Hyaluronic acid is one of the most popular ingredients in skincare, often praised for delivering intense hydration and a plump, glowing complexion. But while it plays a role in moisturizing the skin, its effects may not be as deep as many believe.
Understanding Skin Absorption The skin’s outer layer acts as a barrier, allowing only very small molecules to pass through. In general, ingredients need to be under 500 Daltons to effectively penetrate.
Where Hyaluronic Acid Falls Short Hyaluronic acid has a very large molecular size, which prevents it from reaching deeper layers of the skin. Instead, it sits on the surface, attracting moisture and creating a temporary smoothing and plumping effect.
What This Means for Your Skin While you may notice immediate hydration, these results are often short-lived and don’t address deeper skin needs.
Ingredients That Go Further For more effective, long-term hydration and skin support, consider: • Glycerin -helps draw moisture into the skin • Peptides -support repair and improve skin function • Ceramides -strengthen the barrier and reduce moisture loss
