Photoallergic Reaction
Definition: A photoallergic reaction happens when the skin becomes hypersensitive to sunlight after being exposed to certain chemicals, resulting in redness, swelling, and blisters.
Cause: Triggered by sunscreen ingredients, medications, or fragrances that react with UV rays.
Types:
- Delayed reaction: Symptoms typically appear 24-72 hours after sun exposure.
Protection Before the Cause: - Patch-test new products to identify any photosensitizing ingredients.
- Avoid the sun after using products known to cause sensitivity.
Cure After the Cause: - Apply anti-inflammatory creams like corticosteroids.
- Avoid further sun exposure and discontinue the use of triggering products.
Conclusion: Photoallergic reactions are preventable with proper product knowledge, and can be managed with medical treatment if symptoms appear.
