The ingredients your skin actually needs

Three actives show up in almost every evidence-backed formula. They earn that attention.

Niacinamide: the even-it-out active

Niacinamide (vitamin B3) reduces melanin transfer between skin cells. That means fewer dark spots, less redness, and a more uniform finish over consistent use. Concentrations between 2% and 10% are where the research sits. Below 2%, you're paying for a label claim.

Pair it with zinc PCA for oil control. The two work on different sebum pathways, and together they outperform either ingredient alone for textured or congested skin.

Our Brightening Serum No. 1 runs at 4% niacinamide and 1% zinc PCA. That's inside the evidence window, enough for visible tone-evening without the irritation risk of higher doses.

Hyaluronic acid: not a moisturiser, exactly

Hyaluronic acid (HA) is a humectant. It pulls water from the environment and holds it at the skin surface. It doesn't oil-proof your skin or repair your barrier. It fills and plumps where water is missing.

Molecular weight matters more than the percentage on the label. Low-molecular-weight HA penetrates deeper layers. High-molecular-weight HA works at the surface. A formula with both is more complete.

HA works best when your barrier is intact. On stripped or reactive skin, it can pull moisture upward and actually increase water loss. That's why HA and ceramides belong in the same routine. Our Barrier Repair Serum pairs them together: ceramide NP and cholesterol lock in what the HA draws in.

Vitamin C: the clarifier

L-ascorbic acid inhibits tyrosinase, the enzyme that triggers pigmentation. It also neutralises free radicals from UV and pollution, which slows collagen degradation over time.

The catch is stability. L-ascorbic acid oxidises quickly in water. At room temperature in a clear bottle, it goes from clear to orange to brown, losing potency as it goes. If your vitamin C serum is already amber when you open it, it's working less.

Derivatives like ascorbyl glucoside are more stable and gentler. For sensitive skin, a derivative is a reasonable first vitamin C.

Use it in the morning before SPF. Niacinamide and vitamin C coexist fine in the same routine. The flushing concern is largely debunked at modern formulation pH levels.

The takeaway

These three actives share most evidence-backed routines for a reason. They work on complementary pathways: tone, hydration, and oxidative protection. The formula earns its price when the concentrations are honest and the supporting cast is right.

Start with one. Give it three weeks.
