Lipstick, concealer and of course something for the eyelashes: Many women wear a variety of different cosmetics every day. But isn’t that harmful in the long run? How many cosmetics is too many?

In the EYVA blog, we look at the subject in more detail and explain what you need to pay attention to in daily use and what the dangers of excessive use of cosmetics are.

Uninterrupted popularity of beauty and skin care products

The cosmetics industry continues to enjoy great popularity. In fact, it is even on the rise, as the statistics show: in 2017, consumers spent almost EUR 13.6 billion on cosmetics, an increase of 0.5% over the previous year. This was announced by the Association of the Body Care and Detergent Industry.

And even though many say they can’t do without cosmetics, the question arises whether our skin could see them differently. Because we must always keep in mind that the body has its own processes of re-greasing and general regeneration – an “intervention” must therefore be carefully considered.

Ingredients in cosmetics can be part of the problem

And it focuses on the components. A glance at the back of the packaging reveals that a product contains or may contain many different ingredients. For some, users with sensitive skin in particular need to be careful.

Take the example of fragrances in cosmetics that can trigger allergies. With the multitude of substances used, it is then difficult to know exactly what causes the reactions.

Therefore, it helps to take a close look at the cosmetic products used and ask what is contained in which products. If necessary, a switch to natural cosmetics (where the likelihood of an allergy is lower) or products that work naturally (such as snow algae) is also helpful.

Science is also constantly searching for the effects of the substances used. Some are even suspected of causing disease or being harmful in the context of environmental protection. This is suggested, for example, by studies on silicones in hair care.

Especially when using (too) many cosmetic products, the term periodical dermatitis is often used.

What is perioral dermatitis?

Perioral dermatitis (also known as oral dermatitis, hostess disease or mannequin disease) is a non-contagious, harmless skin disease that often affects young and middle-aged women. Small blisters form on the face, mainly around the mouth and eyes. The skin does not produce enough fat due to excessive care. As a result, dandruff and dryness develop.

In turn, many affected people try to compensate with even more care (mainly moisturising creams), which of course aggravates the problem. Even cortisone ointments offer only temporary relief. The most effective therapy here is in fact to do without skin creams, as these are after all the main cause. This requires self-discipline, as a complete disappearance of the symptoms can take a long time.

Allergy to cosmetics – what to do?

But without a doubt the most common problem caused by the (excessive) use of many cosmetic products is, as already mentioned, allergies. Manufacturers are obliged to pay attention to minimizing the risks of the ingredients, but a contact allergy can still occur. Typical symptoms in this case are itching, redness, blistering or scaly skin.

Although avoiding the relevant substance is the best possible solution, there are other alternatives or other measures you should take:

  • Consult a doctor who can identify the exact cause.
  • Appropriate care (discussed with the doctor/allergist) helps to prevent or weaken the penetration of allergens.
  • If possible, generally avoid triggering substances.

The INCI declaration (International Nomenclature of Cosmetic Ingredients) also contains useful information. It provides uniform information for the description of substances in cosmetics.

What cosmetics do I really need?

Conversely, there is the question of how much or which cosmetic products are really needed and what you need to pay attention to. Of course, this cannot be answered at every level. But all too often, advertising has an effect on us – and so we buy a moisturiser, even if our skin doesn’t need it at all.

Instead, skin type is the most important factor when choosing the necessary cosmetic products. Even otherwise effective products can be harmful if they don’t correspond to your skin type. We have therefore also described how to recognise and care for your skin type. In this context, caution should also be exercised with cosmetic products that promise direct or immediate results.

In addition, generally make sure you don’t change products too often. This is often an additional burden on the skin.


In dealing with the subject, it becomes clear how important a certain cosmetic knowledge is. Very few users will be able to understand all the product information. But as far as compatibility is concerned, basic knowledge and awareness of problems alone can help.

As already mentioned, when choosing the right product and the real needs of our skin, skin type is one of the most important factors. So start with this step and then adapt to the specific needs of your skin.
