Core Functions and Benefits:

• Pore Refining and Tightening: Infused with Albumen (egg white extract), the foam helps visibly diminish the appearance of enlarged pores by removing deep-seated grime and creating a tightening film on the skin's surface.
• Sebum Control: It effectively regulates excessive oil production, making it ideal for those with oily or combination skin who struggle with a shiny appearance.
• Deep Impurity Removal: The rich, dense foam washes away pore-clogging dirt, microdust, and dead skin cells to help prevent the formation of blackheads and whiteheads.
• Skin Firming and Smoothing: According to Skinfood, the amino acids and proteins in the egg white stimulate collagen cell growth, which can improve skin elasticity and resilience over time.
• Anti-Acne Support: Contains Salicylic Acid (BHA) and Sulfur, which work together to unclog pores and provide antibacterial effects to help reduce acne breakouts. 

Key Ingredient Technologies:

• 5RG-Pore Eraser™: A complex of tomato, carrot, licorice root, green tea, and Centella asiatica extracts that works to soothe the skin while reducing the visibility of pores.
• Albumen (Egg White Extract): A high-quality protein source rich in vitamins and minerals that purifies pores and firms the skin.
• Moisturizing Agents: Ingredients like Glycerin, Olive Oil, and Egg Yolk Extract are included to help replenish moisture and prevent the skin from feeling overly stripped or tight after washing. 

User Reviews and Expert Insights:

• Cleansing Power: Reviewers on Hwahae and Amazon often praise its "squeaky clean" feel and effectiveness at removing heavy makeup.
• Texture and Lather: Users note that a "pea-sized drop" is sufficient to create a lush, thick foam, making the 150ml tube long-lasting.
• Potential Harshness: While marketed as gentle, some testers with very dry or sensitive skin reported a "stripping" or "tight" sensation if used too frequently, suggesting it may be best as a once-daily or occasional deep cleanser for these types.
