Purchased as an 80+25ml special package at Costco. Price: About 29,000 won during a discount event. Ingredients: Nothing particularly concerning. Texture: A standard serum consistency, neither too thin nor too thick.
Longevity and effectiveness: It's hard to find standout qualities, but you miss it when you don't use it - that's serums for you. It's unrealistic to expect dramatically visible results, and using this won't magically give you celebrity-perfect skin. I just bought it because it seemed cheaper than Olive Young during the Costco promotion. Dropper: As the product decreases, it becomes difficult to reach the bottom. Value for money: It costs at least 300 won per ml, which makes me think I might be better off just using a good hydrating moisturizer instead.
Buying serums is largely driven by psychological factors. This is a gentle, easy-to-use serum that's decent for everyday use.
