FAQ
Q1: Can hyaluronic acid dry out skin?
A: In very dry air, HA can pull moisture from the skin instead of the air — applying it to damp skin and sealing with an occlusive prevents this.
Q2: Why does it happen?
A: HA binds up to 1,000x its weight in water (Papakonstantinou 2012); with no water in the air, skin becomes the source.
Q3: How do you prevent it?
A: Apply HA on damp skin, follow with moisturizer, and in arid climates use a humidifier or skip layering.

One-Sentence Summary
Hyaluronic acid can dehydrate skin only in very dry air; applying it damp and sealing with an occlusive prevents moisture loss.
