Patch test instructions are below the video + make sure to place the plastic lid back on the bottle after usage.
To perform a patch test:
1. Cleanse the area where you will apply the patch test, typically on the inside the elbow but if you use strong skincare ingredients I’d recommend to apply it on your jawline.
2. Apply a small amount of the product to the patch test area (step 2 & step 3 and leave it on for 10 minutes and clean the area) and wait for 24 hours.
3. Observe the area for any redness, itching, or irritation. If there is no reaction, it is likely you can use the product safely.
