🧪 How to Patch Test a Skincare Product

1. Choose a test area:

   • Best spots: behind your ear, along the jawline, or inner forearm

   • These areas mimic facial skin but are less visible if there’s a reaction.

2. Clean and dry the area:

   • Wash with gentle soap and water; pat dry.

3. Apply a small amount of the product:

   • Use a pea-sized amount or less.

   • Don’t rub it in aggressively.

4. Wait and observe:

   • Leave it on for 24 hours (or up to 72 hours for leave-on treatments).

   • Do not wash the area unless the product is a cleanser.

5. Watch for signs of a reaction:

   • Redness, itching, swelling, burning, bumps, or dryness = potential irritation or allergy.

6. No reaction? Good sign!

   • If there’s no visible or uncomfortable response, the product is likely safe to use on your face.

🚫 If You Experience Irritation:

• Wash the area with lukewarm water and apply a calming moisturizer.

• Consider consulting a dermatologist if the reaction is severe or persistent.
