Question

I used a facial wash for two days and developed a red rash. The ingredients listed are:

  • Sodium Lauryl Ether Sulfate
  • Cocamidopropyl Betaine
  • Cocamide DEA
  • Denatured Ethanol
  • Salicylic Acid
  • Triclosan
  • Methylisothiazolinone
  • Methylchloroisothiazolinone
  • Perfume

What could be causing this reaction, and which ingredients are potential culprits?

Answer

Skin Reaction to Facial Wash

Based on the ingredients you provided and your experience, the red rash you developed is likely a form of contact dermatitis. This can be caused by either irritation or an allergic reaction to one or more components in the facial wash.

Several ingredients in the list are known to potentially cause skin reactions:

  • Sodium Lauryl Ether Sulfate: A strong cleansing agent that can be irritating.
  • Cocamidopropyl Betaine: While often used in gentle formulations, it is a known contact allergen for some people.
  • Cocamide DEA: Can also contribute to irritation.
  • Denatured Ethanol: Alcohol can be drying and irritating to the skin.
  • Salicylic Acid: An active ingredient for acne that can cause redness and irritation, especially upon initial use.
  • Triclosan: An antibacterial agent that can cause irritation or allergy.
  • Methylisothiazolinone and Methylchloroisothiazolinone: These preservatives are common causes of allergic contact dermatitis.
  • Perfume: Fragrances are frequent triggers for allergic skin reactions.

The rapid onset of your symptoms suggests your skin reacted quickly to something in the product. To identify the specific ingredient causing the issue, patch testing by a dermatologist is usually required.

Recommendation:

  1. Stop using the facial wash immediately.
  2. Gently cleanse your face with plain water or a very mild, fragrance-free cleanser.
  3. If the rash does not improve or gets worse, consult a dermatologist for diagnosis and treatment.

Some ingredients from your list that are known potential irritants or allergens include Cocamidopropyl Betaine, Ethyl Alcohol, and Salicylic Acid.
