Overview
Layering a few drops of this Cosrx ampoule under a moisturizer is how it fits a routine. Hyaluronic acid is the named key ingredient, the benefit is hydrating, and soothing is the other concern it addresses.
Wide skin-type coverage and a lean free-from list suit a hydration step. The listing gives an aloe scent and a fragrance free tag together, which is worth a second look.
Who it's for
The situation is an oily or combination complexion that still needs water, or a sensitive one that wants a gentle layer. Skip it if you want a rich cream or a serum with a firming active.
Pros and cons

Performance notes
Hyaluronic acid pulls water into the surface of the skin, and layering several molecular sizes is the idea behind a triple formula. A drop-form ampoule is thin, so it goes on before heavier creams. The listing does not say which sizes of hyaluronic acid are included.
