The moment I applied it to my skin, it melted into a smooth consistency, blended well with my skin, and emulsified quickly. Because it has a clay-like texture, I think it's best to massage it in gently. The only drawback is that the spatula can't be stored behind the lid, which I found a little inconvenient. I think this is a product I'd like to purchase once I've finished my current cleanser.
I used the trial size of 3.5g (one dose), which felt like a lot for one use. The scent was also strong. It didn't irritate my skin and left it feeling smooth, so I'm happy with the feel.
It gently and softly removes makeup. There's no tightness after washing, and it's easy to tell that it's gentle on the skin. I notice a difference in how dry my skin is the next morning compared to after washing. I worry a little about whether it really removed all the makeup, so on days when I wear a lot of makeup, I cleanse twice. If you're used to oil cleansers, you'll feel a refreshing sensation as your makeup is removed, so I think it's just a matter of getting used to it.
Overall Review: My skin became as smooth as a boiled egg. I think this product is easy to try even for those who don't like scrubs. The moisturizing power was also excellent, so I'll definitely be buying it again! Pros: - Super smooth!!! → My skin became so smooth after just one use. Even the stubborn areas around my nose and chin were cleared, so I'm very satisfied! It's also moisturizing, so I didn't have to worry too much about the harshness on my skin, which I also liked. - Comfortable to use. → Other products have large scrubs that can be a bit painful, but this one is a fine scrub, so I was able to use it without any discomfort. At first glance, it seemed like it had a firm texture, but when I applied it to my skin, it felt like it melted with body heat, which was very comfortable. Cons: - The instructions in the pamphlet were confusing. → I looked at the included pamphlet, but it was hard to understand what each product did.
I received this product as a gift from Suzykirei. I've been interested in it, so I'm very happy. The product description describes it as a gently exfoliating micro-particle scrub and adsorbent clay. I applied it to my skin and rubbed it in for about a minute, and it absorbed smoothly without any friction. After carefully rinsing it off about 20-30 times, my skin felt soft and smooth, like a peeled egg, without any tightness. The finish was excellent. It's supposed to be used in place of your regular cleanser, even on makeup-free days, but I use it whenever my skin feels rough or on makeup-free days. As for whether it's good value for money... I think it would be easier to buy again if it were just a little cheaper. I'll probably use it in conjunction with other cleansers depending on my skin condition and the amount of makeup I wear.
