No.9 NAD+ BIO Lifting-sil Essence — Reddit Reviews
by numbuzin
Updated October 29, 2026
Peptide-rich essence delivers cushiony hydration and glow; anti-aging results stay modest.
What the community says
A peptide-heavy essence with glycerin, niacinamide, shea butter, and sodium hyaluronate, it behaves more like a thin lotion than a watery serum. Dry, tret-treated skin gets glow and cushion; oily or acne-prone users may find it greasy or breakout-inducing.
What this means for you
What people love
Watch out for
