Which is correct?Depending on your lifestyle, you can use this product both in the morning and at night. However, if you spend a lot of time outdoors, it is recommended to use it only in the evening. This is because the product can make your skin sensitive to the sun, and if not used correctly, it may increase the risk of hyperpigmentation. Can I pair this with additional brightening products, like Daily Skin Clarifier?Yes! Daily Skin Clarifier is a great choice for morning use as it contains antioxidants and natural brighteners. On the other hand, Brilliant Tone is the best for use in the evening. Using both products can help righten hyperpigmentation at a faster rate and maintain an even skin tone. Is this product safe for pregnant or nursing mothers?We recommend consulting with your physician before using active home care products if you are expecting or nursing.
