What should I do if the gel causes redness or itching?

The product's cautions state: Stop using the gel if irritation appears. If you experience redness, itching, or a burning sensation, the first step is to wash the affected area gently with lukewarm water and a mild soap to remove any residue. Avoid scratching or applying other products to the area. Irritation is uncommon but possible, especially if you have very sensitive skin or are using the product on compromised skin (which the instructions advise against). It could be a reaction to a specific ingredient or fragrance. Allow your skin to calm down for a day or two. If symptoms persist or worsen, seek advice from a dermatologist or pharmacist. To prevent future reactions, you can perform a patch test by applying a small amount of gel to the inside of your elbow and waiting 24 hours before broader use.
