My first purchase of Korean cosmetics. It was well absorbed. Overall I rate it positively, but I will try another brand 😉

The serum is light, I use it as the first step after cleansing my skin, it prepares my skin nicely for other products, it suits me, I have dry sensitive skin, it doesn't irritate, I can only recommend it, age 38

It's just a mega ampoule, it made my skin very moisturized and reduced wrinkles 🥰

I used it as the first step after washing my face and it was great at hydrating. Gradually, after adding it to my routine, I also noticed an overall brightening of my skin, but that can't be attributed purely to this product, as I use more products. There's a really large amount, so when used twice a day, it lasted me about 10-11 months. I originally bought it from another e-shop, but the price here is now significantly better. If it's around 400 CZK, I wouldn't hesitate to buy it.

I've been using this booster since I started using Korean skincare. Combined with other active ingredients, it has eliminated my post-inflammatory blemishes.

A very pleasant hydrating product with a watery texture that absorbs nicely into the skin and prepares it for the next steps👍. I would call it more like a base for a serum, it certainly does not meet the properties of a complex serum (at least for oily young skin).
