Protective Base Prep

A hydrating primer that helps foundation sit smoothly and grip more evenly. The serum-like texture leaves a comfortable, luminous layer for makeup without a heavy primer feel.

  • Helps makeup adhere evenly for a smoother-looking base.
  • Adds lightweight moisture so foundation is less likely to emphasise dry texture.
  • Niacinamide, betaine and glycerin support hydrated, radiant-looking skin; ceramide, squalane and botanical ferments add conditioning care.

Hydration, grip & a smoother base
