Why it comes as a powder

Stem cell culture medium loses stability over time once it is in liquid. Freeze-drying removes the water and preserves the active content until you are ready to use it, so every vial you mix is at full strength. ByTheQuality's freeze-drying method was recognised with Korea's IR52 Jang Young-Shil Award from the Ministry of Science and ICT.

How to use

1. Remove the caps from one powder vial (5ml) and one liquid vial (7ml).
2. Pour the liquid into the powder vial. Swirl gently until fully dissolved and clear. Do not shake hard.
3. Apply to clean skin after toner, morning and night. Tap in until absorbed, then follow with moisturiser.
4. For best results, use straight after a Crown MTS session. Apply section by section as you work across the face so the skin stays wet.
5. Use the mixed vial within 1 to 2 weeks. Keep it capped, cool and out of sunlight between uses.

Frequently asked questions

What is an exosome?
Exosomes are tiny vesicles that cells release to carry signals (proteins, lipids, genetic material) to other cells. In skincare they are used to deliver those signals to skin cells. EXO 15698 combines exosomes from four sources: human stem cell culture medium, milk, salmon and Centella asiatica.

How is this different from Cellonic Booster?
Cellonic Booster is stem cell conditioned media on its own. EXO 15698 adds three further exosome sources on top of the culture medium and is freeze-dried for stability. It is the stronger, more expensive option, which is why we call it the most powerful ampoule in the store.

Do I need MTS to use it?
No. It works as a daily ampoule. The 28.33% skin density result was measured with MTS, and that is the pairing ByTheQuality recommends, but you will still see benefit without it.

Can I mix Hyal Alpha into it?
Yes. Once EXO 15698 is mixed, you can pour it into a Hyal Alpha vial to add three-weight hyaluronic acid for extra hydration.

Why is there a pre-order notice?
Demand is high and ByTheQuality produces in small batches. It is currently sold out, so we are taking pre-orders and will send out as soon as possible.

Before & After

Detailed Description

Main Ingredients

• Human stem cell culture medium (including human amniotic fluid stem cell culture medium)
• Milk exosomes
• Salmon testicle exosomes
• Centella asiatica callus extracellular vesicles (plant-based exosomes)

Note: Human stem cell culture extract may lose stability over time in solution; therefore, freeze-drying is recommended. This scientific advancement was recognized with Korea's prestigious IR52 Jang Young-Shil Award by the Ministry of Science and ICT. With a 200mg powder weight containing 300,000 ppm, this composition is key to clinical efficacy.
