Frequently asked questions

What does hyaluronic acid do?
It's a humectant that draws water into the skin for plump, bouncy hydration. Seal it with a moisturizer so it doesn't evaporate in dry air.
When do you apply hyaluronic acid?
On damp skin after toner, before moisturizer, so it has water to bind and you can lock it in.
