Overview
Pyunkang Yul's serum arrives in a 100 ml bottle priced at $26.99, making it one of the larger-volume options in this category. The listed key ingredient is Coptis Japonica, a plant-derived botanical used in Korean skincare for its soothing properties. The formula is fragrance-free and unscented, which is notable for users who find fragrance a trigger for sensitivity.
The product targets oily skin and is described as supporting hydration, soothing, toning, and moisturizing functions. The absence of fragrance is consistent with its positioning as a gentle daily serum, and its listed benefits suggest it is designed as a foundational layer in a multi-step routine rather than a standalone concentrated treatment.
The 718-review base and 4.4-star average reflect consistent satisfaction. For buyers interested in Korean skincare with a simpler, low-irritant ingredient philosophy, this serum offers a practical option at a very reasonable cost per ml.

Performance notes
Coptis Japonica is a botanical extract used in traditional Korean and Asian skincare for its calming and skin-balancing properties. The fragrance-free designation means the formula skips one of the most common sensitizing additives in skincare. The hydrating and soothing benefit profile suits a serum meant to calm and balance oily or reactive skin, though it does not include ingredients typically associated with targeting the visible signs of aging.
What buyers say
With 718 reviews and a 4.4-star average, this serum sits in reliable positive territory. The review count provides a solid sample, and the average suggests most buyers find it effective for its intended soothing and hydrating purpose.

Frequently asked questions
Is 100 ml a lot for a serum?
Yes, 100 ml is significantly more than the typical 30 ml serum, which makes this an unusually good value per ml at the listed price. With standard daily use, a 100 ml bottle should last several months, making it practical for anyone who likes to maintain consistent use of a single serum.
What is Coptis Japonica and why is it used in skincare?
Coptis Japonica is a flowering plant whose root extract has been used in traditional Korean and East Asian preparations for its calming and skin-balancing properties. In modern skincare, it appears in formulas aimed at soothing the look of irritated or sensitized skin. This is not medical advice.
Can this serum be used if you also have some dry patches?
The serum is listed for oily skin and has a hydrating focus, but it does not include richer emollients suited to dry areas. If you have combination skin with dry patches, you may want to layer a separate moisturizer over the serum to address those areas.
