Hyaluronic Acid: A vital molecule for skin hydration

Introduction

Skin aging is a natural process which occurs due to two distinct mechanisms: intrinsic and extrinsic ageing. Healthy and young skin has ability to retain moisture, resilience and pliability whereas daily exposure to UV rays, environmental stressor and toxins triggers the process of aging which leads to loss of moisture. The key molecule involved in maintaining skin moisture is Hyaluronic Acid that has unique capacity of retaining water.

Benefits

In the realm of skincare, this powerful molecule has revolutionized the way we approach skincare, providing a fountain of youth for our skin.
Hyaluronic acid acts as a lubricant and cushioning agent, promoting hydration and maintaining the elasticity of our skin. However, as we age, the production of hyaluronic acid decreases, leading to the appearance of fine lines, wrinkles, and dryness.
Hyaluronic Acid with a low molecular weight of 20–300 kDa passes through the stratum corneum, while high molecular weight (1000–1400 kDa) is largely impermeable which makes a protective layer on skin.

Conclusion

Hyaluronic acid is undoubtedly a game-changer in the world of skincare. Its ability to hydrate, plump, and rejuvenate the skin makes it a must-have ingredient for anyone seeking a youthful and radiant complexion. Incorporating the right hyaluronic acid with different molecular size into daily skincare routine unlocks the secret to maintain healthy, glowing skin at any age.
