(Purchased with my own money) Bioderma Hydrabio Serum

The theme of this week's "Purchased with My Own Money" is that they say they absolutely must use this product even if it's expensive!

I recommend the Bioderma Hydrabio Serum. We are currently in the transitional season, with chilly mornings and evenings, and the dryness is really bothering my skin. This Bioderma Hydrabio Serum is excellent for replenishing moisture. I buy it at Olive Young, as well as through direct overseas purchases or at duty-free shops. While it isn't expensive as a single item, the quantity is small, so I have to buy it frequently and try to use it sparingly. It has a fresh, non-sticky texture and is a high-density hydration serum. It is even better because the moisture lasts all day long.
