Skin allergies – how to recognize them? Allergy to cosmetic ingredients

Have you noticed redness, irritation or an itchy rash after applying a new cosmetic? It could be an allergy to ingredients in cosmetic products. Sensitization to a cosmetic is nothing more than a defensive reaction of the skin against an ingredient it has just come into contact with. However, this does not mean that all cosmetics can irritate us, sensitize us. Most often, it only takes 1 ingredient to cause an adverse reaction.

Cosmetic Dermatis

Cosmetic Dermatis, or cosmetic dermatitis, is an allergic reaction caused by contact with a sensitizing substance in a cosmetic. The most common allergic reaction to a cosmetic is contact eczema. It occurs where the cosmetic product is applied. It usually appears after contact with the allergen and usually subsides after a few days. I occur in the form of irritation, erythema, contact dermatitis, urticaria or photosensitization.

Causes of increased susceptibility to allergic reactions caused by cosmetics:

  • frequent use of cosmetics with irritants, frequent change of cosmetics or improper care not matched to the skin type;
  • genetic conditions, sensitive skin, vascular skin;
  • excessively dry skin;
  • endocrine disorders;
  • air pollution and other negative environmental factors such as smog;
  • long-term acid-base imbalance of the skin;
  • stress.

Types of sensitization, caused by cosmetics:

  • irritant contact dermatitis (irritant cosmetic dermatitis) – is located where the cosmetic was applied, its intensity depends on the amount of substance used and the time of exposure to the skin,
  • specific allergic reaction (allergic cosmetic dermatitis) – occurs in people with a genetic predisposition to allergic reaction. Skin irritation can also occur in areas where the cosmetic has not been used.

Symptoms and sensations:

  • Subjective: burning, itching, discomfort, noticeable immediately after applying the cosmetic.
  • Objective: redness, peeling, pustules, papules, blisters, blisters.

Symptoms of sensitization may resolve on their own or consultation with a doctor is required. Note, however, that scratching, can lead to discoloration and scarring.

The most common allergens in cosmetics:

The cosmetics industry is thriving. Non-stop new active ingredients and cosmetics are being developed.

The most common ingredients that cause an allergic reaction include:

  • Preservatives – protect the cosmetic from microorganisms.
  • Fragrances – are a common source of allergic reactions. Sensitive people prone to allergies should choose fragrance-free cosmetics.
  • Metals – titanium dioxide and zinc oxide are often found in cosmetics. Titanium sensitizes very rarely, but an adverse reaction after contact with zinc happens more often. Sensitization can be caused by currently popular products with silver and gold additives.
  • Dyes – especially in products for hair dye and eyebrow and eyelash tinting.

Allergy test – how to find out if a cosmetic is allergenic

It is advisable to exercise extreme caution when using cosmetics with new, unfamiliar active ingredients. It is also a good idea to check invisibly if the cosmetic makes us allergic. We suggest applying a small amount to the skin, for example, behind the ear, on the jawline and on the upper arm.

After application, wait 24 hours. If there is no irritation, it means that our skin tolerates it well.
