What people love

  • High beta glucan concentration delivers deeper hydration than typical HA serums
  • Lightweight texture layers well under makeup and moisturizer for a non-greasy feel
  • Popular go-to for barrier repair and calming irritation, especially alongside tretinoin

Watch out for

  • Recent formula changes reportedly reduced hydration and introduced a faint, unexpected fragrance
  • Can cause breakouts or burning/redness in sensitive, acne-prone, or rosacea-affected skin
  • May increase tretinoin penetration causing flaking and irritation if not layered properly
