What is Hyaluronic Acid?
A humectant that holds 1000x its weight in water. Naturally present in skin, joints, and eyes. Provides intense hydration without heaviness. Safe for all skin types.
✅Key Benefits
- ✓Holds 1000x its weight in water
- ✓Provides deep hydration
- ✓Plumps fine lines temporarily
- ✓Improves skin elasticity
- ✓Lightweight, non-comedogenic
- ✓Reduces TEWL
- ✓Compatible with all actives
🎯Best For
All skin typesDehydrated skinFine linesSensitive skinPost-procedure
📋How to Use
Apply to DAMP skin (crucial!), then layer moisturizer on top. Can use AM and PM. Safe to use with all actives. Multiple molecular weights work at different skin depths.
⚗️RECOMMENDED CONCENTRATION: 0.1-2% (effective range)
⚠️Avoid Mixing With
- ✕None - universally compatible
💚Pairs Well With
- ✓Everything - retinoids, vitamin C, niacinamide, acids, peptides
🚫Avoid If
- ⚠Dry climates without occlusive moisturizer (can dehydrate)
- ⚠Never on bone-dry skin
🔬Scientific Evidence
Naturally produced by body (fibroblasts). Production decreases 50% by age 50. Proven to increase skin hydration by 16% and reduce wrinkle depth by 10-20% (Pavicic study). Non-irritating in all studies.
⚡Important Warnings
- !Apply to DAMP skin only (or it draws water from deeper layers)
- !Use occlusive moisturizer on top in dry climates
- !Different molecular weights = different penetration depths
💡Fun Facts
- ★Body produces 15g of HA, degrades 5g daily
- ★Used in joint injections (same molecule!)
- ★Low MW (small) = deeper penetration
- ★High MW (large) = surface hydration
