I recommend the Madeca21 Teca Solution Soothing Capsule Ampoule.

I bought this product after seeing a YouTube video praising the Daiso ampoule, and I am very satisfied with it. At 5,000 won, it is really affordable for an ampoule. However, its performance is comparable to expensive ampoules, making it the best value for money! Since it contains Centella Asiatica extract, it is said to be good for hydration and skin moisturization, so I highly recommend it.
