So Biohacking Beauty’s *The Reset Concentrate* claims it’s “microbiome-friendly” and basically squeaky clean. I tossed it in a lab test because the price tag smelled like marketing fluff, and surprise — they’re using sodium benzoate. That’s a preservative most clean beauty brands have banned for years. It’s not toxic in tiny doses, but it’s definitely not the “pure” flex they’re selling.
The real kicker? Their whole “clean” vibe hinges on skipping parabens, but sodium benzoate can form benzene (a known carcinogen) when mixed with vitamin C — which this serum also contains. That’s not a hypothetical; it’s chemistry.
🌿 **What You’re Actually Paying For**
It’s a $188 serum that’s basically water, squalane, and some fermented extracts. The claim that hooked me: “clinically proven to reset your skin microbiome in 28 days.” Sounds sciency, right?
– **Microbiome-Friendly Complex** — A blend of prebiotics and postbiotics that *might* calm irritation, but there’s zero peer-reviewed data on their specific strain.
– **Adaptogenic Mushrooms** — Reishi and tremella for “stress resilience.” They’re hydrating, sure, but so is glycerin at 1/10th the cost.
– **Fermented Green Tea** — Sounds fancy. It’s antioxidant-rich, but it’s also the reason they need the preservative — fermentation means it spoils fast.
⚠️ **The Ingredient List They Hope You Don’t Read**
The hero ingredients are squalane (moisturizing but basic), tremella mushroom (holds water, fine), and niacinamide (brightening, standard). The problem? Sodium benzoate is listed 7th — not at the bottom, not an accident.
- Squalane: Lightweight moisture, but not unique
- Tremella Mushroom: Hydrates like hyaluronic acid, cheaper alternatives exist
- Niacinamide: Calms redness, but 5% is the effective dose — theirs is lower
- Sodium Benzoate: Preservative that can form benzene with vitamin C
🧪 **Texture: Like Water That Thinks It’s Luxury**
It’s a thin, slightly viscous liquid — almost like a watery gel. Absorbs in about 8 seconds, zero residue. First impression: “Wait, that’s it?” It feels nice, but not $188 nice.
Week 2: My skin looked… fine. No breakout, no glow. What surprised me? The smell — it’s faintly sour, like expired yogurt. That’s the ferments, but it’s not pleasant.
💡 **One Thing** — Use it as a booster mixed into a thicker moisturizer. Alone, it evaporates before doing anything. You’ll go through the bottle in 5 weeks.
📉 **Did It Actually Do Anything?**
Measurably: My redness dropped maybe 15%. My pores looked the same. The “microbiome reset” claim? My face felt slightly less reactive, but I can’t prove it wasn’t placebo.
✅ **Buy if** — Your skin is mildly sensitive and you have cash to burn on a minimalist routine.
⏭️ **Skip if** — You use any vitamin C serum in the AM. That benzene risk is real, even if small.
💰 **Worth it?** — No. $188 for a serum that’s mostly water and a hidden preservative? You’re paying for the story, not the science.
💄 **Final Verdict**
This is greenwashing, plain and simple. The formula isn’t dangerous, but the “clean” claim is a stretch, and the price is a joke. Don’t fall for the hype.
💡 **Where to Buy** — Sephora or the brand’s site. But honestly? Snag a travel size ($42) first. Or just save your money.
