I have been using SOS essence and bought it back three times. Let me introduce my situation first. I am a 25-year-old general office clerk with mixed skin. Because I didn't realize that I had to fight aging before, I had several fine lines in my eyes, large pores and rough skin before using SOS essence. When I first got it, I thought the packaging of this essence was quite unique. It is designed to separate the essence from the solution. When I use it, I need to mix the essence with the solution by hydraulic pressure, and then install the matching extrusion head to use it. The texture is clear and concise, very moist and refreshing, not sticky and delicious. It is absorbed quickly after being applied to the face. Then it also contains anti-aging components such as tetrapeptide and hexapeptide. I used it for about a week, and found that the fine lines in the corner of my eyes became shallow and the pores on both sides of my nose became smaller. After using it for almost 1 month, my face became smooth and the fine lines around my eyes disappeared, so happy! It's still in use. After all, anti-aging can't happen overnight. This requires persistence and patience!
