Two safeguards: skin-friendly acidity + gentle buffering

 

In 2013, the Nobel Prize in Physiology or Medicine decoded the cell’s “vesicle trafficking” rules—how cells package and deliver signals. That blueprint helps us steer exosome formation and release, opening new possibilities for skin and aesthetics. Exosomes are widely viewed as one of this century’s most promising paths past regeneration/repair bottlenecks.

TL;DR

 

 

• We use a mildly acidic, skin-friendly pH system (aligned with the skin’s acid mantle) and a gentle buffer to help keep pH and osmolality stable for ~48 h after reconstitution.

• Every lot undergoes irritation screening and microbial limits testing. Still, individual tolerance varies—please patch-test first if you’re sensitive.

• First 72 h post-procedure: keep it simple—fresh-mix exosomes → 10–15 min calming mask → barrier cream → broad-spectrum/physical SPF. Stagger strong acids/retinoids/high-dose L-AA vitamin C.

Why “mildly acidic + buffered” matters

 

 

• Skin is naturally acidic. Healthy stratum corneum sits in a mildly acidic range; drifting too high or low can nudge the barrier off balance.

• Buffer ≠ one number. Our dedicated diluent uses a soft buffer pair so the reconstituted solution resists pH swings from air/temperature over its 48-hour use window—helping reduce prickling and tightness.

• Osmolality counts. An isosmotic environment further lowers the chance of sting.

• Format: EXO-Lyospheres™ freeze-dried exosome powder + dedicated diluent; one vial = one session, fresh-mixed right before use. If you must split: refrigerate 2–8 °C and finish within 48 h.

“Will it sting?” — the honest answer

 

 

• What we control: pH, osmolality, and avoiding unnecessary high-sting solvents/strong fragrance (see Q25); plus irritation evaluation and micro limits before batch release.

• What no brand can guarantee: your barrier status, recent procedures/peels, and whether instructions are followed. No one can promise zero reaction for every individual.

• So please: patch-test 24–48 h (behind ear/inner forearm) before first full-face use, and follow the 72-hour rule after procedures.

Playing nicely with other actives

 

Partner	How to pair	Why
AHA/BHA/strong exfoliants	Stagger by day/week; avoid in first 72 h	Low-pH acids + procedure window = higher sting risk
High-dose L-ascorbic acid (vit C)	Re-introduce ≥ D4–D7, split timing (e.g., AM vit C / PM exosomes)	pH + irritation stacking
Retinoids (retinol/retinal, Rx tretinoin)	Finish one exosome mini-cycle first or alternate nights	Lowers barrier volatility/redness
Peptides / ceramides / squalane	Compatible immediately (especially within the first 72 h)	Repair synergy, low irritation

If you feel tingling/redness—how to read it

 

 

• Brief (≤10 min) tingling/light flush on D0: common post-procedure; usually settles after the 10–15 min calming mask.

• Persistent burning/large red patches/oozing: stop immediately; switch to saline mist + barrier cream, avoid heat/sun; contact a professional.

• Keep records: LOT/Vial-ID, time of use, photos—helps with traceability and support.

Patch test (must-do for sensitive skin)

 

 

• On clean, dry skin behind the ear/inner forearm, apply a pea-sized amount of the fresh-mixed solution over a coin-sized area.

• Observe 24–48 h. Mild transient pinkness is usually fine; discontinue and consult if burning, persistent redness, papules/oozing, or intense itch appears.

72-hour “low-irritation” checklist

 

 

• D0 (procedure day): fresh-mix and apply within 0–60 min → calming mask 10–15 min → light barrier cream → broad-spectrum/physical SPF. No makeup (see Q14).

• D1–D3: keep thin layers + repair; avoid strong acids/retinoids/high-dose L-AA, hot steam/sauna, and heavy workouts.

• ≥ D4–D7: reintroduce actives gradually based on tolerance; continue 7–10 days/visit cadence for your next session.

How we bake “minimal sting” into QC

 

 

• Formulation: mildly acidic skin-friendly pH, gentle buffer, isosmotic diluent; avoid unnecessary high-ethanol and heavy perfume systems.

• Release testing: microbial limits, key physico-chemical specs, visual clarity—only released if compliant.

• Delivery: Fresh-Batch 48h—newest released lot assigned within 48 h of order; per-vial label & temp-controlled ship. Each vial has LOT / Vial-ID / QR to the Trace Page (COA snapshot, temp history, usage notes).

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. We use a skin-friendly mildly acidic pH and conduct irritation/micro limits testing, but individual responses vary. Sensitive users should patch-test and follow professional guidance.

One-line wrap

 

We keep the formula in skin’s comfort zone—mildly acidic, buffered, isosmotic—then cut variables with freeze-dry freshness, single-use dosing, and a 48-hour use window. The rest is about 72 hours of patience and clean execution—that’s how soothing and stability add up.
