Mara’s $92 serum screams “clean” on the bottle, but flip it over and there’s phenoxyethanol — a synthetic preservative that’s about as “natural” as a plastic apple. It’s not toxic, but it’s the cosmetic industry’s favorite loophole for the word “clean.”
Here’s the kicker: the formula is 85% algae, yet it still needs lab-made stabilizers to survive your bathroom shelf. That’s not a crime — it’s just marketing math.
It’s a watery-gel serum with cold-pressed algae, vitamin C (from sea buckthorn), and enzymes. The pitch: “skin superfood” that brightens without irritation. I bought it because the texture looked like nothing I’d tried — and I’m a sucker for a marine theme.
Algae Base
Feels like ocean water in a bottle — 85% of it is fermented plankton, which sounds gross but smells like a spa.
Vitamin C Source
Not ascorbic acid. It’s sea buckthorn — gentler, but slower to fade spots. Think slow cooker, not microwave.
Enzyme Complex
Papaya and pineapple extracts that dissolve dead skin — but they’re so mild, you might forget they’re there.

It’s not dirty, but it’s not the “100% pure” vibe the label suggests. The hero ingredients do real work, but the preservative blend is the adult in the room keeping it stable. You’re paying for premium algae, not magic.
- Algae Ferment: Hydrates and calms redness — the real star
- Sea Buckthorn: Slow-release vitamin C that brightens over weeks
- Phenoxyethanol: Synthetic preservative — safe but not ‘natural’
- Papain Enzyme: Gentle exfoliant that smooths texture

It’s like water that turned into silk. Absorbs in 10 seconds flat, zero stickiness — I could layer it under sunscreen without pilling. The scent is faintly oceanic, not perfumey, which I appreciated at 7am.
Week two: my forehead’s rough patches got smoother, but my dark spots? Still there. The glow is real, but it’s a “subtle lit-from-within” — not a “whoa did you get a facial?” effect. Also, it’s drying if you skip moisturizer. Don’t skip moisturizer.

After three weeks, my skin looks more rested and less blotchy. The glow is even, but the vitamin C isn’t strong enough to erase real pigmentation. It’s a maintenance serum, not a treatment.

It’s a luxurious, well-made serum that’s “clean” only in the loosest sense. I’d repurchase — but only when it’s on sale, and only because I’m a texture junkie.
