What's inside

Key ingredients, plainly stated.

Full breakdown ↓
01

Ascorbic acid (Vitamin C)

Sealed into single-use capsules at full potency, so it never sits oxidising in a bottle. 15% is within the range shown to help visible brightening without the irritation more aggressive percentages can cause.

02

Ferulic acid

Stabilises vitamin C and adds its own antioxidant support — the classic, well-studied pairing.

03

Vitamin E (tocopherol)

Rounds out the antioxidant trio with vitamin C and ferulic acid. Also helps the oil phase of the capsule feel less drying.

04

Squalane

Carries the actives and keeps a high-percentage vitamin C formula from feeling harsh.

How to use

Crack, apply, done.

Morning only — vitamin C works best under SPF, not instead of it. Twist and snap one capsule, use the full dose immediately; there’s no lid to reseal because there’s nothing left to protect from air.

01

Cleanse & dry

Vitamin C at this concentration goes on fully dry skin, unlike the rest of the line.

02

Snap one capsule

Twist to break the seal and massage the full dose across face and neck. Use it all — there’s no saving half a capsule.

03

SPF, non-negotiable

Vitamin C pairs with sunscreen, it doesn’t replace it. Apply SPF as the last step, every morning you use this.
