Detailed answer

Patch testing is an important step in ensuring the product is safe and suitable for your skin. It involves applying a small amount of the product on a small area of your skin, usually on the inner forearm, and monitoring for any adverse reactions. This helps to identify potential allergies, sensitivities, or irritations before using the product on your face or body. It is especially crucial for individuals with sensitive skin or a history of allergies. If any redness, itching, swelling, or other signs of a reaction occur during the patch test, it is best to avoid using the product to prevent further damage to your skin.
