Cons

  • Can pill when layered over certain serums or heavier textures — application order matters

Pros

  • 10% niacinamide is a clinically validated concentration for sebum regulation, pore appearance, and mild brightening
  • Fragrance-free and well tolerated — no irritation reported even in sensitive or reactive skin users
  • Lightweight, fast-absorbing formula layers easily under moisturiser and makeup
  • 1% hyaluronic acid (sodium hyaluronate) supports hydration without greasiness

Cons

  • Carbomer-heavy gel base can leave a white cast and pilling sensation if more than a pea-sized amount is used
  • Mild tackiness noted immediately post-application, especially with heavier-handed application
  • Tube packaging makes precise dosing difficult and can dispense excess product
  • Photosensitivity anecdotally reported by one reviewer when used in the morning — general sun protection advice applies
