Is this product safe for sensitive skin, and do I need to perform a patch test?

Because this henna paste contains aromatic essential oils—specifically clove oil and eucalyptus leaf oil—it is classified as a cosmetic product with potential allergens. While henna itself is a natural plant pigment, the essential oils are added to help the paste adhere to the skin and encourage a deeper stain, but they can also trigger irritation in reactive skin types. It is wise to perform a patch test before applying the design to a larger area. Apply a small amount of the paste to a discreet spot on your inner arm and leave it for the recommended time. If you experience redness, itching, or burning, remove the product immediately and discontinue use. Avoid applying the paste to any areas of skin that are already irritated, damaged, or broken. Additionally, keep the product away from the eye area to prevent severe irritation. If you have a history of contact dermatitis or known allergies to essential oils, consult a specialist before use.
