I used this serum every single morning for a month. No cheating.
The real test? Seeing if my post-acne scars would actually budge — or if I was just paying for fancy orange water.
It’s Sunday Riley‘s C.E.O. 15% Vitamin C Brightening Serum. $85. They claim “glowing, even-toned skin in 2 weeks.” Bold.
THD Ascorbate
A stable, oil-soluble form of vitamin C that doesn’t oxidize into useless brown goop in a month.
15% Concentration
Potent enough to do something, supposedly without the typical sting.
Brightening Complex
A mix of ingredients meant to tackle dark spots, not just general glow.

It’s not just vitamin C floating alone. The formula is built to keep it stable and help it penetrate. The hero is THD Ascorbate, but the supporting cast matters.
- THD Ascorbate (15%): Oil-soluble, stable vitamin C derivative
- Squalane: Hydration that doesn’t feel greasy
- Alpha Hydroxy Acids (Glycolic/Lactic): Gentle surface exfoliation
- Ginseng Root Extract: Antioxidant boost to fight daily damage
Texture is weird — a silky, dry oil that absorbs in under 15 seconds. Zero residue. Smells like a faint, earthy orange peel, not a candy factory.
Week 3 surprise: My makeup sat better. No pilling. But I also got two tiny, stubborn whiteheads along my jaw — a common protest from vitamin C.
My skin looked more awake by 10 AM. One specific sunspot faded maybe 30%. But my deeper acne scars? Barely moved. The glow is real, the scar-erasing was overpromised.
It’s a beautifully engineered product that delivers a reliable morning glow. But it’s not a miracle worker for serious pigmentation.
