I received this serum from Suzykirei some time ago and used it up! It's a pinkish-colored serum. It addresses five skin concerns for adults, including anti-aging care: 1. Dullness, pores, dryness, uneven texture, and fine wrinkles caused by dryness. It's a thick serum that moisturizes the skin, making it easy to use. After applying it, it feels like it tones up, so I used it with a La Roche-Posay sunscreen primer, which helped my makeup look beautiful.
I received this as a gift from Suzykirei. Thank you. I've seen dermatologists recommend this product on YouTube, and it's reasonably priced, so I have high hopes for it. I've been using it only at night for about a week. The first thing I noticed when I first applied it to my face was the smell of a public restroom... (this is my personal opinion). I've gotten used to it since wearing it every day, but once that thought hits me, it's unbearable and very strong. I've also used La Roche-Posay's Effaclar Peel Care Serum, and the bottles are the same size. The Peel Care Serum is a smooth liquid, while this is thick. Perhaps because of this, it's difficult to draw up with the dropper, and I can only get one drop at a time. I'm using a little at a time, but I'm not sure how much to use, so I'm not sure. I'm still waiting to see the results, but I do notice that the skin on my cheeks is firmer. I'm excited to see the changes. I plan to continue using it daily.
I received this product as a gift from Suzykirei. Thank you. I've used it up, so I'm writing this review. Because I have sensitive skin, I always pay close attention to the ingredients when purchasing skincare products. This brand has many appealing ingredients, such as retinol, niacinamide, and melazil, and since I love their sunscreens, I started using this product with high hopes that it would suit my skin. It felt great to use and I didn't experience any irritation. However, the scent just didn't suit me. This may be because I have a sensitive sense of smell. I preferred the Effaclar Peel from the same brand.
I feel like my skin tone has improved a little since I started using it.
It's turning white!
