Antioxidant
Phloretin

A dihydrochalcone polyphenol (aglycone of phloridzin) extracted from apple (Malus domestica) bark, roots, and leaves. Neutralizes free radicals via hydrogen-atom transfer and single-electron transfer mechanisms; inhibits tyrosinase (mixed-type, IC50 169 µM) to reduce melanin precursors for brightening; and suppresses NF-κB via direct TLR2 binding for anti-inflammatory benefit. Clinically studied at 2% in combination with L-ascorbic acid and ferulic acid — this triple combination significantly reduced UV-induced markers (MMP-9, thymine dimers, p53) in a peer-reviewed trial (Oresajo et al. 2008). The active ingredient in SkinCeuticals Phloretin CF.

Humectant
Phormium Tenax Extract

Extract from Phormium tenax (New Zealand flax / harakeke), a monocot in the Xanthorrhoeaceae family unrelated to common flax (Linum usitatissimum), with traditional Māori use in wound and skin care. Primary bioactive fractions are polysaccharides rich in D-xylose and D-glucuronic acid alongside linoleic acid, which contributes to ceramide biosynthesis and barrier integrity. The hero ingredient in The Saem Urban Eco Harakeke product line.
