Old formula was fine. New formula is… better? They swapped the vitamin C derivative and added ferulic acid. The glow didn’t die — it got a little more aggressive.
The real move here? They killed the sticky finish. The old one sat on my skin like a tacky film. This one vanishes. That alone is the upgrade.
It’s a dark-spot serum with guava extract and a new vitamin C derivative (THD ascorbate) plus ferulic acid. $45 for 1 oz. The claim that made me roll my eyes: “brighter skin in 7 days.”
New Vitamin C Derivative
THD ascorbate is more stable and less irritating — your skin doesn’t freak out like with L-ascorbic acid.
Ferulic Acid Boost
Stabilizes the C and boosts antioxidant protection. Smart addition, not just marketing fluff.
Guava Extract
Smells like a tropical drink. Does it do anything? Honestly, it’s for the scent and marketing — but I’m not mad at it.

The old formula used ascorbyl glucoside — gentle but slow. THD ascorbate is faster, more potent. And ferulic acid? That’s the backbone of the best vitamin C serums on the market. They finally got the memo.
- THD Ascorbate: Oil-soluble C that penetrates deeper without stinging
- Ferulic Acid: Doubles the C’s effectiveness and fights UV damage
- Niacinamide: Fades spots and calms redness — always a good teammate
- Hyaluronic Acid: Keeps it hydrating so the C doesn’t dry you out

It’s a thin gel-serum. Absorbs in 10 seconds. No stickiness — thank god. First application: skin feels plump, slightly tacky for a second, then nothing. Dewy but not greasy. Smells like guava candy — borderline too sweet, but whatever.
Week 2: My post-acne marks are lighter. Not gone — lighter. The ferulic acid makes it tingle a little on broken skin. That’s normal. Unexpected thing: it plays terribly with thick moisturizers. Pills if you rush. Wait 60 seconds before layering.

After 3 weeks: dark spots are 30% lighter. New breakouts heal faster without leaving purple marks. But my overall glow? Same as the old formula. The ferulic acid is the real hero here — it prevented new spots from forming. That’s the win nobody talks about.

They fixed the texture, upgraded the ingredient, and kept the glow. It’s not a revolution — it’s a solid evolution. Buy it if you liked the old one. Skip if you hate fruity scents.
