Hyaluronic acid is a substance that has gained immense popularity in recent years in the cosmetics and aesthetic medicine industries. It's a natural compound found in the human body that plays a key role in maintaining the youthful and radiant appearance of skin and hair, as well as maintaining proper joint function. Learn more!
What is hyaluronic acid?
Hyaluronic acid is a natural polysaccharide found throughout our bodies, especially in the skin, joints, and eyes. It's responsible for maintaining the proper level of tissue hydration and ensuring their elasticity and smoothness. With age, hyaluronic acid levels in the body decline, leading to wrinkles and loss of skin firmness.
But that's not all. What else is hyaluronic acid? What are its characteristics? Pure hyaluronic acid has the ability to bind large amounts of water in the skin. It's a safe ingredient, naturally occurring in the body, and therefore well-tolerated by most people. Hyaluronic acid can be used for skin and hair care, and even as joint support.
Types of hyaluronic acid
There are two basic types of hyaluronic acid: high-molecular-weight and low-molecular-weight. There's also ultra-low-molecular-weight hyaluronic acid (ULM) and sodium hyaluronate, a hyaluronic acid derivative, which dissolves better in water, making it an ideal cosmetic ingredient.
Types and names:
- HMW – high molecular weight hyaluronic acid with a molecular weight of 1 000 000-1 800,000 Da,
- LMW – low molecular weight hyaluronic acid with a molecular weight of 100,000-400,000 Da,
- ULMW – ultra low molecular weight hyaluronic acid with a molecular weight of 3,000-10,000 Da.
High molecular weight vs. low molecular weight hyaluronic acid
High molecular weight hyaluronic acid (HMWH) has a higher molecular weight, allowing it to remain on the skin's surface, creating a protective layer and preventing moisture loss. It is often used in skincare products to moisturize, smooth, and protect the skin from harmful external factors.
Low-molecular-weight hyaluronic acid, on the other hand, has a smaller molecular weight, allowing it to better penetrate the skin's layers and provide deeper hydration. It is used in skincare products to improve elasticity, smooth fine lines and wrinkles, and increase skin firmness.
Hyaluronic acid properties, or what does hyaluronic acid do?
There is no doubt that hyaluronic acid is a substance whose deficiency you will sooner or later feel.What does hyaluronic acid do that makes it so indispensable? First and foremost, it boasts many valuable properties that make it indispensable in beauty care. So how does hyaluronic acid work?
- has the ability to bind and retain large amounts of water, which provides the skin with adequate hydration,
- stimulates the production of collagen and elastin, supporting the regeneration and renewal of skin cells,
- may reduce the visibility of wrinkles and folds,
- creates a protective barrier on the skin, protecting it from the harmful effects of UV radiation and pollution.
Hyaluronic acid effects that you can also achieve include:
- delaying skin aging processes,
- face modeling or lip augmentation,
- improving the appearance of skin and hair,
- maintaining the proper hydrolipid balance,
- increasing the elasticity and viscosity of synovial fluid,
- improving joint mobility.
Also, remember that hyaluronic acid's properties allow it to naturally stimulate repair processes and accelerate the formation of new tissue. This acid is therefore essential for faster wound healing, skin regeneration, hair growth, and joint regeneration.
Hyaluronic acid for joints
It is the main component of synovial fluid, which is responsible for proper joint lubrication and cushioning. Its ability to bind large amounts of water ensures proper hydration and elasticity of joint cartilage. With age, hyaluronic acid levels in the body decline, which can lead to inflammation, pain, and joint stiffness.
There are two main forms of hyaluronic acid supplementation for joints:
- hyaluronic acid in the knee – involves injecting a hyaluronic acid preparation directly into the joint, most often the knee, to replenish its deficiency in the synovial fluid, thus improving the lubrication and shock absorption of the joint,
- Hyaluronic acid capsules or tablets – oral supplements containing hyaluronic acid are more readily available and can be used as a dietary supplement, supporting the body's production of hyaluronic acid. However, remember that hyaluronic acid tablets for joints will be just as effective as capsules. The only difference lies in the form of the supplement – some people prefer to swallow capsules, which are neutral in taste.
Hyaluronic acid for the face
Hyaluronic acid for the face offers numerous benefits. Its moisturizing, firming, and smoothing properties make it widely used to improve the condition of facial skin. Hyaluronic acid for the face helps maintain proper skin hydration, which prevents dryness, roughness, and flaking. In aesthetic medicine, hyaluronic acid is often used as a filler to reduce wrinkles and fine lines.
Hyaluronic acid for wrinkles can help prevent skin aging, maintaining a youthful appearance by moisturizing, firming, and smoothing the skin. Furthermore, hyaluronic acid is used under the eyes and on the face to improve facial volume and contour. Injecting hyaluronic acid into specific areas, such as the cheeks, cheekbones, or chin, can help achieve a fuller and more defined appearance.
Hyaluronic acid for face effects:
- hydration and rejuvenation,
- filling wrinkles,
- regeneration and renewal,
- relieving inflammation.
Do you know how to use hyaluronic acid on your face? It all depends on the cosmetic you choose. The most commonly available skincare products containing hyaluronic acid include moisturizing and regenerating creams and serums, at-home hyaluronic acid facial masks, and mesotherapy, a procedure involving the injection of hyaluronic acid into the deeper layers of the skin via microinjections. Hyaluronic acid for acne is also popular in the form of dietary supplements, which support skin hydration from within.
Hyaluronic acid for hair
Hyaluronic acid also has beneficial effects on hair. Applied to the hair, it deeply moisturizes, nourishes, and regenerates it from within. It also has the ability to fill gaps and damage in the hair shaft, strengthening its structure.
Moreover, hyaluronic acid for hair can stimulate hair follicles and accelerate the growth of new strands, and when used in the form of conditioners and masks, it creates a light, moisturizing coating on the hair, which smoothes it and adds shine.
Hyaluronic acid – how to use it depending on its purpose?
You already know the many properties of hyaluronic acid found in cosmetics and dietary supplements. You also know the results you can achieve by using it regularly, but how should you use hyaluronic acid? Primarily, it depends on the manufacturer's instructions. You'll use a cream differently, a face serum differently, and a hair mask differently still.
How to use hyaluronic acid in cosmetics? If you're choosing a cream or serum, apply the product to cleansed and toned skin on your face, neck, and décolleté, patting gently with your fingertips. Apply the mask to your face, avoiding the eye and mouth areas. Leave on for 15-20 minutes, then rinse with lukewarm water. If you're unsure how to apply hyaluronic acid to hair, it's important to strictly follow the manufacturer's instructions. The concentration of the active ingredients determines how long the product should be left on your hair.
Hyaluronic acid tablets
Hyaluronic acid tablets are one of the most convenient forms of supplementation with this valuable ingredient. Depending on the hyaluronic acid supplement you choose, you'll take it 1-2 times a day with a glass of water.
However, note that hyaluronic acid capsules may contain additional ingredients that support skin and hair. Therefore, before choosing a specific product, carefully check the product's ingredients.
Hyaluronic acid in cosmetics
Hyaluronic acid in cosmetics is a great solution for those struggling with dry skin and the appearance of wrinkles. If you want to restore your youthful appearance, choose a hyaluronic acid serum with a high concentration of active ingredients.
Remember to check how often you use your cosmetics. In some cases, hyaluronic acid serums are applied to the skin once or twice a week. Other products are designed for daily use, such as hyaluronic acid creams, which can be safely used both day and night.
Hyaluronic acid for drinking
Drinkable hyaluronic acid is a great choice when you want to replenish your body's levels of this valuable nutrient. The liquid form offers many advantages. What are they? First and foremost, drinkable hyaluronic acid produces results much faster than capsules or tablets, because smaller hyaluronic acid molecules are absorbed directly from the digestive system into the bloodstream, reaching the skin and other tissues. This supports skin hydration and firmness, while also stimulating the body's natural production of hyaluronic acid.
Hyaluronic acid for inhalation
An interesting form of hyaluronic acid is its liquid form with the addition of physiological saline. This inhaled hyaluronic acid is intended for people struggling with respiratory infections. Hyaluronic acid particles moisturize the mucous membranes, facilitating breathing and soothing the burning sensation of the nasal mucosa associated with dryness.
Hyaluronic acid inhalation is also recommended as a supportive treatment for allergies and asthma during the pollen season. Regular use of this treatment alleviates symptoms and provides a feeling of relief.
What to combine hyaluronic acid with?
Hyaluronic acid is a true treasure in skincare. However, to fully utilize its potential, it's worth knowing what other ingredients it can be combined with. If you're wondering whether hyaluronic acid and vitamin C can be combined, the answer is simple: not only can they, but they should. Vitamin C is a powerful antioxidant that, when combined with hyaluronic acid, will not only additionally moisturize the skin but also protect it from the harmful effects of free radicals.
What about the niacinamide and hyaluronic acid duo? Niacinamide, or vitamin B3, is an ingredient with properties that strengthen the skin's protective barrier. Combined with hyaluronic acid, it creates an excellent moisturizing and regenerating duo. Hyaluronic acid and retinol work differently, as retinol stimulates skin cell renewal, while hyaluronic acid provides adequate hydration, minimizing potential irritation.
What else can you combine hyaluronic acid with? A great combination is collagen and hyaluronic acid. Collagen is a protein responsible for skin elasticity and firmness. Combining it with hyaluronic acid supports skin regeneration, reduces wrinkles, and improves skin density. Ceramides and hyaluronic acid, on the other hand, help strengthen the epidermal barrier and restore moisture.
It's also worth noting that hyaluronic acid, like Botox, is used to improve the appearance of the skin. What's the difference between them? Hyaluronic acid and Botox are two substances with different effects. Botox relaxes muscles, while hyaluronic acid fills wrinkles and moisturizes the skin. Combining them can yield better rejuvenating results.
What destroys hyaluronic acid?
We've already mentioned that hyaluronic acid, like elastin and collagen, simply declines in the body with age. However, there are certain factors that destroy it, regardless of your age.
What destroys hyaluronic acid and what to avoid? Ultraviolet radiation from the sun can contribute to the degradation of hyaluronic acid in the skin, leading to moisture loss and wrinkle formation. Therefore, regardless of the weather, use protective cosmetics with a high SPF.
Additionally, the body contains natural enzymes called hyaluronidases, which break down hyaluronic acid. Their excessive activity can lead to the substance's rapid breakdown. Ideally, these enzymes regulate hyaluronic acid levels in the body. However, when this balance is disrupted, remember to include more antioxidants in your diet, engage in regular physical activity, and use hyaluronic acid supplements.
Hyaluronic acid side effects
Wondering if hyaluronic acid is harmful? Although it's a substance naturally occurring in our bodies, it's worth knowing the potential side effects associated with its use. One of them is an allergy to hyaluronic acid.Symptoms may include redness, swelling, itching or burning at the application site.
After procedures such as wrinkle filling, lip augmentation or facial contouring, allergic reactions to hyaluronic acid may occur, causing symptoms such as bruising and hematomas, pain and discomfort, and even facial asymmetry.
Dietary supplements with hyaluronic acid are usually well tolerated, but in some cases side effects may occur, such as headaches, nausea, or diarrhea.
Hyaluronic acid side effects after subcutaneous injection include pain and hypersensitivity at the injection site, as well as inflammation and swelling. Hyaluronic acid under the eyes, on the other hand, may cause allergic reactions, granulomas, and other inflammatory reactions.
Hyaluronic acid contraindications
Although hyaluronic acid is a natural substance found in the body, its synthetic administration is not always safe. Hyaluronic acid contraindications include avoiding mesotherapy in cases of hypersensitivity to the preparation, active skin inflammation (e.g., acne, psoriasis), and certain autoimmune diseases, which can cause irritation after hyaluronic acid injection.
What about hyaluronic acid during pregnancy? The safety of using the substance during pregnancy and breastfeeding has not been fully studied, so it is recommended to avoid its use during these periods. This is regardless of whether hyaluronic acid is included in cosmetics during pregnancy or cosmetic treatments using this ingredient.
Hyaluronic acid is a natural beauty ally that can help maintain youthful and radiant skin, natural hair hydration, and good joint mobility. Thanks to its moisturizing, regenerating, and plumping properties, it has become an indispensable ingredient in many products—cosmetics and dietary supplements—as well as cosmetic and aesthetic medicine treatments.
