Best Sofina iP Products for Dry Skin
3 Sofina iP picks that actually work on dry skin — ranked by editor rating, not by what the brand pushes hardest. Updated 2026.
Sofina is the Kao Group's answer to SK-II and IPSA: dermatology-grade J-Beauty with a 40-year R&D lab behind it, priced in the premium-but-approachable middle. The iP Base Care Serum — a pre-toner "interpenetrating" essence — became a cult pick among Japanese women who wanted a single-shot booster without building a 10-step routine. Lower-hype than Shiseido, more formulated than Hada Labo.

8.9/10 · serumiP Base Care Serum
Kao's flagship Sofina iP serum — Japan's #1 selling serum for 4+ consecutive years and absolutely unique in the global skincare market. The pitch: a carbonated (CO2-infused) foam serum that uses the Bohr effect (raised tissue CO2 → increased oxygen delivery to skin cells) to boost microcirculation and skin glow. The texture is genuinely novel — it dispenses as a foaming sphere that liquefies on skin and absorbs in seconds with a tingling carbonation sensation. Sounds gimmicky; works in a way you can feel.

8.7/10 · serumiP Interlink Serum
The companion to the Base Care Serum and the second step of Kao's Sofina iP double-serum system — designed to be used after the carbonated Base Care to lock in benefits and add peptide + tranexamic acid + niacinamide treatment work. Where Base Care is the wake-up; Interlink is the treatment. Together they're the J-beauty premium serum protocol that's worth paying attention to.

8.1/10 · tonerSofina Beaute Highly Moisturizing Lotion (Whitening)
Sofina's quasi-drug whitening lotion — tranexamic acid leading the active list (the Japanese pharmacy gold-standard brightening active) plus niacinamide + sodium hyaluronate. The Beauté line is Sofina's anti-aging-meets-brightening platform; this lotion is the daily-routine prep step for the brand's whitening claim.
