What it does
- Draws water into the outer skin layers
- Makes skin look plumper and reflect light more evenly
- Softens the appearance of fine lines temporarily
- Improves comfort in dry or dehydrated skin
The mistake almost everyone makes
Applied to dry skin in a dry environment, a humectant can pull water from deeper layers and leave skin feeling tighter than before.
Apply it to damp skin and seal it with a moisturiser. That single change is the difference between it working and it backfiring.
Molecular weight, briefly
High-molecular-weight HA sits on the surface and holds water there. Lower-weight fragments penetrate slightly further. Many products blend both, which is a reasonable approach and not worth agonising over.
What it doesn't do
Topical hyaluronic acid doesn't add structural volume, doesn't tighten skin and isn't comparable to an injectable. It's a surface hydrator with a same-day cosmetic effect.
How to use it
- Apply to damp skin, morning and night
- Always follow with a moisturiser
- Pairs well with everything, including retinoids and vitamin C
- In very dry air, prioritise the occlusive layer over the humectant
