The 24-hour patch test

Last updated October 12, 2026.

Before your first ritual

For external use only. Avoid contact with eyes. Patch test before first use. Do not apply to broken or irritated skin. If you have known ingredient allergies or a skin condition, consult a qualified clinician before use.

01 / Choose a small area

Wash and dry a small patch of intact skin on the inner arm. Use only a very small amount of the oil. Do not test near your eyes.

02 / Apply and wait

Apply a thin film and leave the area uncovered. Wait 24 hours before wider use. Avoid rubbing or repeatedly reapplying to the test area.

03 / Check your skin

Watch for redness, itching, swelling, burning, or other discomfort. If irritation occurs, wash the product off gently and discontinue use. Seek medical advice if symptoms persist, are severe or suggest an allergic reaction.

04 / Begin slowly

If no reaction occurs, start with a small amount. A negative patch test does not guarantee that a reaction cannot occur later. Stop use if irritation develops. Keep out of reach of children.
