Serum 01 — Retinaldehyde

0.05% retinaldehyde, encapsulated, pH 5.5.

A nightly retinoid for cumulative collagen renewal. Retinaldehyde converts to retinoic acid in a single enzymatic step, delivering measurable results with markedly less irritation than retinol at equivalent strength. Formulated with a low-friction emulsion of squalane and bisabolol so the active reaches the dermis without disrupting the barrier.

In a 12-week open-label study (n=42, IRB-approved, Lisbon 2022), participants showed a 28% reduction in periorbital line depth and a 41% reduction in self-reported irritation versus 0.3% retinol.
