What is hyaluronic acid for the skin?
Hyaluronic acid (HA) is an intricately shaped carbohydrate molecule found in abundant quantity in the human body. Its main function is to deliver moisture and nourishment to other cells for optimal functionality. This hydrating cell was first isolated from vitreous humour—the jelly-like substance—of cow eyes by 2 scientists from Columbia University, Karl Meyer and John Palmer. With further research, hyaluronic acid was proven to be an excellent humectant that draws moisture to the skin from the surroundings. Since its skincare benefits are aplenty, HA is now available in various forms, from lightweight hydrating facial mist to hydrating cream.
What are the benefits of hyaluronic acid for skin?
Since hyaluronic is a humectant, it works by absorbing moisture from the surrounding into the skin and prevent water loss. In fact, its water binding is too good that a single gram of hyaluronic acid is able to hold up to 6 litres of water! Hence, when applied onto the skin, it maintains a good hydration status and turns back time on ageing signs contributed by dehydration and dry skin. In addition, HA also helps to erase fine lines. As it immediately hydrates the skin, any superficial lines are also instantly yet subtly lifted for a smooth complexion. Besides that, HA also helps to treat sunburns and minor wounds due to its calming and hydrating properties. Furthermore, since hyaluronic acid exist naturally, most people can tolerate hyaluronan-based products rather well.
What does hyaluronic acid do for skin?
Nowadays, hyaluronic acid is also expressed as the sodium salt version, sodium hyaluronate, as it can be absorbed into the deeper layers of the skin much easily. Once applied, it hydrates dehydrated skin adequately. Well-regulated hydration level also prevents release of excessive sebum. Proper hydration ameliorates the appearance of ageing signs like fine lines and flakiness.
