Hyaluronic acid (HA) is everywhere in skincare, but do you really understand how it works?
What is Hyaluronic Acid?
HA is a naturally occurring molecule in our skin that can hold up to 1000x its weight in water. As we age, our natural HA levels decrease.
Types of Hyaluronic Acid
Different molecular weights penetrate differently:
- **High molecular weight**: Sits on skin surface, provides immediate hydration
- **Low molecular weight**: Penetrates deeper, provides long-term hydration
- **Multi-weight formulas**: Offer the best of both worlds
How to Apply HA Correctly
The key to HA is applying it to damp skin. Without moisture, HA can actually pull water from your skin!
1. Cleanse your face 2. While skin is still damp, apply HA serum 3. Follow immediately with moisturizer to seal in hydration 4. In dry climates, always layer an occlusive on top
Common Mistakes
- Applying to dry skin
- Not following with moisturizer
- Using in very dry environments without occlusive
