Morning or night? I tested this on both sides of my sink for three weeks so you don’t have to guess.
The real answer depends on one thing: whether your skin can handle antioxidants AND probiotics at 7am without freaking out. Mine did fine — but my friend’s reactive skin said absolutely not.
It’s a $26 serum from Mary&May that claims to combine idebenone (a stabler cousin of CoQ10) with bifida ferment lysate — that probiotic extract Korean skincare loves for barrier repair. The claim that got me: “works harder than vitamin C without the irritation.” Bold.
Biome Complex
Bifida + lactobacillus ferment — sounds gross, but it calms redness like nothing else
Idebenone 500ppm
Stronger antioxidant than vitamin E, but way more stable in light — hence the AM debate
Panthenol + Madecassoside
Two soothing agents that make this feel like a hug for irritated skin

The formula is clean but not boring. Idebenone works at 500ppm — enough to fight pollution and blue light damage without the sting of high-concentration actives. Bifida lysate is the real star here; it strengthens your microbiome so your skin stops overreacting to everything.
- Idebenone: 5x more stable than CoQ10 in light
- Bifida Ferment Lysate: Strengthens skin’s natural defense barrier
- Panthenol: Locks in moisture without clogging
- Madecassoside: Heals micro-inflammation you can’t even see
It’s a watery gel that disappears in 12 seconds flat. No sticky residue, no white cast, no pilling under sunscreen. First impression: “Is this even doing anything?”
Week 2: my forehead texture started smoothing out. Week 3: my post-acne marks faded faster than usual. The weird part? I didn’t notice until I stopped using it for two days and my skin looked dull again.
My redness dropped about 40% by week 3. Pores looked tighter — not smaller, but less noticeable. What didn’t change: my dark circles (no serum fixes those) and my hormonal chin breakout still showed up on schedule.
Use it AM if your skin can handle it — the antioxidant protection is real and the texture disappears under makeup. PM if your skin is reactive or you’re already using actives in the morning. Either way, it’s a solid everyday serum that won’t fight your other products.
