Cosrx is tried and true
Cosrx has been a staple in my skincare as long as I have been using korean beauty products. This does not disappoint. My skin does tend to be on the oily side so I do not use as much of this as I should, but it's a keeper.

Ideal for dry skin.
While I love ascorbic acid-containing vitamin c serums, they do tend to be a bit drying. I have dry skin, & can counter this by layering something moisturising - it's nice that this product provides the benefits of ascorbic acid but also provides moisture. I appreciate the addition of all the other antioxidants as well. This is absolutely perfect for my dry skin in dry Aussie summers when I need vitamin c & moisture at the same time.
