Overview
HKH Serum ships in capsule form and is labeled unscented, fragrance free and alcohol free for all skin types. Amazon has not provided a seller description or an ingredient list for this listing.
Capsule serums package a single dose per unit, which some people prefer over a dropper bottle that is easy to over pour. Because HKH has not published a description or ingredient list here, the rating and review count stand as the main signal rather than formula detail. The alcohol free, fragrance free label is worth noting for anyone with reactive skin.

Who it's for
Suited to shoppers who want a fragrance free, alcohol free serum in single dose capsules rather than a bottle. Less useful for anyone who wants to research active ingredients before buying, since none are listed.
