Rice Extract: effective % & pH 쌀
⏱ 1 min read
⚡ Quick answer: Rice Extract: effective concentration varies (extract/ferment; often listed high in essences), optimal pH 4.5–6.5, evidence Limited. Rice extract percentages on K-beauty labels are about the 'glow/mochi' feel of the base, not a measurable active level — there's no consensus effective %.

What the % on the label really means
