It can be used as a daily brightening step even when your skin already looks fairly balanced. Whether you need it depends on your routine and the concerns you want to address.

The formula is the same Vitamin C Brightening Serum; the difference is in how it's used. This collection is framed around everyday maintenance for skin that's already balanced. If dullness or a tired-looking complexion is your main concern, see the Vitamin C Serum for Dull Skin collection instead.

Apply after cleansing and toner, both morning and night, and follow with moisturizer. In the morning, finish with sunscreen.
