Ingredient caution: alpha arbutin, kojic acid, licorice extract might cause tingling, dryness or redness in sensitive skin; fragrance, essential oils or fragrance allergens might trigger redness, itching or allergic irritation; UV filters might sting around the eyes or irritate very sensitive skin; humectants such as hyaluronic acid/glycerin are usually gentle but might feel sticky or tight if not sealed with moisturiser. Do a patch test before applying. First-time users should start 3–4 times a week and pair with sunscreen, because pigmentation care works best with UV protection. Avoid this product if you have fragrance allergy, eczema-prone skin or a damaged barrier. Patch test near the jawline first, avoid the eye corners, and remove gently at night. Apply on slightly damp skin and follow with moisturiser if dryness occurs. Stop use if irritation persists.
