This serum is so unique and effective in boosting circulating that it has become my new favorite serum. The moment this serum touched my skin, it starts to tingle and the more I massage the serum into my skin, the prickling slightly intensifies. My face did not get red but when I applied it to my neck, I didn't feel the prickly so much on my neck did get a slight flush. The prickling feels like when I get a glycolic acid peel but not as intense. I am hoping that this prickling sensation is helping with the circulation on my face. I have dry sensitive skin and since I have been using this serum, my skin has never been so soft. I am definitely reordering this product because I am so impressed with how it works. This product is made in Korea. Read more

This serum works as it should however on my skin the tingling sensation has been too much for me. I had not used this type of product before so maybe I just wasn’t used to it. If you use this type of product regularly it might be for you. If you have sensitive skin like me it may not be a good idea. Read more

When I used this, I can feel the needle feel on my skin as described in the product description, around 15 seconds or so. The skin serum does not feel sticky and leave my skin softer. Love this product. Highly recommend this. Read more
