Cosmetic Allergies - Bangkok Aesthetic Clinic

Cosmetic Allergies

Cosmetics can be divided into 4 product categories:

  • Skin care
  • Sun protection
  • Hair care
  • Deodorants
The most important thing in choosing these products is their high quality and reliability. This is to prevent untoward incidents of allergic reactions and irritations, which are common skin issues.

Irritant Contact Dermatitis

Symptoms of irritation consist of dry, red rash and itchy skin. In severe cases, the skin may be burnt and occur through the consistent use of cosmetic products containing AHA ingredients or not being certified. Allergic contact dermatitis is a result of exposure to specific substances contained in cosmetics, leading to allergic reactions.

Common Symptoms of Allergies

  • A burning pain sensation and itchy skin – this occurs after the use of cosmetics for a period of time, normally for 2 days. Should this happen, discontinue the product immediately, which should result in the symptoms disappearing. The skin around the eyes is most sensitive and is where symptoms are most present.
  • Atopic dermatitis, urticaria and swelling rash – normally, these symptoms are not severe; there may be swelling in particular the eyelid areas. However, if symptoms are severe, the swelling and the rashes on the face could affect the respiratory systems.
  • The presence of white marks on the face – this could occur as a result of using cosmetics containing hydroquinone and skin whitening products. The FDA has banned the use of hydroquinone in cosmetic products. Unfortunately, there are still some medical practitioners using this type of product in their treatments.
  • The appearance of black rashes on skin – sometimes, the kind of cosmetic products – perfumes and fragrances – used can cause black rashes on skin following excessive exposure to sunlight.
  • Nail and hair fragility – this could happen due to a heavy usage of cosmetic products that contain high chemical agents, such as hair colour substances and nail polish. However, an appearance of acne should not be taken as a form of allergic reaction, as this is more of a result of long-term usage of cosmetic products.

Types of Cosmetic Products Causing Allergies

Facial Cleaning Products
  • Primarily, they are soaps, creams, and gels for cleansing the skin of the face and body. Products containing deodorants with a combination of preservatives and fragrances are the primary cause of rashes, redness and itchy skin.
Skin Care Products
  • Astringent or toner is used to eliminate impurities in the pores after cleansing. However, the compounds contained in the products such as alcohol and salicylic acid can cause irritations, redness, itchiness, pain or burning sensations. These are symptoms of allergic reactions.
  • Moisturisers – red blisters and itchy skin are the results of allergic reactions to such compounds in moisturisers as propylene, glycol, protein and some vitamins.
Sun Protection Products
  • Sunscreens – allergies to sunscreen application can be caused by direct exposure to the sun. Substances that can cause allergy symptoms include PABA (Paramino Benzoic Acid) and oxybenzone. There may also be allergies to preservatives or colouring ingredients in the products.
Hair Care Products
  • The chemicals including sodium and ammonium lauryl sulphate in certain shampoos and conditioners increasingly generate irritation, itchiness or redness of the scalp.
Deodorant Products
  • Perfume and fragrances may create allergic reactions resulting in rashes. Additionally, colour cosmetics including eye shadow, blush or lipstick can cause inflammation, redness and itchiness.

Cosmetic Substances Resulting in Allergic Reactions

Fragrance and preservative substances are ingredients increasingly found in cosmetic products.


  • The most common cause of allergy symptoms.
  • It is vital to read and understand the labels on cosmetic products before purchase. The labels normally state:
  • Unscented – the product contains no fragrances.
  • Hypo-allergenic – the product contains perfumes.
  • A mixture of preservatives is added to cosmetic products to prevent the growth of bacteria and fungi, which can lead to skin infections.
  • It prevents the deterioration of product quality.

Dealing with Cosmetic Allergies

  • Immediately discontinue the use of the suspected cosmetics causing the allergy. A simple method of determining the allergic reactions to a cosmetic is by applying a small sample of the product on the palmer side of the forearm for 2 consecutive days. An appearance of rashes within those days will indicate an allergy to the cosmetics.
  • Conducting a patch test to determine what cosmetics and their chemical ingredients cause allergic reactions. The results normally take 2 consecutive days to analyse and another 2 days to examine the overall results. The appearance of a red rash on the tested areas means that there is certainty of an allergic reaction.
  • A highly experienced dermatologist should be consulted to determine the primary cause of the skin condition, after which the most effective treatment methods can be devised.
