Ceramides & Hyaluronic Acid: Their Role in Achieving Beautiful Skin
You've probably heard about ceramides and hyaluronic acid, and about how they can do a lot of good on the skin as a component of cosmetic products. But what exactly is hyaluronic acid, and what are the benefits of ceramides in creams? Here is the short answer - Ceramides and hyaluronic acid are both endogenous substances which, among other things, create firm and supple skin. A deficiency can lead to dry skin. Read one to discover how the two substances make skin fresh and beautiful, what happens when you have a lack of ceramides and hyaluronic acid, and what you can do about it.
What Are Ceramides & Hyaluronic Acid, and What Functions Do They Have In Regards to Skin?
Ceramides and hyaluronic acid are important for the optimal health of the skin. They're both product by the body, but act in different ways. Ceramides are lipids, which are fats that are produced in the sebaceous glands. Hyaluronic acid is a transparent, gel-like fluid that is not only produced in the skin but also in other areas of the body. Their concentration in the skin is particularly high.
Hyaluronic acid primarily binds water in the skin - more precisely, in the extracellular matrix. This area has ability to store several liters of fluid per gram. A high concentration of hyaluronic acid therefore means a high content of water, which makes the skin firm and plump. In addition, hyaluronic acid helps protects against damaging environmental influences and promotes cell renewal.
Ceramides ensure that transepidermal water loss does not occur too quickly by holding onto water in the skin. In addition, ceramides can reduce free radicals in the skin that destroy elastin and collagen. This helps prevent metabolic processes that can lead to hyperpigmentation and age spots. Ceramides hold skin cells firmly together in the uppermost skin layer. This not only keeps the fluid in the skin but also protects it from allergens and external aggressors. Ceramides are not only important for a healthy appearance, but also for a healthy functioning skin.
Cause & Consequences of a Lack of Ceramides and/or Hyaluronic Acid In The Skin
A lack of ceramides and hyaluronic acid is a consequence of the natural aging process. From the age of 25 the body gradually produces less of both. The consequences of this natural reduction is drier skin that appears less plump and shows wrinkles. Of course, this process varies by individual.
Other reasons for a low concentration of ceramides and hyaluronic acid in the skin are environmental factors, lifestyle and skin diseases. This effects the skin all over the body, which means that a lack of ceramides can manifest itself anywhere - such as dry, itchy skin on the legs. Ambient temperature also has an influence on the fat production of the sebaceous glands; at low temperature they produce less ceramides and the glandular glands contract. That is why many people have more issues with dry skin in winter.
Lacking in ceramides and hyaluronic acid isn't just a cosmetic problem - it can also have skin health impacts. When skin is dry the protective skin barrier is not as intact as it should be, so warding off external aggressors can be affected. This is why complaints such as skin irritation, contact dermatitis or even atopic dermatitis occur more quickly. This is why a lack of ceramides and hyaluronic acid should always be addressed.
What Can Be Done About a Lack of Ceramides and/or Hyaluronic Acid?
In order to balance or prevent a lack of ceramides and hyaluronic acid, the following three measures are important:
• A healthy lifestyle
• Dietary supplements
• Nourishing cosmetics.
A healthy lifestyle supports the natural regeneration of the skin. This includes drinking plenty of water, avoiding stress and getting enough sleep. Hot showers and internal heating deprive the skin of moisture. In winter, the skin is exposed to a frequent change between warm indoor air and cold outside air. It is therefore not surprising that the skin tends to dry out especially in this season. For those affected, it may be useful to nourish the skin with moisturisers enriched with ceramides and hyaluronic acid.
Skin care products have a direct effect on the outermost layer of the skin, the epidermis, where they counteract damage caused by missing ceramides and hyaluronic acid. The skin is not only able to absorb moisture, but retain is better as well.
The skin care range offered by CeraVe replenishes skin immediately after the first application. For this purpose, CeraVe uses hyaluronic acid as well as three essential ceramides. These are the so-called ceramides 1, 3 and 6-II, which also occur naturally in the skin and are important for a healthy skin barrier. If they are sufficiently abundant, it is more likely that the skin will keep moisture in and foreign bodies out.
In addition, CeraVe's products use MVE technology to provide long-lasting hydration to the skin. The technology is based on many small globules in which ceramides and hyaluronic acid are stacked on top of each other like the skin of an onion, gradually releasing them over an extended period of time.
