What are the manifestations of skin care product allergies?

Skin care products are a type of product used by many women to improve skin quality and protect their skin. Since skin care products contain a variety of substances, they may have side effects on some people with allergies and cause allergies. Allergies to skin care products generally manifest as symptoms such as contact dermatitis, eczema, spasmodic cough, cheilitis, perioral dermatitis, and hormone-dependent dermatitis, which require timely treatment and care.

1. Allergic reaction

For some people with allergies, the use of certain cosmetics, such as the permanent dyes dibromofluorescein and tetrabromofluorescein in lipstick, and cosmetics containing lanolin, various fragrances and preservatives, can cause allergic contact dermatitis. High concentrations of perfume, deodorant, and hair lotion can cause various allergic reactions in some people with allergic constitutions, causing spasmodic coughs, allergic rhinitis, conjunctivitis, urticaria, etc.

2. Contact dermatitis and eczema

About 5-10% of people develop contact dermatitis due to the use of cosmetics, and 2-5% develop contact eczema due to cosmetics, which accounts for about 40% of facial dermatitis. This type of cosmetics mainly includes: skin care products, hair products and makeup products, followed by nail polish, perfume, cleaning products, shaving products and sunscreen products. Most of these products contain added fragrances and preservatives, so the most common allergens in cosmetics are caused by fragrance ingredients and preservatives.

3. Cheilitis

Cheilitis is a common condition that causes sensitivity to lipstick. The main allergens that cause sensitivity after using lipstick are preservatives and fragrances. In addition, the solvent that dissolves the pigment is also one of the irritating factors. In addition, impurities in the matrix such as oil, wax, cocoa butter, etc. may also cause sensitive cheilitis.

4. Perioral dermatitis

Perioral dermatitis was initially thought to be related to photosensitivity and to occur periodically, but recently it has been discovered that cosmetics can cause irritation, especially moisturizing creams, night creams, and cleansing milk. The clinical manifestations are very similar to rosacea and may be accompanied by mild itching. Repeated use of corticosteroids or ointments should be avoided at this time. The beauty care program recommends using restorative methods after acute inflammation has been alleviated.

5. Hormone-dependent dermatitis

Hormone-dependent dermatitis occurs when people with facial skin problems use hormone-containing products instead of cosmetics and use them on normal skin for a long time, forming a dependence. Illegally adding hormone ingredients to drugs or non-drugs in order to make huge profits.
