If you’ve already discovered the age perfecting benefits of using skincare products containing hyaluronic acid, you may already consider the potent ingredient as magic. Hyaluronic acid (HA) is often touted for its ability to reverse or stop aging. In news reports, you might have heard of hyaluronic acid as the “key to the fountain of youth.
But acid sounds scary, right? Don’t worry HA will not melt your face. All substances that have a pH value less than 7 are considered acidic and all substances with a pH value greater than 7 are said to be basic or alkaline. In fact, our skin pH ranges from 4.5 to 6.5 which means it’s always on the slightly acidic side. When we apply mildly acidic products, they actually soothe the skin, helping it retain moisture and strengthening the skin barrier even more. On the other hand, highly acidic substances such as citric juice, which has a pH of about 2 or 3, are likely to cause things such as skin irritation, sun sensitivity, and skin hyperpigmentation.
INTRODUCING PREVISE ZEROFRAGRANCE HYALURONIC MOISTURIZER
Hyaluronic acid is essentially a large sugar molecule, what chemists call a polysaccharide. A giant among sugar molecules, Hyaluronic acid has a molecular weight of anywhere from 600,000 to 1,000,000 units compared to regular table sugar which has a molecular weight of about 340 units (Daltons). Its structure and this large weight give it the ability to hold between 500 and 1000 times its own weight in water. That’s why our bodies use it to hydrate tissues and lubricate joints.
HA’s ability to retain moisture makes it particularly helpful in skin care products because it creates a cushion to help plump the appearance of aging skin. Its water-binding and water-attracting attributes fill up the spaces between the connective fibers of collagen and elastin in the dermis. The skin’s dermis layer is made up of about 70 percent water and claims nearly 50 percent of your body’s total HA allotment.
You may be asking, “What’s the relationship between hydration and skin aging?” Well, skin aging is associated with loss of skin moisture and the key molecule involved in skin moisture is HA. Unfortunately, HA production decreases with age and adults have only 1/20 the HA of a baby.
Youthful skin retains its turgor, resilience and pliability, among others, due to its high content of water. That changes over time as our skin’s aging process is influenced by the hormonal changes we experience over the course of our lives. Reductions in our hormone levels influence our skin because androgens stimulate collagen production and estrogens stimulates the production of HA. Collagen and HA are vital to maintaining the skin’s layers and structure. Collagen gives the skin its firmness, and HA nourishes and hydrates the collagen. So, as we age, our skin naturally becomes drier, less elastic and it begins to wrinkle.
So how can you maintain youthful looking skin despite the forces of nature? The key to maintaining a smoother, younger looking complexion is keeping your skin hydrated. But, many people confuse dry (meaning oil dry) skin and dehydrated skin (meaning moisture dry). Applying richer, oilier products to dehydrated skin may temporarily make the skin feel softer, but they will not actually help eradicate the problem. The key to treating dehydrated skin is to exfoliate and use high-quality, nontoxic skin care products that are rich in moisture and contain humectants, such as HA.
The special HA used in our Previse recipes stimulates the expression of ZO1 and Occludin proteins that are constitutive proteins of tight junctions. This improves cell cohesion and the barrier function of the skin. Moreover, thanks to the high hygroscopic ability of the HA, it maintains hydration in the skin through a water reservoir function in the dermis. Through both of these complementary actions, Hyaluronic acid regulates the internal hydration of the skin and improves firmness by stimulating collagen in the dermis.
