Chaturbhuj Japani Oil is generally designed for external use and can suit a variety of skin types. However, if you have sensitive skin, it is advisable to perform a patch test first by applying a small amount on a less sensitive area, such as the inside of your wrist, and waiting 24 hours to check for any adverse reaction. If irritation occurs, discontinue use and consult a healthcare professional. Always consider consulting with a dermatologist before using new products on sensitive skin.
