Hyaluronic Acid
Hyaluronic Acid, also known as HA, is a powerful humectant that's naturally present in our skin, connective tissues, and eyes. It has the unique ability to hold up to 1000 times its weight in water, making it a hero ingredient for skin hydration.
Skin Care Benefits of Hyaluronic Acid
-
Skin Hydration The primary hyaluronic acid benefit is its outstanding capacity to attract and hold onto vast amounts of moisture. This helps in skin hydration and keeps the skin looking plump and fresh. The ability of Hyaluronic Acid to retain moisture ensures that skin doesn't lose hydration throughout the day, leading to long-lasting softness and glow. (1) (2) (3) (4)

Boosts Skin Elasticity: Hyaluronic acid helps improve skin elasticity by replenishing moisture levels, thereby reducing the appearance of fine lines and wrinkles. Its hydrating properties give the skin a soft, supple, and youthful appearance. Over time, this effect helps to maintain the skin's natural elasticity, resulting in a firmer, more resilient complexion. (1) (2) (3)

Strengthens the Skin Barrier: By preserving moisture, hyaluronic acid reinforces the skin barrier, the outermost layer of skin which prevents damage from environmental aggressors. This reinforcement results in a fortified skin barrier that can better withstand environmental stressors, thus aiding in the overall health and resilience of the skin. (1)

Skincare Products with Hyaluronic Acid
Suitable Skin Types
Hyaluronic acid is generally well-tolerated by all skin types. It's particularly beneficial for dry and mature skin due to its hydrating properties, but it can also be useful for oily and combination skin types as it's lightweight and doesn't clog pores.
Origin and History
Hyaluronic acid is a naturally occurring substance in our bodies, found in our skin, eyes, and connective tissues. Its ability to retain water contributes to maintaining moisture levels in our tissues. The use of hyaluronic acid in skincare products started in the 20th century, and it has become a star ingredient due to its excellent moisturizing properties.
Hyaluronic acid was initially discovered within the eyes of cows during the 1930s. The scientist Karl Meyer and his assistant, John Palmer, first identified this substance while studying the vitreous humor of bovine eyes, which is the clear gel that fills the space between the lens and the retina. They noticed the compound had a high viscosity, allowing it to maintain the eye’s shape and protect the delicate structures within. This intriguing discovery led to the compound being named "hyaluronic acid" – "hyaloid" meaning "glass-like" and "uronic" because of its high uronic acid content. Following this discovery, hyaluronic acid has been studied extensively and it’s now recognized for its key role in skin health, wound healing, and overall body wellness. It’s fascinating to consider that our understanding of this beneficial compound all began from studying the eyes of cows!
Today, we find it in a variety of forms such as topical hyaluronic acid serums, creams, and even injectables. Its form varies from sodium hyaluronate to hydrolyzed hyaluronic acid, with differences mainly in the size of hyaluronic acid molecules and their ability to penetrate the skin.
Complementary Ingredients
-
Vitamin C: When it comes to aiding skin hydration, Vitamin C works wonderfully alongside Hyaluronic Acid. Vitamin C's antioxidant properties help to protect the skin from environmental damage and stimulate collagen production. This process aids the Hyaluronic Acid in maintaining skin elasticity and reducing the appearance of fine lines and wrinkles.
-
Retinol: Retinol, another key player in the skincare game, pairs well with Hyaluronic Acid. Retinol accelerates skin cell turnover, revealing fresh, healthy skin underneath. However, it can also cause dryness. That's where Hyaluronic Acid steps in, replenishing lost moisture and buffering potential irritation caused by Retinol.
-
Niacinamide: This powerhouse ingredient supports Hyaluronic Acid by improving skin barrier function, which helps to retain the hydration that Hyaluronic Acid provides. Niacinamide also reduces inflammation and hyperpigmentation, complementing Hyaluronic Acid's skin-improving effects. With both in your routine, you'll be well on your way to a plump, glowing complexion.
