Specially formulated for sensitive skin, this gentle exfoliating essence combines lactobionic acid (PHA) with mandelic acid and tartaric acid in a golden ratio to effectively smooth rough, congested skin, reduce enlarged pores, and revive dull, uneven tone. Infused with ceramides, panthenol (pro-vitamin B5), dipotassium glycyrrhizate, and chamomile extract, it deeply hydrates and calms the skin to minimize irritation commonly associated with acid-based treatments.

Alcohol-free. Fragrance-free. Colorant-free. Safe for sensitive skin.

 • Lactobionic Acid (PHA) :
A gentle, water-soluble exfoliant that refines dead skin cells while enhancing hydration and reducing dryness or tightness caused by acids.

 • Ceramides
Known as the “moisture king,” ceramides strengthen the skin’s protective barrier and boost hydration with both water- and oil-binding properties.

 • Provitamin B5 (Panthenol)
Biocompatible with the skin’s lipid barrier, it offers excellent hydration and soothing benefits—helping to calm and nourish dry, irritated skin.

 • Dipotassium Glycyrrhizate
A potent anti-inflammatory agent that soothes skin and enhances moisture retention, leaving skin soft and supple.

After cleansing, apply an appropriate amount of AHA PHA Refining Serum evenly to the entire face. Focus on areas prone to blackheads or congestion, such as the T-zone and chin. Gently pat until fully absorbed, then continue with your usual skincare routine. ‧ For oily or normal skin: use morning and night. ‧ For dry or sensitive skin: recommended for evening use only.

**Do not use in combination with other exfoliants or acid-based products to avoid skin damage.
