1.😮‍💨Finally, A Serum That Gets It

My skin stopped screaming after three days. Not exaggerating.

Most “calming” serums are full of bullshit — essential oils that burn and fancy extracts that do nothing. This one just… works. Quietly. No fanfare.

2.💰What You’re Actually Paying For

It’s $28 for 1 oz. Stratia claims it repairs your moisture barrier and calms redness at the same time. I rolled my eyes. Then I tried it.

1

pH 5.5 Formula

Your skin’s natural happy place. Most peptides sit higher and sting. This one doesn’t.

2

Copper Peptide Complex

The expensive stuff that actually signals collagen — without the usual irritation.

3

No Fillers

No fragrance, no alcohol, no essential oils. Just the goods.

3.🧪The Ingredient Shortlist

Three heroes, no chorus of useless botanicals. The copper peptides do the heavy lifting while niacinamide calms the redness down. Matrixyl 3000 is the quiet overachiever.

  • Copper Tripeptide-1: Repairs skin without the burn
  • Niacinamide: Reduces redness + pores shrink visibly
  • Matrixyl 3000: Plumps fine lines without irritation
  • Glycerin: The only humectant — simple, effective

4.💧Texture & The First Week

Watery-gel. Sinks in about 12 seconds flat. No tacky residue, no waiting around before moisturizer.

Week two hit and I noticed something weird — my cheeks stopped flushing after hot showers. That never happens. Even my sunscreen started stinging less.

💡

One Thing: Apply to damp skin. Not dry. Two drops on wet face spreads further and absorbs faster — trust me.

5.📊The Honest Results

Redness dropped maybe 40% by week three. Not gone — but the angry flush is way quieter. Fine lines? Slightly softer. Not Botox, just… better.
