Key ingredients

Niacinamide

Strengthens the barrier, controls oil, and fades dark spots — gentle and plays well with almost everything.

Hyaluronic Acid

Holds water in the skin for instant plumping and hydration.

Ceramides

Barrier lipids that seal in moisture and repair a compromised skin barrier.

Peptides

Amino-acid messengers that signal collagen production for firmer, smoother skin.

Squalane

A lightweight, biomimetic oil that softens without clogging pores — pairs perfectly with strong actives to offset dryness.

Vitamin E

An antioxidant that protects the barrier and supercharges vitamin C.

Gluconolactone (PHA)

A gentle, large-molecule exfoliant that smooths and hydrates — ideal for sensitive skin.

Zinc PCA

Controls oil and calms blemish-prone skin.

Glycerin

The workhorse humectant — simple, effective, and exceptionally well-tolerated.
