Where Rejuvea's actives are measured, validated and proven under controlled conditions.

Clinical Evidence

Backed by
Research.

University of Pavia UB Care

Laboratory evaluations conducted in collaboration with the University of Pavia and UB Care assessed Rejuvea's multi-molecular hyaluronic acid complex under controlled conditions.

The findings demonstrated a significant reduction in the expression of the pro-inflammatory marker IL-8, supporting the formula's soothing and skin-supportive properties.

Formulation Specification

Clearly Defined
Molecular Weights.

High MW 1800kDa
Surface Layer

Forms an intelligent moisture film at the skin's surface — delivering immediate visible plumping, barrier protection, and prevention of transepidermal water loss.

Medium MW 400–600kDa
Epidermal Layer

Penetrates the upper epidermis to reinforce the moisture reservoir at the cellular level, progressively improving elasticity, resilience, and uniform hydration.

Low MW 50kDa
Dermal Layer

The smallest, most potent fragment — travels deepest to bind water where volume is lost and activate the skin's innate repair and regeneration signalling pathways.
