Product features
According to retailers such as YesStyle, the Medicube serum is made with a combination of active ingredients: 
Kojic Acid: A skin-lightening agent derived from fungi, it helps to fade uneven skin patches and hyperpigmentation by inhibiting melanin production.
Turmeric Extract: Containing the active compound curcumin, turmeric has antioxidant and anti-inflammatory properties that help soothe irritated skin and reduce redness.
Niacinamide (Vitamin B3): This ingredient refines skin texture, supports the skin's moisture barrier, and helps enhance overall skin tone.
Glow Capsules: The formula includes snowflake-like micro-capsules that contain squalane and thioctic acid. These break upon contact with the skin to help improve absorption and provide hydration.
