PATCH TEST INSTRUCTIONS: Although we have done our best to ensure our products are free from common skin irritants, we would encourage you to perform a patch test: To ensure compatibility, please patch test our products before regular use. To perform a patch test, apply a small amount of the product on the inside of your wrist or the crook of your elbow. Leave for 24-48 hours without washing. Watch for signs of a reaction, such as redness, a rash, itchiness, etc. If no reaction occurs, the product may be suitable for regular use. However, please discontinue use if any reaction occurs, as sometimes the location or concentration of a product can trigger varying reactions.
