Radiance Vitamin C Serum
15% stabilised vitamin C to brighten, even tone, and restore morning glow.
We believe in doing less, beautifully. Each KingdomPK formula is built around a single, clinically inspired hero active, small-batch blended and finished by hand in the United States.
No overloaded formulas. No filler actives. Just one purposeful hero ingredient per bottle, at a concentration that actually performs.
One hero active per formula, dosed to a meaningful concentration, so your skin gets exactly what it needs and nothing it does not.
Fragrance-optional emulsions and serums built on ceramides, hyaluronic acid, and skin-identical lipids. Gentle enough for daily use.
Every batch is stability tested and pH verified. We hold documentation on each run, the same standard our lab partners expect.
Never tested on animals. Transparent labels. What is on the box is what is in the bottle, at the concentration we state.
A tightly edited range of hero formulas, loved for results you can see and a finish that feels like luxury.

15% stabilised vitamin C to brighten, even tone, and restore morning glow.

Encapsulated retinal in a ceramide-rich base to smooth and refine overnight.

Multi-weight hyaluronic acid for deep, cushioned, all-day hydration.

Balances shine, refines pores, and comforts reactive, blemish-prone skin.
KingdomPK began with a simple frustration: skincare shelves crowded with 20-ingredient promises that under-deliver. We took the opposite path.
Start with clean, dry skin. Our gentle bases layer beautifully over your existing cleanser.
Apply your chosen hero serum. One active, dosed properly, is all your skin needs at a time.
Lock it in with a nourishing moisturiser and SPF by day. Consistency is the secret.

"Finally a retinal that my sensitive skin tolerates. Smooth, calm, and no peeling. Obsessed."
"You can tell these are made in small batches. They feel fresh, luxurious, and they actually work."
