Key Ingredients

サリチル酸(BHA) 2%
Penetrates inside pores to dissolve sebum plugs. Promotes natural desquamation and refines texture.
グリーンティーエキス
Polyphenols (EGCG) provide antioxidant protection against UV-induced oxidative stress.
メチルプロパンジオール
Penetration enhancer improving active ingredient delivery into the skin.

How It Works

2% salicylic acid loosens desmosome bonds between corneocytes, promoting natural shedding of dead skin cells (chemical exfoliation). Being oil-soluble, BHA penetrates oily pore interiors to dissolve comedones and normalize pore turnover. Long-term use promotes uniform epidermal differentiation, improving surface texture and radiance. pH 3.2-3.8 optimized for maximum keratolytic efficacy.

How to Use

After cleansing and toner, apply appropriate amount to cotton pad or palm and smooth evenly over face. Start with twice weekly (PM only), gradually increase to daily. Always follow with moisturizer.

Expected Results

Reduced roughness and smoother feel at 1-2 weeks. Refined texture and reduced visible pores at 4-6 weeks. Even skin tone and dramatically improved makeup application at 2-3 months.
