Who is this range suited for?
Rich Serums are suitable for people with sensitive or reactive skin who want gentle, everyday hydration rather than high-strength treatments. They're a good fit if you prefer balanced formulations over maximum-potency actives, value comfortable, elegant textures, and want a simple routine without needing to research ingredient compatibility or pH levels.
How comfortable are they to wear daily?
They're designed to feel comfortable, not just to perform. The serums absorb quickly, feel lightweight rather than heavy or sticky, and layer well under moisturiser, sunscreen, and makeup without pilling. A product that's pleasant to use every day tends to deliver better results over time than a stronger one that's uncomfortable to stick with, making the Rich Serum range a great addition to thoughtful skincare routines
Why don't MUJI's Rich Serums use the highest possible concentrations of active ingredients?
MUJI prioritises tolerability over potency. Rather than maximising active ingredient strength, the formulas pair effective ingredients with moisturising and soothing components that support the skin barrier and reduce the risk of irritation. This makes them a good fit if you're new to ingredients like retinoids or vitamin C, have sensitive or easily irritated skin, or want to use active ingredients consistently without redness, dryness, or peeling.
