Q28｜How do I store unopened product?

Aug 30, 20253 min read

Four rules:

shade | dry | cool | never freeze

2013’s Nobel Prize in Physiology or Medicine decoded cellular “vesicle trafficking.” That playbook underpins modern exosome handling—why a freeze-dried, fresh-mixed routine protects fragile actives and makes sense for skin use.

TL;DR

Follow the carton: store in a shaded, dry, cool place; do not freeze.
Keep items factory-sealed with all inserts/accessories. Expiry (EXP) follows the outer box.
We run Fresh-Batch 48h: the newest released lot is assigned within 48 hours, per-vial labels are printed, and orders ship temperature-controlled. Inspect packaging and seals on arrival.

01｜Two bottles, two temperaments

Lyophilized powder (moisture-sensitive)

Priorities: dry + dark.
Store at cool room temperature; don’t park it in steamy bathrooms.

Dedicated diluent (heat-sensitive)

Avoid heat spikes, direct sun, and temperature swings.
Keep upright with the cap firmly closed.

Unopened units: cool room storage is sufficient—no freezer required. In hot/humid regions, choose a ventilated, dry drawer or cabinet away from windows and heat sources.

02｜Home storage: six hard rules

Keep everything in the carton to limit light and humidity.
Avoid the three highs: high heat (sun/vents), high humidity (bathroom, near humidifiers), high light (window ledges).
Never freeze. Freezing/condensation can damage contents and packaging.
Don’t leave it in the car. Trunks and cabins swing from hot to cold.
Store upright, especially the diluent, to minimize leak risk.
Keep out of reach of children and pets.

03｜On delivery: 3 quick checks

Outer box: any moisture marks, crushing, or tears?
Vial seals: cap, tamper ring, foil/aluminum (if present) intact?
Labels: spec + production/expiry dates legible and match your order?

If anything seems off: photograph + note the LOT, then contact support.

04｜Travel & transport (summer heat / winter cold)

Carry-on > checked. Don’t leave in trunks; use a cushioned, light-shielding pouch.
Hot climates: avoid > 30 °C exposure. A non-freezing insulated pouch is fine in transit; return to cool, dry storage ASAP.
Cold climates: avoid near-freezing/icing. If it’s been chilled, let it warm to room temp before opening to reduce condensation.

05｜Common myths—fixed fast

Myth	Do this instead
“The fridge is always safer.”	Unopened: cool room storage is enough. Never freeze. In extreme heat, short-term refrigeration (2–8 °C) is OK—not the freezer and not the door shelf; prevent condensation.
“Bathroom storage is convenient.”	Bathrooms are humid + warm. Use a dry drawer/cabinet.
“A little sun won’t hurt.”	Direct sun raises temperature—always keep shaded.
“Pre-pour the diluent for later.”	Keep factory-sealed. Reconstitute only on the day you apply (see Q11).

06｜Before opening & reconstitution (see Q11/Q12)

Reconstitute only when needed; aim for one vial = one session.
If you must split: refrigerate 2–8 °C and finish within 48 h.
Mix gently: run diluent down the vial wall and invert lightly (don’t hard-shake).
Procedure day window: within 0–60 min of microneedling/device work → calming mask 10–15 min.
Same-day don’ts: makeup, strong acids, strong retinoids, high-dose L-AA vitamin C (see Q12, Q14).

07｜Labels & traceability (freshness on the label)

Every vial shows LOT / Vial-ID / spec / dates.
Fresh-Batch 48h ensures you receive the newest released lot.
Scan the QR to open the Trace Page with the batch COA snapshot, temperature history, and usage/storage tips.

Compliance footer (site-ready)

This is a cosmetic product for surface-level soothing, hydration, and barrier support. It does not diagnose, treat, cure, or prevent disease. Unopened storage: shade, dry, cool, never freeze. Expiry and lot information follow the outer box.

One-line wrap

Master the four basics—shade, dry, cool, never freeze—keep it sealed and traceable; when you’re ready, the fresh-mix, one-vial-per-session workflow delivers peak freshness under a clean, closed hygiene loop.
