- AHyaluronic acid serum
- BAlgae-based mask
- CAloe vera extract
- DKaolin clay mask
Show answer & explanationAnswer & explanation
Correct answer: B. Algae-based mask
Many algae and seaweed products can cause allergic reactions in individuals with shellfish allergies due to cross-reactivity. It is crucial for estheticians to identify and avoid such ingredients.
Why the other options are wrong
- A. Hyaluronic acid is a humectant naturally found in the body and is not related to shellfish.
- C. Aloe vera is a plant extract and is not typically associated with shellfish allergies.
- D. Kaolin clay is a mineral-based ingredient and does not pose a risk for shellfish allergies.
Shellfish Allergy Cross-Reactivity
Individuals with shellfish allergies may experience allergic reactions to products containing ingredients derived from algae or seaweed due to shared allergenic proteins.
- Algae and seaweed can contain proteins similar to those found in shellfish.
- Always inquire about allergies during client consultation.
- Avoid marine-derived ingredients for clients with shellfish allergies.
Memory trick: Be aware of the sea's hidden ties; shellfish allergies can surprise with algae.
