Keana Nadeshiko Baking Soda Scrub Wash 100g

Keana Nadeshiko Baking Soda Scrub Wash 100g is a baking soda-based scrub cleanser for oily and congested skin with visible blackheads and rough pore texture — using sodium bicarbonate (baking soda) particles that dissolve into the skin's moisture during washing and convert into a gentle carbonic acid that softens keratin plugs inside pores. The scrub particles provide simultaneous physical exfoliation of the pore opening surface.

• Sodium Bicarbonate (Baking Soda) — dissolves in the skin's natural moisture to form carbonic acid that softens and loosens keratin plugs in pores
• Scrub particles — physical exfoliants that remove the loosened surface debris from pore openings during cleansing
• Mild cleansing base — removes impurities without over-stripping the moisture barrier
• Dual action — chemical (baking soda carbonic acid) and physical (scrub) in a single wash step
• 100g — concentrated formula; a small amount generates sufficient lather for a full-face wash

How it works: Baking soda (alkaline) reacts with the mildly acidic environment on the skin surface to release CO₂ and form a brief carbonic acid environment. Carbonic acid has mild keratolytic properties — it softens the protein bonds holding keratin plugs inside pores without requiring the pH of professional AHA peels. The simultaneous scrub particles mechanically clear the softened material from the pore opening during the washing motion.

Baking soda scrub vs enzyme cleansers for blackheads: Enzyme cleansers (Suisai, Orbis POA-TULU) dissolve pore plugs chemically from within — effective for deep congestion. Baking soda scrubs (this product) combine mild chemical softening with surface physical exfoliation — more effective for surface blackheads and rough pore texture at the opening. For both deep pore clearing and surface exfoliation, use both: enzyme cleanser daily, baking soda scrub 2–3 times weekly.
