Ascorbyl Glucoside is a glycosylated stable Vitamin C derivative that is converted to free L-ascorbic acid in viable human epidermis1. In a 24-week double-blind half-face study (n=27), an ascorbyl glucoside complex significantly reduced the appearance of pigmentation on solar lentigos compared to placebo. That study used a 28% complexed concentration, while this formulation uses 2% ascorbyl glucoside2. Ferulic Acid contributes to the canonical Vitamin C antioxidant network. Ferulic acid has been shown to stabilise a topical vitamin C and E solution and double its photoprotection, an effect cited as mechanism-class plausibility because it has not been directly tested for the ascorbyl glucoside form3. Multi-weight Hyaluronic Acid pairs surface and penetrating molecular weights for hydration4.

SCIENCE, MADE VISIBLE
Opuliss begins where the research ends. Every active is named, every claim is traceable, and nothing is left to promise alone.
Morning to night
A RITUAL, CONSIDERED
Each formula stands on its own and belongs to the whole. Layered with intention, morning and night, the routine becomes unmistakably yours.
A twenty four hour rhythm
THE SKIN KEEPS TIME
Skin is not the same at midnight as it is at nine in the morning. Across a single day its temperature, its acidity and the moisture it loses to the air each move on a rhythm of their own. Morning and night are not two routines. They are one, kept in time.
