Hyaluronic Acid
A polysaccharide naturally found in the dermal matrix; topically it draws water to the skin's surface and plumps fine dehydration lines.
Hydrophilic glycosaminoglycan that binds up to 1,000× its weight in water, hydrating the stratum corneum without occlusion.
- Hydrates
- Plumps fine lines
- Soothes
- Supports barrier
- Universally tolerated
What the evidence supports.
- All skin types
No notable contraindications reported.
Mid-routine serum or treatment step.
Concentration range in well-formulated products: 0.1%–2%
Year-round; in dry climates always seal with emollient to prevent reverse-osmosis dehydration.
Bone broth, soy, root vegetables support endogenous HA synthesis.
- Dehydration lines
- Tight feeling skin
Always apply to damp skin and immediately follow with a moisturiser. Dry-on-dry application can backfire.
