    The serum together with the Pestle & Mortar light moisturiser has made a huge difference to my skin. It's helped ease the tightness & irritation I suffered from post menopause. I do use them in conjunction with other moisturisers & SPF. Great find for me.

    Great product in my beauty repertoire I use it in in conjunction with the light moisturiser in the range. But I do need to use additional moisturisers with my sometimes tight & angry ski.n. Great product in my view

    Elegant formula that really works

    A really elegant hydrating serum that does exactly what it promises. My skin feels quenched, looks brighter, and has that healthy bounce I’m always looking for.

    Gives such a lovely plumping effect

    This gives such a lovely plumped effect. My skin feels soft, smooth, and more elastic, especially in the morning after using it the night before.

Smaller molecules penetrate deeply to replenish moisture and support barrier repair, while larger molecules form a breathable moisture barrier on the skin’s surface, preventing dehydration. Enriched with soothing cucumber extract and aloe, this iconic serum hydrates without heaviness to leave skin smooth, plump, and supple.

  • Hydrates
  • Firms and plumps
  • Strengthens the skin barrier
