Why We Made It

Skin does not need persuading. It needs company.

The Formula

Three actives. Not One For Show.

A vitamin C serum built for one job: bringing back brightness and evening out tone, morning and night.

01Vitamin C

Brightens, Day And Night

Lifts dullness and helps defend skin against the day’s oxidative stress.

02Hyaluronic Acid

Hydrates, Plump And Dewy

Holds water in the skin so brightening never comes at the cost of comfort.

03Panthenol

Soothes, Quietly

Supports the skin barrier while the vitamin C does the brightening.

The Ritual

One minute, Morning And Night.

Step One

After Energy Drench

One pump, on cleansed skin, once your essence has absorbed.

Step Two

Press, don’t rub

Work outward from the centre of the face. Let it absorb fully.

Step Three

Then Golden Hour, then Collagen Reform

Using acids or retinol? Apply Brilliant C first and let it absorb before anything else.

Why It Works

Three decisions We Made On Purpose.

Made for one job, not every job.

Brilliant C is for dullness, dark spots and uneven tone. It suits all skin types, acne-prone included.

Vitamin C, paired, not alone.

Hyaluronic acid and panthenol work alongside it, so brightening comes with hydration and comfort, not just strength.

Chosen for skin in recovery.

Highly recommended alongside microdermabrasion, chemical peels and laser treatments.
