control, alongside independent safety assessment, stability, microbiological, pH and packaging compatibility testing. The laboratory conducting our studies is accredited to ISO 9001:2015 and ISO 17025:2017, and all work was carried out in accordance with Good Clinical Research Practice and the Declaration of Helsinki.
The outermost layer of skin exists to keep things out, and it is very good at its job. That is a benefit for daily life and a limitation for skincare, because it constrains how much of any active can reach the living tissue below. Dr SCS
spent her doctoral research on precisely this question.
A supplement bypasses the barrier entirely, arriving through the bloodstream at the tissue where collagen is synthesised and where cellular change begins. Working both routes at once is how you reach the whole of a concern rather than the part of it you can see.
The gut and skin communicate constantly, through immune signalling, inflammatory pathways and the microbiome. It is why digestive changes so often show on the face. Our own study data reflects it: at twelve weeks, 83% of Clarify participants reported bloating significantly reduced or resolved alongside their skin results, and 80% reported improved digestive health overall.
