How much hyaluronic acid does your serum contain?
The percentage of hyaluronic acid (HA) solution present in Pestle & Mortar Pure Hyaluronic Serum is 80% which is 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.
