What are allergens?

Allergens are substances that come from outside the body. Most allergens are substances that simply occur in nature. These substances are basically harmless. After entering the body (through nose, mouth or skin contact), they can cause allergic symptoms in sensitive people.

Allergens can appear in cosmetics, laundry detergents, and personal care products. Some people are allergic to perfumes and / or dyes that contain these products.

known allergens

Many substances can cause a skin allergy. This happens more often with some substances than with others.

Common allergens are:

Metals (such as nickel and chromium)




Paraphenylenediamine (used in black hair dye and tattoos, among others)

What is a skin allergy?

You can develop a skin allergy if your skin comes in contact with an allergen or other substance to which you are (over) sensitive. Usually your immune system protects you from harmful organisms. However, if this system is set incorrectly, your body will also react to harmless substances.

An allergic reaction in your body can manifest itself in many ways, for example in your respiratory tract, digestive tract, or in shock. But it can also show on your skin. It can swell, dry, scarce, red, or burn. You may also experience itching.

What exactly does hyaluronic acid do in the body?

Hyaluronic acid performs important functions in the body related to healthy skin. It regulates the hydration capacity, the metabolism and the regeneration capacity of the skin. Hyaluronic acid is usually found in the dermis, but the substance is also found in the epidermis. The substance retains a reserve of water in the dermis to prevent drying out of the epidermis and to maintain optimal water balance. Hyaluronic acid has a dynamic renewal of less than a day in the body.

For the big picture: Hyaluronic acid plays an essential role in maintaining healthy connective tissue, skin elasticity and wound healing. Hyaluronic acid also maintains flexibility in joints, blood vessels, and fibroids. The fibroblast is the main cell of connective tissue, a non-elastic fiber that keeps the skin firm.

Why is hyaluronic acid care important?

The body’s ability to make and renew hyaluronic acid (and collagen) declines with age, research shows. Additionally, extreme weather conditions including heating in winter, certain skin care products and underlying issues can cause small breaks in the protective skin barrier, causing water to leak.

Hyaluronic acid plays a vital role in maintaining healthy connective tissue, skin elasticity and wound healing “

The human body is able to produce and renew hyaluronic acid on its own, producing approximately 3g of HA per day. An average person has around 15 grams of hyaluronic acid in their body, which is distributed throughout the body tissue. The skin absorbs hyaluronic acid very well when, for example, it is smeared on the face.

What does hyaluronic acid do?

The magic ingredient has already been proven in scientific circles as a substance that can provide the skin with a lot of moisture – one gram of hyaluronic acid can absorb up to six liters of water. Six liters! It is a so-called humectant and loves water. What’s even more impressive is that hyaluronic acid can do this for your skin without going overboard and spraying the skin. The surplus can (surprisingly) also damage moisture, as it breaks down substances that normally keep the skin’s surface intact. Plus, Hyaluronic Acid revitalizes the skin separately from the top layer, leaving the skin feeling softer, smoother and more radiant. It also reduces the appearance of fine lines and wrinkles. A little extra: it is suitable for all skin types, including sensitive (allergic) skin, even prone to rosacea.

In summary:

  • Hyaluronic acid supplies the skin with the perfect dose of moisture.
  • Hyaluronic acid fades fine lines and wrinkles;
  • Hyaluronic acid makes the skin smoother and firmer;
  • Hyaluronic acid strengthens the protective layer of the skin;
  • Hyaluronic acid is anti-inflammatory, so (acne) wounds heal faster;
  • Hyaluronic acid strengthens the skin with antioxidants against free radicals.

What is Hyaluronic Acid?

We already have a natural source of hyaluronic acid in the body, which is stored in our connective tissue, skin, and nervous tissue. This sugar molecule is a water lover (the natural form is linked with collagen on the one hand, and binds with water on the other hand for strength) and ensures that the skin stays hydrated and the joints stay flexible. Hyaluronic acid is therefore a basic element to keep our body flexible and rich in humidity.

Hyaluronic acid is linked to collagen on the one hand and binds to water on the other hand, for plump and radiant skin “

What is hyaluronic acid and why does it work wonders for your skin?

Hyaluronic acid is a sip of this skin care ingredient which is widely used in serums, sheet masks, and moisturizers popular today. When we think of “acids”, we must think of the peel, but hyaluronic acid has nothing to do with the peel. It is also far from being “aggressive”. Many dermatologists swear by hyaluronic acid (English name) for everyday use, as this molecule binds to the water in the skin and, so to speak, fills your skin.

Think: beautiful “full” skin that young girls often have naturally. Indeed, baby’s skin is cracked. Perhaps you have noticed over the years that your skin has lost some of this volume? Especially if you are also dealing with the yo-yo, which causes your skin to lose its firmness. In addition to that, it is also a natural filler for fine lines and wrinkles. Think of hyaluronic acid, think of a wet and glowing effect. Certainly, hyaluronic acid has even more to offer, and we would be happy to explain it to you in detail.


Whether you need to adapt your routine to winter or summer depends on your skin. If you have found the right routine for your skin, you don’t necessarily need to adapt it to the different seasons. Summer or winter, rain or sun: the basic needs of your skin remain the same. If your skin does not change with the seasons, there is no need to change your routine. When you go on vacation, take miniatures of your favorite products to keep your skin healthy and radiant all year round. Because of your personal preferences in the summer, you may prefer to use products with a light texture and give your skin extra moisture in the winter with, for example, the Moisture Renewal Oil Booster or a moisturizing mask. In this case, you can adjust your routine accordingly, but remember that this does not have to apply to everyone. After all, no two skin types are the same.


Gradually, you may find that your skin needs more attention to treat specific skin problems.


If you follow the right routine for your skin, you will notice a clear difference. Your skin is smoother and looks brighter and healthier. If you have persistent skin problems, it may take some time to see visible results. If you are starting a new routine and/or new products, use them at least 2-3 times a week. This is the only way to see the difference and to know if this routine is right for you.


Your skin type determines the texture that best suits your skin. To find out what your skin type is, see how your skin reacts after washing with a facial cleanser. If your skin is tight and uncomfortable, you have dry skin, if your skin shines immediately after cleansing, you have oily skin, and if you see both oily and dry areas, you have combination skin. It is also possible that after cleansing, your skin is thin and does not shine. In this case, you have normal skin. Learn more about skin types.

A general guide to choosing the right texture for your skin type: for normal to dry skin, choose a cream or lotion with a texture that nourishes and moisturizes your skin; for oily skin, choose light-textured products or a gel that doesn’t clog pores; for combination skin, use a light-textured product on oily areas of your skin and a lotion-textured product on dry areas of your face.
