Overview
An oily-skinned shopper who wants a hydrating serum without scent gets a natural ampoule here, built around coptis japonica as the one named ingredient.
An unscented serum with a single plant ingredient is a simple choice for oily skin that wants hydration and soothing. Only oily skin is listed, the respiratory entry makes no sense for a face serum, and the ingredient list and directions are missing.
Who it's for
An oily-skin routine that adds one hydrating, unscented serum. Dry or sensitive users have no matching data, and shoppers who want several active ingredients will find only one named.
Pros and cons
- Hydrating and soothing
- Listed for all skin tones
- Oily skin type only
- Respiratory health entry looks wrong
Performance notes
A serum is a thin, concentrated liquid applied before a moisturizer, so the hydrating result depends on how much is used and how it is layered. Coptis japonica is the only named ingredient and no concentration is given. The listing gives no steps, so follow the pack.

Frequently asked questions
How do I use the Pyunkang Yul Moisture Ampoule?
The listing gives no directions. It is a serum, so follow the pack for the amount and the order with other products.
Is the Pyunkang Yul ampoule suited to dry skin?
Only oily skin is listed, so dry skin is not covered by the data.
Why does the Pyunkang Yul ampoule list respiratory health?
The addresses field includes Respiratory Health alongside soothing, toning and moisturizing. That entry does not fit a face serum and looks like a data error.
