Dry · 35-44 · Body and face, same consistency
Light texture, potent results
The Master Serum is one of those that feels weightless but delivers. My skin was noticeably bouncier after a month.

Normal · 18-24 · Basic student routine
No pilling under sunscreen
That was always my issue. Master Serum absorbs completely and I can layer SPF and foundation with nothing balling up.

Definitely reordering
Master Serum is a fixture in my kit. Mixsoon clearly knows what they're doing.

Sensitive · 25-34 · Short routine, few actives
Very good serum, needs a month
Master Serum works, but be patient. Four weeks in and my skin is more even and bright. Not overnight magic.

Didn't do what I hoped
A month with Master Serum and my skin is the same. Guess I need something else.
