I used this wrong for a week and looked like a blotchy mess. Vitamin C in the AM, fading acids at PM — flip it and your skin throws a tantrum.
The serum packs both ascorbic acid and azelaic acid derivative. That combo turns into a greasy, pilling disaster if you layer it under sunscreen wrong.
Prequel calls this a “fading serum” — $28 for 1 oz. The claim that got me: “visible dark spot reduction in 4 weeks.” Bold for a drugstore price point.
15% Vitamin C (THD ascorbate)
Stable form, not the stinging L-ascorbic — so no orange face by noon.
Azelaic acid derivative
Gentler than straight azelaic but still fades post-acne marks like a pro.
Kojic acid + licorice root
The backup dancers that actually pull their weight.

No fragrance, no drying alcohols — shocking for a brightener under $30. The THD ascorbate plays nice with niacinamide so you don’t have to choose.
- THD Ascorbate: Brightens without the sting of L-ascorbic acid
- Azelaic Acid Derivative: Fades red marks without the itch
- Kojic Acid: Blocks melanin production at the source
- Licorice Root Extract: Calms inflammation while fading

Watery-gel texture — sinks in under 20 seconds. Smells faintly of… nothing really. That’s a win in my book.
Week 2 I noticed my post-pimple marks faded noticeably faster. Week 3 my forehead looked less like a contour map. Unexpected: it actually helped my texture, not just tone.

Dark spots from old breakouts? 60% lighter after 4 weeks. My melasma patches? Still there but less angry. Pores looked smaller — didn’t expect that.

Keep it in your AM routine if you want brightening, PM if you want fading. I use it mornings and save my retinols for night — zero conflict.
