1. Volume: As someone with skin that cracks even in summer, I found the 50ml size to be just right. 2. Application: (I have slightly sensitive, dry skin.) I expected this product to be heavy like other collagen products, but I was surprised by how light and refreshing it felt when applied with one pump. It goes on like a thin, cooling soothing gel with a slight texture. After that, you can feel the collagen's richness locking in moisture both deep and on the surface. 3. Hydration: This product alone seems sufficient for moisturizing. Using two pumps as a baseline, it absorbs into the skin without feeling greasy. It's more hydrating than a toner due to its texture, but it's not quite like an emulsion. Think of it as a deeply moisturizing, elastic serum or essence.

1. Scent: While not unbearable, the initial smell might make you go 'Huh?'. It's not exactly a pleasant fragrance. 2. Caution: One pump feels light, but for nighttime care, it wasn't quite moisturizing enough for my skin. I used two pumps without any other products and was satisfied, but applying more made it feel too heavy. The texture became very rich, leaving my hands feeling sticky and my face feeling like something was constantly clinging to it. I remember having to wash it off and reapply. Using too much might clog pores and cause blemishes, so it's best to find the right amount for your skin.

To provide a thorough review, I used this product exclusively for two weeks. If you have dry skin like mine, for summer use, I'd recommend using an exfoliating toner + one pump of collagen serum before makeup. For nighttime care, try a calming toner + two pumps of collagen serum. This routine worked well for me.
