If you have really sensitive skin, you might like to patch test before using the product, try a patch test to make sure you won’t get an unwanted reaction:
Wash and dry a small area of your upper arm (such as the crook of your elbow).
Apply a small amount of product. Cover the spot with a bandage or band aid and leave it in place for 24 hours, being careful not to get the bandage/band aid wet.
If any redness, burning, itching, or other irritation occurs, you can assume you’re sensitive to the product and shouldn’t use it. If you have a reaction, remove the bandage immediately and wash the spot with soap and water.
If you don’t see or feel any reaction, then the product is probably safe to use.
