Core Functions and Benefits:

• Gentle Exfoliation: Uses a combination of 3% AHA (Glycolic Acid) to remove surface dead skin cells and 3% PHA (Gluconolactone) to target fine flakiness without causing the redness or irritation typical of traditional exfoliants.
• Barrier Support: Formulated with a blend of 5 types of Ceramides and 2% Panthenol (Vitamin B5) to reinforce the skin's lipid barrier, lock in moisture, and prevent transepidermal water loss.
• Skin Preparation: Acts as a "skin-boosting" pre-treatment that refines texture and improves the absorption of subsequent skincare products.
• Makeup Optimization: Smooths rough patches and reduces flakiness to create a long-lasting, flawless base for makeup application. 

Key Ingredients and Properties:

• 3% Glycolic Acid (AHA): A "superstar" exfoliant that helps refine skin texture.
• 3% Gluconolactone (PHA): A larger-molecule acid that exfoliates more gently than AHAs, making it suitable for sensitive skin.
• 5-Layer Ceramide Complex: Includes Ceramide NP, NS, AP, AS, and EOP to mimic the skin's natural barrier.
• 2% Panthenol: Provides soothing and anti-inflammatory benefits to reduce potential irritation from the exfoliating acids.
• Niacinamide: Helps to brighten the complexion and further support barrier health. 

Usage Recommendations:

• Application: Apply one full dropper to clean skin as the first step after cleansing.
• Frequency: While gentle enough for daily use on many skin types, those with highly sensitive or acne-prone skin may prefer using it 2–3 times a week.
• Sun Protection: Due to the high concentration of AHA, always apply sunscreen during the day to protect newly exfoliated skin from UV damage.
