Frequently Asked Questions

Apply HA to wet or dry skin?

Always damp skin. HA draws moisture; on dry skin in low humidity it can pull water from deeper layers.

Can I use HA every day?

Yes, twice daily for all skin types including sensitive.

Does molecular weight matter?

Yes. High MW hydrates surface, low MW penetrates deeper. Multi-weight is best.

Can HA cause breakouts?

Pure HA is non-comedogenic. Some serums add oils/silicones that may clog pores.
