1.💎The $20 Vitamin C That Hits

Okay, I bought this on a whim because my $90 serum ran out and I’m petty. I did not expect to be texting you about it at 11pm.

But here we are. This thing has more vitamin C punch than stuff three times the price, and it doesn’t turn your face into a sticky flytrap.

2.🔬What You’re Actually Buying

Derma E sent us this for lab testing, which I usually roll my eyes at. But the results came back and I had to double-check the price tag.

1

THD Ascorbate

It’s a stable, oil-soluble C that actually penetrates — not the cheap ascorbic acid that oxidizes in your bathroom cabinet.

2

Hyaluronic Acid Base

Plumps without that weird tacky film. My makeup goes on smoother than it did with my expensive stuff.

3

No Staining

The formula is slightly yellow but dries clear. You won’t look like a Simpsons character.

3.🧴Inside the Bottle

The ingredient list reads like a skincare nerd’s fantasy, but it doesn’t feel heavy. It’s actually lighter than most gel moisturizers I own.

The star is the THD ascorbate, which is the gentler cousin of pure vitamin C. It does the brightening job without the redness and irritation that makes you look like you just ran a marathon.

  • Vitamin C (THD): Fades dark spots without the sting
  • Hyaluronic Acid: Draws in moisture so your skin looks juicy, not dry
  • Vitamin E: Stops the C from going bad too fast
  • Licorice Root Extract: Calms redness and evens tone

4.📊Texture & The Reality Check

It’s a slightly viscous liquid that sinks in about 15 seconds. No residue on my fingers, no weird shine. Smells faintly citrusy — not like a candle.

Two weeks in, the dark spot on my left cheek from that breakout in January is noticeably lighter. Not gone, but lighter. The price makes me want to cry about all the money I wasted before.

💡

One Thing: Use it on damp skin. Like, immediately after toner. It spreads twice as far and absorbs faster. You’ll use half the product.

5.💸The Real Results

My skin looks brighter in the morning, especially around my nose where I get that dull look. The dark spot faded about 40% in 3 weeks. My forehead lines look slightly less… angry?

It didn’t do anything for my pores, which I didn’t expect it to. It’s a glow serum, not a miracle worker.

Buy if
You have dull, tired skin or sun spots and don’t want to spend $80+ on a name brand.
⏭️

Skip if
You have super sensitive skin that reacts to any active ingredient. This is gentle, but not that gentle.
💰

Worth it?
Absolutely. It does what my $90 serum did for a quarter of the price.
