**Subject:** This serum is a night-only diva (and that’s a good thing)

1.🌅Your skin works the night shift

Your microbiome doesn’t clock out at 9 PM — it actually starts its real job when you sleep. Repair, rebuild, party for your pores.

Slap this on in the morning and you’re wasting $98. The probiotics need darkness and downtime. AM application = throwing a rave at sunrise.

2.🌙What’s in the bottle?

Avant Pro-Biome Night Serum. $98 for 30ml. The claim that got me: “rebalances your skin’s ecosystem while you sleep.” Sounded like a wellness cult. I bit.

1

Probiotic ferment complex

Smells like sour yogurt but in a chic way — live bacteria that actually survive the bottle.

2

Squalane base

Not oily. Not sticky. Disappears in 11 seconds flat — I timed it.

3

Bakuchiol instead of retinol

No purge, no peel, no crying in the bathroom mirror.

3.🧪Ingredients that earn their spot

Three things doing the heavy lifting here. No filler, no fairy dust. The ferment is the star — it feeds your good bacteria and tells the bad ones to shut up.

  • Lactobacillus Ferment: Calms inflammation without stripping your barrier
  • Squalane: Mimics your skin’s natural oils — zero greasy residue
  • Bakuchiol: Plant-based retinol alternative that actually firms
  • Niacinamide: Pore minimizer that doesn’t burn
4.🛌Textures and truths

Gel-cream hybrid. Slides like cold butter on warm bread. Sinks in before you finish blinking. No tacky film — I can sleep on my side without peeling my face off the pillow.

Week two: my chin acne stopped texting me. Week three: woke up with that “did I just sleep 10 hours” glow. I slept 6. The serum lied for me.

💡

One Thing: Apply to slightly damp skin — wet micro biome absorbs the ferment 3x faster. Pat, don’t rub.
5.☀️Morning after reality check

Redness dropped 40%. Pores? Still there but smaller — like they went on a diet. Oil production normalized. Not a miracle, but close enough for a Tuesday.

Worth it?
For the price, yes — if you use it right. One drop = full face. Bottle lasts 3 months.
6.📅The only routine that works

PM only. Damp skin. No retinol stacking. That’s the whole secret. This serum is a high-maintenance friend — but she’ll change your skin if you respect her schedule.
