mixsoon - Master Serum 30ml

mixsoon Master Serum — bifida, hyaluronic acid and cica in one step

This serum's barrier-strengthening capabilities come courtesy of a formula rich in bifida ferment extract, hyaluronic acid and cica extract. Panthenol and sodium hyaluronate further amp up moisture levels. The serum is dermatologically tested to be suitable for sensitive skin. This is the mini size.

Three actives, one bottle

Most of the mixsoon range gives you one hero per product — which is excellent when you know exactly what you want, and awkward when you want ferment, calming and hydration all at once and do not fancy buying three bottles to get there.

That is what this is. A barrier repair serum that covers the ferment, the cica and the water in a single step. If you would rather run each active separately, Premium Bifida Serum is the barrier one and Soondy Centella Essence is the calming one.

30ml or 60ml?

This is the mini size, and it is the right first buy. mixsoon's own advice is to introduce one product at a time — which only works if you can find out cheaply whether your skin wants it. The 60ml is the same formula for when the answer is already yes.

Where it fits

After toner, before cream. It sits happily over Bifida Toner or Centella Toner, and under any cream you already own.

Frequently asked questions

Is the mixsoon Master Serum good for sensitive skin?
It is dermatologically tested to be suitable for sensitive skin, and the cica and panthenol are there for comfort.

What is bifida ferment extract?
A ferment from bifidobacteria — the family you would recognise from a yoghurt label — and a long-standing choice in barrier-focused Korean skincare.

30ml or 60ml?
Same formula. 30ml to find out whether it suits you; 60ml once you know.

Do I need a cream over it?
Yes. An unsealed serum evaporates within hours.
