You know that feeling when you put on vitamin C and it pills into little rubbery balls by 10am? Yeah, this one doesn’t. I’m in DC humidity where my skin drinks serum then immediately sweats it off — but Prequel’s Gleam actually stays put. Like, sinks in within 15 seconds and doesn’t move. The real win? Those little sunspots on my cheekbones from last summer’s “I’ll reapply later” era? They’re fading. No sting. No orange tint. Just… gone.

💧 **What You’re Actually Buying**
It’s a 15% ethyl ascorbic acid serum — $28 for 1 oz. That’s the stable form of vitamin C that doesn’t oxidize in two weeks. I bought it because the brand’s whole thing is “dermatologist-formulated but not bougie.” No fragrance, no essential oils, no nonsense.
1. **10-Second Absorption** — Pat it in and you’re done. No waiting around before sunscreen.
2. **Zero Pilling** — Even under mineral SPF. Even in 90% humidity. Tested it.
3. **Glass Bottle That Doesn’t Suck** — Dropper actually works. No air exposure. Stays clear for months.

🧴 **Ingredients That Actually Do Something**
The formula is weirdly smart. Ethyl ascorbic acid at 15% is the star — it’s the gentler, more stable cousin of L-ascorbic that actually penetrates. Then they threw in ferulic acid (that’s the booster that makes vitamin C work harder) and niacinamide (calms the redness that other serums cause). No vitamin E, which I actually don’t miss — it always breaks me out.
– Ethyl Ascorbic Acid: Brightens without burning
– Ferulic Acid: Doubles antioxidant protection
– Niacinamide: Keeps irritation away
– Glycerin: So your face doesn’t feel tight

🌿 **How It Actually Feels On**
It’s watery. Like, almost toner-thin. First drop slides right off your finger if you’re not ready. But once it hits skin — whoosh — gone. No tacky residue. No film. Just slightly bouncier skin immediately. The smell? Nothing. That’s the point.
Two weeks in, I noticed something weird: my T-zone stopped getting shiny by noon. I think the niacinamide is doing heavy lifting. Also, no purging. Which for a 15% vitamin C is almost suspicious.
💡 **One Thing** Apply to damp skin, not dry. One pump, press in with palms. Dry skin makes it absorb too fast and you lose spreadability.

🔬 **What Actually Changed**
After 6 weeks: my post-inflammatory marks from old breakouts are about 60% lighter. The two sunspots on my left cheekbone are visibly smaller — not gone, but like someone took a white eraser to them. No new breakouts. No orange cast (looking at you, every other vitamin C). What didn’t change: my fine lines. But I didn’t expect that from a serum anyway.
✅ **Buy if** you have combination or oily skin in humid weather and want antioxidant protection without feeling like you’re wearing glue.
⏭️ **Skip if** you have super dry or compromised barrier — the watery texture might not be hydrating enough alone.
💰 **Worth it?** For $28, yes. It performs like a $65 serum. Just buy it direct so you get the fresh batch.

📅 **Final Call**
This is the summer serum I’ll repurchase until they stop making it. It does the one thing vitamin C should do — protect and brighten — without drama, smell, or a 10-step wait time.
**8.5/10** — Best humidity-proof vitamin C I’ve found
🛍️ **Where to Buy** Get it direct from Prequel’s site — they ship fast and sometimes include a mini cleanser sample. Don’t bother with Amazon; counterfeits are already popping up.
