What it is
Aiming for a texture with just the right amount of viscosity and slip, this product is intended for use as a massage before applying makeup, and we paid particular attention to achieving a smooth finish without the thick, filmy feeling that can cause makeup to slide and crease, or the stickiness that can cause uneven application.

I massaged my face with the sponge and this serum for a week, and I realized how much waste had accumulated on my face. My cheeks lifted and looked revitalized! My nasolabial folds also seemed to have faded. I noticed the same thing when I massaged my body, but I think a stronger massage makes the skin firmer.
I bought it without any expectations, but it was actually quite good. It feels good to use and leaves my skin feeling smooth.
I received this as a gift from Suzykirei. It's supposed to be used to massage the blood flow around the eyes and chin before applying makeup. It also came with a dedicated sponge. The serum bottle has a luxurious feel to it, which I really liked. I actually used it before applying makeup. The sponge is fairly soft, but I felt like it could be a little softer on the skin. Even when massaging gently, it felt like it caused a bit of friction. The serum itself was a little thick, but nothing particularly special. After massaging, I wondered if the dark circles around my eyes had lightened... but I couldn't really tell.
A neighbor in her 70s has beautiful, firm skin with no wrinkles, so I asked her what she does and she told me she uses this serum to massage the blood flow, so I bought it along with the sponge. When I massage with the sponge in the morning and at night, my skin becomes firmer and the area around my eyes and face line become firmer. It also reduces puffiness, which I thought was great. I'd like to continue using it for a while.
