HydraPlump System

A multi-weight hyaluronic acid serum that locks in deep, long-lasting hydration to quench thirsty skin, smooth fine lines, and restore bounce.

Skin concerns

  • Dehydrated skin
  • Dry skin
  • Ageing and fine lines
  • Loss of elasticity

Why it works

This lightweight serum delivers multi-layer hydration using a blend of high and low molecular weight hyaluronic acid. 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.

How to use
  • Use 2-4 drops morning and night after cleansing.

  • Use as a serum AM and PM, as a makeup primer, or to top up hydration throughout the day.

FAQs

How much hyaluronic acid does your serum contain?

The percentage of hyaluronic acid (HA) solution in Pestle & Mortar Pure Hyaluronic Serum is 80%, which equates to a 2% concentrate.

What age is the Pure Hyaluronic Serum for?

Pure Hyaluronic Serum can be used across all age groups. With time, hyaluronic acid in your body decreases, leading to dry ageing skin and wrinkles among many other things.

That is why it is so important to include hyaluronic acid in your skincare routine. The younger you start including hyaluronic acid the better.

My hyaluronic serum seems to be drying my skin.

Some people find that in extreme low humidity, the operation of humectants is reversed – i.e. they draw water from the deeper layers of the skin because there is none in the air. For this reason, we recommend that the most effective use of Pure Hyaluronic Serum is always to layer it with a moisturiser, as this will seal the hyaluronic acid into the skin and will also provide the skin with a barrier against moisture loss. Also, apply your serum to damp skin, not completely dry skin. If you find that in very dry weather your serum is not performing, use a heavier or more occlusive moisturiser or face oil.

Can I use Pure Hyaluronic Serum with other acids in my routine?

Yes. You can layer hyaluronic acid with everything that you are currently using in your skincare routine. Pure Hyaluronic Serum is ph 7, neutral and will not interfere with other ingredients in your routine.

Will my products that are in glass be okay without the outer cylinder?

Yes. We wrap all glass products in 100% recycled paper to ensure they remain safe and secure.

    Love this product !

    Have been using it over a year, have tried others but this is my favourite. Skin is soft, smooth & wrinkle free. Not bad for a 54 year old !

    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

    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.

    Hydrating without feeling greasy

    I have combination skin and was worried this might feel too rich, but it’s actually perfect. Super hydrating, non-greasy, and leaves my skin feeling really balanced.
