Glow's full ranking.
Hyaluronic acid is the most miscategorised molecule in skincare. Used wrong, it draws water out of your skin in dry climates. Used right, it's the cheapest plumping ingredient on the shelf.

Hyaluronic Acid Mist
Best for on-the-go reapplication
Premium Australian brand's spray-format HA. Useful for plane travel and dry-air offices. Won't replace a serum but earns its keep as a top-up.
Frequently asked
Common questions.
Should I apply HA to wet or dry skin?
Damp. Hyaluronic acid is humectant — it binds water from whatever's nearest. On dry skin in low humidity, it can pull water from your dermis. Apply to damp skin and seal with moisturiser.
How often can I use HA?
Twice daily, indefinitely. Unlike retinoids and acids, HA has no irritation ceiling. Many testers used it as the consistent baseline through 12-week reactive-skin recovery.
Is hyaluronic acid the same as sodium hyaluronate?
Technically no — sodium hyaluronate is the salt form, with smaller molecules and better penetration. Most products use both. The stack is what matters.
Can HA cause breakouts?
Rarely on the molecule itself. Breakouts usually trace to other actives in the formula or to occlusive layers trapping pre-existing comedones. Patch test if you're acne-prone.
