Loved & recommended
Hyaluronic acid is simple and it works, provided you use it right — onto damp skin, sealed with a moisturiser, so it doesn’t pull water out in dry air. Done that way it is the most reliable plumping step for tight, dehydrated skin, and it suits everyone.

The science behind the formula
Hyaluronic acid draws water into the skin's surface layers. It works best applied to slightly damp skin and sealed with a moisturiser, so the water it attracts stays in the skin rather than evaporating.
FAQs
When do I apply it?
To slightly damp skin after cleansing, then seal with a moisturiser to hold the water in.
Is it OK for oily skin?
Yes — it is water-light and oil-free, so it hydrates without heaviness.
Can I use it morning and night?
Yes, twice daily.
Can I use it with retinol or vitamin C?
Yes — hyaluronic acid layers well with almost anything and helps buffer stronger actives.
Why does my skin feel tight sometimes after using it?
In very dry air, apply it to damp skin and always seal with a moisturiser, so it draws water into the skin rather than out of it.
How much should I use?
Two to three drops pressed over the face and neck.
Is it suitable for sensitive skin?
Yes — it is gentle and suits all skin types, including sensitive.
How long will one bottle last?
At twice-daily use one bottle typically lasts around two months.
Is it safe to use during pregnancy?
If you are pregnant or breastfeeding, we recommend checking with your doctor before starting any new active skincare.
How is it shipped, and can I return it?
