The efficacy score is driven almost entirely by retinal listed as the key active near the top-middle of a short INCI, suggesting a meaningful concentration in line with the 1% claim, supported by good humectants (glycerin, sodium hyaluronate, pentylene glycol) and soothing botanicals rather than barrier lipids or rich emollients, which means strong anti-aging and texture-smoothing potential but a higher risk of dryness or irritation if not buffered by a robust moisturizer.

EXTERNAL CITATIONS
Retinal: Retinaldehyde is an oxidized retinoid shown to improve photoaging, wrinkles, and epidermal thickness with better tolerability than retinoic acid in several clinical and in vivo studies; typical effective ranges are around 0.05–0.1% in cosmetic formulations.
Sodium Hyaluronate: Topical sodium hyaluronate acts as a humectant, improving skin hydration and elasticity, with multiple studies demonstrating increased moisture content and reduced transepidermal water loss.
Glycerin: Glycerin is a well-established humectant that increases stratum corneum hydration, supports barrier function, and improves skin mechanical properties in controlled clinical studies.
