Sensory Review
We wore this CBD-infused Vitamin C serum through a heatwave—here’s how it actually feels on day 1 vs day 30.
Expert Analysis · Honest Reviews · Real Results
1.🔥Heatwave? My face said bet.

Day one was 94 degrees and my skin was already screaming before this serum touched it. I slapped it on expecting the usual sticky Vitamin C mess.

It sunk in before I could even finish my iced coffee. No film. No orange tint. That’s the moment I knew this wasn’t going to be a boring review.

2.🌿The CBD is the plot twist

It’s $48 for 1oz. The claim that got me? “CBD + Vitamin C for glow without irritation.” I’ve been burned by C serums before — literally, my cheeks hate L-ascorbic acid.

1

Watery-gel texture

Feels like a fancy toner, not a heavy oil — perfect for 6am when you can’t think.

2

Zero-pill finish

Layers under SPF without rolling off into little white balls. Rare.

3

Glass dropper

Heavy bottle. Doesn’t feel cheap. Does make my bathroom shelf look bougie.

3.🧪What’s actually inside

It’s not just Vitamin C — it’s a blend that actually respects your skin barrier. The sea buckthorn is the quiet MVP here, calming down the redness that usually comes with C.

  • THD Ascorbate: Stable Vitamin C that doesn’t oxidize in your bathroom cabinet
  • Sea Buckthorn: Omega-rich oil that calms redness fast
  • CBD Isolate: Anti-inflammatory that chills out reactive skin
  • Squalane: Lightweight hydration that doesn’t clog pores

4.🧊Day 1 vs Day 30: The real talk

Day 1: It’s got the slip of a light moisturizer. A little goes far — I used 4 drops and almost had too much. It’s cooling, like a facial mist that decided to work harder.

Week 2: My skin stopped feeling tight after washing my face. By day 30, my post-breakout red marks faded faster than usual. The weird part? My forehead texture — those tiny bumps — just… flattened. I wasn’t tracking that.

💡

One Thing: Press it in with your palms instead of rubbing. The heat activates the CBD and it absorbs twice as fast.

5.Did it actually work?

My hyperpigmentation is lighter — not gone, but visibly less angry. The glow is real but subtle, like “I slept 8 hours” not “I got a facial.” No breakouts, no irritation, no regrets.

Buy if
You have normal-to-dry skin that hates traditional C serums but still wants the brightening effect.
⏭️

Skip if
You’re oily AF and prefer gel-to-powder finishes — this leaves a slight dewy residue.
💰

Worth it?
Yes — but it’s a maintenance serum, not a miracle. You’ll notice the difference by week 3, not day 2.

6.📝Final call

It’s the most forgiving Vitamin C I’ve ever used. If you’ve given up on C serums because they sting or pill, this is your second chance.
