Polyglutamic Acid vs Hyaluronic Acid: Which Hydrator to Choose

Polyglutamic acid sits on skin's surface for immediate plumping while hyaluronic acid penetrates deeper for lasting hydration.

1. Apply polyglutamic acid to damp skin. Pat it onto clean, slightly wet skin in the morning or evening. It forms a film that locks in moisture immediately. Think of it as your skin's protective barrier.
2. Layer hyaluronic acid under moisturizer. Use on damp skin, then seal with cream or oil. HA draws moisture from the air and deeper skin layers. Without a moisturizer on top, it can actually pull water from your skin.
3. Use polyglutamic acid for instant results. Perfect before makeup or when your skin feels tight. The surface-level hydration gives immediate bounce and smoothness that lasts hours.
4. Choose hyaluronic acid for long-term hydration. Better for daily routine building and deeper moisture needs. It works slower but penetrates further, supporting your skin's natural moisture barrier.
