Sunday Riley C.E.O. 15% Vitamin C Brightening Serum: Quick Review
Key actives:
THD Ascorbate (15% Vitamin C): Oil-soluble, stable form of vitamin C that is used to brighten skin, fade dark spots, and provide antioxidant support. Expect gradual spot and tone improvement (derivative ≠ L-ascorbic speed)
Phytosterols: Plant-based compounds that help soothe and support barrier function during active treatment.
15% Vitamin C Brightening Serum
Sunday Riley's C.E.O. 15% Vitamin C Brightening Serum is a potent antioxidant treatment featuring a high concentration of THD ascorbate (a stable vitamin C derivative) with squalane and phytosterols, designed to brighten, even skin tone, and address early signs of aging. Fragranced with citrus essential oils.
Who should use
Normal to oily skin types dealing with uneven skin tone, hyperpigmentation, minor fine lines, and dullness who want a multi-tasking antioxidant serum. Ideal for those comfortable with active ingredients and who already have a solid hydrating moisturizer in their routine to follow up. Dry skin types can use this product too! It’s an emulsion with squalane and humectants, so you should be safe. Still, follow with a moisturizer right after.
Who shouldn't use
Highly fragrance-sensitive users or those needing maximum-speed brightening (consider an L-ascorbic/ferulic formula); for deeper wrinkles, prioritize a retinoid at night.
Red Flags:
Contains essential oils (including citrus oils) that provide the signature scent but can irritate sensitive skin or cause photosensitivity.
Supporting ingredients worth noting:
Saccharide Isomerate: Plant-derived humectant that attempts to offset dryness.
Glycerin: Basic humectant for moisture retention.
Squalane (3rd) — lightweight emollient for slip and comfort; helps counter dryness.
