The two names (hyaluronic acid and sodium hyaluronate) are used interchangeably in the beauty industry, but they do have their differences.What is this so-called “hydration miracle” called hyaluronic acid that seems to be popping up in everyone’s favorite skincare products? Hyaluronic acid is a naturally-occurring molecule (specifically a polysaccharide) found in skin, hair, eyes, joints and nerves that acts as a cushion to promote collagen and elastic, keeping us looking and feeling young. Hyaluronic acid holds 1,000 times it’s weight in water, so it is literally a super magnet for moisture.
Along with proper sun protection, adequate skin hydration is crucial to combat the signs of aging, which is why hyaluronic acid, or it’s sister ingredient, sodium hyaluronate, is a must. Sodium hyaluronate is a smaller molecule, which allows it to more easily penetrate the skin.
