You are SO welcome. I really love doing it. And, I feel a strong connection to all of you. It’s one of those not entirely rational things: it just feels right. Ok… the science part of my brain is rebelling now. 🙂 Hyaluronic acid or “HA” is being found in many more skincare products. In my opinion, it’s a bit of both, meaning marketing hype and real.
What does hyaluronic acid do in the body?
- Our cells make it, a lot of it!
- The “glue” between our cells is mostly hyaluronic acid (the extracellular matrix).
- Also found in joints (synovial fluid) and it coats our cartilage cells.
- In skin it helps with wound and UV repair and helps attract water molecules to the skin (skin hydration).
- In skin, besides the above, it helps to scavenge free radicals which may damage cells.
Is HA in skincare products helpful?
- Not as much as you might think because HAs are big molecules and big molecules don’t get through the outer skin layer (the epidermis) easily.
- It helps with superficial hydration mostly. Try using it as a base layer under your regular moisturizer or sunscreen for extra hydration.
- In my opinion (not much science on the best percentage), the 1.5% HA isn’t worth it. Look for gels that have it listed in the top 1-2 ingredients.
- Fabulous as the non oily base for patients with acne and oily skin because it rarely causes breakouts.
I hope this helps,
